A particular glazing system has center-of- glass characteristics as follows: Visible U-Value W/m² Transmittance 27 Consider the following scenario: Beam solar radiation (measured in direction of travel) = 700 W/m² strikes at incident angle = 20°. Diffuse solar radiation = 270 W/m² (measured in the plane of the glazing). There is no interior shading device. 325 SHGC Incidence Angle (Beam Radiation) 40⁰ 50 60 70 0.78 0.70 0.67 0.54 0.58 0.45 0.23 The total solar heat gain (W/m²) is closest to which of the following choices? 400 475 550 Hemispherical Diffuse 0.60 625 700 Question 8 (1 point) The estimated annual load duration curve to be met by a boiler plant is shown below. Only those hours occurring during the heating season are depicted. The plant will consist of three boilers, each with rated input = 245 kW and rated output = 200 kW. Load (kW) 600 500 400 300 200 100 0 1000 Load Duration Curve 2000 3000 Hour Number 4000 5000 On an annual basis, the total number of hours during which all three boilers must be operated to meet the load is closest to which of the following options?
