Most people will tell you that ICT is a shortening for âinformation and communications technologyâ â option number one above. Letâs unpack that phrase. So it is âinformation technologyâ or âcommunications technologyâ. It is not âinformationâ or âcommunicationâ standing on its own. âInformationâ or âcommunicationâ has to go with technology â they cannot exist independently. You could shorten information and communications technology to just technology. Option 2
For example, a 24 ft. x 24 ft. garage with an eight-foot ceiling has a volume of 4608 ft.3 (24 * 24 * 8 = 4608) Final Formula. Once you have all the data assembled, multiply them together and divide by 1.6 to find the number of BTUs required to heat your garage. (Insulation * Volume * Temp. Rise)/1.6 = BTU. For example, if your garage was 4608 ft. 3 in volume, your temperature rise was 20Â°F, and your insulation rating was one, it would be: (1 * 4608 * 20)/1.6 = 57,600 BTU
At 40 to 45 BTUs per square foot, you'd need a 100,000 to 112,500 BTU furnace to heat your 2,500-square-foot home. A heating degree-day calculation, using the month of July as a factor, is a more precise way of estimating furnace size. Natural gas for a furnace is priced by the therm, or per 100,000 BTUs. Therms are listed on your home's gas bill in annual and monthly usage rates. The heating degree-day calculation for a furnace is 50 x heating therms x furnace efficiency = load in BTUs/hour.
