This site provides actionable guides on achieving energy and water independence, using natural insulation to kill heat loss and drive down costs. Our goal is to help you create a comfortable, low-maintenance, cost-effective home.
ECS is an energy and natural insulation consultancy. Our advice comes from real-world experience, not sales pitches, and we only recommend and distribute systems we personally use.
To keep our skills sharp, we take on select restoration projects alongside developing our living showhouse and workshop in Western Asturias. Although the build is less than 50% complete, it already operates as a near-zero-energy building (NZEB) with zero utility bills—proving the building physics work long before the project is finished.
As of 2025, BioReforma S.L. manages our former southern restorations and natural spray applications business, allowing ECS to focus entirely on technical consulting and distribution.
