The problem

Your building is losing value every day

0
%

of buildings in Spain fail on energy efficiency

01

Do you know if your installations comply with RITE or PCI?

Technical audit spots critical issues before they become a fine or a shutdown.

02

How much do you lose every month to technical inefficiencies?

Oversized equipment, uncoordinated HVAC and phantom load — money walking out silently.

03

Who keeps your building's information when the contractor changes?

Without a Digital Building File, every handover costs you time, money and lost knowledge.

Independence We work for you, not for the manufacturer Cross-commissions with vendors

Frequently Asked Questions

We answer your questions

Energy Savings Certificates (CAE) are an official mechanism to monetize energy efficiency. They allow companies to receive direct economic compensation from energy retailers for every kWh saved.

You receive a direct cash payment that helps fund and amortise your efficient installations. It's money entering your bank account on top of monthly savings on your power and gas bill.

Any measure that reduces energy consumption: thermal insulation upgrades, LED lighting, renewal of HVAC systems, ventilation optimisation, etc.

Age is the key factor (over 15 years), but so are recurring breakdowns, difficulty finding spare parts and unusually high energy bills compared with the competition.

You risk critical activity shutdowns at the worst moment, runaway energy costs and potential financial penalties for non-compliance with the 2030 Energy Regulation.

All savings are validated by an independent Energy Savings Verifier accredited by ENAC, ensuring every kWh saved complies with current regulations.

Offices, retail premises, industrial warehouses, residential buildings, hotels, schools and any property with significant energy use.

Last year's average was between €123 and €144 per MWh of certified savings. We help you maximise the sale price by negotiating with the Obligated Parties.

A technical report with the real state of your building: MEP installations status, regulatory compliance (RITE, PCI), quantified energy savings opportunities and a prioritised action plan.

We work as Lead Engineer, not as contractor. That means a 360° view of the building, full independence from manufacturers, continuous technical oversight and monetization via CAEs and subsidies. The contractor reacts to breakdowns; we orchestrate and monetize the full cycle.

The Digital Building File always belongs to the owner. You keep the MEP inventory, the O&M history and all data accessible even if you change contractor or manager. No lock-in, no lost knowledge.
