Construction defects drastically reduce energy efficiency and sustainability
Defects and errors are common in home construction, resulting in lower efficiency and sustainability. A recent study by the Institute for Building Research (IFB), commissioned by the Building Owners’ Protection Association (BSB), shows this.
The 8 most common construction defects affecting the environmental performance of buildings are:
- Thermal insulation (material, approval, and execution): 47%
- Missing documentation: 46%
- Airtightness (roof and upper floor ceiling): 40%
- Windows and French doors (quality, fastening, and sealing): 34%
- Moisture damage (efficiency): 27%
- Thermal bridges and summer thermal discomfort: 25%
- Building systems services (heating, photovoltaics, and heat pumps): 21%
- Building systems services (ventilation and indoor hygiene): 13%
