Both these housing units are heated with oil-fired Burnham boilers. Notes: For programmable thermostats in teacher housing units we work with local maintenance staff. Our goal is to generally set thermostats to a night time set-back of 62 - 64 degrees and a daytime / evening / weekend temp of 68-70 degrees. If occupants are interested and willing to go beyond that, maintenance staff work with them to program the thermostat to 62 degrees during the weekdays when teachers are away working. Programmable thermostats used and maintained as programmed are known to achieve an overall fuel savings of between 5 and 15% over non-programmed thermostats. 9 Alaska Building Science Network – Village End Use Energy Efficiency Program – ’07-’08 Final Report West Region - Atmautluak Elem.
