Optimize energy performance

Intent

Achieve increasing levels of energy performance above the prerequisite standard to reduce environmental impacts associated with excessive energy use.

Requirements

Reduce design energy cost compared to the energy cost budget for regulated energy components described in the requirements of ASHRAE/IESNA Standard 90.1-1999, as demonstrated by a whole building simulation using the Energy Cost Budget Method described in Section 11:

Regulated energy components include HVAC systems, building envelope, service hot water systems, lighting and other regulated systems as defined by ASHRAE.

Credit 1.1 (2 points) Reduce design energy cost by 20% / 10%.
Credit 1.2 (4 points) Reduce design energy cost by 30% / 20%.
Credit 1.3 (6 points) Reduce design energy cost by 40% / 30%.
Credit 1.4 (8 points) Reduce design energy cost by 50% / 40%.
Credit 1.5 (10 points) Reduce design energy cost by 60% / 50%.
