LoginIn 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.

Can adventitious ventilation negatively impact moisture performance of building envelopes in moderate climates ? | 2003 | English
In recent years, poor indoor climate has caused health problems for building occupants.
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
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.
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.
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.
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.
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.
Increasing emphasis on energy-efficiency has many jurisdictions enacting stricter energy codes.
For energy savings, DCV systems are more and more used in ventilation systems but toestimate their energy savings, variation of occupation in the building (in time and number ofperson) must be estimated.
The building envelope is primarily an environmental separator, which allows indoor spaces to bemaintained at different conditions from the outside environment.
The knowledge of indoor air humidity in the design phase is important to decide on the appropriate moisture control measures to prevent moisture problems in building components.
In France, in non residential buildings, these systems are generally controlled by either a CO2 sensor or optical movement detection (infrared).The part of the study we present here was to determine :- laboratory tests methods to assess the perfor
In highly insulated residential buildings, complying with the Passive House Standard, the space heat demand can be covered by air heating at air flow rates given by air quality requirements, without the need for additional air re-circulation or fo
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.
