Long Term Monitoring

If seasonal variations and occupant effects are key concerns, long-term monitoring is more appropriate than short term monitoring. Typically these homes are occupied (except in special circumstances such as lab houses, where occupancy effects are eliminated or simulated) and therefore allow investigations of house performance under realistic operating conditions, which include human interactions, range of weather conditions, and equipment degradation over time. An inherent complication with occupied long-term monitoring is that occupant behavior cannot be controlled; however, it must be noted that the performance of the building with real occupants is ultimately the relevant metric.
