The performance of two demonstration houses, built and occupied throughout 2013, were measured through a combined quantitative and qualitative assessment. Two families occupied the houses over a 9- & 12-month period of assessment. The factors measured were temperature, relative humidity, CO2 concentration and daylight levels. A Building Management System monitored the readings at quarterhour intervals and the living experiences of the occupants were documented through bimonthly questionnaires, phone interviews and blog entries. Energy and carbon consumption data were also assessed, as well as the families’ lifestyle and its changes over the monitoring period.
