Draught proofing is a simple implementation, which can save up to 100% energy costs.
A variety of products are available on the market to improve those leaking gaps, which are particularly prevalent in older buildings. Look out for gaps under doors and around windows; unnecessary vents, especially when building new or renovating (check with your builder). Gaps in un-insulated wooden floorboards, faulty construction, unprofessional installations and wrong adjustments of fresh air supply and exhausts, badly designed and installed ducted air-conditioning systems, and lift shafts.


Example: One room using one 2.0 kW/h heater, running 8 hrs overtime due to draft can cause 100 % extra energy consumption when heating or cooling.
