The CLTD/CLF/SCL (cooling load temperature difference/cooling load factor/solar cooling load factor) cooling load calculation method was first introduced in the 1979 ASHRAE Cooling and Heating Load Manual (GRP-158) [1] The CLTD/CLF/SCL Method is regarded as a reasonably accurate approximation of the total heat gains through a building envelope ...
Air changes per hour, abbreviated ACPH or ACH, or air change rate is the number of times that the total air volume in a room or space is completely removed and replaced in an hour. If the air in the space is either uniform or perfectly mixed, air changes per hour is a measure of how many times the air within a defined space is replaced each hour.
A mortgage calculator can help to add up all income sources and compare this to all monthly debt payments. [citation needed] It can also factor in a potential mortgage payment and other associated housing costs (property taxes, homeownership dues, etc.). One can test different loan sizes and interest rates.
Metabolic rate is the rate of transformation of chemical energy into heat and mechanical work by metabolic activities of an individual, per unit of skin surface area (expressed in units of met) equal to 58.2 W/m 2 (18.4 Btu/h·ft 2), which is the energy produced per unit skin surface area of an average person seated at rest.
Interest rate. 30-year loan term — monthly payment. Total interest paid over life of 30-year term. 15-year loan term — monthly payment. Total interest paid over life of 15-year term. 5.00% ...
The air exchange rate, (I), is the number of interior volume air changes that occur per hour, and has units of 1/h. The air exchange rate is also known as air changes per hour (ACH). ACH is the hourly ventilation rate, divided by the building volume. It can be calculated by multiplying the building's CFM by 60, and then dividing by the building ...
Falling construction numbers will have both long- and short-term effects on the housing market. In the immediate term, lower construction numbers mean lower inventory levels—preventing the drop ...
A mortgage point could cost 1% of your mortgage amount, which means about $5,000 on a $500,000 home loan, with each point lowering your interest rate by about 0.25%, depending on your lender and loan.
