This report describes the characteristics of a thermodynamic concept, exergy, in association with building heating and cooling systems. It introduces the various forms of exergy and the mathematical formulations used to evaluate them. It gives an example of exergy calculation for space heating systems.

This booklet summarizes the work of IEA ECBCS Annex 35 'Hybrid ventilation in new and retrofitted office buildings' and is based on the research findings from the participating countries. It describes the principles of hybrid ventilation technologies, control strategies and algorithms, as well as analysis method. The 13 case studies include both new-built and retrofitted designs. The booklet is accompanied by 21 technical reports and 13 case study reports from various authors.

Describes two European research projects on performance criteria for healthy buildings in which TNO Building and Construction Research (The Netherlands) is involved : HOPE (Health optimisation protocol for energy efficient buildings : Prenormative and socio-economic research to create healthy and energy efficient buildings) and PeBBu (Performance based building Thematic Network).

Ventilation, air conditioning and air heating systems are of vital importance for the health and comfort of residents and other building users. However, there exists a substantial body of literature that shows that HVAC systems performance can be greatly affected by inferior quality ductwork. To avoid these problems, it is important to pay greater attention to the design, construction, installation, and maintenance of ductwork systems, bearing in mind that the primary functions of the HVAC systems must be fulfilled.

Pressure loss coefficients were measured for several flat oval tee and lateral fittings. The paper gives measurement results and pressure loss curves.

Descibes an inter-laboratory comparison between 18 labs from 10 European countries to improve the procedure used to measure VOC emitted from samples of building materials and products in small test chambers.

The document consists in the Proceedings of the 2001 AIVC conference, which took place in in September 2001 in Bath (England). It contains 42 articles corresponding to the speeches given during the Conference.

The document consists in the Proceedings of the 1999 AIVC conference, which took place in in August 1999 in Edinburgh (Scotland). It contains 141 articles corresponding to the speeches given during the Conference.

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.
