In 2018 the RTF mounted a concerted effort to increase emphasis on whole building energy efficiency. As energy efficiency programs seek deeper savings, they are exploring approaches that focus on the energy use of the building as a whole, rather than taking an end use by end use approach. In January 2018, the RTF discussed the results of a scoping exercise during which regional stakeholders were interviewed regarding their needs in the whole building energy efficiency space. This project also compared existing national guidance documents on estimating savings from a whole building approach to understand what is currently being addressed. Through this effort, the RTF identified some gaps in these existing guidance documents, particularly around estimating the costs and lifetimes of whole building program approaches. The RTF directed staff to continue to explore this space, focusing on areas lacking guidance and engaging in other efforts to provide clarity where needed.

Latest Effort

In May 2019 the RTF adopted a white paper surveying the reliability of savings estimates based on data-driven models of commercial building-level energy consumption.  This process built on the work started last year and was brought through the Whole Building Subcommittee prior to being seen by the RTF. This paper summarizes the current state of knowledge regarding reliability of savings estimates based on data-driven models of commercial building-level energy consumption. Findings and recommendations presented in the Executive Summary were formally endorsed by the RTF on May 21, 2019. The paper is intended to support current and future efforts to set research priorities and develop guidance where needed. Presentations from both meetings are linked below as well as the final approved white paper.

As a first step in exploring this whole building effort, the RTF contract analysts started to explore the value that models have in estimating energy savings for whole buildings, with a focus on what aspects of those models require greater scrutiny going forward. The following are materials produced from those efforts:
