TEUI L.2 Heating and Cooling Degree Days
If you’re not sure what OBJECTIVE or TEUI3 is, Take me to the Index of Articles! Heating and Cooling Days (HDD and CDD, respectively) are an effective shorthand for defining climate-related impacts on heating and cooling loads of buildings. The idea is simple enough, but the units – a mashup of time and temperature –…

TEUI T.3 Target vs. Actual
First of all, if you’re not sure what TEUI3 is, Take me to the Index of Articles! Architects imagine buildings in great detail before they exist. They establish budgets for construction costs, and their contracts will often hold them to delivering projects within a certain percentage of these targets. The buildings are expected to perform…

The Energy Model vs The Real World
After 2 years of living in our cold-climate Passive House, how is its real performance measuring up to the energy model used during the building’s design phase? An energy model is a digital replica of a building that simulates heat gains and losses based on the building’s characteristics and climate. It allows us to optimize…
