Energy-Efficient Renovations in Barcelona
Your home consumes more energy than it needs
Barcelona's building stock has an average age of over 40 years. Most homes lose energy through the building envelope—facades, roofs, and windows—and rely on obsolete climate control systems.
At Reformayahorra (CM-VINCO SL), a company founded by Tomas Moreno Llorca in 1995, we have spent over 30 years transforming homes in Barcelona with a focus on energy efficiency, sustainability, and real comfort. We combine design, technical engineering, energy performance certification, and grant advisory services so your renovation starts saving from day one.
Four Key Areas with Measurable Impact
Each area reduces energy consumption, enhances comfort, and increases property value.
Interior Thermal Insulation (SATI)
Insulation applied to the interior of walls, roofs, and floors. An ideal solution when exterior intervention is not feasible (protected heritage buildings, communities without facade consensus, or tight deadlines). Reduces heating demand and eliminates thermal bridges.
Aerothermia and Climate Control
High-efficiency aerothermal heat pumps (SCOP > 2.5) for heating, cooling, and domestic hot water. Eligible for subsidies up to €3,000 from ICAEN.
High-Efficiency Windows
Frames featuring thermal break technology and low-emissivity double glazing with argon gas. Reduces energy losses by up to 45%.
Biomass & Heat Recovery Ventilation
High-efficiency biomass boilers and systems paired with dual-flow mechanical ventilation (MVHR) that refreshes air without heat loss. Standard standard solution in Passivhaus renovations.
Data based on completed projects and active 2026 funding calls from Consorci de l'Habitatge de Barcelona, ICAEN, and IDAE.
