ECS bridges the gap between historic building restoration and modern, ultra-efficient NZEB standards. As a premier nationwide consultancy, ECS provides the expert guidance, material supply, and rigorous installation supervision required to create a healthy, energy-independent property anywhere in Spain.

Their whole-house approach begins with a breathable “eco-envelope” using natural materials like Diasen solid wall renders, Steico wood fibre, carbon-negative hemp, and clay plasters. ECS then seamlessly integrates advanced climate control—including carbon matt heating, high-efficiency heat pumps, and smart ventilation—all powered by custom solar and battery systems. Whether a client is restoring a traditional Spanish ruin or building a state-of-the-art new home complete with luxury spa hardware, ECS ensures the project is flawlessly executed to remain damp-free, highly efficient, and fully self-sufficient.
