POE: Comfort and Energy Consumption

Posted by on Aug 13, 2014 in Post-Occupancy Evaluation | Comments Off on POE: Comfort and Energy Consumption

This post is part of a series on post occupancy evaluation (POE). Click here for the main article.

When assessing energy consumption it is critical that buildings are “normalised” for thermal comfort.  For example, if you keep your home at 15 oC throughout the winter then your energy consumption will be much lower than a house at 20 oC (if all other conditions were the same then this would represent a rough doubling in energy consumption).

Typically, temperature and humidity are measured as a reflection of internal comfort. We have this data for most of the projects.  CO2 and VOC levels are useful to understand the air quality, but are more expensive to monitor, and we haven’t included this information here.

In addition, measuring the in-use ventilation rate would be interesting, but is not often undertaken as it’s much harder to do, and whilst it does have an impact on the energy consumption it is not as significant as the internal temperature.
