Implication of Infiltration on Building Energy Demand - A Review of Verification Methods

Abstract

Infiltration has a considerable impact on both, energy efficiency and occupant comfort in buildings. Due to the complexity of the analysis of this phenomenon in buildings, the verification methods are very important for its diagnostics and evaluation. In this paper, the matter of infiltration in buildings is being considered referring to both, calculation models and methods, as well as through current standards and regulations in the EU and Serbia. Different valorization methods are presented and analyzed regarding their characteristics, applicability, and complexity. Finally, preliminary infiltration measurements with a pressurization test, conducted on selected buildings of Belgrade housing stock are presented and compared with values defined by the current regulations in Serbia. Results pointed out current problems and the need for improvements regarding the treatment of infiltration in local regulations and practice.

Energy Refurbishment of Serbian School Building Stock—A Typology Tool Methodology Development

“…The research of this scope, taking into account many building types, and dealing with the entire typology, couldn't go into much detail about every aspect influencing the energy performance of buildings. However, it opens the possibility for further research of numerous topics, and as such, indoor environmental quality, infiltration rates, and the influence of ventilation on building energy performance are currently being investigated further in school buildings [23].…”
