The lab studies indoor environments and energy use in homes in cold regions.

AboutAbout the lab
Rethinking housing in cold regions through the environment and building services.
The Architectural Environment Lab studies indoor environments in buildings, building services such as air conditioning, and how energy is used.
Student research topics include insulation retrofits and energy saving in homes in cold regions, indoor environments and energy poverty in low-income households, and the health of older people in relation to their housing.
The lab also works on estimating solar radiation from point cloud data and on making building energy use visible on maps.
Arctic region research is another of the lab's fields, and the lab has exchanges with partners overseas, including in Mongolia and Finland.
Key terms
- Energy poverty
- A situation in which heating and other utility costs are a heavy burden relative to income, so a household cannot keep its home at a temperature that is safe for health
- Insulation retrofit
- Construction work that adds insulation or high-performance windows to the walls and windows of an older home so that heat escapes less easily
- Point cloud data
- A collection of countless points, obtained by laser scanning or similar methods, that mark the positions of an object's surfaces. It can record the shape of buildings and cities in three dimensions
