The Architect’s Role in Sustainable Design (and How to Use Technology & Innovation to Advance Our Green Agenda) #ilmaBlog #green #design #architecture

Background

In the design and construction field, there are two major categories of resources: renewable and non-renewable. As opposed to non-renewable resources, which are depleted with their constant use, renewable resources are not. If not managed properly Non-renewable resources might become non-existent when the rate at which they are used is much higher than the rate at which they are replaced. Renewable resources include water, geothermal energy and wind energy. Non-renewable resources include coal, natural gas and oil.  The demand for new construction is on the rise as the world’s population increases and the demand for newer, more efficient modern buildings also increase.

Architect’s Role

Because buildings account for so much energy to build and maintain, architects and designers have become very conscious about our role in minimizing our environmental footprint when we design buildings.  The American Institute of Architects, the largest organization of architects world-wide has a committee called the Committee on the Environment (COTE), which works to advance, disseminate, and advocate—to the profession, the building industry, the academy, and the public—design practices that integrate built and natural systems and enhance both the design quality and environmental performance of the built environment. COTE serves as the community and voice on behalf of AIA architects regarding sustainable design and building science and performance.

Bamboo

Renewable Resources

In green construction processes, there is an emphasis on the use of renewable resources. In many cases, this natural source becomes depleted much faster than it is able to replenish itself, therefore, it has become important that buildings make use of alternative water sources for heating, hot water and sewerage disposal throughout their life cycles, to reduce use and conserve water supplies.

Architects and designers specify rapidly renewable materials are those that regenerate more quickly than their level of demand. Our goal is to reduce the use and depletion of finite raw materials and long-cycle renewable materials by replacing them with rapidly renewable ones.  Some commonly specified rapidly renewable materials include cork, bamboo, cotton batt insulation, linoleum flooring, sunflower seed board panels, wheat-board cabinetry, wool carpeting, cork flooring, bio-based paints, geotextile fabrics such as coir and jute, soy-based insulation and form-release agent and straw bales. Some green building materials products are made of a merger of rapidly renewable materials and recycled content such as newsprint, cotton, soy-based materials, seed husks, etc.

Check out this ILMA article about “Materiality and Green Architecture: The Effect of Building Materials on Sustainability and Design” for more information on this topic.

Responsibility of Architects

Architects and designers who align with AIA’s COTE objectives, (1) recognize the value of their role in environmental leadership to advance the importance of sustainable design to the general public while incorporating sustainable design into their daily practice, (2) influence the direction of architectural education to place more emphasis on ecological literacy, sustainable design and building science, (3) communicate the AIA’s environmental and energy-related concerns to the public and private sectors and influence the decisions of the public, professionals, clients, and public officials on the impact of their environmental and energy-related decisions, (4) educate other architects on regulatory, performance, technical and building science issues and how those issues influence architecture, (5) educate the architectural profession on programming, designing, and managing building performance, (6) investigate and disseminate information regarding building performance best practices, criteria, measurement methods, planning tools, occupant-comfort, heat/air/moisture interfaces between the interior and exterior of buildings, (7) promote a more integrated practice in order to achieve environmentally and economically efficient buildings. One of the tools we will plan to promote to achieve this integration is Building Information Technology (BIM).

Smart-Building

The Role of Technology & Innovation – A Case Study (“The Edge”)

PLP Architecture and the Developer OVG Real Estate, built “The Edge” is a 430,556 SF (40,000m²) office building in the Zuidas business district in Amsterdam. It was designed for the global financial firm and main tenant, Deloitte. The project aimed to consolidate Deloitte’s employees from multiple buildings throughout the city into a single environment, and to create a ‘smart building’ to act as a catalyst for Deloitte’s transition into the digital age.

They key features of this building include the following innovations which address the environmental impact of building such a large edifice:

  • Each facade is uniquely detailed according to its orientation and purpose.
    • Load bearing walls to the south, east and west have smaller openings to provide thermal mass and shading, and solid openable panels for ventilation.
    • Louvers on the south facades are designed according to sun angles and provide additional shading for the office spaces, reducing solar heat gain.
    • Solar panels on the south facade provide enough sustainable electricity to power all smartphones, laptops and electric cars.
    • The North facades are highly transparent and use thicker glass to dampen noise from the motorway.
    • The Atrium façade is totally transparent, allowing views out over the dyke, and steady north light in.
  • The building’s Ethernet-powered LED lighting system is integrated with 30,000 sensors to continuously measure occupancy, movement, lighting levels, humidity and temperature, allowing it to automatically adjust energy use.
  • 65,000 SF of solar panels are located on the facades and roof, and remotely on the roofs of buildings of the University of Amsterdam – thereby making use of neighborhood level energy sourcing.
  • The atrium acts as a buffer between the workspace and the external environment. Excess ventilation air from the offices is used again to air condition the atrium space. The air is then ventilated back out through the top of the atrium where it passes through a heat exchanger to make use of any warmth.
  • Rain water is collected on the roof and used to flush toilets and irrigate the green terraces in the atrium and other garden areas surrounding the building.
  • Two thermal energy wells reach down to an aquifer, allowing thermal energy differentials to be stored deep underground.
  • In The Edge a new LED-lighting system has been co-developed with Philips. The Light over Ethernet (LoE) LED system is powered by Ethernet and 100% IP based. This makes the system (i.e. each luminaire individually) computer controllable, so that changes can be implemented quickly and easily without opening suspended ceilings. The luminaires are furthermore equipped with Philips’ ‘coded-light’ system allowing for a highly precise localization via smartphone down to 8 inches (20 cm) accuracy, much more precise than known WiFi or beacon systems.
  • Around 6,000 of these luminaires were placed in The Edge with every second luminaire being equipped with an additional multi-sensor to detect movement, light, infrared and temperature.
  • The Philips LoE LED system was used in all office spaces to reduce the energy requirement by around 50% compared to conventional TL-5 Lighting. Via the LoE system daily building use can be monitored. This data is fed to facility managers via the BMS allowing:
    • Remote insight into the presence of people in the building (anonymous). Heating, cooling, fresh air and lighting are fully IoT (Internet of Things) integrated and BMS controlled per 200 sqft based on occupancy – with zero occupancy there is next-to-zero energy use.
    • Predictions of occupancy at lunchtime based on real time historical data and traffic and weather information to avoid food-waste.
    • Unused rooms to be skipped for cleaning.
    • Managers to be alerted to lights that need replacing.
    • Notification of printers needing paper.
  • Every employee is connected to the building via an app on their smartphone. Using the app they can find parking spaces, free desks or other colleagues, report issues to the facilities team, or even navigate within the building.
  • Employees can customize the temperature and light levels anywhere they choose to work in the building via the mobile app. The app remembers how they like their coffee, and tracks their energy use so they’re aware of it.
  • The vast amount of data generated by the building’s digital systems and the mobile app on everything from energy use to working patterns, has huge potential for informing not only Deloitte’s own operations, but also our understanding of working environments as a whole. Discussions are currently ongoing regarding the future of this data and its use for research and knowledge transfer.
  • The green space that separates the building from the nearby motorway acts as an ecological corridor, allowing animals and insects cross the site safely.

Conclusion

Because buildings account for nearly 40 percent of global energy consumption, architects and designers have been working to impact the built environment in a positive way.  Although not every project can be as green as The Edge, by selecting materials that are renewable while reducing energy are two big contributions we can make to help ease the increasing demand for construction.

Technology can play a big part in our role to design more sustainable buildings through the use of building information modeling, energy management software, building management software, online sustainability calculators, energy modeling software, new lighting innovations, new techniques to capture and deliver energy and clean water while reducing waste, and mobile applications utilizing IoT.

Glossary of Green Terminologies

The following is a quick reference guide to get you started understanding the jargon associated with green design and construction. We hope you find it useful.

1,000 ppm

One thousandth parts per million is the minimum disclosure threshold. Manufacturer measures and discloses all intentionally added ingredients and residuals that exist in the product at 1000 ppm (0.1%) or greater. These may  trigger a GreenScreen Benchmark (BM-1 or LT-1) or Possible Benchmark 1 (BM-P1 or LT-P1).

10,000 ppm (As per MSDS)

Manufacturer discloses all intentionally added ingredients and residuals that exist in a product. This is the threshold that is required by current MSDS standards

100 ppm

One hundred parts per million is the ideal disclosure threshold. Manufacturer measures and discloses all intentionally added ingredients and residuals that exist in the product at 100 ppm (0.01%) or greater. These may trigger a GreenScreen Benchmark (BM-1 or LT-1) or Possible Benchmark 1 (BM-P1 or LT-P1).

Accessory Materials

Used for the installation, maintenance , cleaning and operations materials; including materials recommended by warranty. For example, if a carpet requires a specific type of adhesive. The adhesive would be the accessory materials.

Assessment

the evaluation of the toxicological properties (hazards) of chemicals; evaluates exposure and risk assessment in relation to both environmental and human health scenarios.

Associated Hazard

disclosure of the health hazards associated with each ingredient; Portico uses a minimum set of authoritative chemical hazard lists against which ingredients are screened for human health and environmental hazards.

Asthmagen

Asthmagens are substances that are known to cause or exacerbate asthma. Asthma is a complex disease, and there is not enough evidence to point to any single cause. Public health agencies often report dust, pet dander, environmental air pollution, tobacco smoke, respiratory infections, mold, exercise, and stress as common triggers of asthma attacks.

Health organizations have also identified a number chemical asthmagens, including many that are commonly used in building materials, such as floorings, insulations and cabinet substrates. These chemicals include: formaldehyde, toluene, styrene, BPA and certain phthalate plasticizers.

Despite better management of asthma through medication, improved outdoor air quality and a dramatic decline in tobacco smoking, the incidence of asthma has continued to rise, especially in children — and in particular among children who are living in poverty.

Authoritative chemical hazard lists

a list of chemicals and their association to human health or environmental hazards. These lists are created by an expert assessment of scientific evidence by a recognized authoritative body.

Biobased

“Biobased” is a term used in the marketing materials of many types of products. While biobased technically describes a product made from a living material (soybean oil, wool, etc.) marketing materials may stretch this definition to include minerals or other naturally occurring materials that aren’t renewable, or suggest that an entire product is made of biobased materials, when in fact only a small percentage of the product is.

Blowing Agent

A class of chemicals that can generate foam in materials, such as those used in insulation, which later harden or solidify into long-lasting structures. Many are known to possess extremely high global warming potential; chlorofluorocarbons (CFCs) have been mostly eliminated from new production since the 2000s, but hydrofluorocarbons (HFCs) are still prevalent. Blowing agents, as a class of products used in building product manufacture, are in an active transition toward healthier and more environmentally friendly options.

CAS Number

chemical abstract service number is a unique numerical identifier for every chemical described in open scientific literature of elements, chemical compounds, polymers and other substances.

Carcinogen/Cancer

Can cause or contribute to the development of cancer.

Characterization

identification and disclosure of ingredients and all hazards associated with ingredient components in the product/material formulation.

Common Product Profile

A profile of a generic, non-manufacturer-specific product type that contains: a brief description of the product type, the expected composition of the product based on publicly available sources, and corresponding health hazards inherent to this composition. Common Product Profiles (CPs) developed as part of the Quartz Project include additional information about the life cycle of the product, such as its contribution to global warming. See http://www.quartzproject.org/ for more information on CPs.

Developmental Toxicant

Can cause harm to a developing child, including birth defects, low birth weight, and biological or behavioral problems that appear as the child grows.

Disclosure Threshold

the level at which all intentionally added ingredients and residuals in the product/material formulation are disclosed (1,000 ppm, 100 ppm, or other). Different standards require specific disclosure threshold. MSDS (Materials Safety Data Sheets require minimum of 10,000ppm.

Endocrine/Hormone Disruptor

Can interfere with hormone communication between cells which controls metabolism, development, growth, reproduction, and behavior (the endocrine system). Linked to health effects such as obesity, diabetes, male reproductive disorders, and altered brain development.

Environmental Attributes

this information can be found in an EPD, LCA, or other studies of global warming impact, carbon content, and embodied energy. We recommend providing this information (when available) because it will be helpful for LEED and LBC regional credit documentation and carbon accounting.

Flame Retardants

Flame retardants are chemical additives to building products that reduce their flammability. They are commonly found in textiles, plastics, coatings, finishes and foams. Halogenated flame retardants – those made with chlorine or bromine – are particularly toxic to human health, and the planet.

Flue-Gas Desulfurization (FGD)

Flue-gas desulfurization is an environmental control technology installed in the smokestacks of coal-fired power plants designed to remove pollutants from the air. These controls are also called “scrubbers”. Once the scrubbers are full of sulfur dioxide, they are often used to create synthetic gypsum. FGD gypsum can be used in drywall, but also in concrete and other applications where mined gypsum can be used. FGD can contain heavy metals such as mercury that can be released into the air when it is incorporated into these products.

Formaldehyde

Formaldehyde is a colorless gas used as a preservative and disinfectant in the building industry, and in the manufacture of polymers. Formaldehyde is carcinogenic, irritates the eyes, nose, and lungs, and is known to react with other atmospheric chemicals to produce the deadly gas carbon monoxide. Formaldehyde is used in some paints and adhesives, in some fabric treatments, and, significantly, in the manufacture of polymeric binding resins used in a wide variety of building products. Phenol formaldehyde, urea formaldehyde, and melamine formaldehyde are all known to release formaldehyde over time long after product installation in residential and commercial spaces.

Global Warming

Can absorb thermal radiation, increasing the temperature of the atmosphere and contributing to climate change.

Global Warming Potential (GWP)

Known as “greenhouse gasses,” certain gasses have the ability to warm the earth by absorbing heat from the sun and trapping it the atmosphere. Global Warming Potential is a tool that allows scientists to compare the severity of greenhouse gasses based on how much heat they can trap, and how long they remain in the atmosphere. By using carbon dioxide for each comparison, a larger GWP number, the more a gas warms the earth, and contributes to climate change.

Look for GWP data on Environmental Product Declarations, and learn more about interpreting these numbers at http://www.epa.gov/ghgemissions/understanding-global-warming-potentials.

GreenScreen

short for “GreenScreen for Safer Chemicals”, a chemical disclosure and assessment standard  developed by Clean Production Action to rank chemicals along a four point scale between the most toxic chemicals and the most benign to guide substitution efforts.

HPD

also known as Health Product Declaration. It is a standardized format that allows manufacturers to share contents of their products, including any hazardous chemicals.

HPD-1

status marked for products that have a Health Product Declaration with full ingredient and hazard listings and a hazard translator with a disclosure threshold of 1000 or 100 ppm; can contain LT-1 scored components

HPD-2

status marked for products that have a Health Product Declaration with full ingredient and hazard listings and a hazard translator with a disclosure threshold of 1000 or 100 ppm; can NOT contain LT-1 scored components

HPD-Partial

status marked for products that have a Partial Health Product Declaration and have characterization of hazards and hazard translator for ingredients; exceptions are acceptable with a disclosure threshold of 1000 ppm

Hazard

Hazard is an intrinsic property of a substance – its potential to harm humans or some part of the environment based on its physical structure and properties. We can assess the hazard of a chemical or material by reviewing the scientific evidence for the specific kinds of harm that a substance can cause (often called the endpoints), such as damage to the human reproductive system, or the onset of asthma. On HomeFree, hazards are displayed with a color indicating the level of concern for each one. Purple is the highest level of concern, followed by red, and then orange.

Because very few products on the market are made with ingredients that have no hazards, you should expect to see hazards called out, even for products that are considered healthier options. The trick is to compare hazards between products, and whenever possible, prefer the product with fewer hazards.

Health Endpoint

A disease symptom or related marker of a health impact on a human or other organism. Examples of human health endpoints include carcinogenicity (causes cancer), reproductive and developmental toxicity, respiratory sensitization, etc. Health endpoints are due to the inherent hazards of a substance, and are determined by authoritative bodies, such as the US EPA or the National Institutes of Health.

Information Request Sent

this means that an email letter has been sent to the manufacturer requesting information about a specific product. This IR may ask the manufacturer to share HPD type data, a GreenScreen Assessment, or a C2C certification in order to meet Google’s Healthy Materials criteria

Intentional Content

each discrete chemical, polymer, metal, bio-based material, or other substance added to the product by the manufacturer or supplier that exists in the product as delivered for final use requires its own line entry and must account for over 99% of the total product. To add content you may enter it by using a CAS registry number, chemical name, abbreviations, common/ trade names, genus/species (for biobased materials), product or manufacturer name (for components)

Inventory

list of product contents, ingredients

Lifecycle

In biology, the term “lifecycle” describes the arc an organism undergoes from birth, through stages of growth and development, to its death. When applied to building products, “lifecycle”describes the arc that chemicals or materials take from the extraction of the raw materials needed for their creation, through their synthesis and inclusion in a building product, the period of time that the product is installed in a building, its eventual removal from the building, and its disposal/reuse/recycling at the end of its useful life. Products (and the chemicals and materials used to make them) often present human and environmental health hazards at any step in this lifecycle.

Material Health

listing the ingredients and present chemical hazards of a product and optimizing towards safer materials

Mutagen

Can cause or increase the rate of mutations, which are changes in the genetic material in cells. This can result in cancer and birth defects.

Optimization

the absence of any “chemicals of concern” in the product/material formulation.

Ozone Depletion

Can contribute to chemical reactions that destroy ozone in the earth’s upper atmosphere.

PBTs

Persistent, Bio-accumulative Toxicants; these are chemicals that are toxic, persist in the environment, bioaccumulate in the food chains, and consequently pose risks to the human health and environment

Persistent Bioaccumulative Toxicant (PBT)

Does not break down readily from natural processes, accumulates in organisms, concentrating as it moves up the food chain, and is harmful in small quantities.

Portico

formerly known as the Healthy Materials Tool; is a new portal for entering and accessing building  product data. Portico is a database that allows project teams unparalleled access to a vast selection of building products. Portico automatically screens manufacturer product information so that products are available in front of Google’s design teams right away.

Predicted from Process Chemistry

Fully disclosed projected residuals based on process chemistry. This option is suggested for manufacturers without the capability of measuring actual residuals. Indicate the tool or other basis for prediction in the Disclosure Notes. The HBN Pharos tool is an example of a tool that predicts potential residuals.

Publish

share HPD information solely to Google, not to general public. If public, please share public URL in the transparency section

Reproductive Toxicant

Can disrupt the male or female reproductive systems, changing sexual development, behavior or functions, decreasing fertility, or resulting in loss of a fetus during pregnancy.

Residual Content

the by-product of a reaction of two or more chemicals that are used in the manufacturing process; known as trace substances remaining in the product from manufacturing steps (such as monomers and catalysts) or contaminants that come with raw materials. Residuals can be known from testing as well as estimated from process chemistry assessment. Predicted from Process Chemistry definition noted above.

Respiratory Sensitization/Asthmagen

Can result in high sensitivity such that small quantities trigger asthma, rhinitis, or other allergic reactions in the respiratory system. This can can exacerbate current asthma as well as cause the disease of asthma.

Screening

review contents against authoritative chemical hazard lists. Health Product Declaration standard uses screening as a pathway to understand and assess products for any human health hazard endpoints.

Self-declared

a product disclosure and screening/assessment which is created “in-house” by the manufacturer of the product, and does not utilize a third party assessor.

Third Party Assessor

an independent assessment body which is not affiliated with the manufacturer or the product.

Tint

Tints are a mix of pigments and other ingredients that give paints their distinct color. These tints can be a substantial source of VOC content in addition to whatever VOCs are in the paint itself. Darker and richer colors will tend to be higher in VOC content. Some manufacturers have developed low or zero VOC tint lines that can be used to insure that a low VOC paint product remains so even in dark or rich colors.

Transparency

the level of product/material formulation information (including ingredients names and associated hazards) being shared by the manufacturer with the end users (i.e. public, third party, Google).  Portico’s transparency category gives points to manufacturers who share product information (HPD) publicly rather than just to Google.

VOC

Volatile Organic Compound

VOC Content

provide the regulatory VOC content  for liquid/wet applied product in g/L; if the VOC content has not been third party certified and there is no standard for the product, indicate “none” on the VOC content line. If the product is not wet applied, indicate N/A

VOC Emission

emissions testing and certification for any product for which the current version of the CDPH (CA Department of Public Health) Standard Method provides emission scenarios

VOCs

Volatile organic compounds (VOC) means any compound of carbon (excluding carbon monoxide, carbon dioxide, carbonic acid, metallic carbides or carbonates, and ammonium carbonate), which react in the atmosphere in the presence of sunlight.

Verification

assessments verified by an independent, third party assessor, in compliance with specific requirements pertaining to the standard at hand.

Zero VOC

5 g/L cutoff threshold recognized by SCAQMD for products that are Zero VOC

ppm

parts per million (1,000 ppm = 0.1%; 100 ppm = 0.01%).

Green Specification Guidance

GENERAL

● Include a requirement in specifications that contractors and subs review HomeFree.

● Ask for and prefer products that have a Health Product Declaration (HPD).

● Avoid products marketed as antimicrobial and claiming or implying a health benefit.

FLOORING

● Prefer non-vinyl flooring products.

● When vinyl is used: Specify phthalate-free; avoid post-consumer recycled content.

● For rubber flooring: Avoid post-consumer recycled content (crumb rubber).

● For carpets: Look for products that don’t use fluorinated stain-repellent treatments; specify backings that are vinyl-free and polyurethane-free and do not contain fly ash.

● For ceramic tiles, prefer those made in the USA where most manufacturers have eliminated toxic lead compounds from ceramic tile glazes. Avoid post-consumer recycled content from CRTs (cathode ray tubes) which contain high concentrations of lead.

INTERIOR PAINT

● Prefer paints that meet the Green Seal-11 (GS-11) standard from 2010 or later whenever possible or specify paints known to be free of alkylphenol ethoxylates (APEs).

● Specify bases with 10 g/L of VOCs or less and colorants that do not increase the overall VOC content.

● At a minimum, specify paint bases and colorants with a VOC content of 50g/L or less.

● Look for paints that have VOC emission testing and meet the requirements of the CDPH (California Department of Public Health) Standard Method for Testing VOC Emissions (01350).

DRYWALL

● Specify boards made with natural gypsum.

● If possible, avoid pre-consumer recycled content (also known as synthetic gypsum or FGD) to avoid the release of mercury in manufacture.

THERMAL INSULATION

● Specify residential fiber glass batt insulation — it has been reformulated to be free of formaldehyde — or formaldehyde-free mineral wool batts. Unfaced batts are most preferable.

● For blown insulation, prefer cellulose or un-bonded fiber glass.

● Consider alternatives to rigid board insulation whenever possible. If board insulation is required, specify mineral wool boards and look for those that meet the requirements of CDPH Standard Method for Testing VOC Emissions (01350) for residential scenarios. If plastic foam insulation is used, look for those that are halogen-free. Consider upgrading to expanded cork insulation.

● Avoid spray polyurethane foam (SPF) insulation whenever possible.

● For sealing applications, prefer caulking or sealant tapes to spray foams.

COUNTERTOPS

● Think of countertops as a system of products: the surface itself, an adhesive, and potentially a surface treatment, which may need to be re-applied regularly. Each of these elements have different health concerns.

● Sealant products can introduce hazardous chemicals. Specify countertops that do not need to be sealed after installation, such as engineered stone, cultured marble, or solid surfacing.

● Plastic laminate is not a top countertop choice, but if used, specify that the substrate be made with NAF (No Added Formaldehyde) or ULEF (Ultra Low Emitting Formaldehyde) resins. © Healthy Building Network [June 2018]

CABINETRY & MILLWORK ​+​ DOORS

● Prefer solid wood products over composite.

● When using composite wood, specify materials that are NAF (No Added Formaldehyde) or ULEF (Ultra Low Emitting Formaldehyde) whenever possible.

● Prefer products that are factory-finished.

● For edge-banding, specify products with veneer rather than vinyl.

WELL Communities: Health & Wellness Lifestyle

Architects need to continue to consider healthy living when designing private and public spaces.  According to the sources cited below, the Well Living Lab aims to answer critical questions to make homes, offices and independent living environments healthier places. That means indoor environments could be altered to reduce stress and increase comfort, performance and sleep.

By understanding the interplay of elements such as sound, lighting, temperature and air quality, indoor spaces may be altered to address people’s specific and overall health needs. And by understanding how people’s behavior is shaped by their physical environment, facilities can be designed to maximize positive health habits and reduce negative influences. This ambitious three-year research plan is the start toward transforming human health and well-being in indoor environments.

13 Examples of Green Architecture

The Morris & Gwendolyn Cafritz Foundation Environmental Center

The nickname for the Morris and Gwendolyn Cafritz Foundation Environmental Center is the Grass Building, and it perfectly captures its spirit. It’s a structure so thoughtfully designed it’s almost as energy-efficient and low impact as the greenery that surrounds it.

The Maryland building is part of an educational farm on the Potomac River Watershed that the Alice Ferguson Foundation used to teach people about the natural world. This new building—which became the 13th in the world to receive full Living Building Challenge certification in June 2017—is an educational facility designed to blur the lines between indoors and out, while still providing shelter as needed. “Part of the intent of the building is to be in the landscape and still have a bathroom to use,” says Scott Kelly, principal-in-charge at Re:Vision, a Philadelphia-based architecture and design studio.

Brock Environmental Center

Drawing thousands of students, the Brock Environmental Center is a regional hub for the Chesapeake Bay Foundation, in Virginia Beach, Virginia, supporting its education and wetlands restoration initiatives. A connection to nature defines the building’s siting, which provides sweeping views of the marsh and also anticipates sea-level rise and storm surges with its raised design. Parts were sourced from salvage: Its maple floors once belonged to a local gymnasium while school bleachers, complete with graffiti, were used for interior wood trim. The center was recognized for its positive footprint: It has composting toilets, captures and treats rainfall for use as drinking water, and produces 80 percent more energy than it uses, selling the excess to the grid.

Discovery Elementary School

Students have three distinct, age-appropriate playgrounds—with natural elements such as rocks and fallen trees—at Arlington, Virginia’s Discovery Elementary School. The name honors astronaut John Glenn, who returned to space on the Discovery shuttle and once lived in the neighborhood. Exploration is a theme at the school, whose interior focuses on forests, oceans, atmosphere, and the solar system. The largest zero-energy school in the country, it offers “hands-on learning around energy efficiency and generation,” jurors noted. The school maximizes natural light and provides views to the outside in all classrooms.

Bristol Community College

A laboratory is an energy-intensive enterprise, with specialized lighting and ventilation needs. That’s why jurors praised the airy health and science building at Bristol Community College, in Fall River, Massachusetts, for its net-zero energy achievement, “a difficult feat,” they noted, “in a cold climate like New England’s.” The move saves $103,000 in annual operating costs and allows the college, which offers a suite of courses in sustainability and energy, to practice what it teaches. Part of a holistic campus redesign, the new building’s location increases the density—and thus walkability—of campus for students.

Central Energy Facility

Orange and red pipes flaunt their role in “heat recovery” at Stanford University’s Central Energy Facility. The center for powering the California campus—more than a thousand buildings—the facility was transformed from an aging gas-fired plant to one fueled mostly by an off-site solar farm, fulfilling a goal of carbon neutrality and reducing energy use by a third. With large health care and research buildings, the campus needs as much heating as cooling; now a unique recovery system taps heat created in cooling processes to supply 93 percent of the heating and hot water required for campus buildings. The plant reduces Stanford emissions by 68 percent and potable water usage by 18 percent, potentially saving millions of dollars and one of the state’s scarce resources.

Ng Teng Fong General Hospital

Like other buildings in Singapore, Ng Teng Fong General Hospital incorporates parks, green roofs, and vertical plantings throughout its campus. But the city-state’s hospitals haven’t traditionally offered direct access to fresh air, light, and outdoor views. This hospital marks a dramatic change, optimizing each for patients. About 70 percent of the facility is naturally ventilated and cooled by fans, cross-ventilation, and exterior shading, saving on precious water resources. The building uses 38 percent less energy than a typical hospital in the area.

Eden Hall Farm, Chatham University

After receiving the donation of 388-acre Eden Hall Farm, 20 miles north, Pittsburgh’s Chatham University created a satellite campus centered around a sustainable living experiment. The university views the landscape—an agricultural area adjacent to an urban center—as critical to supporting cities of the future. The original buildings are complemented by new facilities for 250 residential students (and eventually 1,200), including a dormitory, greenhouse, dining commons, and classrooms. Students get hands-on experience in renewable energy systems—the campus generates more than it uses—sustainable agriculture and aquaculture, waste treatment, and water management. Now home to the Falk School of Sustainability, the farm is producing the next generation of environmental stewards, who follow in the footsteps of alum Rachel Carson.

Milken Institute School of Public Health, George Washington University

At George Washington University’s Milken Institute School of Public Health, located in the nation’s capital, design embodies well-being. Built around an atrium that admits light and air, the structure encourages physical activity with a staircase that spans its eight levels. A green roof reduces storm runoff; rainwater is collected and stored for plumbing, resulting in a 41 percent reduction in toilet fixtures’ water use. Limestone panels (left) were salvaged from the previous building on the site. Materials used throughout the building contain recycled content.

National Oceanic and Atmospheric Administration’s Inouye Regional Center

Located at the heart of Pearl Harbor, on Oahu’s Ford Island, the National Oceanic and Atmospheric Administration’s Inouye Regional Center repurposed two airplane hangars—which narrowly escaped destruction in the 1941 attack—linking them with a new steel and glass building (right). The research and office facility for 800 employees was raised to guard it from rising sea levels. Given the size of the hangars, daylight illuminated only a small fraction of the space, so specially crafted lanterns reflect sunlight further into their interiors. Necessity required invention: Due to anti-terrorism regulations, no operable windows were allowed in the space. Through a passive downdraft system that taps prevailing sea breezes, the building is completely naturally ventilated. The adjacent waterfront was returned to a more natural state with native vegetation.

R.W. Kern Center

Serving as the gateway to Hampshire College, in Amherst, Massachusetts, the multipurpose R.W. Kern Center holds classrooms, offices, a café, and gallery space—and is the place where prospective students are introduced to campus. The school converted what was once an oval driveway into a wildflower meadow, now encouraging a pedestrian approach (seen above). The center is self-sustaining, generating its own energy through a rooftop solar array, harvesting its water from rainfall, and processing its own waste. Its gray water treatment system is in a pilot program for the state, and may pave the way for others.

Manhattan 1/2/5 Garage & Salt Shed

Two buildings belonging to New York City’s sanitation department redefine municipal architecture. Resembling a grain of salt, the cubist form of the Spring Street Salt Shed holds 5,000 tons for clearing icy streets. The Manhattan 1/2/5 Garage (background), whose floors are color-coded for each of the three districts, is home to 150 vehicles, wash and repair facilities, and space for 250 workers. The garage is wrapped in 2,600 aluminum “fins,” shading devices that pivot with the sun’s rays, reducing heat gain and glare through the glazed walls while still allowing views to the outside. Municipal steam heats and cools the building, so no fuels are burned. A 1.5-acre green roof reduces heat-island effect and filters rainwater. A condensate by-product of the steam is also captured, and, along with the rainwater, used for toilets and the truck wash. Combined with low-flow fixtures, the process reduced water consumption by 77 percent.

Starbucks Hillsboro, Oregon

Starbucks has been a leader in the development and implementation of a scalable green building program for over a decade .Starbucks joined the U.S. Green Building Council® (USGBC) in 2001 and collaborated with them to develop the LEED® for Retail program, an effort to adapt LEED (Leadership in Energy and Environmental Design) to new construction and commercial interior strategies for retail businesses. In 2008,Starbucks challenged themselves to use LEED certification not just for flagship stores and larger buildings, but for all new, company-operated stores. Many people, even internally, were skeptical, especially with Starbucks growth across the globe. But by collaborating with USGBC and other like-minded organizations, we have been able to integrate green building design not only into new stores but also into our existing store portfolio. Starbucks has also succeeded in providing a practical certification option for retailers of all sizes.

The Edge, Deloitte

The Edge, located in Amsterdam, is a model of sustainability.is billed as the world’s most sustainable office building and has the certification to prove it. But, it’s more than that. The place is, well, fun. And interesting. And inviting. So much so that professionals are actually applying for employment with Deloitte Netherlands because they want to work in the building. That it has become a recruiting tool is a satisfying side effect of a project designed to both redefine efficiency and change the way people work. “We wanted to ensure that our building not only had the right sustainability credentials, but was also a real innovative and inspiring place for our employees,” says Deloitte Netherlands CEO Peter Bommel.

High Performance Building Design

Green-Building

970 Denny, a residential high-rise under construction in South Lake Union, used early energy modeling to demonstrate that efficiency from the water source heat pump system would offset increased thermal loss from expansive glazing.

The Federal EPA has implemented several strategies to enhance sustainability, including:

  • Conducting retro-commissioning and re-commissioning to improve energy performance
  • Using the most efficient heating, ventilation and air conditioning equipment and lighting
  • Assessing for compliance with ventilation and thermal comfort standards
  • Installing renewable energy systems
  • Replacing plumbing fixtures with higher efficiency models
  • Installing advanced energy and water meters
  • Reducing irrigated landscape areas
  • Retrofitting buildings and landscapes with low impact development features
  • Using integrated pest management techniques
  • Contracting green cleaning services
  • Purchasing environmentally preferable materials
  • Implementing materials reduction, reuse, recycling and composting programs

Airtight construction controls the transfer of heat and moisture into and through the building envelope. Thermal bridge-free assemblies avoid the envelope penetrations that sap buildings of energy, comfort, and durability. Continuous insulation keeps heat where it’s wanted. Excellent windows and doors limit heat loss while capturing daylight and passive solar energy. Shading elements shield the building from passive solar gains when unwanted. And a constant supply of filtered fresh air comes in through a balanced heat recovery (or energy recovery) ventilation system that recaptures the thermal energy of exhaust air and keeps it inside the building. “Envelope-first” focus design consideration dramatically reduces the energy demand to heat and cool high-performance building. In fact, Passive House buildings routinely reduce heating and cooling energy by up to 90%.

Green-Building-WorldThe research will further build on the results of the Well Living Lab’s latest study findings, published in Building and Environment. The study found that temperature, noise, and lighting in open office environments affect employees’ ability to get work done. This was a proof-of concept study that demonstrated the strength of living lab methodology in measuring realistic occupant responses to select environmental changes in an open office. Specifically, it indicated that employees are most sensitive to thermal conditions, followed by work-related noise such as conversations and lack of natural light from windows when working in open office environments. These factors affected work environment satisfaction, productivity, and even carried over into the mood of employees and their sleep.
