Just we need to collect the rough details according to the particular area:

  1. Area Length
  2. Area Width
  3. Area Height
  4. Maximum Persons within the Room
  5. Average outdoor Temperature

Also we need to have two Assumptions regarding the temperatures.

Assumption 1:

Assume indoor temperature as 20 Celsius, when the air conditioning process is over (A/C).

Assumption 2:

Assume roof temperature as 35 Celsius. This value is based on outdoor temperature of the area and might be differ from outdoor temperature but generally, when we doing the calculations, we assume it as 35 Celsius.

In this case, we have to complete total 08 calculations to get the final answer.

Calculation 1:

Total Area of walls: A

How to calculate the area of walls: — (Length * Height)*Number of walls + (Width * Height)*Number of walls

The answer should be in square meters (m2).

Calculation 2:

Total Area of floors: B

How to calculate the area of floors: (Length * Width)

The answer should be in square meters (m2).
