Summer Thermal Protection
Comfort and Energy Efficiency During Hot Weather
With climbing outdoor temperatures and more frequent summer heatwaves, summer thermal protection has become a crucial engineering discipline. The objective is to prevent the overheating of interior spaces during hot periods – ideally without the need for energy-hungry air conditioning systems.
Under the German Building Energy Act (GEG), summer thermal insulation must be officially verified for all newly designed buildings as well as substantial extensions. Verification depends on window proportions, solar heat gain coefficients (g-value), shading systems, ventilation rates, and internal thermal mass.
Why is Summer Thermal Protection Vital?
Maximum Living Comfort
Enjoy pleasant, balanced indoor room temperatures even during peak midsummer temperatures.
Zero/Low Energy Demand
Drastic reduction or complete omission of power-intensive cooling devices and air conditioning compressors.
Health & Productivity
Effective protection against physiological heat stress for occupants and office employees.
Real Estate Value
Climate-resilient properties retain significantly higher rental yields and market valuation.
