This document results from a Working Group set up by the World Health Organization. It formulates a set of statements on the right to healthy indoor air.
The brochure describes the main characteristics and advantages of low temperature heating systems. It presents 8 buildings with such systems, briefly describing the building and its equipment.
This paper gives information about the design of displacement ventilation systems for telecommunication equipment rooms, which need an increasing cooling load because of higher density and new generations of telecommunication systems.
This paper discusses design issues for underfloor air distribution systems : design objectives, air distribution issues, occupants comfort issues, control of interior and perimeter zones.
The natural ventilation potential (NVP) is the possibility, or probability, to ensure anacceptable indoor air quality by natural ventilation only. A passive cooling potential (PCP)can also be defined, as the possibility to ensure an acceptable indoor thermal comfort usingnatural ventilation.
The combination of an open wet cooling tower with chilled ceilings is a CFC free, cheap and low energy cooling solution. The efficiency of this alternative to mechanical cooling is very dependent on climate. There is a need for specific tools to help designers to size the system and to estimate its energy and water consumption. A building simulation tool, called ConsoClim, has been used to predict the performance of this system for different French climatic locations, thermal inertia, internal loads and solar gains.
This paper presents the results of a field study on five HVAC duct systems in France. The principal objectives of this work were a) to evaluate the extent of duct leakage in those systems; b) to compare design and actual fan flow rates; c) to evaluate the thermal energy losses in the air ducts. The ductwork airtightness, measured by fan pressurisation method, was found to be in general well above the leakiest EUROVENT 2/2 class (class A), yielding unacceptable uncontrolled airflows. Fan airflow rates were measured with the constant injection tracer gas method.
