ABSTRACT: Insulating concrete forms (ICF) are generally stackable, hollow, polystyrene blocks into which concrete is poured to form walls in residential and commercial buildings.
ICF walls have many advantages, including ease of construction, high thermal resistance, thermal mass and airtight construction. These attributes should lead to lower heating and cooling energy consumption, increased comfort and reduced space-conditioning systems capacity requirements.
While ICF building systems have been available for many years, builders, owners and developers need quantitative performance monitoring data and analysis to better understand the energy-related performance of ICF. CMHC, in partnership with the Ready Mixed Concrete Association of Ontario (RMCAO) and the Jamesway Construction Group, initiated a research project to measure the thermal performance and air leakage characteristics of an apartment building constructed using an ICF system.
