Our Process
How we conduct an energy audit
Our methodology is systematic, non-invasive, and designed to produce a report that is immediately usable by your building committee. Here is what happens at each stage.
Our methodology is systematic, non-invasive, and designed to produce a report that is immediately usable by your building committee. Here is what happens at each stage.
Each stage of our process is designed to build on the previous one, ensuring accuracy and completeness in the final report.
Before any site visit, we hold a preliminary conversation with the building administrator or committee representative to understand the building's characteristics, current concerns about electricity costs, and the scope of systems to be audited. This allows us to plan the on-site visit efficiently and prepare the right measurement equipment.
We review any available documentation such as recent electricity bills, equipment inventories, and building plans to establish a baseline understanding before arriving on site.
Our technical team visits the building and measures the actual power consumption of every common-area electrical system using calibrated instruments including clamp meters, power quality analysers, and lux meters. We measure under real operating conditions — not theoretical specifications from equipment nameplates.
We document operating schedules, control logic, equipment age, and physical condition. For systems with variable consumption such as elevators and pumps, we take measurements across multiple operating cycles to obtain representative averages.
With field measurements complete, we calculate the annual energy consumption and cost of each system using current Chilean electricity tariff data applicable to the building. We identify which systems represent the largest opportunities for reduction.
For each system where improvement is technically and financially viable, we model replacement scenarios using available efficient technologies. We calculate projected annual savings in both kilowatt-hours and Chilean pesos, and estimate the payback period for each recommended investment.
We prepare a structured written diagnostic report that presents findings clearly and in a format suitable for presentation at a residents' assembly. The report is not a technical document full of jargon — it is designed to be understood by committee members and residents without an engineering background.
The report includes an executive summary, detailed findings by system, prioritised recommendations, savings projections, and payback periods. We are available to discuss the findings with the committee and answer questions.
Understanding the boundaries of our service is as important as understanding what we offer. Vexloni is a diagnostic consultancy. We measure and analyse — we do not sell replacement equipment and we do not perform electrical installations.
This means our recommendations are based solely on what the data shows. When we suggest a specific type of technology upgrade, it is because the measurements support it — not because we have a commercial relationship with a supplier.
