How to Reduce Building Heat Loss by 40%
Proper insulation is the most cost-effective way to reduce energy consumption in buildings. Our analysis shows that adding 100mm of mineral wool insulation to a standard brick wall can reduce heat loss by up to 40%. Key strategies include: 1) Addressing thermal bridges around windows and doors, 2) Installing continuous insulation layers, 3) Using reflective insulation in attic spaces, 4) Sealing air leaks with proper vapor barriers. The optimal insulation thickness varies by climate zone: 100-150mm for temperate climates, 200-250mm for cold regions. Energy retrofits typically pay for themselves within 3-7 years through reduced heating costs, with government incentives available in many regions for energy-efficient upgrades.
