The article describes the influence of the supply air devices that are part of hybrid ventilation system which is being developed within a EU funded project RESHYVENT as a part of this project, on thermal comfort in living-room of a three-bedroom
Demand controlled ventilation applicable for any air tightness level and occupancy ? | 2004 | English
The Dutch housing stock consists for about 70% of single family houses with an average N50 of about 7-9 ACH and for 30% of apartments with an average N50 of about 3-4 ACH.New single family houses are much more airtight.
The Minimum Ventilation Rate standard for dwellings is essential not only to provide occupant health and comfort, but also to remove and dilute the dominant pollutants.
Major ventilation developments covering systems, measurements and design methods have taken place over the last 25 years. Our understanding about the impact of ventilation on the indoor environment and energy use has also evolved.
School buildings in Flanders are quite old. They cause concern not only about energy efficiency but also about thermal comfort, indoor air quality, speech intelligibility and visual comfort.
Natural ventilation of residential buildings in protuguese winter climatic conditions | 2004 | English
In this paper, the current situation of Portuguese residential buildings in terms of ventilation systems ispresented.
This paper presents ventilation systems with longitudinal counterflow spiral recuperators. Heat transfer losses in ventilation system can be reduced by increasing the length of the recuperator, but in this case pressure drops increase.
The Sint-Pieterschurch in the city of Ghent is one of the largest churches of the city. It was built in the 17th century.
For retrofitting of existing dwellings MVHR is seldom applied, despite the potential in energy saving and improving thermal comfort and indoor air quality.
Approximatly over 90 percent of buildings in Poland are ventilated in a natural manner.
Setting up a database of indoor climate measurements in recently built Belgian dwellings | 2004 | English
One of the major sources of problems in dwellings -if not the main source- is moisture, especially due to surface and interstitial condensation on walls and roofs.
Introduction to integration of renewable energy in demand controlled hybrid ventilation systems for residential buildings | 2004 | English
In the scope of the EU supported project RESHYVENT, the possible integration of Renewable Energy Solutions (RES) into hybrid ventilation systems has been analysed.
Local control of ventilation in large buildings is considered to be a main issue in energy savings regarding the huge energy losses that are usually induced by such large volumes.
Energetic effects of demand - controlled ventilation retrofitting in a biochemical laboratory building | 2004 | English
The main objective of the demonstration project LabSan is the innovative energetic retrofitting of a research laboratory building (3724 m² net floor area) which can serve as an outstanding and guiding example for a large number of existing laborat
A significant part of existing educational buildings have to be retrofit in the next years inFrance.
Impact of ventilation systems on indoor air quality and annual energy consumption in school buildings | 2004 | English
The paper presents the results of the analysis of the impact of various ventilation systems on indoor air quality and energy consumption, performed for a typical Polish elementary school that was built in 1970s.
The aim of the project is to study, develop, build (prototype system) and evaluate an energy efficient demand controlled hybrid ventilation system for dwellings in a cold climate.
Blower door tests (EN 13829) for quality assurance : getting air-tight buildings in retroffiting, too | 2004 | English
For retrofitting as well as for new buildings a good airtightness is an important issue.
In-situ performances measurement of an innovative hybrid ventilation system in collective housing retrofitting | 2004 | English
To get closer from comfort and energy levels of new buildings conciliating economical viability for the big retrofitting market : the challenge opens the way to the most innovative ventilation systems.
