What is an energy efficient metal roof?
Energy efficient metal roofing and wall systems, reduce the carbon emissions and also the cost of the operational energy costs of heating & cooling the building itself, reducing the pressure on electricity generation.
When people think of energy efficient or green roofs they consider options such as solar panels, wind turbines and green or sedum roofing systems, but there are easier, cheaper and more effective solutions to providing energy efficient roofs.
How are roofs designed and built prior to SANS 10400 XA Legislation?
Single skin roof applications provide little benefit to maximising the energy used to cool or warm the inside of the building to the desired temperature. Cooling or heating the inside of any building is a continually rising cost for any building today.
The installation of a single skin application is fraught with danger as the installers use boards and walk purlins or rafters. Both practices highly dangerous when working at heights.
Key factors that have to be considered to offer the best savings and SANS 10400 XA Compliance for an energy efficient metal roof?
- U-value of the external fabric.
- Minimise energy loss due to thermal bridging (values).
- Minimise energy loss due to air permeability through the building envelope.
- Minimise the risk of surface condensation.
How do we achieve an Energy Smart Design or an energy efficient metal roof?
Energy smart design has been practiced for many decades, in northern hemisphere countries, to retain heat and energy within the building. The same principles are used to ensure retaining cool air saving you operational costs in the generation of that energy.
- Comprehensive specification and design.
- Robust detailing ensuring air tightness and keeping the energy (cool or heat) in the building.
- High quality materials, components and built up systems.
- Independently audited installations to ensure compliance.
