Energy efficiency
Energy Efficiency is essential to reduce energy consumption and reduce greenhouse gas emissions.
INTEMAC offers services designed to improve energy efficiency in buildings and industrial processes, through the implementation of advanced technologies and sustainable practices. Detailed assessment of energy needs allows for the development of customized strategies that result in significant savings and improved energy performance.

Energy audits
Intemac develops energy audits of buildings with the main objective of analyzing and diagnosing the energy flow of a given property, so that its consumption is determined in a particularized way and, from which, identify the parameters with the greatest incidence and, consequently, establish options to reduce it, with the consequent economic and energy savings.

Energy rating of buildings.
Intemac has developed energy rating actions for non-residential buildings (schools, hospitals, office buildings, etc.).
In these ratings, the building has been evaluated, regardless of its actual use, simulating homogeneous operating conditions for all cases, thus allowing buildings to be identified and compared by their energy quality and not by the use of their occupants, an essential consideration in the decision to buy, rent or refurbish a building.

Energy efficiency certificates.
Intemac has developed energy certification actions to obtain the label for non-residential buildings (schools, hospitals, office buildings, etc.). In these certifications, the building has been evaluated, regardless of its actual use, simulating homogeneous operating conditions for all cases, thus allowing buildings to be identified and compared by their energy quality and not by the use of their occupants, an essential consideration in the decision to buy, rent or refurbish a building.

Permeability of buildings (Blower Door Test).
Intemac has the material means to carry out this test that evaluates the level of permeability of buildings. To this end, a fan is placed at the main door of the building, which depressurizes (can also pressurize) the interior of the building and analyzes its airtightness.
From the measurements taken in the test, the air flow and pressure graph is drawn up, and it is calculated in number of renewals per hour (data for CE3X) due to uncontrolled infiltrations.
It is a test that does not cause discomfort, since it does not require works, and is carried out in a short space of time. It can be complemented with other measurements that Intemac also performs:
– Anemometers to locate infiltrations.
– Thermography to locate cold air flows where infiltrations are located.
Thermography.
Intemac has thermographic cameras and qualified inspectors to carry out thermographic studies on building envelopes, which allows
- Greater knowledge of the thermal state of the installation carried out
- Knowledge of existing losses (leaks) and therefore of possible points of action.
- Savings due to greater energy efficiency of the systems evaluated.
By studying the envelope in buildings we will be able to know and/or estimate functional problems of the building such as:
- Detection of water infiltrations: The areas where water infiltrates the façade usually have a different temperature due to the presence of moisture. Thermal imaging can reveal these differences and help locate specific spots where the leak may be occurring.
- Thermal insulation assessment: If there are deficiencies in the thermal insulation of a façade, areas where there is excessive heat loss or gain can be detected using thermography.
- Identifying thermal bridges: Thermal bridges are areas where heat transfer is highest due to a disruption in insulation, such as joints between structural elements. These points can be located with thermal imaging.
- Façade damage assessment: Thermal imaging can help identify damage to the exterior cladding, such as cracks or detachments, which can affect structural integrity.
- Monitoring environmental conditions: Facade thermography can also be used to monitor environmental conditions, such as the performance of solar panels installed on the façade or to detect hot areas due to excessive solar radiation.
This allows us to know the state of the buildings and warn of their potential for improvement.
