A large office building of 50,000m with three floors above ground is proposed to be constructed in northern Quebec near the arctic circle, at about 67 N latitude. You are invited to participate in the design competition in charge of HVAC systems. a. You shall propose an integrated design of three (3) innovative technologies, which reduce the environmental impact and depletion of natural energy resources. During the preparation for this competition, you visited several similar buildings throughout the world (some examples were presented in the BLDG 472&6781 course this fall term). (2 marks) b. Based on your general knowledge of climate conditions at northern locations, explain the scope of integrating those three innovative technologies. (2 marks) c. Explain shortly the operating principle of each technology. (2 marks) d. Explain the potential disadvantages of integrating the proposed technologies. (2 marks)
