The current legislative standards require as much as possible energy efficient construction. Airtightness is a key component of energy-efficient buildings. Airtightness is characterized by air leakage through the building envelopes. Untightness leads to uncontrolled air exchange and increased heat loss. Using the exploratory analysis of variables is analyzed the state of the airtightness of energy-efficient buildings in the United Kingdoms in recent years. The source of data sample set on the airtightness of UK en...

At present, the building sector holds more than 40% of energy consumption and 36% production of greenhouse gas emissions. The whole sector of buildings uses more than 50% of the Earth's raw materials and produces approximately 50% of world waste. The current legislative standards require as much as possible energy efficient construction. The inadequate thermal performance of the buildings and are currently the biggest challenges for the sector of buildings in the European Union in the context of addressing the sus...

People spend approximately 90% of their life in the indoor environment of buildings. Indoor environment significantly influences the health, the comfort and the performance of buildings users. The long-term insufficient indoor environment is associated with the Sick Building Syndrome (SBS). According to previous studies, basic factors influencing satisfaction and performance in indoor environments include indoor air quality and ventilation, thermal comfort, lighting and daylighting, noise and acoustics, space layo...

Synergic effect of the individual components of the indoor environment is considered to be a significant determinant of the quality of the indoor environment. The quality of the indoor environment affects not only the user's comfort but also the health of the users of the buildings. The main objective of the paper is to confirm or exclude a statistically significant impact of hygro-thermal conditions on the indoor air quality (IAQ). Hygrothermal conditions and indoor air quality are the essential components of the...
