Critical Review and Suggested Improvement for the Alternative Air Dissertation

Critical Review and Suggested Improvement for the Alternative Air Cooling - Dissertation Example New buildings should use alternative methods for air quality too. This research will show how and why. 1.1 BACKGROUND TO THE PROJECT There are many buildings in Hong Kong that were built before alternative methods for cooling and cleaning the air inside were financially profitable. Now the prices have dropped down, so it makes sense to install these alternative methods that save energy and some which also have a lower carbon balance quotient. These also save money in the long term, as the energy bills will be much lower. 1.2 AIMS AND BROAD OBJECTIVES The aim of this project is to study alternative methods for cleaning and cooling air in Hong Kong buildings and identify the best ones for each kind of building. The technology will be analysed for its ability to replace old systems in old buildings and make the air better for less money and energy consumption. The cost of using these in new buildings will be calculated so the ROI can be computed. It is hoped that these alternative metho ds will not cost much more than the traditional methods. This makes them good to use in new buildings. The costs and savings for old buildings will also be calculated. Chapter 2: Literature Review 2.1 Methodology of Literature Review A review of the literature in peer reviewed databases was done the same search of available books on the subject. However, since the lag time for books in print is nearly a year, newer technology and more information is available in digital formats. In addition to the peer reviewed databases, common websites in the building trade, and among suppliers for the building trade, were searched for information. Finally, specialized digital databases which include technological information and sites of various authorities on the subject were also searched and sites for rating buildings, such as BREEAM, Energy Star and Green were included. The alternatives found are examined and discussed here. This project will look at all alternatives and rate them for cost, p roblems, and ROI. Even if the cost is a little bit more, the pay back time is short. If a building is expected to last fifty to a hundred years, then it pays to make it work the best possible Langston, C., & Shen, L. (2007). 2.2 Technology Modern Building Services, and many other building sites like it, has no less than five alternatives to traditional air conditioning (Energy efficient systems - modern building services ). There are many alternatives. Green water walls are beautiful, peaceful and they clean the air while cooling it too ( ). These can be use with passive solar cooling and efficient window design to keep air cool and fresh (Greenwall Australia ). Regular air conditioners drink power like hungry dinosaurs. They make a lot of noise, they do not clean the air, and they often spread mould into the building. Hong Kong buildings are some of the most inefficient in the world, since the winters are not cold. Builders did not consider that air conditioning would become a majo r expense and a major problem. Even in buildings where the temperature is comfortable. The air may not be clean. Builders can do both with simpler technology and pay less (Dauncey, 2004). Many companies even consider these
