A material with high heat capacity and low conductivity will have a ___

___ can reduce the heat loss by up to 40%

The ___ the solar gain factor the lesser the heat transfer through windows or openings

___ is the heat flow rate through a unit area of the body when the temperature difference between the two surfaces is 1ºC

___ of a substance is the amount of heat energy necessary to cause unit temperature increase of a unit mass of the substance

___ is the measure of hotness or coldness

___ is defined as  the rate of heat flow through unit thickness of the material per unit area, when there is a unit temperature difference between the two sides

The ___ the resistivity, the better the insulating property of a material.

The ___ is defined as the outside air temperature which, in the absence of solar radiation, would give the same temperature distribution and rate of heat transfer through a wall

The time period required for the heat wave to propagate from the outer surface of the wall to its inner surface is called ___

In warm climate (heat gain situation), a ___  surface conductance would help in reducing solar over‐heating

SHGC is expressed as a number between 0 and 1

The ___ is the ratio of the maximum outer and inner surface temperature amplitudes taken from the daily mean

___ is a barrier that minimizes the transfer of heat energy from one side to another

In cold climates, insulation slows the hot outside air from entering the cool inside and in hot climates insulation slows down the heat from leaving the house.

Different form of insulation

In the day time heat flows from the outdoors into the building, where some of it is stored, and at night during the cool period the heat flow is reversed: from the building to the outside. This is called

The thermal balance, is given by: Qi + Qs ± Qc ± Qv ± Qm – Qe = 1

___ is the fraction of solar radiation admitted through a window
