Ten Sustainability Measures


 
A design competition to recognize student work that displays sustainable design at the highest level.
 
Presented by AIA COTE + ACSA.

 Measure 1: DESIGN & INNOVATION 
Sustainable design is an inherent aspect of design excellence. Projects should express sustainable design concepts and intentions, and take advantage of innovative programming opportunities.

Narrative: Describe how sustainability strategies are incorporated into the overall design strategy. What are the major environmental issues and goals?

May include: 
• Key environmental issues; how and why they became important priorities
• Key ecological goals and concepts for your project and how they shaped your thinking.
• How these goals and concepts were expressed in the design
• Sustainable design innovations
• How sustainability measures led to a better overall project design
• Process of program analysis; resource efficiencies realized by innovative programming
• Efforts to “right size” the project and to reduce unnecessary square footage.

 Measure 2: REGIONAL/COMMUNITY DESIGN 
Sustainable design values the unique cultural and natural character of a given region.

Narrative: How does the design respond to the region where it’s located? How does the design promote regional and community connectivity? What steps are taken to encourage alternative transportation?

May include: 
• How the design relates to the local context and to larger regional issues 
• How the design promotes regional and community connectivity
• How the design promotes a sense of place, public space and community interaction
• How the design educates its users about the environmental strategies it employs
• Efforts to provide for those using transportation alternatives
• Site selection criteria to reduce automobile use
• How mandated parking was reduced

 Measure 3: LAND USE & SITE ECOLOGY 
Sustainable design protects and benefits ecosystems, watersheds, and wildlife habitat in the presence of human development. 

Narrative: How does the development of the site respond to its ecological context? Consider water, air, plants, and animals at different scales.

May include: 
• How the development of the site responds to its ecological context, including the watershed, and air and water quality at different scales from local to regional level
• How the development of the site and buildings contribute to environmental quality 
• How the design accommodates wildlife habitat preservation and creation
• How the design protects or creates on-site ecosystems
• How the design responds to local development density or conditions
• How the design encourages local food networks

 Measure 4: BIOCLIMATIC DESIGN 
Sustainable design conserves resources and maximizes comfort through design adaptations to site-specific and regional climate conditions.

Narrative: Describe how the building reacts to the local climate and site with an emphasis on occupant comfort. Discuss how the building massing and fenestration relates to the sun path and the prevailing winds.

May include:
• Project response to local climate, sun path, prevailing breezes, soil, hydrology, and seasonal and daily cycles through passive design strategies
• Description of internal versus external building loads
• Design strategies that reduce/eliminate the need for non-renewable energy resources
• How these strategies specifically shaped the plan, section, and massing
• How these strategies specifically affected project placement, orientation, and shading
• Integrated pest management considerations

Metric: Percent of the year that occupants will be comfortable using passive systems

 Measure 5:  LIGHT & AIR 
Sustainable design creates comfortable interior environments that provide daylight, views, and fresh air. 

Narrative: Discuss design strategies that relate to daylighting, electric lighting, ventilation, indoor air quality, views, and individual controllability.  

May include: 
• Design strategies for daylighting, task lighting, and views
• Design strategies for ventilation, indoor air quality, and personal control systems
• How the project’s design enhances users’ connectedness to nature
• Design team approach to integration of natural systems and appropriate technology

Graphic: Model photos, drawings or diagrams of daylight and ventilation strategies; test models. 

Metric: Percent of the building that can be daylit (only) during occupied hours; Percent of floor area with views to the outdoors; Percent of floor area within 15 ft. of an operable window.

 Measure 6:  WATER CYCLE 
Sustainable design conserves water and protects and improves water quality. 

Narrative: How does the design manage storm water? How does the design conserve potable water? How is the project innovative in the way that it uses and treats water?

May include: 
• How building and site design strategies manage site water and drainage
• Design strategies that capitalize on renewable water sources (i.e. precipitation) on site
• Water-conserving landscape and building design strategies
• Reuse strategies for water including use of rainwater, graywater, and wastewater

Percent of storm water that is managed onsite: (2 year, 24-hour event. Use supplied spreadsheet to calculate)

 Measure 7:  ENERGY FLOWS & ENERGY FUTURE 
Sustainable design conserves energy and resources and reduces the carbon footprint while improving building performance and comfort. Sustainable design anticipates future energy sources and needs.

Narrative: How does the design seek to decrease the total energy use and carbon footprint of the building? Emphasize strategies to reduce heating and cooling loads, reduce peak electricity demand, reduce plug loads, generate onsite energy, and anticipate future carbon free energy sources.

May include:
• How the design reduces energy loads for heating, cooling, lighting, and water heating
• How the design and integration of building systems contributes to energy conservation and reduced use of fossil fuels, reduces green house gas emissions and other pollution improves building performance and comfort. 
• Use of on-site renewable and alternative energy systems. 
• Anticipation of future and carbon neutral fuel sources
• Strategies to reduce peak electrical demand. 
• How the design remains functional during power outages or interruptions in fuel supply

Metric:
Total EUI: (build a simple energy model to calculate EUI using eQuest, Sefeira, Autodesk® Green Building Studio, or another energy modeling program);  Energy generation (if any) in kWh/yr: (use
PVWatts® Calculator or solar-estimate.org for solar or wind);  Net EUI (with renewables if applicable)

 Measure 8:  MATERIALS & CONSTRUCTION
