To document this credit you'll need a floor plan and elevation identifyng the structural components that are retained and those that are demolished. It verifies the accuracy of elements included in the building reuse calculations.

These sample narrative and plans for corrective action provide references as you develop your own narrative and plan for this credit. The corrective action plan guidance document provides a set of questions to consider in developing your project building's plan.

A floor plan like this project example is required to document the presence of entryway track-off systems, length and location. Note that this sample shows six-foot entryway systems because the project predated LEED 2009. For LEED 2009, the systems need to be ten feet in length.

The climate zones shown on this Department of Energy map are relevant to all options for this credit.

This graph, for an office building design, shows how five overall strategies were implemented to realize energy savings of 30% below an ASHRAE baseline. (From modeling conducted by Synergy Engineering, PLLC.)

Option 1 calculates savings in annual energy cost, but utility prices may vary over the course of a year. This sample demonstrates how to document varying electricity tariffs.

Carefully research products and examine cut sheets to find fixtures and fittings meeting the credit requirements, as shown in these examples.
