This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT:There is currently no comprehensive model which considers multiple performance criteria in choosing HVAC systems. This dissertation aims at developing an integrated decision-making model for selecting HVAC systems based on various performance criteria, including technical performance, environmental performance, economic performance and LEED performance. An analytical hierarchy process (AHP) method is used as the basis of the decision-making model to generate the optimal HVAC system. The preference weightings of performance criteria are assigned to the hierarchy structure based on the preference of the decision-makers. The weightings of the performance criteria are further integrated with the performance indicators of alternatives to calculate an overall score for each HVAC alternative of interest. With the decision-making model, the alternatives are ranked by the overall scores and the alternative with the highest score indicates the optimal HVAC system based on its comprehensive performance and preferences of the decision makers. A case study is conducted to further test the validity of the methodology. Sensitivity analysis and consistency checks are conducted to track the sensibility and accuracy of the model. This dissertation also provides thoughts on the development of software for the decision-making model for the purpose of facilitating the programming process and reducing the complexity of the model inputs and outputs.
