Project Status

Efforts to Date

We have already prepared an extensive literature review of 469 readily available documents related to residential commissioning. The body of the report first discusses the status of commercial building commissioning and compares it with residential commissioning. It then summarizes existing metrics, diagnostics, and norms that are relevant for evaluating, tuning, and retrofitting various aspects of new and existing houses. In the report’s appendices, an annotated bibliography describes the relevance of each document. Annotations are grouped together by performance areas of concern. All 469 documents are also listed together in alphabetic order.

There is a substantial amount of useful information in the literature relevant to residential commissioning. However, as described in the literature review, there are also some significant gaps in the existing knowledge that require further research and development. Areas in particular need of work include:

metrics, diagnostics, and norms for thermal mass and moisture-damage susceptibility;

diagnostics for steady-state capacity and efficiency, as well as refrigerant charge level, for cooling equipment and heat pumps;

diagnostics and norms for ventilation effectiveness and efficiency;

diagnostics to evaluate the potential for backdrafting and combustion gas spillage; and

metrics, diagnostics, and norms for controls and other electrical appliances.

View the body of the report as a .pdf document.

Download the appendices in Microsoft Word 2000 format. This format was used because the document contains numerous hyperlinks which could not be preserved in the conversion to .pdf format. You will not be able to view the hyperlinks in Microsoft Word '97 or earlier versions of Word.

If needed, you can download a Word 2003 viewer from Microsoft, or Adobe Acrobat (.pdf viewer).

Next Steps

In the next step of the project, a set of metrics, diagnostics, and norms for residential commissioning will be developed based on analyses of data from the literature review. Subsequent field tests of selected commissioning elements will demonstrate the accuracy, usability, relative importance, and value of each element for both new and existing California houses. Finally, guidelines for the building industry will be developed to describe the commissioning procedures. Research findings will also be transferred to the building industry through workshops and presentations.
