How to estimate energy loss through windows?
Energy demands are always on the rise. With this rise in demand, it is important to identify modes of energy loss so as to conserve it or prevent the loss. Heat loss through windows is one such mode of energy loss.
Heat passes through the glass (transparent) of window via:
- Sunlight which is Electromagnetic Radiation in the infrared range
- Its thickness via Convection – Conduction – Convection
Estimating heat loss through windows:
- In order to estimate heat loss or gain through windows due to sunlight is slightly complex and can usually be equated to the external temperatures.
- On the other hand, we can calculate the heat loss through windows via its thickness with the simple calculator provided below.
