Intent

To support high-performance, cost-effective project outcomes through an early analysis of the interrelationships among systems.

Requirements

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 (BOD), design documents, and construction documents. Conduct analyses in energy- and water-related systems (1 point).

Discovery:
Energy-Related Systems

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.
Water-Related Systems

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.
Implementation:

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.

AND/OR

Option 2. LEED Certified Building (1 point)

Select a LEED certified building.

What does it cost?

Cost estimates for this credit

On each BD+C v4 credit, LEEDuser offers the wisdom of a team of architects, engineers, cost estimators, and LEED experts with hundreds of LEED projects between then. They analyzed the sustainable design strategies associated with each LEED credit, but also to assign actual costs to those strategies.

Our tab contains overall cost guidance, notes on what “soft costs” to expect, and a strategy-by-strategy breakdown of what to consider and what it might cost, in percentage premiums, actual costs, or both.

This information is also available in a full PDF download in The Cost of LEED v4 report.
