A building is located in Baltimore, Maryland where the annual heating degree days are 4,654. The building has a heating load (heat loss) of 30,000 Btu/h, and a design temperature difference of 52°F (68°F indoor and 16°F outdoor). Estimate the building’s annual energy consumption. If the building is heated with a furnace with an efficiency of 92%, how much gas is burned to keep the home at 68°F? State your assumptions.
What will be an ideal response?
Assuming natural gas with a heating value of 1,000 Btu per cubic foot and the furnace
has an efficiency of 92%, the amount of natural gas required to keep the home at 68°F is
