Commercial Building Toplighting: Energy Saving Potential and Potential Paths Forward

This report documents the energy-saving potential of toplighting, a form of daylighting that combines skylights and electric lighting controls.

Advanced Controls for Commercial Buildings: Barriers and Energy Savings Potential

Commercial buildings consume just over 17 quads of primary energy per year, about 17 percent of U.S. energy consumption. TIAX has carried out a two-phase study for the U.S. Department of Energy Building Technology Program (DOE/BT) that evaluates the energy saving potential of four advanced controls approaches in commercial buildings. This article presents the key results of the study, namely assessments of energy saving potential and barriers to achieving significant market share for four controls approaches evaluated.
