A Study on the Thickness of Heat Insulation Materials Based on Total Cost of the Optimal Principle

Abstract

The cost of building insulation materials in construction phase has a significant impact on its energy costs in operational phase, so that it plays a meaningful role to make the total cost of insulation material low in both phases. From the point of the selection to thickness of outer heat insulation materials, this paper, making full use of energy simulation software, is keen to study on the thickness of heat insulation materials based on optimal cost principle in perspective of whole life cycle, in case of an artitecture in a some shopping mall. With the aid of eQUEST energy smulation software, this paper tries to simulate the cost of cooling and heating technology, besides it simulates different thick insultion materials, which takes advantage of mathematical models to acquire the relationship between energy consumption and thermal insulation. At last, it can be summarised the best thickness of heat insulation materials with low cost, and it can also provide some proposed improvements for the original design through comparision.
