Energy Audit

An energy audit answers three questions: how much the facility really consumes, where it loses that energy, and which actions will pay back fastest. It is based on actual data — invoices, meter readings, automation logs — rather than calculated values.

This is what distinguishes an audit from an energy performance certificate. A certificate is created in a normalized model and describes how a building should behave under assumed operating conditions. An audit describes how it actually behaves — with all the differences resulting from settings, operating schedules, system condition, and the way tenants use the building.

The result is not a description of the current state, but a list of actions ranked by the relationship between cost and effect. In practice, it is divided into two parts. The first covers adjustments in the way the building is operated — settings, schedules, controls — that cost little or nothing. The second covers investments in the building fabric and systems, requiring a budget and a timeline. The order matters: in most buildings, the first group delivers part of the savings before any investment decision is made.

The scope includes:

1. analysis of the consumption of all energy carriers
2. assessment of the external envelope and the condition of installations
3. review of HVAC, lighting, domestic hot water and automation
4. verification of metering and the quality of measurement data
5. analysis of the potential for implementing renewable energy sources
6. a list of actions with cost estimate, savings and payback period
7. implementation plan and verification of achieved results

Expert Opinion

“Most buildings do not need investment first. They need to know where they are losing energy — because some of those losses cost only a change in control algorithms”

Benefits

Lower operating costs

Savings visible in utility bills and, in commercial buildings, also in the operating charge billed to tenants.

Results without capital expenditure

Some losses result from settings and schedules, not from the technical condition of the building. These measures can be implemented immediately.

Investment sequence based on numbers

Each action comes with a cost estimate, projected savings and payback period. The budget goes where it works hardest.

Starting point for decarbonization

A reliable energy balance is a prerequisite for a credible CRREM assessment and a sensible decarbonization pathway.

Improved energy performance

The implemented measures translate into the building’s energy class, and that into its position with tenants and financiers.

Data for financing and reporting

The same material supports applications for green financing, taxonomy documentation and reporting obligations.

Audit objective- We determine what the result is meant to be used for — cost reduction, financing, certification, or reporting. Result: the scope and depth of the analysis tailored to the intended use.
Data and documentation- We collect invoices, readings, technical documentation, and records from automation systems. Result: a picture of consumption over time instead of a single snapshot.
On-site inspection - We verify the condition of the installations and partitions on the facility, carrying out supplementary measurements if needed. Result: confirmation that the documentation matches reality.
Energy balance - We break down consumption by individual systems and identify the sources of losses. Result: knowledge of exactly where energy is being lost and on what scale.
Action catalogue - We estimate the cost of each measure and rank them by return, distinguishing between no-investment and investment measures. Result: a plan that can be turned into a budget.
Implementation and verification - We support implementation and verify the achieved results using measurement data. Result: confirmed savings instead of a forecast in the report.
