To support high-performance, cost-effective project outcomes through an early analysis of the interrelationships among systems.
Option 1. Energy- and Water-Related Systems (1 point)
Starting in predesign and continuing throughout the design phases, identify and use opportunities to achieve synergies across disciplines and building systems. Use the analyses described below to inform the owner’s project requirements (OPR
), basis of design
), design documents, and construction documents. Conduct analyses in energy- and water-related systems (1 point).
Choose two of the following to analyze:
Establish an energy performance target no later than the schematic design phase. The target must be established using one of the following metrics:
- kBtu per square foot-year (kWh per square meter-year) of site energy use
- KBtu per square foot-year (kWh per square meter-year) of source energy use
- pounds per square foot-year (Kg per square meter-year) of greenhouse gas emissions
- energy cost per square foot-year (cost per square meter-year)
Perform a preliminary energy analysis before the completion of schematic design that explores how to reduce energy loads for the interior design project and accomplish related sustainability goals by questioning default assumptions and testing options. Assess options associated with each of the following in terms of project and human performance, as applicable:
- Basic envelope attributes. Insulation values, window-to-wall ratios, glazing characteristics, shading, window operability.
- Programmatic and operational parameters. Multifunctioning spaces, operating schedules, space allotment per person, teleworking, reducing building area, ongoing operations and maintenance issues.
- Lighting levels. Interior surface reflectance values and lighting levels in occupied spaces.
- Thermal comfort ranges. Assess thermal comfort range options.
- Plug and process load needs. Reducing plug and process loads through programmatic solutions such as equipment and purchasing policies or layout options.
Perform a preliminary water budget
analysis before the completion of schematic design that explores how to reduce potable water loads, reduce the burden on municipal supply and/or wastewater treatment systems, and accomplish related sustainability goals. Assess and estimate the project’s potential nonpotable water supply sources and water demand volumes, including the following, as applicable:
- Fixture and fitting water demand. Assess flow and flush fixture demand volumes, calculated in accordance with WE Prerequisite Indoor Water Use Reduction.
- Process water demand. Assess kitchen, laundry, cooling tower, and other equipment demand volumes, as applicable.
- Supply sources. Assess all potential nonpotable water supply source volumes, such as on-site rainwater and graywater, municipally supplied nonpotable water, and HVAC equipment condensate. Analyze how nonpotable water supply sources can contribute to the water demand components listed above.
Before site selection, analyze project goals to identify and select the building site or base building
that will provide the most opportunities and fewest barriers for project. Assess at least two potential locations or base building
options, taking into consideration at least the following:
- Building site attributes. Assess the building’s location and site design characteristics.
- Transportation. Assess the tenant occupants’ transportation needs for commuting to and from the site, including convenient access to alternative transportation that meets occupants’ needs.
- Occupant and community well-being. Assess the building’s ability to provide daylight and views, indoor air quality, and other indoor environmental quality characteristics. Identify community assets and the proximity of vulnerable populations surrounding the project. Assess the project’s ability to provide positive social, economic, and environmental benefits for existing community members, as well as any potential negative impacts.
Beginning in pre-design and continuing throughout the design phases, review and then complete the LEED Project Team Checklist for Social Impact in order to assess and select strategies to address issues of inequity within the project and its community, team and supply chain. Through research and consultation with key stakeholders, ensure that all responses within the Checklist are ultimately documented as “Yes” or “No,” and complete all sections for Stakeholders and Goals.
Health & Well-being
Beginning in pre-design and continuing throughout the design phases, use the following steps to inform the design and construction documents:
- Establish health goals. Set clear and specific goals to promote the health of core groups, including:
- Building occupants and users
- Surrounding community
- Supply chain
Develop a statement of health goals for each population, including a summary of how this health goal relates to the highest priority health need for each population.
- Prioritize design strategies. Select specific design and/or programming strategies to address the project’s health goals. This could be accomplished by holding a stand-alone “health charrette” or by integrating health considerations into an existing green charrette.
- Anticipate outcomes. Identify expected impacts on population health behaviors and outcomes associated with the project’s prioritized design strategies
Develop a Project Team Letter. Provide a dated letter on the letterhead of the Integrative Process Facilitator that summarizes the team’s integrative process approach and describes the difference that this integrative approach made in terms of improving project team interaction and project performance.
- Describe the approach developed by the project team for engaging a clearly defined and manageable integrative design process beginning in pre-design and continuing throughout the design phases.
- The letter must include a separate summary for each issue area analyzed by the project team, describing how the analysis informed the design and building form decisions in the project’s OPR and BOD and the eventual design of the project. Describe the most important goals for each issue area and provide clear guidance on how to evaluate the project’s impact on the selected goals.
The creation of this letter should be a team effort facilitated by the Integrative Process Facilitator. The letter must be signed by all principal project team members and made available to key stakeholders including, but not limited to the owner(s), facility manager(s), tenant(s), and community members. Describe how the letter was distributed to these stakeholders and/or made publicly available.
Option 2. LEED Certified Building (1 point)
Select a LEED certified building.
