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?
• 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
Metric: 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.
• 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
Sustainable design includes the informed selection of materials and products to reduce product-cycle environmental impacts, improve performance, and optimize occupant health and comfort.
Narrative: Describe the project’s material selection criteria, considerations and constraints. What efforts were made to reduce the amount of material waste and the environmental impact of materials over their lifetime? Discuss specific materials used.
• Efforts to reduce the amount of material used on the project.
• Materials selection criteria, considerations, and constraints for: optimizing health, durability, maintenance, and energy use reducing the impacts of extraction, manufacturing, and transportation
• Enclosure performance in relation to air, moisture, water and thermal characteristics
• Consideration of life cycle impacts and results of life cycle assessment if available
• Construction waste reduction plans; strategies to promote recycling during occupancy
Graphic: Wall section of the building envelope design and either a hygro-thermal analysis or life cycle assessment.
Measure 9: LONG LIFE , LOOSE FIT
Sustainable design seeks to enhance and increase ecological, social, and economic values over time.
Narrative: Describe how the design promotes long-term flexibility, adaptability, and resilience.
• How the project was designed to promote long-term flexibility and adaptability
• Anticipated project service life; description of components designed for disassembly
• Materials, systems, and design solutions developed to enhance versatility, durability, and adaptive reuse potential
• How the project anticipates and celebrates weathering over time
Measure 10: COLLECTIVE WISDOM & FEEDBACK LOOPS
Sustainable design strategies and best practices evolve over time through documented performance and shared knowledge of lessons learned.
Narrative: What steps would you take to ensure that the building performs the way that it is designed? What lessons have you learned from this project that you will apply to the next project? What lessons have you learned from past projects that were applied to this project?
• Modeling and evaluation of the design during the programming and design phases
• Collaborative efforts between design team, consultants, client, and community
• Lessons learned during the design of the building
• How these lessons would change your approach to this project or future projects
• A question that would be investigated in a post-occupancy evaluation of this project.
