Abstract
The implementation of innovative materials for energy saving is a main focus in the building sector. In this context, aerogels-enhanced systems are often indicated as promising materials for enhancing building envelope thermal resistance. In particular, aerogel blankets have already shown potential in retrofitting projects, while the development of aerogel glazing systems and aerogel-embedded renders is still object of research. This paper describes some aerogel-enhanced systems that were developed over the last few years at Ryerson University, namely aerogel glazing systems, aerogel plasters, aerogel concrete tiles and panels and aerogel fiber blankets. The results of thermal characterization tests of these new materials are reported. These new systems are then assessed for the retrofitting project of an educational building. An extensive energy audit was conducted through measurements of the envelope hygrothermal parameters, the building air-tightness, and several indoor environmental parameters. The audit helped to create an accurate energy model that was used for assessing several energy saving measures.
