BSRIA's latest guide replaces the previous Underfloor Heating: A Designer's Guide (AG12/2001) and Underfloor heating installations: Assessment standard (AG13/2001).
The objective of this new guidance is to equip engineers with information that will help them to familiarise themselves with the basics of the technology, and to make them better able to select and apply the most suitable option.
Construction professionals such as designers, architects, structural engineers, quantity surveyors, contractors and installers will find the guide useful in helping them appreciate the services issues. Facilities managers and other professionals who are interested in the operational performance of underfloor heating, will also be interested in this guide.
The revised guide reflects the advances in the technology, design methods and applications of underfloor systems that have taken place in the last 10 years, including the growth in cooling applications and the integration of renewable energy.
Included in the new edition are chapters on cooling, energy sources, controls and floor finishes.
