User "friendly" residential ventilation system control strategies and effectiveness | 2003 | English
The most efficient ventilation system would only operate on demand, when ventilation was "needed".
Cavity wall is often proposed in the building envelope design as a solution for improving the thermal comfort of the inhabitants and reducing the adverse condensation effects on the building fabric.
For the building team, the design of library, archives and museum facilities brings with it special responsibilities. Archive and conservation facilities require the highest levels of preservation and maintenance of the building environment.
In recent years, poor indoor climate has caused health problems for building occupants.
Can adventitious ventilation negatively impact moisture performance of building envelopes in moderate climates ? | 2003 | English
In moderate climates, adventitious ventilation helps in keeping the water vapor balance in a building under control. This does not hold in hot and humid climates, where the outside air is a moisture source.
A manufactured home has been installed on the NIST campus for ventilation, energy andindoor air quality studies. The primary purposes of the facility are to study mechanicalventilation requirements for U.S.
Variable zone multipoint analysis in enclosure with turbulent transport properties in advanced thermal energy reduction technique | 2003 | English
Many recently developed energy-reducing strategies with respect to heat loads in residential interiorsincluded in simulation programs possess extensive capabilities in handling these loads (gains orsinks) for each zone - spatial unit designed for
Ventilation in dutch houses, a study in a representative sample of the dutch housing stock | 2003 | English
The goal of this study was the determination of the existing situation in houses with regard to air quality and energy used for ventilation in relation to the health of inhabitants.
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
