About

Efficient Window Coverings was developed by Lawrence Berkeley National Laboratory (LBNL) Windows and Daylighting group in partnership with BuildingGreen, Inc. The site is currently being supported by the US Department of Energy, its Office of Energy Efficiency and Renewable Energy (EERE) and the Building Technologies program. A public-private partnership organization, The Efficient Window Coverings Collaborative, is currently under development and likely to play a significant role in this website over time.

This work is in part guided and supported by the project’s Advisory Committee members:

The LBNL project team:

  • Charlie Curcija
  • Howdy Goudey
  • Robert Hart
  • Christian Kohler
  • Steve Selkowitz

The Building Green project team:

  • Nadav Malin
  • Amie Walter
  • Alex Wilson
  • Peter Yost

The lead web developer for this site was Andrew Waegel of GeoPraxis, Inc. Web design was by Bryan Kring, Kring Design Studio.

This site is dedicated to Dariush Arasteh for his lifetime of work in the field of energy efficiency.

HOW THE WEB SELECTION TOOL WORKS: The web selection tool uses a master table (multi-sheet Excel file) of window covering options and attributes with the range  of values and cell values worked out in a consensus process with the project team and committee. These values are then adjusted for factors such as climate. For each adjustable window covering, the assumption was made that the specific window covering was optimally deployed (since they CAN be adjusted). Conversely, fixed window coverings results were adjusted slightly upwards because they do not NEED to be adjusted.

NOTE: This site was launched in June 2013 with the focus on the qualitative selection tool (Help Me Choose and Compare). LBNL and BuildingGreen are hard at work to add a quantiative module to the selection tool, one that will allow users to compare the thermal performance of window coverings and attachments. This added functionality is slated for 2014.
