The recent changes in the developed nation’s means that the results of performance review are backed by legislation. TM22 and the accompanying software provide assistance to the review requirements. Though its core purpose is to evaluate energy efficiency, the process could be of use for key energy stakeholders. This results in effective building management.
The energy analysis tool TM22 has for a long time delivered a systematic framework for initiating an energy survey, along with documenting the outcomes. The advanced version of the tool enables a building’s energy usage to be determined to a large extent, while there exists an opportunity to use sub meter information and various benchmarks. For e.g.: Technical Memorandum 22 is a very effective tool for results

If a DEC is unavailable, benchmarks from CIBSE TM46 can be utilized. On the other hand, they are median benchmarks that would have to be revamped to be in line with the building requirements.
• User-determined benchmark data can be achieved based on a property portfolio of energy assessment. A transparent evaluation is restricted to one worksheet, which accumulates simple data related to the building which includes floor size, energy usage, input/output energy of CHP. This would be enough to benchmark the energy usage and carbon dioxide emissions.
• Again, it delivers an understanding of the building’s energy effectiveness, since the output of renewable origins is a part of the specified building energy use segment. The overall energy consumption is allocated with regards to 20 end-use groups. In this, fifteen are designated before hand, while five are stated by the user, which includes six authorized DEC separable energy
