The Lawrence Berkeley National Lab (LBNL) is conducting a study to explore the efficiency of hot water distribution systems in California residences, "Reducing Waste in Residential Hot Water Distribution Systems." 

We are looking for volunteers to take part in this study --

You’ve likely had the experience of waiting for shower water to get hot? Until the shower reaches a comfortable temperature, the water goes down the drain. Both water and energy could be saved! Information about hot water and natural gas use in homes will enable the development of effective conservation strategies for both energy and water.  

To be eligible to take part in this study, you must be at least 18 years of age, live in a Bay Area or Sacramento Area home that you own with a single residential water heater, speak English in your home, and have internet access over which the monitoring system can transmit data. 

If you are interested in participating, submit the web form by 01.31.14: https://www.surveymonkey.com/s/LBNLHotWaterStudyParticipants will receive $50 at the beginning of the study after meters are installed and an additional $50 after monitoring is completed and equipment has been removed. Please note that LBNL employees are not eligible to receive incentive.
