NREL has this cool database (that needs populating!!).
It’s called the Technology Performance Exchange. You sign in as a user or a contributor, and you have access to performance data for 17 different types of technologies, from lamp ballasts to inverters, with more categories to come.
If you’re a user, you get to search through and compare energy performance data on up to 4 different products in the category, allowing you to evaluate energy and cost savings in energy simulations. Manufacturers, third party verifiers and ‘contributing evaluators’ are allowed to populate the database.
It’s a little spotty now, in terms of data available in all categories, but my quick wheel through it showed up a very well-populated PV category: 10,780 entries. I was able to narrow the search results by system or module, then by module efficiency, rated power, cell material, total # of cells, nominal operating temp and three different performance coefficients.
Other categories, like ‘boilers’ have lots of placeholder entries (ie, brand, product line and model numbers), but have yet to be fully populated with performance data.
This is a big project, and will be über-useful when more completely populated. Spread the word!

Survey @ Low Energy Housing Technology Costs
I’m working with the Net-Zero Energy Home Coalition to deliver a survey for Natural Resources Canada. The aim of the survey is to get a better sense of cost-effective design and construction of Low Energy Houses (near NZE, NZE-ready, NZE, any program or standard that you are involved in). Survey is open until midnight, 14 March 2014.
The survey is best filled out by the person who is most familiar with costing the projects.
Here’s the official invite:
The Net-Zero Energy Coalition is seeking costing information from builders across North America who have direct experience building net-zero energy (NZE), net-zero energy ready (NZEr), or near net-zero energy (nNZE) homes. The Coalition is collecting this data in partnership with Natural Resources Canada.
Your participation will help to validate cost effective design and construction of NZE / NZEr / nNZE homes and support the development of guidelines for building these homes.
Individual responses will be kept anonymous – results of the survey will only be communicated in summary form. Participants will receive a copy of the summary report.
This survey will be open until midnight (Eastern Time) on Friday, March 14th. You can access the survey here.
