Paper
Executive Summary  The verdict is in. The research community has identified electrification as a key strategy to decarbonize the economy. Two fundamentally powerful trends contribute to this new opportunity. First, the electric supply mix continues to experience an increased penetration of natural gas, wind and solar, which is rapidly reducing the electric power sector’s emissions rate. Second, existing and new electric powered equipment are increasingly exhibiting higher efficiency levels and lower lifetime costs than their fossil fuel powered counterparts. More
Report
Commissioning and retro-commissioning (RCx) are critical in propelling building performance—but what happens once retro-commissioning is complete? Do the energy savings continue long after installation? And why do some buildings see long-lasting results, while others don't? We set off to answer these questions and more through a comprehensive study of the persistence of energy savings.  More

Report
We studied the viability of performance-based procurement (PBP) to achieve higher energy savings, without increasing capital cost to owners, through early owner involvement, goal setting and energy modeling. The study also examined the role that conservation improvement programs (CIPs) could play in supporting this approach. We tested the PBP method in six pilot projects and observed the outcomes. We supplemented our study with assessment of existing programs, interviews and analysis through the Sustainable Buildings 2030 program, and outreach to energy modeling professionals. More

Report
RTUs are used in more than one third of U.S. commercial buildings, the highest of any cooling equipment type. Why? They are reliable and have a low capital cost, as well as established service and distribution networks. There is anecdotal evidence, however, that these systems operate inefficiently. To validate or refute this evidence, we conducted a multi-level field study sponsored by Minnesota Department of Commerce, Division of Energy Resources. More
