calculate window U-value based on given data in figure

2. Calculate Passive House's energy demand. a, Calculate window U-value based on given data in figure. Uglass=0.6m2CwUframe=1.6m2CWUtotal=AreatotalArea1U1+Area2U2+AreatUi b, With the calculated U value for the windows find out how much power needed to maintain 20C in a home with outside of 0C based on the following: the house having a square footprint 17m by 17m, walls 2.5m high ( Uwalls=0.15m2oCCW, each of the four walls hosting two windows, and each window having an area of 2m2. The entry door area is 2.5m2(Udoor=0.65m2CW). What are the heat loss rates for the installed windows, the door, the walls, the ceiling, and the floor? What is the overall heat loss rate of the home? c, 1. What do these calculated heat loss rate values mean? 2. What is the definition of the passive house? 3. What does the U-value represent? Use its unit as a hint and describe it with your own worlds
