Discusses the new concept of hybrid ventilation, and the objectives of IEA ECBCS Annex 35 research in this area. Important areas of research are the development of control strategies, theoretical and experimental studies, the development of a decision tool, the implementation and demonstration of hybrid ventilation, reporting and expected results.
In order to ensure that buildings and HVAC plans are truly for people and actually satisfy the occupants, it is necessary to obtain feedback from the occupants. This can be done by a novel questionnaire that produces a readily understandable fingerprint a
Work carried out in the UK, on behalf of, and fully funded by the Department Transport and Regions, has produced guidelines for the cost effective refurbishment of offices for natural and low energy ventilation. The aim of the work is to counteract the current trend towards the installation of air conditioning when other low energy strategies will provide suitable comfort conditions. This paper shows ways in which comfort conditions can be achieved with zero or minimal energy use in a range of office types, using natural ventilation or simple mechanical low energy systems.
