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
Reference. The British Thermal Unit, or BTU, is an energy unit. It is approximately the energy needed to heat one pound of water for 1 Fahrenheit. 1 BTU = 1,055 joules. 1BTU/hour = 0.293 watt.Examples 1  : One very well-insulated 1,000-square-foot home in Boston needs around 24,000 BTUs to heat in winter.lease note that this calculator can only gauge a rough estimate. You should also consider factors like efficiency decrease of the heater or air conditioner with time, the shape/type of your home or room, insulation conditions, and other factors. 1 watt is approximately 3.41214 BTU/h.
