How does this lead to Energy Wastage?

26 Jun How does this lead to Energy Wastage?

With the movement of air in or out of a building without a regulation several undesirable occurrences take place.

In the winter the heated air from within the building leak out while to compensate this cold dry air rushes in. The energy used to heat the indoor air is lost while to heat up the fresh air more fuel burn up. The fresh air is dry and causes an imbalance in comfort humidity level within the space. More humidity is therefore added through humidifiers which represent a loss of energy and also water.
• In the summer a reverse process takes place. The Hot and humid out side air representing an additional heat load leak in pushing conditioned cool air out. More energy is used by the Air conditioner to lower and stabilize the indoor temperature and humidity. The leaked out conditioned air is a considerable loss in energy.
• The unconditioned fresh air will bring in pollutants such as spores, pollen, ticks and mites, microbes, dust etc. This necessitates efficient filters which tend to get clogged soon due to their miniscule air passages. They therefore require more power to push air through.
