Best Practices for Renovating Residential Buildings: García Rama’s Expertise in Energy Retrofit Solutions
Upgrading ageing residential buildings to meet modern standards of comfort and energy efficiency is a challenge many communities face. Renovation is no longer just about aesthetic improvement. It is a critical process for enhancing energy efficiency, occupant comfort, and the long-term value of a property. García Rama, a construction company based in Asturias, Spain, has over 30 years of experience in residential building rehabilitation, specialising in façades and delivering comprehensive turnkey renovation solutions.
A central element of García Rama’s approach is improving the building envelope. Their approach considers the building as an integrated system rather than addressing isolated issues such as damp walls, structural cracks, or leaking roofs. The focus is on the thermal envelope, which is the barrier between a building’s conditioned interior and the outside environment. Interventions involve the installation of ventilated or technical façades with integrated insulation, which improve energy performance, reduce heating costs, and address common problems in older buildings such as condensation, moisture infiltration, and structural wear.
Typical interventions include façade insulation and cladding, window replacement, roof insulation, and the installation of photovoltaic panels. Technical façade systems can be finished in materials like ceramic, steel, or glass, creating a continuous insulating layer that enhances both appearance and thermal performance. Complementary measures, such as high-performance window units and upgraded roof insulation, prevent draughts and heat loss, while energy-saving installations like solar panels further reduce environmental impact.
Before any renovation begins, García Rama conducts a detailed assessment of the building. This includes structural testing of load-bearing walls and thorough inspections of façades, roofs, and other critical elements. The assessment identifies the most suitable façade solution for the building, considering various options and materials, and includes the preparation of a draft Energy Performance Certificate (EPC). The aim is to identify a cost-effective approach while achieving significant reductions in non-renewable primary energy consumption. The results inform a tailored renovation programme, specifying interventions, estimated costs, and required resources. Each project is customised to the building’s unique conditions as well as the homeowners’ preferences and financial circumstances. Reductions in energy use and CO₂ emissions are calculated via the EPC, and renovations are carried out with a guarantee that the energy performance targets will be met.
García Rama offers a turnkey renovation service: once the client approves the project, the company coordinates all aspects of the renovation, including grant applications, permits, financing, and the sourcing of technology providers, in exchange for a monthly fee from the homeowners. Once work begins, effective coordination between all departments during execution is essential. García Rama oversees operations across the technical office, on-site teams, and industrial facilities, ensuring that permits are processed and materials are ordered, manufactured, and delivered on schedule. The company’s capacity to bulk-purchase and produce façade components enables efficient supplymanagement, while workers are assigned tasks according to their skills and workload, ensuring smooth progress and adherence to timelines.
Sustainability is integrated throughout the renovation process. Materials are selected for durability, thermal performance, aesthetics, and low carbon footprint. Energy rehabilitation also extends the lifespan of residential buildings by 50 to 70 years, reduce energy consumption, eliminate moisture-related issues, and improve overall comfort, offering both economic and quality-of-life benefits for residents.
Recently, García Rama has expanded its business model to neighbourhood-scale renovations. By treating entire residential areas as a single project, the company achieves economies of scale and delivers integrated, efficient solutions.
Through a focus on energy efficiency, structural integrity, and habitability, García Rama demonstrates that residential renovation is more than construction. It is a way to improve comfort, save energy, and give buildings a new lease of life.
