Recently, researchers have found out that simply keeping a bedroom door closed can adversely affect comfort, safety and health in a house. This is because it blocks the air’s pathway, thus reducing air flow into the room and through the system as well. Pressurization of the room, which is caused by air trapped within the space, forces the cool air out of the house. All this has a significant impact on the energy efficiency of a house. How Closed Doors Affect Energy Efficiency When air is forced out of a room under pressure, an equal amount needs to be drawn so as to replace the expelled draught. Depending on the number of closed doors, the rate of entry of hot or cold outside air could go up by anything between 300% and 900%. This raises utility bills, decreases comfort and brings in a host of health problems. Since fluids seek the path of least resistance, […]
