Abstract
Houses give off a high percentage of a country’s total carbon dioxide
emissions. In Taiwan, the figure is about 28%. Since carbon dioxide is one of the
greenhouse gases, houses contribute strongly to global warming. One way to cut the
greenhouse emissions of houses, and therefore help stop global warming, is to
minimize the energy use needed to sustain comfortable living in a house.
The main goal of this research is to apply the RETScreen Clean Energy Project
Analysis Software which was developed by the government of Canada to evaluate
energy saving projects for school buildings. We evaluated the energy savings,
energy efficient, costs, emission reductions, financial viability and risk for various
types of common or feasible energy saving projects for school buildings. The
research was carried out by the following procedures, studying operating logic of
the RETScreen software platform, collecting the parameters of the energy saving
projects, making the simulations, and analyzing the results. The results of this
research showed that the outputs of RETScreen were consistent with the actual
situations and reasonable expectations. We can also say that RETScreen’s built-in
product, project, hydrology and climate databases were valuable to make some
domestic energy saving analysis. In addition, it could be proved that RETScreen
Software can help planners and decision-makers to better analyze the technical and
financial viability of possible energy saving projects. People can reduce the cost of
pre-feasibility studies and make better decisions to implement renewable energy,
and energy efficiency projects by applying RETScreen.
