After you have reduced your parking hardscape as much as possible through reduced parking spaces, stacked parking, minimizing sidewalks, and other strategies, try the following steps to reduce heat island effect even further.
Define your project’s LEED boundary, and ensure that it is consistent across all credits pursued by your project. The LEED boundary defines the scope of work, and must include any land that will be disturbed and or used by your project.
Examine existing conditions to help guide site plan development. Does your existing site have shading from trees, covered parking, or light-colored hardscape? Are there ways to minimize your project site’s hardscape and parking areas (including gravel, which is considered hardscape)?
Average the overall scores of the auditors to come up with a final score for the entire building. The sample size of audited space is in proportion to a space type’s prominence in the building, therefore no further normalizing based on square footage is necessary.
After randomly selecting the spaces to audit, print out the same number of forms as rooms, and fill out a form for each space type. (See instructions in the Documentation Toolkit.)
