The most cost effective measures your organisation can implement to reduce your energy bills are to reduce heat loss caused by the building fabric itself. To achieve a reduction in heat loss, the first important step is to add the insulation to roofs, walls and floors. The majority of existing properties have insufficient amount of roof insulation and the amount is dependent on the types of insulation used. In modern construction, cavity walls are usually used which are required to fill with poly-isocyanurate or polystyrene balls.
A second important factor to consider is heat loss through windows which could be another vital component of heat loss. To achieve this, double glazing or even triple glazing is a significant improvement to prevent transferring heat or cold and it has been adopted wide scale throughout the UK.
Before installing radiant heating systems with various output values, the heat load calculation is necessary. In general, the heat load is contributed by two parts: fabric heat loss and ventilation heat loss. Both should be processed separately for each room in the house. There are 6 steps to find it:
- Find the temperature difference between indoor design temperature and outdoor design temperature.
- Calculate the surface area for wall, roof, floor, window, and door.
- Investigate the U value
- Calculate wall surface heat loss
- Calculate total fabric heat loss including roof, floor, window, and door.
- Find ventilation heat loss
