Examination of the thermal performances resulting from energy efficient desing of public buildings

A large amount of energy needed in the world is derived from fossil-based sources. The energy need and demand in our world where the population rapidly increases, also increase at a great pace. Unfortunately, it is estimated that this increasing demand will not be met with the existing world energy reserves in the near future. As is the case in the world, the energy demand in our developing country also increases day by day. However, as our country suffer from scarce fossil fuel resources, efficient and effective energy use comes to the forefront. A large part of the energy consumed in our country (25%) is used for heating purposes in buildings, because thermal insulation in buildings is either never done or made inadequately. It is clear that a considerable amount of energy can be saved if insulation practices are applied in buildings duly and sufficiently. In the present study, the uninsulated and insulated conditions of a public building in Gümüşhane province were analyzed, and the time period for paying off the initial investment cost of the building insulation was calculated. Then, the relevant energy identity documents were issued. In addition, the heat transfer analysis was performed for the uninsulated and insulated conditions of the outer walls of fifteen public buildings using the Ansys-Fluent program. Moreover, the heat distributions formed on exterior surfaces in the uninsulated and insulated conditions of thirty-three public buildings were analyzed comparatively taking thermal camera images.
