The value of air permeability, or the value of n50 provides important information about the impermeability of the building envelope and thus the quality of internal environment of the building. It is also one of the main evaluation criteria in classifying energy efficient buildings. Air permeability is determined by Blower Door Test where the fan blows air in or out from the measured area. The measurement is performed in a overpressure and afterwards in a underpressure during which the leaks are detected. The frame is usually placed into the front door which themselves is a weak part in the building envelope, and thus the rate of leakage completely denies. The effect of leakage of the front door is so significant that it can often cause a misclassification of the energy efficient buildings. We have tested this hypothesis by Blower Door Test on a passive timber construction build in 2007 during which we have measured the object in position of measuring device placed in the front door and the balcony door that are not encumbered by leaks caused by a security hardware and by other specific elements


Concept of sustainable buildings is defined as use of various strategy and standards of working to intensify the quality of life of occupants, secure the environment of neighborhood by lessen the construction rate of consumption of natural resources. Conventional buildings are not much conveniently rated over energy efficient buildings as per indoor climate basis, whereas when studied furthered the users have different reviews. The quality occupancy when evaluated from varying results of users has various aspects. Inappropriate use of building may concerns in bad experience in conventional buildings by the users. New area for further research could be identified as required information for an operation and use is difficult for overall quality experience of the building. There is a shortage of research that takes into account of “Unawareness” or “inconveniences” of occupancy behavior with a survey defining the authentic gap in research. Research on use of energy efficient buildings is increasing, but there is still a scope to give more information and training in operation and use. This paper justifies occupancy evaluation with indoor climate, building operation, occupancy attitudes, and economic.

Energy-efficient buildings utilise the potential of renewable sources, among which heat pumps hold an important position. As this technology has a secondary effect on the environment through its noise immission, locations of outdoor units in the exterior should be subjected to the assessment. The present article deals with the options of placing heat pumps in the exterior and the placement assessment methods. The noise burden identification through the assessment of the time exposure is presented in the example of an in situ measurement.
