Winter Operation of Air Conditioning Systems in New Office Buildings

19.6.2017 | Ing. Miloš Lain, Ph.D. | Vytápění větrání instalace 3-2016
The article deals with thermal balance of the administrative building during winter operation. It refers to the fact that for the existing administrative buildings the internal heat gains are often higher than the overall losses by heat transfer. The balance includes the influence of ventilation and heat recovery. The study is supplemented with detailed hourly analysis. The article discusses the conceptual solution for heating, ventilation and cooling of such buildings in winter. The article is also accompanied by actual experience with winter operation of selected buildings.

What are the common parts of residential buildings in the Czech Republic?

19.6.2017 | Ing. Petr Bohuslávek, redakce
The definition of what is a common part of a residential building is essential especially when modifying the building structures and eliminating defects that affect both a common part and residential units. How common parts are defined affects who finances the modifications and reconstructions of such structures and parts. The definition of common parts is based on the new Civil Code (No. 89/2012 Coll.) and on the already abolished Act on Ownership of Housing (No. 72/1994 Coll.).
