LoginDescribes low energy houses which have been built at Lindas in Sweden. A traditional heating system has been replaced in the design by heat exchanger in combination with an exceptionally well insulated construction.
Bibliographic database Airbase
AIRBASE is the Bibliographic Database of the AIVC. It contains publications and abstracts of articles related to energy efficient ventilation. Where possible, sufficient detail is supplied in the bibliographic details for users to trace and order the material via their own libraries. Topics include: ventilation strategies, design and retrofit methods, calculation techniques, standards and regulations, measurement methods, indoor air quality and energy implications etc. Entries are based on articles and reports published in journals, internal publications and research reports, produced both by university departments and by building research institutions throughout the world. AIRBASE has grown and evolved over many years (1979 to present day, over 22000 references and 16000 documents available online). For most of the references, the full document is also available online.
Access to the publications is free of charge.
Nightsky, an innovative night roof spray storage cooling system, provides chilled water to in-slab tubing and fan coils. Passive cooling delivery from the slab cools the building in parallel with the 'active' chilled-water fan coils.
To ensure good indoor air quality in buildings, filters are installed in the ventilation ducts. These filters cause a pressure drop in the ducts, so that increased power to the ventilation fans is required to maintain the flow of fresh air.
Describes a cooling design using ground water to prevent overheating in London's underground train network. More conventional air conditioning is unusable because of the problem of exhausting the excess heat.
The brief for this university campus design required a low energy building for the business school and the education faculty, with a wide variety of room sizes and functions.
States that the poor indoor air quality of US schools has become a real concern for students, parents and educators. This article discusses why the problem exists.
By now hybrid ventilation systems are being used successfully in many projects. Three projects will be used to create a picture of the way in which the hybrid ventilation system has been used and of the experience with it.
Hybrid ventilation systems may consist of a combination of natural ventilation for air supply and a mechanical exhaust system. The quality level of thermal comfort is influenced by e.g.
When natural ventilation is being used, the quality of the air inside a building depends on the quality of the outside air. What is the outside air quality trend in the urban environment and what are the forecasts for the future?
Discusses some of the many myths of energy efficient behaviour, and the importance of scepticism and awareness.
Discusses the importance of selling the cost benefit of tight building practices in the absence of national or local codes or regulations to mandate well-sealed apartment buildings.
Describes how home performance contractors in New York are able to partner up to benefit from the US Energy Star program.
The Hong Kong Environmental Protection Department has recently launched a set of guidance notes on indoor air quality (IAQ) management for offices and public places.
This paper presents a Chinese approach to ventilation and air conditioning, which are important measures needed to improve the indoor air environment of a building.
