Identifying, assessing and organizing the different energy saving opportunities based on their profitability, getting a reliable knowledge of current energy consumption. Entailing a energy saving and, as a consequence, economic one for the building premises.

The main aim is to reduce energy consumption when the object of study is an occupied building, keeping and improving at the same time hygrothermal comfort, sanitation and safety.

The objective is to achieve more efficient buildings through improvements in the building envelope, HVAC systems and lighting.

Energy Audit - Benefits

The cost saving and the improved environmental impact of our building.

The actions to be taken can be designed in phases, according to the possibilities of the system, grants and initial objectives.

In the case of residential buildings, the cost of an Energy Saving Study is minimal: About 30 euros per household for a block of 100 houses.

Some of the measures mean zero investment and immediate benefit, as the renegotiation of contracts with companies, obtaining a rapid recovery of the audit costs.

The rerecovery time of other measures can range from one year to seven years.


Energy Building Refurbishment

Energy Building Refurbishment - What is it?

After an Energy Audit the next step will be the Energy Building Refurbishment according to the recommendations of the audit. After reaping the rewards with the amortization of the investment.

There are approximately a 70% of buildings built ten years ago without taking into account the isolation measures considered basic today.

Energy Building Refurbishment - Benefits

The main profits are immediate economic savings and more comfortable buildings.

Energy Building Refurbishment - Costs

It is estimated that the cost of implementing these measures is depreciated over 10 years, giving real cases of seven years.

The amount of energy criteria can represent the 10% of a refurbishment work. It is about a reasonable cost, especially given the continous increase in the energy prices.


Maintenance Management Systems

Maintenance Management Systems - What is it?

Its purpose is the provision of appropriate expertise in order to get the best way of solving the problems started out in the maintenance and operation of facilities, as well as vigilance in compliance with them and their results.
