Comprehensive Energy Audit Service

Comprehensive Energy Audit

The Comprehensive Energy Audit Service is the most effective way to determine the full scope of issues affecting the energy performance and efficiency of your home. This audit is a thorough examination of your entire home, focusing on all potential sources of energy loss. The Comprehensive Energy Audit examines doors, windows, walls, roof, insulation, heating and cooling equipment, and so on. The Blower Door and Duct tests are included in this evaluation. To assist in determining problem areas, a thermographic camera will be used as needed. A comprehensive report is provided, detailing our findings and making recommendations for improvement.

A building energy audit is a systematic procedure that aims to evaluate the building’s current energy consumption, identify potential energy savings, and report the findings. In the building sector, it is an important tool for energy conservation and for implementing energy efficiency measures as well as extending the life of electromechanical equipment. The importance of a well-structured and organized energy audit methodology as the most important tool for the energy certificate of buildings is highlighted in this paper, as part of the implementation of the Energy Performance of Buildings Directive (EPBD).

The importance of a well-organized questionnaire for the energy profile of the building is discussed, as well as the context of such a questionnaire and the row data that must be collected. The significance of undisturbed measurements such as thermal and optical comfort measurements, electrical consumption measurements, gas emissions readings, and IR thermography is highlighted. Furthermore, some specific examples are provided to highlight the importance of in situ measurements, with a focus on the thermographic method.

Requirements Of Comprehensive Energy Audit:


The energy audit along with Electrical Safety Audit consists primarily of gathering and measuring data that is useful for the building’s energy assessment. Its primary goal is to conduct an initial energy survey and identify operation and maintenance procedures. Its primary goal is to describe and assess current energy demand and consumption, identify potential and critical energy management improvements, and, ideally, offer an energy management plan.

The data collected during the energy audit, both from observing/measuring the building, collecting data, and interviewing tenants, must describe the energy demand of the building, which is primarily affected by building use and the building envelope, as well as the energy consumption, which is primarily affected by the equipment and type of energy used for heating, cooling, ventilating, lighting the building, and heating sanitary hot water.

Thus, a well-structured questionnaire should include at least the following information:


  • Creating a location/relationship with its surroundings and orientation;
  • Area and volume of the building;
  • The materials used to construct the walls, roof, and floor, as well as the type of windows and openings and their proportions on each façade, as well as the type of shading;
  • Mode of operation and occupancy;
  • The type of boiler used to heat the space and/or sanitary hot water, as well as the fuel used and the mode of operation;
  • The type of air conditioner and its mode of operation;
  • The type and number of light bulbs, as well as their operation mode;
  • The amount of electricity consumed by other appliances and the mode in which they operate;
  • Energy-saving and energy-management systems in the building, if any;
  • At least three recent years’ worth of energy consumption bills (for oil, gas, and electricity);
  • Building blueprints are available;
  • Building users’ satisfaction with thermal and visual comfort in the current situation.

Aside from a visual inspection of the building and its systems, it is critical to conduct measurements of the following during the energy inspection:

  • Building envelope and distribution system characteristics using heat flux and surface temperature sensors, endoscopes, or infrared thermography, the latter providing a more complete picture of the component’s thermal performance;
  • Thermal and visual comfort, using air and globe temperature sensors, relative humidity sensors, air velocity sensors, and lux meters;
  • Electrical consumption, as measured by energy analyzers.
  • The efficiency of boiler systems as measured by flue gas analyzers.

All of this information is required to create the building’s energy consumption profile. The energy consumption of similar buildings can differ significantly depending on the typical building characteristics (building envelope, use, and equipment), but also on the occupants’ behaviour, for a variety of reasons that cannot be detected by theoretical calculations, past bills, or in situ measurements. The measurements show that a significant portion of the consumption is due to “stand-by” mode and equipment that operates 24 hours a day, including weekends. This leads to the possibility of energy savings management, focusing on the reduction of standby load, among other measures, information that could not have been obtained from . “asset” rating or collected monthly electrical bills.

Benefits of conducting Comprehensive Energy Audit Service:


Continuous monitoring of a facility’s energy consumption, or energy-consuming equipment, entails the collection and analysis of energy data from building systems and can provide customers with real-time energy information.

This data assists facility managers in managing resource consumption and maintaining optimal equipment performance.

The following are the primary advantages of energy monitoring:

  • Energy Analytics quantifies and evaluates previously undiscovered data on building systems and operating parameters
  • The use of interactive dashboards for facility employees and/or for public displays, such as in-office monitors, can increase energy awareness for facility occupants and has been shown to positively influence people’s behaviour, resulting in lower utility costs.
  • Automated Notifications monitor energy consumption and system operations in real-time, allowing for the detection of errors or faults within a system. Customized alarms can be configured to prevent inconsistency or overconsumption.
