For the purpose of this section, the following definitions shall apply: "ASHRAE" is the American Society of Heating, Refrigeration, and Air Conditioning Engineers. "Degree day" is a unit, based upon temperature difference and time, used in estimating fuel consumption and specifying nominal heating load of a building in winter. For any one day, when the mean temperature is less than sixty-five (65) degrees Fahrenheit, there exist as many degree days as there are Fahrenheit degrees difference in temperature between the mean temperature for the day and sixty-five (65) degrees Fahrenheit. "Glazing" is all transparent or translucent materials in exterior openings. "Exterior wall area" is the gross area of wall surfaces adjacent to heated spaces, including glazing and doors, exposed to ambient climatic temperatures measured for a dwelling unit or group of units served by a heating system. "Infiltration" is air flowing inward as through a wall, crack, etc. "Special glazing" is glazing which has a minimum U factor of .07 for all glazed surfaces. "Thermal conductivity (K factor)" is the time rate of heat flow through one square foot of homogeneous material one inch thick when there is a temperature difference of one degree Fahrenheit between the opposite faces of material expressed in Btu/hour, square foot, degree Fahrenheit per inch. "Thermal resistance (R)" is the measure of the resistance of a material or building component to the passage of heat. The resistance value (R) of mass-type insulations shall not include any value for reflective facing. "Transmissivity" is the capacity of a material to transmit radiant energy. "U factor" is the total heat flow through a given construction assembly, air to air, expressed in Btu/hour, per square foot, per degree Fahrenheit temperature difference. -10- U = I Rt where Rt equals the sum of the resistance (R) for the individual components of the assembly, U factors shall be calculated according to ASHRAE methods. "Unheated spaces" are any spaces exposed to ambient temperatures and not provided with a heat supply capable of maintaining a minimum temperature of forty-five (45) degrees Fahrenheit.
