The study reviewed each Code/Standard with respect to requirements relating to acommon set of ventilation factors and criteria. The main factors include the following:1.
Hockman J.L.
Passive cooling strategies require strict adherence to the physical world.
Alfini R.J.
The most efficient ventilation system would only operate on demand, when ventilation was "needed".
Raymer P.H.
This is a personal set of comments giving the author's impressions of the papers presented at the conference.
Grimsrud D.
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.
Kline W., fugate S.
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.
Aelenei L.E., Rodrigues A.M., Aelenei D.
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.
Hens H., Houvenaghel G.
In recent years, poor indoor climate has caused health problems for building occupants.
Rydholm W.
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
Hach L., Katoh Y., Murata H.
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.
Persily A., Crum J., Nabinger S., Lubliner M.
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 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.
de Gids W.
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.
Ahlander G.
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.
Temple K.A., Holton J.K.
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.
Rudd A.F., Lstiburek J.W., Ueno K.
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.
K. Guillot, P. Achard, P. Berger, A. Litvak, F.R. Carrié
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
Erhorn H., Kluttig H., Woessner S.
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.
Aelenei L.E., Rodrigues A.M., Aelenei D.
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.
James E. Blakeley, William D. Richins, Thomas K. Larson, George A. Twitchell
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.
