Examples of system door and window energy saving

Example: 100 square meters of two rooms and one living room, the window area of about 30 square meters. The insulation performance of the system doors and Windows is better than that of ordinary doors and Windows. Let's calculate the relevant data:


1. Open air conditioning with ordinary doors and Windows every day, and the power consumption is 30°.


2. Turn on air conditioning every day with system doors and Windows, and the power consumption is 25°.


3. The electricity fee is calculated at 1 yuan/hour. System window 1200 yuan/square meter, ordinary doors and Windows 800 yuan/square meter.


Annual cost savings of opening air conditioning :(30°-25°) *365*1=1825 yuan.


Door and window cost difference: system door and window cost - common door and window cost = 30* 1200-30 *800 =12000 yuan.


From this, 12000÷1825≈6.5 years is calculated!


The general design term of the building residence is 70 years. We can recover the cost beyond the building Windows in only 6 years. The system doors and Windows make the building energy efficient for 64 years!
