Lean - Abstract:
- The increasing demand in energy savings in commercial buildings business has focused attention on both DC power buses and chilled beam systems. Data centers are increasing rapidly all over the world. DC power distribution in data centers has potential because the servers located require DC power transmission for operation. The AC to DC conversion losses can contribute to a significant waste of energy. Instead of using numerous conversions in power equipment could be coupled directly to DC bus system having a variety of DC voltage levels available. In this study, the efficiency of DC system is compared to the traditional AC system and the results demonstrated that power losses in DC system with four conductors are minimal. Different construction procedures will be enlisted to determine the cost-benefits of building designs. The Chilled beam system promises to be a great energy saving system relative to conventional building cooling subsystems. However chilled beam systems have some drawbacks and these will be highlighted and solutions are provided and a practical application of chilled beams at a Hiranandani, Mumbai project is given. The simple cost and payback analysis of a chilled beam system is calculated in this study. The research illustrates the need to look at overall systems approaches to achieve substantial energy savings in typical commercial building applications. And as vendor selection plays a key role in improving the cost and quality of a particular project. TOPSIS analysis will be performed to evaluate the best criterion affecting the function of selection.
