The HEX is an indicator of a home’s energy performance. It is derived from monitoring the temperature at certain points over a period of time under controlled conditions.
Stack Effect “Stack Effect” is the common term used to describe the effect of excessive air leaks in the upper portions of a home, which causes underpressure
The stack effect refers to an underpressurized house, usually due to a loss of warm air to the attic space. This can be dangerous because when the air pressure
Without more information, I assume that the gas furnace is in the basement, the wood-burning fireplace on the first floor, on an exterior wall, that the home is
Unfortunately, the user manual of the Trane XR90 furnace offers no explanation of what the blinking light means that can be seen behind a small hole in the
How much heat transfers through an exterior wall into the environment in a given period of time? The theory of Thermodynamics, specifically the formulas for heat conduction using thermal resistance, offers a
The underlying idea here is that, since energy is lost to the environment through the surface of a home, minimizing the surface area will minimize energy losses. The
An unheated garage is technically not part of a home for the purpose of calculating form factors and surface areas. Garages are kind of an “in-between space” that
