A new residence has been designed and built in Connecticut. The property is 30 by 100 by 10 ft with an uninsulated slab on grade concrete floor. Details of the construction are provided as follows: Walls: 4 in. face brick, 3/4 in. plywood sheathing, 4 in. cellular glass insulation, and 1/2 in. plasterboard Ceiling/roof: 3 in. lightweight concrete deck, built-up roofing, 2 in. of rigid, expanded rubber insulation, and a drop ceiling of 1/2 in. acoustical tiles, some 18 in. below the roof. Windows: 45% of each wall is double pane, non-operable, metal-framed glass (1/4 in. air gap). Doors: Two 3 by 7 ft, 1.75 in. thick, solid wood doors are located in each wall. ● ● ● ● The infiltration rate is estimated to be approximately 0.5 ACH. The following design conditions have been specified as follows: Indoor Outdoor Temperature (F) 72 3 Relative Humidity (%) 30 100 Humidity Ratio 0.005 0.00092 Determine the heating load of the property (where applicable, specify the sources of reference from where you obtain / assume the relevant values used). If the client decides to build a basement space underneath the current floor, provide an analysis on how it may affect the current heating load.
