A commercial office building is located in the city of Lansing, Michigan, and is heatedusing a gaseous fuel with a heating value of 725 Btu/std ft3. The indoor designtemperature is 71ºF. The heat load for the building is known to be 250,000 Btu/hr. Thisheat load accounts for the fact that there are internal heat gains in the building, due tothe presence of people and electronic equipment (e.g., lights and radios). People in thebuilding are usually seated and involved in light activity.a) The furnace had an initial efficiency factor of 73% when installed, but since thenefficiency-improvement retrofits were implemented that raised the efficiency factorto its present value of 82%. The building was designed using the 99% designheating temperature value for the city to determine the outdoor design temperature.Evaluate the annual fuel quantity (in std ft3) required to heat the building, using thedegree-day or bin method.b) Seventy people use the building, but the occupancy pattern for the…

The pressure difference due to stack effect for this building is assumednegligible due to it having only a single floor. The dominant mean wind speed fordesign is assumed to be 15 mph. The house orientation is such that it is normal to thedominant mean wind direction.The house was built recently and all of the windows and doors are tight fitting. Thehouse construction and materials are typical for Ottawa, Ontario. The doors are 3 ftwide and 6.75 ft high. Each of the windows is double hung and each window has thefollowing overall dimensions: 3 ft wide and 4 ft high.
