Project Info COMPLETE Project Title Hotel Guest Room Energy Controls Project Number SDGE-2007/8-02 Investor Owned Utilities SDG&E End-use HVAC Sector Public, Commercial Project Year(s) 2007 - 2008

Project Summary

Hotel guest room energy management control systems are widely used throughout the world, but currently have limited acceptance in the United States.  An increased market penetration of such systems could significantly reduce hotel energy use.

The objective of this study is to quantify annual energy savings for occupancy controlled guest room thermostats in San Diego climate zones. SDG&E® will evaluate the results of this project to determine feasibility of developing a fixed incentive amount for the technology. The California Energy Commission (CEC) is considering incorporating the technology in the Codes and Standards base for the entire California hotel industry. The results from this study will be utilized in the statewide Codes and Standards Enhancement (CASE) study undertaken by SDG&E® and SoCalGas for setting building standards in the 2011 revision of California Title 24 Code Revision, Section 121(c). A secondary objective is to study the potential savings that could be achieved with lighting controls in guest rooms.
