A building has the following dimensions and characteristics: footprint of 100 ft x 50 ft and 8 stories, 10 feet floor-to-floor height for each floor. The window-wall ratio is 33 Walls have an overall R-value of 20, windows have a U-value of 0.6. The roof has an R value of 30. Building is programmed as all office with 150 square feet per person

Part a

Calculate the design heating load, Q. in BTUH, assuming heating design conditions of 74 degree F inside and 10 degree Foutside and 15 CFM ventilation air per occupant.

Part b

Calculate the annual estimated fuel use in therms, assuming 3,800 degree-days (NYC), 80% efficient boiler, using natural gas at 100,000 BTU/Therm

Q windows annual =
Q wall annual =
Q roof annual
Q infiltration annual =
