It has already been proved that air leakage causes a great impact in the energy performance of buildings in cold climates. In recent years, many studies have been carried out in northern Europe, US and Canada.
38th AIVC - 6th TightVent - 4th venticool Conference - Nottingham, UK - 13-14 September 2017
The 38th AIVC Conference "Ventilating healthy low-energy buildings", was held in Nottingham, UK, 13-14 September 2017. Contains 113 papers and summaries.
Methodology for the characterization of the envelope airtightness of the existing housing stock in Spain | 2017 | English | 10 pp
Experimental and Numerical Investigation of Air Distribution in a Large Space | 2017 | English | 10 pp
A literature review has revealed that there is a very limited number of numerical or experimental studies of the air flow for mechanically ventilated large occupied rooms.
An airtight building envelope ensures not only the energy-efficiency of a building, but also a damage free construction. Important to achieve optimal airtightness are the planning, implementation and materials.
Heatwaves are often responsible for many deaths due to high temperature indoors. Energy savings is a key element in building design and refurbishment works to reduce the impact of climate change.
Durability of building airtightness, review and analysis of existing studies | 2017 | English | 14 pp
Mandatory building airtightness testing has come gradually into force in European countries mostly because of the increasing weight of building leakage energy impact on the overall energy performance of low-energy buildings.
Demand controlled ventilation in school and office buildings: lessons learnt from case studies | 2017 | English | 9 pp
Demand controlled ventilation (DCV) refers to a ventilation system with air flow rates that are controlled based on a measurement of an indoor air quality (IAQ) and/or thermal comfort parameter.
Design and operation of ventilation in low energy residences – A survey on code requirements and building reality from six European countries and China | 2017 | English | 10 pp
One of the key objectives of the IEA Annex 68 research programme entitled “Indoor Air Quality Design and Control in Low Energy Residential Buildings” is to provide a generic guideline for the design and operation of ventilation in residential buil
There are several methods for measuring air tightness that may result in different values and sometimes quite different uncertainties.
Assessment of the durability of the airtightness of building elements via laboratory tests | 2017 | English | 2 pp
The airtightness just after the end of a building phase is assumed to be relevant criteria for high energy performance.
Statistics, analysis and conclusions from 250,000 blower door tests, including ventilation types | 2017 | English | 8 pp
With lower air leakage in modern homes, ventilation of homes has become more important than ever before. It seems however that we are getting it very wrong.
The industry is now focusing in system solutions and the goal is to be able to deliver complete reliable, energy efficient solutions that is understandable and easy to maintain by the normal service personal.
Air infiltration holds a central role in building energy consumption and is associated to several building physics phenomena.
Natural Pressure Differential – Infiltration Through Wind Results of a Long-Term Measurement | 2017 | English | 12 pp
Wind pressure and thermal forces are driving forces for pressure difference on the building envelope.
