District Heating System, Which Is More Efficient Than
Supported by ECOHEATCOOL Work package 3 Guidelines for assessing the efficiency of district heating and district cooling systems This report is published by Euroheat & Power whose aim is to inform about district heating and cooling as efficient and environmentally benign energy solutions that make use of resources that otherwise would be wasted, delivering reliable and comfortable heating and cooling in return. The present guidelines have been developed with a view to benchmarking individual systems and enabling comparison with alternative heating/cooling options. This report is the report of Ecoheatcool Work Package 3 The project is co-financed by EU Intelligent Energy Europe Programme. The project time schedule is January 2005-December 2006.

Indoor Ultrafine Particle Exposures and Home Heating Systems
Journal of Exposure Science and Environmental Epidemiology (2007) 17, 288–297 r 2007 Nature Publishing Group All rights reserved 1559-0631/07/$30.00 www.nature.com/jes Indoor ultrafine particle exposures and home heating systems: A cross-sectional survey of Canadian homes during the winter months SCOTT WEICHENTHAL, ANDRE DUFRESNE, CLAIRE INFANTE-RIVARD AND LAWRENCE JOSEPH Department of Epidemiology, Biostatistics and Occupational Health, Faculty of Medicine, McGill University, Que´bec, Canada Exposure to airborneparticulate matter has a negative effect onrespiratory health inboth childrenandadults. Ultrafineparticle (UFP) exposures a re of particular concern owing to their enhanced ability to cause oxidative stress and inflammation in the lungs. In this investigation, our objective was to examine the contribution of home heating systems (electric baseboard heaters, wood stoves, forced-air oil/natural gas furnace) to indoor UFP exposures. We conducted a cross-sectional survey in 36 homes in the cities of Montre´ al, Que´ bec, and Pembroke, Ontario. Real-time measures of indoor UFP concentrations were collected in each home for approximately 14 h, and an outdoor UFP measurement was collected outside each home before indoor sampling. A home-characteristic questionnaire was also administered, and air exchange rates were estimated using carbon dioxide as a tracer gas. Average UFP exposures of 21,594 cmÀ3 (95% confidence interval (CI): 14,014, 29,174) and 6660 cmÀ3 (95% CI: 4339, 8982) were observed for the evening (1600–2400) and overnight (2400–0800) hours, respectively. In an unadjusted comparison, overnight baseline UFP exposures were significantly greater in homes with electric baseboard heaters as compared to homes using forced-air oil or natural gas furnaces, and homes using wood stoves had significantly greater overnight baseline UFP exposures than homes using forced-air natural gas furnaces.
