This title covers the design and commissioning of variable flow hydronic systems, including commissioning procedures for constant volume systems and system components and variable-flow systems.

This updated guide incorporates industry feedback from nearly twenty years of flushing and cleaning using BSRIA's Pre-Commission Cleaning of Pipework guides. It will replace our previous edition (AG 1/2001.1).

This title presents an updated manual which covers the four major aspects of the commissioning process - design requirements, installation considerations and commissioning procedures, plus information on documentation. It is intended for use in conjunction with the CIBSE Commissioning Code, Series W Water Distribution Systems.

Legionnaires' disease, a pneumonia caused by the Legionella bacterium, is the leading cause of reported waterborne disease outbreaks in the United States. Legionella occur naturally in water from many different environmental sources, but grow rapidly in the warm, stagnant conditions that can be found in engineered water systems such as cooling towers, building plumbing, and hot tubs. Humans are primarily exposed to Legionella through inhalation of contaminated aerosols into the respiratory system. Legionnaires' disease can be fatal, with between 3 and 33 percent of Legionella infections leading to death, and studies show the incidence of Legionnaires' disease in the United States increased five-fold from 2000 to 2017. Management of Legionella in Water Systems reviews the state of science on Legionella contamination of water systems, specifically the ecology and diagnosis. This report explores the process of transmission via water systems, quantification, prevention and control, and policy and training issues that affect the incidence of Legionnaires' disease. It also analyzes existing knowledge gaps and recommends research priorities moving forward.
