Outcome-Based Performance

Measuring buildings based on performance outcomes is an emerging trend in high performance buildings that allows owners and operators to understand operational energy demands in addition to design intention. NBI studies and market research are on the leading edge of performance based outcomes.

Deep Energy Retrofits

Deep energy retrofits offer a chance to make the 99% of buildings that are already built energy efficient. NBI research examines holistic approaches to renovation that integrate lighting, mechanical, envelope, plug loads and other energy loads to transform existing buildings into "new" high performance projects.
