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 =

In a unit cell of fcc structure, indicate the position of one of the tetrahedral interstitial sites by plotting the corresponding tetrahedron. do the same for one of the octahedral interstitial sites (in a separate fcc unit cell). mark the positions of all the tetrahedral and octahedral interstitial sites in the unit cells. how many equivalent tetrahedral sites and how many equivalent octahedral sites are contained in a fcc unit cell, respectively. what is the coordination number for a tetrahedral site and what is the coordination number for an octahedral site?
