Sustainable
Restoration &
NZEB Consulting
Bridging Spain's heritage buildings with Net Zero standards — natural materials, advanced climate systems, zero bullshit.
Built on a
life in the
trade
30 years in restoration. 20 years of lime and clay. A decade of focused NZEB consulting in Spain.
Built on a 30-year background in restoration and 20 years of hands-on lime and clay plastering, ECS began a decade ago as a focused project treating damp and spraying cork in southern Spain.
Today, our small team channels a lifetime of trade experience into our role as restoration consultants and nationwide distributors, bridging the gap between historic building restoration and modern NZEB standards.
Our whole-house approach begins with a breathable "eco-envelope" — Diasen solid wall renders, Steico wood fibre, carbon-negative hemp, and clay or lime plasters — then integrates heating, ventilation, and solar systems seamlessly.
Straight talking, stress-free projects, and absolutely zero bullshit.— The ECS Philosophy
A complete
whole-house
approach
From initial survey to post-project support — every discipline under one roof.
Heritage preservation meets Net Zero — from survey to full CTE compliance.
Steico, von Hanf, Rockwool, and Diasen — vapour-permeable and independently sourced.
Grid-tied and off-grid solar with battery storage for Spanish properties.
Carbon mat heating, hydronic radiant floors, and smart ventilation with heat recovery.
KRONOTERM aerothermic heat pumps — cut hot water costs by up to 75%.
Full project delivery via trusted partners including Bioreforma SL in Andalusia.
Bespoke energy-efficient installations using HUUM heaters and Steico wood fibre.
Pre-purchase assessment of insulation, damp, electrical, and energy systems.
Cellar excavation and land rehabilitation for restricted-access sites.
Bespoke lime, clay, and tadelakt wall finishes — textured, pigmented, and polished surfaces for interior and exterior.
Rigorously
tested.
Carefully
selected.
We constantly test and filter products — looking for the highest-performing materials. Every brand has earned its place.
Diathonite and Diasen — breathable, insulating, damp-resistant finishes.
E-NERGY CARBON mats, IDEAL hydronic radiant, and AIRUNIT ventilation.
Ultra-efficient aerothermic heat pumps — the gold standard for hot water in Spain.
Smart sauna heaters inspired by nature, for residential and commercial installs.
Clay plasters that regulate humidity and improve indoor air quality naturally.
Hands-on training for installers and architects in natural building and NZEB systems.
Seamless
from survey
to finish
Flawlessly executed, damp-free, highly efficient, and fully self-sufficient — whatever the building.
A thorough site visit covering structure, damp, insulation, and energy performance. Clear, plain-English report — no padding.
A whole-building strategy: eco-envelope, heating, ventilation, solar, and water — NZEB compliant and natural-material led.
High-performance natural materials distributed nationwide from our Barcelona and Asturias hubs, directly to site.
Through trusted partners including Bioreforma SL in Andalusia — we oversee execution until every specification is met.
We remain available after completion. From optimisation to remedial work — we stand behind everything we specify and supply.
