Thermal efficiency refers to a building’s intrinsic ability to maintain a stable indoor temperature. The greater its thermal efficiency, the lower its energy needs are for heating and cooling. When renovating your home, it is possible to increase its thermal capacity with:
- Insulation
- High-Performance Windows and Doors
- Ventilation Systems
Insulation
Thermal efficiency is increased by insulating walls (internally or externally) as well as the floor and roof. Insulation creates a barrier that reduces heat transfer by either reflecting thermal radiation or decreasing thermal conduction and convection.
There are many eco-friendly insulation products, including: Sheeps Wool, Cotton/Demin, Icynene, Polystyrene (its energy-saving benefits outweigh the material’s drawbacks), Aerogel, ThermaCork and Cellulose.
High-Performance Windows and Doors
These high-tech products block up to 70% of solar heat gain in summer and reflect heat indoors during winter, dramatically increasing thermal efficiency.
The Archier-designed Corner House, pictured above, features advanced window systems from BINQ’s Archetto.
Crafted from 68mm-thick timber profiles, they offer maximal thermal efficiency to make large-scale windows an energy-saving option.
Ventilation Systems
Installing an energy recovery ventilator (EVR) or a Heat recovery ventilation (HRV) system can significantly improve thermal efficiency. These air exchange systems help to enhance indoor air quality and minimise heating costs. They retain existing heat and optimise the interior moisture content in the air. For a more affordable option, a non-ducted smart system is easy to install and can provide very effective ventilation for a low price.
