2009 Assessment CALL FOR DATA

August 21, 2007

Dear Colleague:

With sponsorship from the California Energy Commission's Public Interest Energy Research (PIER) program--and in cooperation with the California Commissioning Collaborative--Lawrence Berkeley National Laboratory (LBNL) is expanding the world's largest database of commissioning and retro-commissioning cost-benefit case studies. This new round of data collection builds on a major study originally published in 2004, which has helped the commissioning community make the business case for this emerging energy management service. While the 2004 study included only U.S. examples, projects from anywhere in the world are now welcome.

We invite you to submit your project(s) for inclusion in the database. You can do so either by inputting data into our easy-to-use Excel template, or by furnishing "raw" information to help us complete the template (e.g. existing papers or reports on your commissioning project or projects). Submissions will be accepted until October 31, 2007, with the possibility of extension by arrangement.

To initiate your participation and download the template, please answer the three questions on this page:

In exchange for your participation, if you enter your data into the Excel template, you will receive a personalized benchmarking analysis of how your project(s) compare to the entire sample in terms of energy savings, cost-effectiveness, and a number of other metrics (depending on how much data is provided). You will also receive priority processing, a preview draft of the results, and have the option of receiving public recognition in the report, although your project(s) can remain anonymous if preferred.

While we are able to accommodate a large amount of detail on a given project (which, of course, increases the depth of the analysis we can perform), the minimum substantive data requirements are quite simple, as follows:

1. Location of project (state and country)

2. Type of building(s)

3. Floor area

4. Total costs and dates of commissioning or retro-commissioning

5. Weather-normalized energy savings associated with verified measures (net of any savings associated with non-commissioning retrofits)

We hope that you will participate in the study.
