From January 1st 2013 on, the French energy performance regulation will demand that the airtightness level is justified and that airtightness of a…
The efficiency of air-to-air heat recovery ventilation units is of great importance for EP calculations (energy performance of buildings) throughout Europe…
DIN 4108-7 requires a limit of q50 ≤ 3.0 m³/m²h for the air permeability of large buildings. Even stricter limits with respect to q50 can be found at DGNB […
The aim of this paper is to investigate the influence of the selective ventilation in the thermal performance of modern naturally-ventilated houses…
Reliable airtightness data is needed to calculate the estimate of air infiltration and the thermal loads for building energy efficiency and indoor comfort.…
Natural ventilation is increasingly considered a promising solution to improve thermal comfort in buildings, including schools. However in order to support…
Air quality in offices depends on the ventilation system ability to remove contaminants from the occupied zone. In a low polluted building air quality…
Despite a lot of Integrated Design Process guidelines and procedures have been developed in the last few years, more specific energy design procedures are…
This article deals with summer comfort and room air distribution in low-energy housings. In such buildings, the efficient thermal insulation and air…
Diffuse ceiling ventilation is a novel air distribution device that combines the suspended acoustic ceiling with ventilation supply. A diffuse ceiling…
The stock housing of England (UK) constitutes the oldest housing stocks in the world. Indeed, 63 per cent of all dwellings were built before 1960s and thus…
by space and water heating. The high costs of energy are a national matter not only for their economic and environmental implications, but also because they…
French standard for airtightness measurements is NF EN 13829. It is completed by French application guide GA P50-784, to set calibration rules more…
In France, starting January 1st, 2013, the energy performance regulation will impose an airtightness treatment for every new residential building. This…
The energy consumption needed for establishing a good indoor climate in shopping centres is often very high due to high internal heat loads from lighting…
Hybrid ventilation (HV), as a combination of automated natural ventilation (NV) and balanced mechanical ventilation (MV), provides opportunities to use the…
The UK Government strategy for all new homes to be built to zero carbon standards by 2016 is based upon a “fabric first” approach to design. This means…
BR10 requires that all new residential constructions should be built as low energy housing. In order to meet these requirements residential buildings must…
The objective of this study was to develop a method for hourly calculation of the operating temperature in order to evaluate summer comfort in dwellings to…
Sizing rules in residential ventilation standards lack uniformity in both methodology and resulting design flow rates. Additionally, mere comparison of…
