OR Toolkit

OR Toolkit (Operational Rating Toolkit) is a third-party software developed by SystemsLink to enable energy assessors to produce Display Energy Certificates (DECs) and Advisory Reports (ARs). OR Toolkit helps Public Building Assessors to provide clear advice on energy savings measures for public buildings. SystemsLink have provided OR Toolkit for use by members of Stroma Certification's DEC Certification scheme for Public Building Assessors.

Prospective members will be supported throughout the course of your membership with regular auditing and technical review of your public building lodgements. A further scheme requirement is the maintenance of your professional skillset through the completion of 10 hours CPD. Stroma Certification offers regular CPD material including technical bulletins to support you.
Display Energy Certificates provide public buildings with an operational rating, in terms of energy usage, on a scale of A – G (A being the most efficient). DECs are based on the actual amount of metered energy used by the building over a 12-month period. Both a DEC and an Advisory Report are required for public buildings with a useable floor area over 1,000m2, occupied in whole, or in part, by public authorities and by institutions providing public services to a large number of persons and if they are frequently visited by members of the public. The Advisory Report outlines ways in which energy can be saved and provides recommendations that include the short, medium and long-term paybacks of various green technologies. The implementation of these recommendations would reduce the building's CO2 emissions, as well as fuel costs.
