TM31: Building Logbook Toolkit
Note: This publication is supported by a number of supplementary files that are freely available to CIBSE members and non-members here.
Part L 2006 requires that building owners be provided with summary information about a new or refurbished building, its building services and their maintenance requirements in a building log book. CIBSE TM31 explains what sort of information the log book should contain.
The CIBSE Building log book tool kit templates offer a standard format for the summary. This covers how a building is intended to work and how it is meant to be maintained and serviced. They also provide a means to record the energy use and maintenance of the services within the building.
Log books provide a simple, easily accessible summary of a new or refurbished building rather than the detail contained in O & M manuals. The easy way to show compliance with new Part L is to produce a building log book based on the template and guidance in CIBSE TM31. It gives detailed guidance on the scope, structure and contents of the log book, who should write it and who should keep it up to date. The CD-ROM includes standard templates and worked examples. For hard copy, copy purchasers note that this means that VAT is applied to the purchase price of this title.

Roy Kirkham of NG Bailey made the following useful comments in April 2014 on the Supplemenatry files:
"I just downloaded your very helpful TM31 Zip file for completing building log books. There are two things I think you should know about that I noticed after a quick look around them. Firstly, in the 'Office' example of a log book, on page 12 there is a statement about increased ventilation being required if smoking were allowed in the building, which is now no longer legal.
Also, on the meter reading excel proforma, there ia a formula error in cells D15, F15, H15 & J15.
Otherwise a fantastic tool kit, thank you."
