This paper deals with a pilot study in portable classrooms where neither adequate ventilation nor associated conditioning of indoor air for occupant comfort were provided. Concentrations of pollutants should be mitigated with an appropriate ventilation and should lead to a reduction of symptoms of "sick building syndrome"
This paper deals with a modeling approach that combines the classical heat and moisture balance differential equations along with the use of experimental time-series data. This approach provides an ideal form for advanced model-based control system design.
This article aims at providing an overview of recent field experience, as reported in the literature, about underfloor air distribution systems (UFAD) as an alternative to conventional air distribution.
This paper gives a description of the cleaning of metal ducts in small buildings, located in heating climates in the northern US states, with different cleaning techniques, their cost, and advices from different trade associations.
This article presents the difficulty for ASHRAE to take into account the high levels of ventilation requiries and to combine them with the demand for "guidance" encouraged by the tobacco industry and its allies.
This article focuses on the replacement air component for atrium smoke exhaust, including comparisons of three design approaches. The concepts are illustrated by case studies.
This article sums up a detailed analysis of variable air volume (VAV) box control. Sizing criteria are provided in order to minimize the life-cycle cost in typical application.
As the office environment is always changing new ways of looking at diffuser selection is mandatory.Changes in the office air delivery system may be due to new building codes/regulations, or to changing interior loads.New technologies allow innovative manners to treat heating and cooling needs. Some strategies may be used in retrofitting.
In this paper the author develops the key factors that influence the performance of ventilation systems mainly in large office buildings. Information for the efficient operation of these systems is provided.
This paper is a sum-up of the work performed by CSTB, ADEME and the Ministry of Equipement in France to improve the energy performance of the huge ministry stock of buildings (10 000 buildings of different size and uses). The objective of the project was to evaluate the performance of the buildings and to improve it in close work with the end-users.
