Spray Foam Insulation in Olds, AB.

61.2% single-detached is on the low side for a town of 9,209, and that is largely the college's doing: a post-secondary campus supports rental and multi-unit housing that a purely agricultural town of the same size would not have.

Rental multi-unit stock changes the insulation problem in a specific way. The person paying the heating bill is often not the person who decides whether the attic gets sealed, and a building with a dozen suites has a dozen thermostats setting a dozen different indoor conditions against the same shared assemblies. Of the 1,330 pre-1980 dwellings here, the ones in that category tend to be the last to be addressed and the most expensive to run.

Olds is assigned RED DEER REGIONAL A (climate ID 3025480), about 60 km north: 5,619 heating degree days at an 18 °C base, an average January daily minimum of -17.6 °C, a recorded extreme of -43.8 °C. That is a borrowed reading; there is no Olds station in the 1991–2020 normals set.

The town's own published climate table lists a warmer January mean minimum of -14.3 °C. It is carried here as colour rather than as a correction — town's own published Wikipedia/Environment Canada climate table; period not confirmed as the standard 1991–2020 normal. The two figures are not measured over the same period and should not be read as a disagreement.

Olds College of Agriculture & Technology anchors the local economy alongside canola and barley agriculture, and the Olds-Didsbury Regional Airport business park — shared with Didsbury, at the Highway 27/2A junction — carries the light-industrial side.

A college campus is a set of buildings from many decades held to one operating standard: residences, shops, labs and barns, each with a different envelope and all on the same utility account. That is a portfolio problem, and the sequencing question is which building leaks most per dollar spent.
