For a building located in Boston, Massachusetts with annual heating degree-days (dd) of 5634 and a heating load (heat loss) of 42,000 Btu/h and a design temperature difference of 62°F (68°F indoor and 6°F outdoor), estimate the annual energy consumption. If the building is heated with a furnace with an efficiency of 98%, how much gas is burned to keep the home at 68°F. State your assumptions.
What will be an ideal response?
