The Shift to Consulting
ECS is a dedicated energy and natural insulation consultancy. Ten years ago, we started out spraying natural cork insulation down in Cádiz. To be frank, spraying is physically punishing work, and between the aching joints and needing reading glasses just to find the end of the spray nozzle, we simply got too old to keep doing it full-time. We handed that side of the business over to our trusted partners at BioReforma S.L., who now manage the contracting in Andalucía.

Today, operating from our base in Western Asturias, we focus entirely on what we do best: designing and building high-end, off-grid capable energy systems for residential and industrial use, and engineering breathable NZEB (Near Zero Energy Building) thermal envelopes using wood fibre, hemp, and cork renders. This is how you hit top-tier energy ratings without making the fatal mistake of trapping moisture in historic Spanish masonry with synthetic foams.
The Living Laboratory
None of our advice comes from a sales brochure. It is backed by trial, error, and real-world testing at our near-zero-energy (NZEB) showhouse in Asturias, which we use as a permanent living laboratory.
On-Site Integration
We haven't completely retired from the dirt. While our regional partners handle the heavy lifting, we still get outside and play with our heavy machinery in the nice weather to maintain our skills. And on your projects, we don't just drop off materials and disappear. When requested, we work directly alongside your builders to provide hands-on technical support, troubleshooting, and on-site training so the systems go in right the first time.
