Within this guide, you can learn about dimensions of Building Performance and Indoor Environmental Quality (IEQ). While performance is usually evaluated in terms of energy and water used, it should also be evaluated in terms of the indoor environmental conditions that are delivered and the satisfaction of space-users.
Why each dimension is important, how it can be measured, assessed, and improved are discussed for each topic. Links are provided to fuller treatments of many methods. Many of the methods are used in building rating systems such as the EnergyStar Portfolio Manager (for energy benchmarking) and LEED Existing Building Operations and Maintenance (EBOM). Desirable indoor environmental conditions represent a relatively small range of outcomes but the mix of strategies, technologies, and practices for how to get there will vary from building to building and from situation to situation.
Start with establishing these baseline conditions. Doing so is a key step in initiating any systematic improvement process. You want to be able to document where you started and what you have accomplished.
