Residential dehumidification and ventilation systems research for hot-humid climates | 2003 | English
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
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.
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.
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
IEA ECBCS Annex 36 : retrofitting in educational buildings - REDUCE 25 case study reports from 10 different countries | 2003 | English
The IEA ECBCS Annex 36 deals with the energy retrofit of educational buildings.
An evaluation of natural ventilation and comfort of a multi-storey university office building | 2003 | English
Ventilation and comfort assessment of buildings is not a new practice in post occupancy evaluation (POE) of buildings.
Effective weather resistive barriers (WRB) perform important functions in retarding waterentry into walls and in controlling water vapor movement as well as the amount of energyattributed to air leakage (Burnett, 2000; Weston et al 2001).
The Norwegian Building Research Institute (NBI) has completed a study of the performance of balanced residential ventilation systems with heat recovery (HRVs) in Norway.
The use of natural ventilation systems continues to be a popular feature in low energy, sustainable building design.
Findings about sick building syndrome in Sydney’s offices are presented. The aim is to ascertain whether perceptions of sick building syndrome in offices impact on discrete aspects of workplace performance and management.
Economically optimal dimensioning of a counterflow and crossflow heat exchanger for free cooling | 2003 | English
During the cold seasons, it is possible to use ambient air to cool down the coolants in air-conditioning or other refrigeration applications. Applying this free cooling reduces the energy costs of a refrigeration machine.
In the survey study ‘Kantoor 2000’ the HVAC-system of several large office buildings in Flanders was monitored. Some of these buildings use air humidity control, most of them not. This triggered the question : why?
Mold in dwellings is a persisting complaint in moderate climates.
For energy savings, DCV systems are more and more used in ventilation systems. In France, in nonresidential buildings, these systems are generally controlled by either a CO2 sensor, or an opticalmovement detection (infrared).
A Demand Controlled Hybrid Ventilation System is a two-mode system using natural forces as long as possible and electric fans only if necessary.
