CEN/STAR establishes needs for co-normative and pre-normative research in support to CEN standardization. A workshop took place in CETIAT (France) on 23-24 january 2003, its aim was to provide an overview of the trends of research and future standardization for HVAC appliances and to define the needs for pre-normative or co-normative research and interaction with standardization works.
In the UK, the pressure to improve fire prevention in catering establishments has for some years come largely from the insurance industry. Kitchen operators needed to better manage their extract ventilation systems. All cooking equipment forms a potential source of ignition. BSRIA has then compiled a document presenting a method for fire risk assessment of catering extract ventilation.
The article describes the advantages of heating designed as a system. It shows (among others) the features of balanced ventilation systems with heat recovery and compact ventilation appliances (heat recovery from ventilation exhaust air through a heat exchanger and a heat pump, to provide warm fresh air and domestic hot water).
A low energy office building in Frankfurt (Germany) with water heating/cooling from ceilings was submitted to detailed measurements during two years, in the frame of a demonstration project. Results are given showing thermal comfort and energy consumption data.
Fan is a source of noise in ventilation and air conditioning systems. The article provides information about noise emission from different types of fans and the ways to attenuate it, using different types of silencers, including passive and active silencers, or combination of both.
Thirty subjects (17 female) were exposed for 5 hours in a climate chamber to clean air at 5%, 15%, 25% and 35% RH at 22 °C, in balanced order. Another 30 subjects (15 female) were similarly exposed to air polluted by carpet and linoleum at 18, 22 and 26 °
This article shows results of air quality measurements (airborne moulds, microbes and particles) operated in summer and winter in an hospital in Japan.
In this study the performance of a double-skin façade in an office building equipped with a hybrid ventilation system was analyzed. The hybrid ventilation system studied was based on a low-pressure mechanical exhaust system and demand control of ventilati
