LEED ID - Innovation and Design
Innovation and Design points encourages implementing strategies not address in the typical LEED for Homes rating system
The Innovation and Design process encourages the project team to improve the requirements of the current LEED for home rating system by earning points in innovative design ideas, exemplary performance or regional best practices that can be shown to improve environmental and health benefits to the homes' occupants and workers.
Green homebuilding strategies and techniques are most effectively implemented as part of an integrated design process, with input from individuals involved in each phase of the project. Good design can keep costs down and ensure proper integration of green techniques and achievement of project goals.

- Final Design
- Construction
Monthly meeting with project team to review status, goals, problems and next steps.
At least one principal member of the project team shall be a professional who is credentialed with aspect to LEED for Homes as determined by the U.S. Green Building Council.
No later than the Design Development phase and preferably during Schematic Design, conduct at least one full-day integrated design workshop with the project team defined in ID 1.2. Use the workshop to integrate green strategies across all aspects of the building design, drawing on the experience of all participants.
Green experts agree that the most successful green projects are those where the experts collaborate early in the design process. Even conventional designs can greatly benefit from the integrated project planning that is set forth below and is encourage by the LEED for Homes program. These credit are intended to encourage project integration and collaborate between project team members as early as possible in the process.
- Initiate integrated project planning and integrated design as early as possible
-
During the preliminary rating, set specific goals for the project, including certification goals
- Once goals have been set, earn approximately 5 points about the goal threshold
- The integrated team may include members outside the list provided in LEED ID 1.2
- With approval of Provider and Green Rater, a project team may conduct multiple 1/2 day charrettes

Design a home meeting the following requirements:
- N/S facing glazing 50%> E/W Glazing
- E/W axis of building is within 15 degrees of due E/W
- Roof > 450 s.f. south-facing area
- >90% south-facing glass is shaded
Successful solar design for a new home is paramount on the siting and orientation of the new home. It is essential that all passive and active systems are analyzed during or prior to home placement. Plan orientation, window placements, roof shapes and orientation to the sun, shading designs and cooling opportunities for the natural ventilation.
Choose site location and orientation as soon as possible in the design process.
Where possible and appropriate, plant deciduous trees for shading in the summer, but allowing sun to penetrate in the winter months, when the leaves are shed off the trees.
Investigate shading by overhand analysis, vegetation or window blinds.
Projects planning to adopt additional passive solar design elements should use the performance pathway in the LEED Energy and Atmosphere category. Optimal passive solar techniques vary based on the location, climate, and specific design of the home.
Investigate Energy Modeling for it's critical feedback in the analysis phase of a project.
Four Calculations are required for this credit:
Calculate the ratio of glazing area on the north and south-facing walls to the glazing area on the east and west-facing walls.
Calculate the precise orientation of the home. Using a compass, detailed map, GIS calculations, or an alternative method, demonstrate that the east-west axis of the building is within 15 degrees of due east-west.
Calculate the area of the roof that is south facing. Flat roof area can be included in this calculation.
Provide simulation date on calculations to demonstrate that at least 90% of all south-facing glazing area is unshaded at noon on December 21 and completely shaded at noon on June 21. Information about tools for conducting this calculation can be found under the Resources area below.
None
Builder/Project Team: Present any calculations or simulation results to the Green Rater.
Green Rater: Visually verify that calculations or simulations were performed to meet the credit requirements.
This credit is intended to promote an integrated, system-oriented approach to green project design and development. The selected green home-building strategies and technologies in the Rating System should each be fully integrated into a home's design.
Promote durability and high performance of the building enclosure and its components and systems through appropriate design, materials selection, and construction practices.
Note: USGBC and its representatives are responsible only for verifying the completion of LEED for Homes requirements; such verification in no way constitutes a warranty as to the appropriateness of the selected durability measures or the quality of implementation.
-
Complete the Durability Risk Evaluation Form to identify all moderate and high-risk durability issues for the building enclosure.
- Develop specific measure to respond to those issues
-
Identify and Incorporate applicable Indoor Moisture Control measures in the Moisture Control Measures Table.
Hover HERE for Indoor Moisture Control Measures Table
-
Incorporate above requirements in Contract Documents (drawings, specifications, and/or scope of work).
-
List all the durability measures and indicate their locations in the project documents in a durability inspection checklist. Include the checklist in project documents for use in verification.
During construction, the builder shall have a quality management process in place to ensure installation of the durability measures. This prerequisite can be satisfied by having the builder inspect and check off each measure in the durability inspection checklist.
Have the Green Rater inspect and verify each measure listed in the durability inspection checklist created for 2.1
No matter what the age of the structure, all homes will suffer from moisture damage of some sort, whether for storm damage, water infiltration, or condensation. Builders who address these durability issues will have much less failure rate resulting in less call-back issues and homes lasting much longer between maintenance cycles. This credit emphasizes four basic elements of designing for durability:
- Evaluate the durability risks for a specific home in a specific site.
- Incorporate strategies into the home design to counteract the greatest long-term durability risks
- Have a third party inspect the home to verify that design strategies for durability have been implemented during construction.
Even though these guidelines are followed, it does not guarantee a high-quality home, nor does it guarantee that failures or call-backs will not occur. This section is designed to give builders specific durability guidelines to follow at accesses the highest risk issues.
Durability management is designed to ensure that the highest risk durability issues for any home are addressed and it is important that these issues are addressed as early on in the design process as possible. If the design charrette is held as listed in LEED ID 1.3, address durability issues during that meeting. Complete and submit a Durability Evaluation Form. Seek assistance from consultants as early as possible. Rank each durability as low, medium or high.
Principal Durability Risks:
- Exterior Water
- Interior Moisture Loads
- Air Infiltration
- Interstitial Condensation
- Heat Loss
- Ultraviolet Radiation
- Pests
- Natural Disasters
Once the evaluation has been completed, develop a list of measures and strategies to address the greatest durability risks. Include the risks indicated in the Indoor Moisture Control Measures Table.
Hover HERE for Indoor Moisture Control Measures Table.
Use the list of strategies as a checklist to facilitate inspections, and incorporate each strategy into project documents. A template version of the durability inspection checklist is available from your Provider. If a project team chooses not to use the template, include the following elements into the durability checklist:
- A signed and dated declaration that the builder has evaluated the project's durability risks, incorporated appropriate measures into the design, and inspected to verify that the durability measures were installed or implemented appropriately.
- Basic information about the project, including site address, builder's name and the third-party verifier to indicate that each measure was inspected and verified.
Because more builders are instituting their own quality management and risk management plans, they are assuring quality assurance through consistent performance across a company's operations, and emphasize in-field compliance with drawings, specifications and/or scopes of work. If the builder chooses not to use the quality management plan LEED ID 2.2, these requirements can be satisfied by the builders internal checklist system.
Third party verification of the durability measure is an optional credit. This verification should be conducted by the Green Rater and should consist of inspections and observations of each measure on the durability inspection checklist.

Builder/Project Team: LEED ID 2.1: Complete and submit the Durability Evaluation Form to the Green Rater. Include durability measures in project documents. Develop and submit a completed durability inspection checklist. LEED ID 2.2: Present documentation of quality management processes to the Green Rater or conduct an inspection of durability measures in the home and indicate the completion of the inspection on the durability inspection checklist.
Green Rater: LEED ID 2.1: Verify completion of the Durability Evaluation Form and durability inspection checklist. LEED ID 2.2: Visually verify documentation of quality management process or verify that the project team conducted onsite inspection of durability measures and indicated its completion on the durability inspection checklist. LEED ID 2.3: Visually verify that strategies listed on the durability inspection checklist were incorporated into the home. Upon verification, check off and sign the durability inspection checklist.
Many of the Credits in the LEED for Homes Rating System can serve as durability strategies and may be used in the creation of a durability inspection checklist. If this is done, the home can still receive LEED points for those credits.
