The improvement of energy efficiency and environmental performance of buildings is considered a matter of high priority worldwide. For this reason, energy-efficient technologies are being increasingly implemented in all sectors. This article provides an overview of integrated building design process that is crucial in order to better integrate the activities required to accomplish the design of low-energy buildings. Design of energy efficient buildings is a process that requires a wide knowledge of the principles of energy efficient building design, material selection and installation, the application of building automation, analysis of the building physics and analysis of indoor comfort. This article shows the importance of an integrated design of energy-efficient buildings in light of the new requirements that will need to be met by the architects and engineers specializing in this area. It also present...

The standards describing how to ensure comfort were created in times when the challenges of building ZEB/NZEB were not yet explored and energy issues were not as important as they are today. Therefore, the assessment of the thermal and climatic comfort of people living and working in such buildings requires a new or revised approach to the methodology of thermal comfort assessment. In this article, the authors present the results of a thermal comfort study based on measurements and thermal sensory tests. Testing was carried out in an experimental office building (passive standard). The main goal of the experiment was to compare the thermal comfort measurement method based on the ISO-Fanger model with the actual comfort results obtained by the panellists in the model office condition. ...

In this process, one discovered some drawbacks such as possible entry of radon gas or high humidity in the shoulder seasons. Elsewhere, we highlighted that when the outdoor temperature changes frequently, one needs using two different air intake sources with an automatic selection of the one more appropriate for the actual weather conditions. In winter, the EAHX may be used continually but in the other seasons, the selection should be performed by a steering/ control system. In this paper examined two nearly identical EAHX systems placed in the soil next to the building or under the basement slab. While there is an advantage in the under house placement, yet the advent of integrated system design permits replacing the EAHX by different heat exchangers located in the mechanical room (as it was done in a case study in NY) or in the exterior wall. In the latter case we propos...
