Energy audits are conducted to optimize the energy consumption and costs related to the building’s operation. It is a complex process performed in three main stages:
- Data collection — the first stage consists of documentation review, inspection of the facility and measurements and inventorying the devices making up the HVAC systems and electrical systems. Moreover, data from energy invoices and data related to technical maintenance of the facility are collected.
- Data analysis — as part of the second stage, an analysis of data collected during stage one is performed. This forms the basis for preparation of a numerical model of the building which illustrates the energy consumption areas.
- Findings and recommendations — the last stage consists in presentations of improvements aiming at energy consumption savings and optimization.
Audits are conducted for individual facilities and for networked projects.
