Future climatic effect on building refurbishment using ventilation for cooling: A case study | 2011 | English
This paper deals with air-soil heat exchangers used for heating or cooling airflows used for ventilation of buildings.
Quality Management Approach to Improve Buildings Airtightness Requirements and Verification | 2011 | English
In France, starting on January 1st, 2013, a minimum airtightness value for all residential building will be required by the energy performance regulation (RT 2012).
Through the experiences gained by building a sufficient number of air-tight buildings, the author will illustrate the ease of detailing and constructing an air tight building. Using parallels to conventional building typologies, the methods of mak
At the end of 2010, two manufacturers have commissioned an independent engineering firm to carry out a cost-benefit analysis of air-tightness in ventilation.
Demand-controlled ventilation: An outline of assessment methods and simulation tools | 2011 | English
Enhancing the energy efficiency of buildings imposed by global warming and by the perspective of fossil fuel dwindling requires new technical solutions, more efficient.
The thrust of airtightness specification and testing is derived from energy considerations.
During the recent decades, energy consumption of buildings, together with the costs for operation, has gained increasing concern. HVAC systems stand for a significant share of the total energy consumption in buildings.
The use of a sampling method for airtightness measurement of multifamily residential buildings - An example | 2011 | English
Large buildings can not always be tested as a single pressure zone.
The improvement of energy efficiency is the key issue after the energy performance of buildings directive came into the force in European Union countries.
Method to assess the performance of ventilation systems in dwellings considering the influence of uncertainties | 2011 | English
Normally, the design of a ventilation system in a dwelling is based on national regulations, related design rules, building tradition and general knowledge about healthy indoor air quality, ventilation and air handling units.
Whole year simulation of humidity based demand controlled hybrid ventilation in multiapartment building | 2011 | English
The paper presents the whole year simulation of humidity based demand controlled hybrid ventilation in multiapartment building.
Control and performance of innovative ventilation systems in low energy buildings: A studied case | 2011 | English
As part of a project aiming at assessing ventilation in low energy buildings, this study analyses the performance of innovative ventilation systems used in a single-family building.
Behavior of leakages exposed to dynamic wind loads. A numerical study using CDF on a single zone model | 2011 | English
Wind is a potential dominant factor regarding the air infiltration through building envelopes. Due to its dynamic characteristics, quite complex aerodynamic phenomena arise around a structure or through cracks and openings.
Ventilation rates and indoor air humidity depending on local climate – simulations and measurements of 9 European countries | 2011 | English
Most European standards and national regulations about ventilation rates are based on indoor air quality assumptions in terms of contamination. On the other hand, indoor air humidity is important for human health as well.
A study of excessive air leakage in the ductwork of a large pharmaceutical plant located in the Southeast United States is executed in order to determine the energy loss associated with the excessive ductwork leakage.
The feasibility of good air-tightness in new buildings can be determined based on the obtained air tightness classes as defined in EN 12237.
Hands-on training courses for ventilation system installers within the Praxibat initiative | 2011 | English
This paper gives a quick overview of the PRAXIBAT programme led by the French Agency for Energy and Environment to improve building professionals skills to achieve low- or nearly zero-energy buildings.
Portugal introduced, for the first time, in the 2006 Building Regulations, a requirement on the airtightness of the ductwork in new HVAC installations. A test is required during commissioning.
This paper presents some results from the Work Package 5 in the HealthVent project supported by the European Commission.
