Saudi's Kafaa: Building thermal insulation key to energy efficiency
Thermal insulation can extend building lifespans, reduce structural cracks, and improve fire resistance
The Saudi Energy Efficiency Centre (Kafaa) has called for the application of thermal insulation in buildings, stating that it increases electrical energy efficiency by 30% to 40%.
Thermal insulation reduces heat transfer through building parts, especially walls, ceilings, and windows, as well as external elements, whether it is in terms of thermal loss during winter or in terms of thermal gain in summer.
In addition, the use of double and reflective glass reduces up to 5% of the air conditioner’s consumption of electricity.
Apart from lowering electricity bills, it also reduces the high costs of operation and maintenance, and extends the lifespan of appliances and home furniture, the state-run Saudi Press Agency reported.
Thermal insulation can also extend building lifespans, reduce structural cracks, improve fire resistance, lower structural loads, and protect the environment.
The entity has called for building owners in the kingdom to also use light exterior colours on buildings, as it reduces heat absorption from thermal gain.
The centre showed that the cost of thermal insulation in buildings, is estimated at 5% of the total cost of the building, which is acceptable compared to the benefits that the building will accrue as a result of implementing thermal insulation applications.
