Retrofit Industry Needs Assessment Study

The Retrofit Industry Needs Assessment Study is a part of RMI’s RetroFit Depot. Over the next 3–5 years, the RMI RetroFit team will create and execute new approaches to accelerating deep retrofits in commercial buildings. The project aims to retrofit at least 500 buildings within three years and stimulate far…

Whole-Building Retrofits: A Gateway to Climate Stabilization

This paper discusses creative elements of deep whole-building retrofits. It discusses process and technique, how to select suitable buildings, the key players that must be involved, project development tasks the design team must complete, and tools and skills that engineers will need to acquire to comprehensively and cost-effectively retrofit the…

Achieving Radically Energy Efficient Retrofits: The Empire State Building Example

In order to avoid reaching unsustainable levels of atmospheric greenhouse gas (GHG) concentrations, we must reduce GHG emissions by 75% by 2050. “Deep” commercial building retrofits are an essential part of the solution. A “deep” retrofit is (1) a package of integrated, whole-building energy efficiency measures that (2) is coordinated…

Pulling the Levers on Existing Buildings: A Simple Method for Calibrating Hourly Energy Models

Comprehensive building retrofits require an investment grade audit in conjunction with a calibrated hourly energy model. Even with the most thorough audit processes, uncertainty still remains when identifying and modeling building parameters. This uncertainty propagates throughout the final calibrated model and affects the quality of the energy saving estimates. This…

Energy Modeling at Each Design Phase: Strategies to Minimize Design Energy Use

Design teams often use energy modeling as an accounting or code compliance tool to establish that minimum requirements are met. Used in this way, significant opportunities to inform and improve building design are overlooked. Properly used, energy modeling can provide outputs that optimize a building’s energy consumption, reduce life cycle…
