Energy Audit

The energy audit is an essential tool for evaluating the overall efficiency of a building and related technological systems. This methodical process includes measurements, and in-depth analysis of energy flows, with the ultimate goal of optimizing consumption while keeping system performance unchanged.

Energy Conservation Opportunities (ECO) are identified through the energy audit, i.e. energy savings opportunities that can result in improving the efficiency of existing plants or, if necessary, in their partial or total replacement.
Energy optimization takes place in different phases, each fundamental for the identification and implementation of the best solutions.

Energy Benchmarking

The initial approach involves the normalization of consumption data for immediate comparison with reference values (deriving from sector statistics or case studies). However, for a more precise and personalized assessment of plant performance, advanced simulation models are used.

This method, exceeding the limit of a comparison based only on consumption data, allows a more accurate prediction of performance, taking into account crucial variables such as the size of the building and the climatic conditions.

Initial Energy Audit

The energy audit of a building requires an in-depth analysis that goes beyond simple monthly consumption data. For a complete understanding of energy behavior, it is essential to analyze overall bills and consumption. This phase allows you to calibrate the simulation models to obtain a precise evaluation. In addition, the audit includes evaluating the building's thermal performance and simulating its behavior to identify and correct any inefficiencies.

Detailed Energy Audit

This phase involves the collection of on-site measurements and monitoring data, essential for refining the calibration of simulation models. Particular attention is paid to identifying energy systems and their short and long-term consumption dynamics (daily, weekly, monthly or annual). Once the model is carefully calibrated, it is possible to precisely quantify the potential savings resulting from the proposed energy efficiency measures.

Investment-Grade phase

In this phase, the use of the data obtained from the calibrated models is essential for the analysis and identification of the most appropriate energy saving measures, thus directing the study towards a detailed engineering design.

The main activities to be carried out include:

Analysis of building characteristics and utility data: walls, floors, ceilings, systems and energy bills.
Study of real operating conditions: how the building interacts with climate and occupancy.
Evaluation of energy savings opportunities: identifying the most effective solutions.
Evaluation of potential energy savings: to optimize consumption and reduce energy costs.
Analysis of customer needs: customizing the approach based on specific objectives.

Infrared Thermography for Energy Audit

Infrared thermography is a cutting-edge technique for identifying potential critical issues in the building envelope. Through the production of thermal images of surfaces, this tool is essential in energy audits. In fact, it allows monitoring the heat transfer mechanisms - conduction, radiation and convection - offering a detailed overview of the areas that require specific interventions to increase energy efficiency.
