Building-services calculations

06 October, 2007

The second edition of BSRIA’s guide to HVAC building-services calculations has been expanded to include new and revised sections and provides practical, easy-to-follow methodologies for a range of calculations used in the design and sizing of heating, ventilating and air-conditioning systems. The guidance is mainly based on data and procedures in CIBSE Guides and other sources such as Building Regulations, with cross referencing to data sources. The guide is presented as calculation sheets — including design watchpoints, design tips and rules of thumb. It is intended to help the design process and reduce errors. Calculation sheets are presented in five sections: heating loads; cooling loads; water flow distribution; air flow distribution and acoustics. Each section is introduced using flow charts to provide an overview of system design.
