Arguably the most important step in creating an energy-efficient building is the effective use of insulation.
No matter what renewable energy source you choose to install to heat, or cool, a building, you will see the most benefit when you can effectively maintain a room’s temperature.
Whether you choose an air source heat pump, a geothermal heat pump, or even an HVAC system, if a building is not adequately insulated, you will end up losing a large amount of that created energy through the walls and ceiling.
This is not only a waste of the energy used by can also be unnecessarily expensive.
Insulating a building effectively means ensuring that the walls, ceilings, doors, windows, and floors are all insulated.
The type of insulation you choose for your walls will depend on whether they are cavity walls or solid walls. You can insulate either type of wall, and it is estimated that this could reduce your heat loss by up to a third.
A quarter of all heat lost from a building goes through the roof. A well-insulated ceiling can significantly reduce this loss and decrease the energy resources needed to maintain a room’s temperature.
The best way to insulate the doors of a building is to ensure you have installed energy-efficient doors and any windows on the doors are double or triple glazed.
It is also essential to block any draughts around a door to make sure unwanted air isn’t entering the building.
Like door insulation, the most important way to ensure your windows are effectively insulated is to use double or triple glazing.
Floor insulation is designed to reduce the amount of cold air that comes up from below the floor. Insulating beneath the floor of a building reduces heat loss, prevents draughts, and makes a room more comfortable throughout winter and summer.
