Let's calculate how much money O’DAS insulated windows and doors can save you each year.

Energy Saving Calculator
- Environmental protection starts with me.

Calculation Formula:

ΔQ=ΔU*ΔT*t*N/1000 =( U1-U2)*(T1-T2)*t*N/1000

 

Parameter Explanation:

ΔQ: Energy saving (kWh).

 

U1: Heat transfer coefficient of insulated aluminum alloy hollow glass windows (W/m2·K).

U2: Heat transfer coefficient of ODAS doors and windows (W/m2·K).T1: Outdoor temperature (℃).

T2: Indoor temperature (℃).

t: Heating/cooling time per day (hours).

N: Number of heating/cooling days per year (days).

 

For example, if we calculate based on a 120㎡ three-bedroom apartment in New York with a window area of 24㎡, we can use the formula to get: ΔQ=ΔU*ΔT*t*N/1000=( 2.8-1.46)*(18-1.3)*24*120/1000 =64.45 kWh

 

This means that every square meter of doors and windows will save 64.45 kWh of heating electricity each winter, and the overall energy savings will be 64.45*24 =1546.8 kWh.

 

Using ODAS thermal break window & doors can save electricity costs of 0.55 RMB/kWh*2078.4 kWh=1143.12 RMB per year (three months).

Currently, China’s carbon emissions are about 10 billion tons, and the carbon emissions from the construction and operation of buildings account for nearly 40% of China’s total carbon emissions. If energy-saving doors and windows are widely promoted and used in the country, it can directly reduce carbon emissions by 214.78 million tons.ODAS Windows and Doors adopt strict and rigorous material selection and inspection standards, use green and environmentally friendly materials, have a professional R&D team for design, and an 4.0 intelligent factory for processing and manufacturing, which can achieve excellent energy-saving and insulation effects.

 

ODAS Windows and Doors are the focus and implement the “energy-saving doors and windows” standard, contribute to the low carbon world.
