Thermal insulation in houses and sheds

Thermal insulation is usually needed for large buildings because of the requirement to comply with quality standards while for residential houses usually the builders suggest some kind of insulation. in general, the users do not know the subject and think that both heating and cooling of rooms is solved using air conditioning systems. Moreover, most people do not know how to reduce electricity bills, gas, etc. and they spend large amounts of money because they believe that is the price to pay for these services. In this paper is presented a computational tool to analyze the influence of thermal insulation on heat transfer by conduction through the roof of a certain room. The application displays the advantages of installing thermal insulation in different weather conditions in various regions of Argentina, and provides economic arguments for design and evaluation of each work.
