Approximatly over 90 percent of buildings in Poland are ventilated in a natural manner.
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.
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.
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.
A significant part of existing educational buildings have to be retrofit in the next years inFrance.
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
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.
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.
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.
The purpose of this study was to assess indoor air quality as well as actual ventilation in renovated school classrooms. A typical naturally ventilated school building was chosen to install different air inlet units in identical classrooms.
In recent years, the housing market in China has expanded tremendously due to economic development. Building envelopes have become more and more airtight because of improvements in building technology and concerns on energy conservation.
Our commitment to improve both air quality and energy savings in existing dwellings involves scopemeasurements campaigns.
Hybrid ventilation is one promising approach to reduce energy consumption in office buildings. On the one hand, a minimum air change rate is supplied to the rooms, even if the windows are closed.
Research has shown that highly efficient solar powered ceiling fans improve thermal comfort and potentially provide health benefits when air conditioning or conventional ceiling fans are not available, such as during the 2003 summer heat waves in
Steel truss structures, covered with a PVC thin sheet of matt light colour, were used in recent time for the construction of three new classrooms in the University of Catania (southern Italy).
Estimation of the effective fresh air supply rate on two storey dwellings employing stack effect ventilation | 2004 | English
This study deals with the ventilation performance of two storey dwellings employing stack effect ventilation to satisfy the overall ventilation requirement. The SRF (Supply Rate Fulfillment) index was used as a ventilation performance index.
