This is exciting news, as water heaters had not been Energy Star certified prior to this, and it will help people make informed decisions about products' energy efficiency and potential long-term cost savings. Depending on the type of water heater, choosing an Energy Star model is estimated to save 7.3 to 55% of typical annual energy use for water heating. This relates to $26 to $277 a year. ]]> http://blogs.hgtvpro.com/hgtvpro/building_science/archive/2008/04/energy_star_water_heating.html http://blogs.hgtvpro.com/hgtvpro/building_science/archive/2008/04/energy_star_water_heating.html DHW Efficiency Gas HeatPump Solar WaterHeating Wed, 09 Apr 2008 11:45:22 -0500 ORNL) have been doing with Habitat for Humanity in Tennessee. ]]> http://blogs.hgtvpro.com/hgtvpro/building_science/archive/2008/03/ornl_and_habitat_for_humanity.html http://blogs.hgtvpro.com/hgtvpro/building_science/archive/2008/03/ornl_and_habitat_for_humanity.html BuildingScience Efficiency SmallHouses Solar Thu, 27 Mar 2008 13:45:55 -0500 A high-performance house client from a few years back just sent me an email saying he has opened a retail store for environmental and sustainable products. He asked me if I could point him toward some products for homeowners to monitor their electrical usage. I figured I'd share the list as an easy entry for a Friday afternoon. :) http://blogs.hgtvpro.com/hgtvpro/building_science/archive/2008/03/inexpensive_home_electrical_en.html http://blogs.hgtvpro.com/hgtvpro/building_science/archive/2008/03/inexpensive_home_electrical_en.html Electrical Feedback MiscElectrLoads Monitoring Fri, 21 Mar 2008 16:36:06 -0500 ABI Research says that the market for home automation and security systems is beginning to open up. Costs of systems and components are coming down, and the technologies are becoming much more accessible to the non-techie. Are we going to see advances in energy efficiency due to the control such systems may have over the HVAC, lighting, and other electric loads? Or, will it be adding electrical consumption to the house where there currently isn't?]]> http://blogs.hgtvpro.com/hgtvpro/building_science/archive/2008/03/is_home_automation_part_of_the.html http://blogs.hgtvpro.com/hgtvpro/building_science/archive/2008/03/is_home_automation_part_of_the.html Automation Controls Mon, 17 Mar 2008 11:55:21 -0500 colleague's paper recently presented at the Buildings X Conference.

January has screamed by somehow. I spent most of the past two months on the road, but am back in the office and excited to share some of the things I've learned at the conferences I've been to. http://blogs.hgtvpro.com/hgtvpro/building_science/archive/2008/01/howd_it_get_to_be_the_end_of_j.html http://blogs.hgtvpro.com/hgtvpro/building_science/archive/2008/01/howd_it_get_to_be_the_end_of_j.html ASHRAE Conference Tue, 29 Jan 2008 14:46:23 -0500 All right, there has been a great response to the post asking what you all thought about thermostats. Thanks to everyone who contributed. There is a lot of good information in your comments. It's funny how we use the term thermostat, like it's an easily defined product that simply controls temperature. However, the variation in experiences indicates it's not so simple. The comments show that it is hard to talk about one component without bringing other components of the house into the conversation. http://blogs.hgtvpro.com/hgtvpro/building_science/archive/2007/12/responding_to_your_thermostat.html http://blogs.hgtvpro.com/hgtvpro/building_science/archive/2007/12/responding_to_your_thermostat.html HVAC Thermostat Sun, 02 Dec 2007 21:58:37 -0500 Energy & Environmental Building Association (EEBA). It was a fun event with a spectacular mix of great folks: builders, home energy experts, product manufacturers, building scientists, utilities, nonprofits, and people who are simply interested in green building.

I've said before that I'd like to have this blog be a bit of collaboration, instead of me just whistling into the Internet. So, I'd like to tap into your brains and lives for some perspective. http://blogs.hgtvpro.com/hgtvpro/building_science/archive/2007/10/is_a_thermostat_just_a_box_on.html http://blogs.hgtvpro.com/hgtvpro/building_science/archive/2007/10/is_a_thermostat_just_a_box_on.html HVAC Thermostat Wed, 31 Oct 2007 11:33:01 -0500 I had the opportunity to work with one of the teams for the 2007 Solar Decathlon competition that recently took place in Washington, D.C.
