Problem 1 (50 Points): WSU plans to build a new training center, which is designed as an 8,230 ft2 building comprising two floors. The ground floor consists of a dining area, kitchen, gymnasium, and restrooms. The first floor consists of a classroom, recreation space, office, and store. The structure is primarily wood-frame construction. Building assemblies used in the construction of the training center and associated carbon emissions and solid wastes are described in the followplans to build a new training center, which is designed as an 8,230 ft2 building comprising two floors. The ground floor consists of a dining area, kitchen, gymnasium, and restrooms. The first floor consists of a classroom, recreation space, office, and store. The structure is primarily wood-frame construction. Building assemblies used in the construction of the training center and associated carbon emissions and solid wastes are described in the following table. Assembly Type Description Carbon emissions (kg) Solid wastes (kg) Foundation Cast-in-place concrete retaining walls 50 14576 Floors Light frame wood truss with plywood base finish. Carpet, rubber, cork tile, and ceramic tiles have been used for the floor finishes 23.5 25364 Exterior Walls 2 x 6 wood stud wall with brick cladding + plywood sheathing + R-19 batt insulation + 5/8 gypsum board + latex based paint 30.1 90218 Interior Walls 2 x 6 wood stud wall with 5/8 gypsum board + latex based paint 22.3 11467 Roof Standing seam metal roof with prefabricated wood scissor truss + plywood roof decking + R30 batt insulation 45.6 5268 Doors Hollow core metal doors, solid core wood doors, and French doors 12.5 1452 Windows Aluminum-clad wood window frame with double low-e glazing 34.8 7820 A 60-year building life has been estimated by the structural engineer based on the type of structure, assemblies, and climatic conditions. The annual energy consumption for the training center is estimated to be 17.68 kWh/ft2. The major resources are coal (262 kg/ft2 per year) and natural gas (33.4 m3 /ft2 per year). For 1 kg consumption of coal, carbon emissions are 3.66kg, while 5.41 kg/m3 for natural gas. Please evaluate the overall environmental impact of the training center by identifying the life-cycle stages and determining the inventory analysis results in terms of energy use, resource use and emissions, and waste.
