TM31: Building Logbook Toolkit
TM31: Building Logbook Toolkit
Note: This publication is supported by a number of supplementary files including TEMPLATES 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.
Who is it for?
The TM31 is for everyone who is or will be seeking to develop a log book including:
- Facilities managers
- Building and building services designers
- Those replacing or altering building services plant in existing buildings
- Specialist O&M manual authors who want to offer logbooks as well.
This publication is supported by a number of supplementary files that are freely available to all users. These include TEMPLATES for a standard log book and a shorter log book for small businesses - provided in Microsoft Word format. These files can be found in a ZIP folder here.
Correction Dec 2013: In the Supplementary files associated with this document, the office example has been amended to remove a reference to smoking and the meter reading pro forma has been amended to remove formula errors.

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."
