Simulations of indoor air quality and ventilation impacts of demand controlled ventilation in commercial and institutional buildings | 2003 | English
Carbon-dioxide (CO2) based demand controlled ventilation (DCV) offers the potential for moreenergy efficient building ventilation compared with constant ventilation rates based on designoccupancy.
The airflows through a one family prototype building have been simulated. Supply openings in living room and bedrooms have a size of 200 and 400 cm2 respectively.
Residential dehumidification and ventilation systems research for hot-humid climates | 2003 | English
Twenty homes were tested and monitored in Houston, Texas, U.S.A. to evaluate humidity controlperformance and operating cost of six different integrated dehumidification and ventilation systems that could be applied by production homebuilders.
A concept is investigated for the energy efficient control of residential mechanical ventilation in response to outdoor air temperature and the corresponding stack-driven infiltration.
Field characterization of the envelope leakage of houses for determining rehabilitation priorities | 2003 | English
This paper presents the results of a field study conducted on 8 houses (out of a set of 31) owned and managed by a French social housing public leasing company.
Analysis of a ventilated residential building by means of an air based radiative cooling system | 2003 | English
The thermal performance of a monozone building located in Lisbon is studied when night ventilation combined with radiative cooling is used in order to remove the heat from indoors.
IEA ECBCS Annex 36 : Energy Concept Adviser for Technical Retrofit Measures - An internet-based Tool on Information, Assessment and Concept Development of Energy-saving Retrofit Strategies | 2003 | English
Research partners of 10 different countries are developing a computer tool in the framework of IEA ECBCS Annex 36, which helps decision makers to include the most energy-efficient and economic technical retrofit measures into the retrofit of their
Ventilation, Humidity Control and Energy : A Tightrope of Challenges and Opportunities | 2003 | English
This paper is a keynote address presented at Ventilation, Humidity Control and Energy 24th AIVC Conference.It is a warning for HVAC professionals that are however walking a tightrope.
Single- and double-section manufactured homes were instrumented in 2001-2003 to measure continuous energy usage and air infiltration with respect to the environmental conditions of a windy cold dry climate.
Simplified measurement techniques for health visitors to assess indoor environments | 2003 | English
There is research acknowledging that the home environment may be responsible for worsening respiratory conditions, especially for children. The indoor environment is a substantial source of exposure to pollutants e.g. environmental tobacco smoke.
Developing virtual laboratories for the design and test of ventilation control strategies | 2003 | English
The control industry integrates more and more recent innovations, especially on the sector of communication networks (bus), control (fuzzy logic, neural networks...) and informatics (hard-and software) for the development of Building Automation an
Reshyvent - A EU cluster project on demand controlled hybrid ventilation for residential buildings | 2003 | English
In January 2002 the EU RESHYVENT project started, a three-year project within the EU Fifth Framework Programme on the investigation and development of demand controlled hybrid ventilation systems in residential buildings.
Experimentation : humidity controlled system in french collective buildings refurbishment | 2003 | English
In France, most of the public project managers have collective dwellings built in the 70’s 80’s with first generation mechanical ventilation systems.
Impact of residential natural ventilation and air-tightness techniques on the energy loss and indoor air quality | 2003 | English
To better quantify the impact of different window opening models in comparison to ventilation techniques a multizone ventilation model, incorporating the CO2-production of the inhabitants, was developed, using Comis-Transys.
For historical and demographical reasons, in many European countries, an important part of educational building must be retrofitted.
In order to facilitate nationwide analysis of ventilation and indoor air quality issues in residential buildings, a set of homes has been defined to represent the housing stock of the United States.
Assessment and description of humidity controlled system in french residential buildings | 2003 | English
In France, ventilation in new residential buildings must be designed and dimensioned according to the Health regulation (Arrêté du 24 mars 1982) which is basically based on required extract air flow rates.
The airtightness of a building envelope impacts upon the magnitude of uncontrolled air leakage and associated ventilation energy losses. A building's airtightness can be assessed using a steady state fan pressurisation technique.
Passive cooling strategies require strict adherence to the physical world.
