Long-Term Results from Evaluation of Advanced New Construction Packages in Test Homes: Martha's Vineyard, Massachusetts
This report presents a cold climate project that examines the relationships among very energy efficient single-family residential thermal enclosures, room-to-room temperature variations, and simplified space conditioning systems. The project is located in West Tisbury, Massachusetts, on the island of Martha's Vineyard, and allowed for the comparison of room-to-room temperatures in four virtuallyidentical houses that were all built to the same construction standard. The four homes each has a single ductless heat pump unit (DHU) located in the main living space and radiant electric resistance panels in each bedroom with individual thermostatic controls. Results indicate that temperature fluctuations in the living room due to aggressive setup and setback of the DHU may contribute tohigher percentages of time where the bedroom temperatures were within +/-2 degrees F of the living room temperatures. Solar gains in the living room, door opening/closure and occupant manipulation of thermostats appear to have had a significant impact on room-to-room temperature differences, as would be expected.
