Building Energy Modeling for Owners and Managers: A Guide to Specifying and Securing Services

Building Energy Modeling for Owners and Managers: A Guide to Specifying and Securing Services was developed to help owners and managers define and procure modeling services in commercial new construction, renovation, or operation improvement projects. The topics and examples focus on issues relevant to the owner, including the value of…


Kickstarting the Widespread Adoption of Automotive Carbon Fiber Composites: Key Findings and Next Steps

This report details the results of RMI’s 2012 Autocomposites Workshop. During the course of a three-day workshop, ~40 leading experts from across the automotive carbon fiber composite value chain, industry experts, and government representatives convened to develop approaches to break down the barriers that have stifled advancements in vehicle weight…


Who Needs Skeletons? We’ve got Servers in the Closets.

IT Industry analysts estimate there are over 11 million servers in use in 2012, growing to almost 13 million by 2020. While many large data centers are addressing energy use, half of the energy consumption for U.S. data centers comes from small server rooms and closets. These server rooms are…


Making Big Cuts in Data Center Energy Use

The energy used by our nation’s servers and data centers is significant. the Environmental Protection Agency estimated that this sector consumed about 61 billion kilowatt-hours (kWh), accounting for 1.5 percent of total U.S. electricity consumption. So how much room for improvement is there?

Collaborate and Capitalize: Post-Report from the BEM Innovation Summit

In 2011, RMI convened an invited group of key stakeholders within the building energy modeling (BEM) community to increase collaboration and develop implementation plans to address key barriers. This report describes the motivation for convening the BEM Innovation Summit; provides a recap of the group events and discussions; provides a…


Life Cycle Cost Analysis: Is it Worth the Effort?

Life cycle cost analysis (LCCA) is often considered important for both new and retrofit building construction projects but is rarely implemented, often because it is perceived to be “not worth the effort.” This paper addresses the question of whether an LCCA is worth the effort and shows that an LCCA…


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…
