Heating, ventilation and air conditioning systems usually account for more than 50% of a building's total annual energy consumption, which is one of the largest operating expenses for property owners. Choosing the right wall insulation material is the most cost-effective way to reduce long-term HVAC cost, and EPS Cement Sandwich Wall Panel has been proven to deliver far better energy saving results than many traditional wall insulation solutions.

The closed-cell EPS core inside EPS Cement Sandwich Wall Panel has a thermal conductivity as low as 0.032 W/(m·K), which creates a highly effective thermal barrier between indoor and outdoor environments. In summer, when the outdoor temperature rises to 38 degrees Celsius, the heat transfer speed through the wall is extremely slow. Even if the air conditioner is turned off for 2 to 3 hours, the indoor temperature will not rise rapidly. This greatly reduces the continuous working time of the air conditioning compressor.

In winter, the wall panel can lock the indoor heating heat inside the building very effectively. Many residential users in cold northern regions have reported that after replacing old brick walls with EPS Cement Sandwich Wall Panel, they can keep the indoor temperature at 20 degrees Celsius even when the outdoor temperature drops to minus 10 degrees Celsius, while the previous monthly heating gas bill was cut by nearly 45%.

For large commercial buildings such as supermarkets, logistics warehouses and exhibition centers that cover tens of thousands of square meters, the long-term HVAC cost saving brought by this wall panel is even more staggering. A 10000 square meters logistics warehouse in subtropical area once did a comparison test: after using EPS Cement Sandwich Wall Panel to replace the original color steel foam wall, the annual total electricity cost of the warehouse cooling system dropped from 120000 dollars to 52000 dollars. The extra investment on the wall panel was fully recovered in less than 3 years through the saved electricity bills.
