The measuredenergy savings resultingfrom using night temperaturesetback in typical lightconstructionwooden office buildingswas determined. Researchersinstalled monitoringequipmentin a six-building sample of two-story wooden buildingsat Fort Devens, Massachusetts. Data obtained duringboth single-setting and night-setbackoperating modes were u._edto develop models of each building's heat consumptionas a functionof the differencebetween inside and out_ide temperature. These models were used to estimate seasonal savings that could be obtained from the use of nightsetback thermostatcontrol. The measured savings in heating energy from using night temperaturesetback for the six Fort Devens buildings ranged from 14% to 25%; the mean savings was 19.2%. Based on an energy cost of $0.65/therm of naturalgas, the estimated average cost savingsof using automaticsetback thermostatsin these buildings is $780 per year per building. The authorswould like to thank Bobby Orr and his staff at the Fort Devens Directorate of Engineeringand Housing for.their support in installingthe automaticsetbackthermostats. Appreciationis extendedto PNL staff whose efforts supported the study: John Schmelzer for monitoringequipmentpreparationand installation, Su Thelen for remotedata collection, and Andrea Wood for data analysis. Thanks go also to ShannonMcDaniel, ShannonElectric, for installationof monitoringequipment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
