| This Master's Degree Project evaluates studies done in the past and conditions under which large energy savings can be achieved through daylighting of perimeter office spaces in Canada. This project further investigates the potential for displacement of electric lighting, using DOE2.1E and EE4 energy simulation programs. Savings obtained with daylighting were analyzed in terms of energy end use, energy cost and payback period for lighting controls.; Lighting is a major electrical energy end-use in buildings, accounting for 40 percent of total electricity use. Results indicate that past studies substantially underestimated the potential for use of daylighting in northern climates. A payback period of 2.1--2.6 years seems possible for north zone perimeter offices, indicating significant potential of using daylighting for commercial buildings in Calgary.; Keywords. Daylighting, Perimeter offices, Blind use, Lighting controls, Energy efficiency, Cost efficiency. |
