Renewable energies and energy efficiency

Sizing and profitability studies, drafting of technical specifications, project preparation, site management, turnkey projects, commissioning in detail ( commissionings )

In Colomer-Rifà we introduce renewable energies in all our projects.  We aim to select the system that best suits the needs of each client, in terms of budget, return on investment, energy savings, energy production, timmings, etc. We specialize in solar thermal, photovoltaic, biomass, geothermal, aerothermal, etc.

Energy efficiency is a priority for Colomer-Rifà. Our projects incorporate improvements in terms of energy efficiency from the first phase of design, through the selection of materials, to the last phase of construction. Our goal is to minimize the amount of energy required in all of our buildings. A very important form of passive energy saving.
