Building failures related to moisture, ventilation and energy issues could be avoided if there were fewer misunderstandings and more knowledge between the different actors involved in the building process over the importance of building physics. Ignoring building physics principles during the design and construction phases can lead to a number of problems during the operation phase such high energy usage, health problems, physical building damage and a host of other problems related to these.

This paper aims to show the problem arises due to the sick building and the solution to come out of this sick building. Keywords: airtightness, heat insulation, moisture transfer, sick building I. INTRODUCTION Building physics is the science of how energy interacts with the materials within a building envelope. It encompasses the fields of heat transfer, moisture transfer and air flows. This means that building physics can include other areas such as energy efficiency, indoor air quality, mould in buildings, ventilation systems etc. Building physics is originates from the three application oriented disciplines: applied physics, building services and building construction. Already in the 20th century, some circle of the physicist showed a lot interest in the application of the noise control to building construction. Building Physics is bound by the necessities of the building, which means the creation of the indoor environment which protect human being against unexpected changes in the climate. As a consequences, the separation between the inside and outside i.e. the envelope of the building (floor, facade, roof) is submitted to the numerous climatology loads and climate differences. An appropriate envelope design along with the appropriate detailing will reduce the effects of external climatology loads. Appropriate building envelope design will minimize the consumption of energy and also improve the indoor environment.
