+8. For a **24-hour period** in a 25,893 square foot US office building find the **average hourly heat gains** for the entire building from **people, equipment, and lights** on a typical day.  Use the tables provided in the links below. Provide your answer in BTU/hr.
+	1. Use the upper range value for people and equipment in Table G1.
+	2. Use a daylight factor (DF) of 2 in Table G1.
+	3. The building is occupied for 9 hours on a typical day.
+
+q_internal = A: Floor Area (ft2) × (q_people + q_equipment + q_lights) (Btu/(h·ft2))
+	= 25,893 * (2.3 + 1.1 + 2.0)

+9. For an office building during the winter with an internal setpoint at 69.8F and:
+	4,265 BTU/(hr-F) heat loss rate through the envelope (via convection & conduction),
+	7,445 BTU/(hr-F) heat loss rate from air infiltration,
+	109,869 BTU/hr solar heat gains through south facing windows,
+	131,420 BTU/hr heat gains from people, equipment, and lights,
+	**determine the winter balance point temperature** in degrees Fahrenheit. Provide your answer with one decimal place value.
+
+BPT = T_indoor - Q_i ÷ UA_total
+	= 69.8 - (131,420 + 109,869) / (4,265 + 7,445)
