Energy Auditing (Single Building or Portfolio)

Energy Audit:

What’s an energy audit?

An energy audit is an analysis of energy flows and conservation in an existing building. It will include a series of recommendations that will reduce the energy input of a building without negatively affecting the output. It is always the first step in reducing energy expense and carbon footprint for a development.

Why would I need one?

To save money. Not only can an audit save expenditure on the usual day-to-day utility bills but it can also save money on the development carbon footprint which will reduce taxes and significantly contribute towards future-proofing your asset.

How do you perform an audit?

We would visit your site and survey the buildings energy-consuming end uses, mainly lighting and heating and cooling plant. From this survey and our experience, we can identify areas of improvement that will reduce their energy demand. We will then use dynamic energy modelling software to run simulations of said improvements to offer an overall prediction of the expected reductions.

Energy Audit - Portfolio:

What’s an energy audit for a portfolio?

A Portfolio energy audit is a virtual or digital energy audit of a large number of buildings, normally used by larger corporations looking to reduce their commercial CO2 emissions.

What’s the difference between this and a single building audit?

As useful as a single building energy audit is, the survey is time-consuming and if a portfolio of 100 buildings across multiple countries requires analysis then it becomes an unfeasible task. This is where portfolio energy auditing becomes useful, as a selection of strategic sites are surveyed and simulated in energy modelling software, and the results from these are benchmarked for all other sites. So it’s the advantage of having results for a large number of buildings, without the cost heavy implications of surveying many buildings providing the portfolio manager with a fast and cost-effective prioritization of a portfolio of buildings.

Why would I need one?

Again, to save money, a lot of money over a portfolio of buildings. As with a standard audit, you can save expenditure on the usual day-to-day utility bills and taxes through the reduction of the development’s carbon footprint. Spread across a portfolio of buildings this saving can be significant.

Stats, Facts & Savings



The energy used in creating and sending an average email has a carbon footprint of 0.3g CO2e.*



That’s the equivalent of walking through an external door of a heated building on a winters day.



If Britain’s overall workforce sent two less emails per day each year, it would save the carbon dioxide equivalent of 35,000 economy flights between UK and Spain.
