The Chartered Institution of Building Services Engineers (CIBSE; pronounced 'sib-see') is an international professional engineering association based in London, England that represents building services engineers.[2] It is a full member of the Construction Industry Council,[3] and is consulted by government on matters relating to construction, engineering and sustainability.[4] It is also licensed by the Engineering Council to assess candidates for inclusion on its Register of Professional Engineers.


CIBSE was formed in 1976, and received a Royal Charter that same year following a merger of the Institution of Heating and Ventilation Engineers (founded in 1897) and the Illuminating Engineering Society (founded in 1909).[5][6] Previously CIBS,[7] the word 'Engineers' was added in 1985, and hence the Institution became CIBSE.[8]

Royal Charter

Under the CIBSE Royal Charter and By-laws, the Institution's primary objects are:

CIBSE Regulations are informed by the Royal Charter and By-laws and cover matters relating to membership, election of the board, the chief executive, and regions and divisions.


CIBSE has seven grades of membership, with the upper four granting postnominals:

Members assessed by CIBSE for professional registration may be granted the following postnominals by the Engineering Council:

Related bodies

Four societies and one institute exist within CIBSE to reflect special areas of expertise that exist within the field of building services:


Various special interest groups operate within the Institution. These are free to join either as a member or non-member.[8]



CIBSE Patrons are businesses which collaborate to give financial, technical and moral backing to initiatives led by CIBSE.


In recent years, there has been an increasing focus on sustainability and green design by the UK government. The implementation of Part L (Conservation of Fuel and Power) of the U.K. Building Regulations in 2006 led CIBSE to set up the Low Carbon Consultants Register to ensure that a body of competent and trained professionals was available to implement the various requirements of the regulations, specifically in undertaking the relevant calculations to demonstrate the required reduction in carbon emissions from buildings both in design and operation. Members of the Register must undertake specific training and examinations to demonstrate their competence in various aspects of the regulations.

The CIBSE scheme further offers accreditation as a Low Carbon Energy Assessor (LCEA), again subject to specific training and examinations, who are then able to provide the Energy Performance Certificates (EPCs) and Display Energy Certificates (DECs), as required under the Energy Performance in Buildings Regulations (EPB Regulations). These certificates can only be provided by accredited energy assessors who are members of an approved scheme such as the Low Carbon Energy Assessors Register. Furthermore, assessors are required to update their training regularly to ensure that continued high standards of competency are met.

The LCC scheme has been expanded in recent years to include for the grade of Low Carbon Consultant: Energy Management Systems, these LCC's having been trained and tested by CIBSE to ensure they have the relevant competencies to assist organisations to implement BS EN 16001.

CIBSE also offers certification for Air Conditioning Inspectors, to perform inspections as required by the Energy Performance of Buildings (Certificates and Inspections) (England and Wales) Regulations 2007.


Many training options are available through CIBSE, with the aim of providing specialised courses, conferences and seminars for those within the building services industry. and the provision of Continuing Professional Development (CPD) training, to improve and enhance the skills required to be engineering professional. Included are a range of courses from fire safety and mechanical and electrical services courses, to facilities management and business skills-focused training. Online modules can also be completed which can be used to contribute towards the Edexcel Advanced Professional Diploma in Building Services Engineering.


CIBSE publishes several guides to building services design, which include for various recommended design criteria and standards, some of which are cited within the UK building regulations and therefore form a legislative requirement for major building services works. The main guides are:

In November 2011 CIBSE made its full range of published guidance (including all the CIBSE Guides, CIBSE Commissioning Codes, Applications Manuals, Technical Memoranda, Lighting Guides) available for free to its members through the Knowledge Portal.[10]

CIBSE publishes a monthly magazine, the CIBSE Journal (formerly the Building Services Journal). Two quarterly technical journals are published in association with Sage: Building Services Engineering Research & Technology (BSERT) is free online to all CIBSE members and Lighting Research & Technology Journal (LR&T) which is free for Society of Light and Lighting members only.[11]
