LoginFor 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).

Mold in dwellings is a persisting complaint in moderate climates.
A Demand Controlled Hybrid Ventilation System is a two-mode system using natural forces as long as possible and electric fans only if necessary.
Natural night ventilation and an earth-to-air heat exchanger are applied in the low-energy office building ‘SD Worx’ in Kortrijk (Belgium).
An experimental campaign was organized during the summer period 2002 in Athens, in the framework of the European RESHYVENT Project.
Infiltration has traditionally been assumed to contribute to the energy load of a building by an amount equal to the product of the infiltration flow rate and the enthalpy difference between inside and outside.
This paper deals with the real behavior of a humidity controlled air inlet, regarding to relative humidity and temperature.
In Arctic and sub-Arctic climates, such as those in Scandinavia, multiple-glazing windows that consist of at least three panes are widely used.
Building envelope, duct leakage and HVAC system performance in HUD-code manufactured homes | 2003 | English
Between 200,000 to 300,000 manufactured homes are built to the US Department of Housing and Urban Development’s Manufactured Home Construction and Safety Standards (MHCSS) in the US each year.
The peak electrical demand of office building VAV systems will be reduced by about 1.2 Kw/1000 Ft2 by employing an Integrated Systems Demand Control Technology (ISDCT) sequence to reduce peak intake flow by about 56%.Supply, return, and exhaust fa
In the 1990's, concern about global warming has resulted in a resurgence of interest in naturally ventilated offices. The Belgian climate is particularly well adapted to apply cooling by natural ventilation.
During the last 20 years, the humidity sensitive ventilation system evolved to products increasingly simplified thus standardised.
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.
Increasing emphasis on energy-efficiency has many jurisdictions enacting stricter energy codes.
The building envelope is primarily an environmental separator, which allows indoor spaces to bemaintained at different conditions from the outside environment.
Over the past decade, there has been extreme media attention to issues about mold and allegedlyadverse effects.
