What ecoworks does

ecoworks GmbH is a Berlin-based general contractor specializing in serial renovation of multi-family residential buildings in Germany. Founded in 2019 by Emanuel Heisenberg, the company delivers turnkey climate-neutral modernizations to German housing companies, municipal providers, cooperative housing associations (Wohnungsgenossenschaften), and large private landlords. It currently runs over 20 concurrent renovation projects across Germany, concentrated on post-war building stock (1950s–1980s) typically rated energy class G–H. Named customers include TAG Immobilien, GWW Wiesbaden, Dawonia, GEWOBAU Erlangen, PATRIZIA, and the cooperative Wohnungsverein Hagen, which in March 2026 commissioned Germany's largest cooperative serial renovation — a €23 million project covering 12 buildings, 192 apartments, and approximately 15,000 sqm.

The company's core technology integrates digital planning, industrial prefabrication, and integrated building services. Planning begins with 3D laser scanning to create millimeter-precise digital twins, supplemented by AI-based image recognition on 3D satellite data for portfolio scoring and typology identification. A proprietary 300+ component catalog enables automated building-specific planning. Factory-prefabricated timber-frame façade modules integrate insulation, triple-glazed windows, external sun shading, decentralized ventilation with heat recovery, and a unique 'Backpacker-Strang' façade-mounted supply line routing that eliminates invasive in-apartment pipe work. Prefabricated roof modules are pre-fitted for photovoltaic integration, and air-to-water heat pumps enable NetZero operation. The system shifts approximately 80% of construction value from the site to the factory and reduces on-site construction time by 30–70%, achieving up to 83% energy demand reduction and KfW Efficiency House 55 or NetZero standards.

ecoworks operates as the sole Generalübernehmer (general contractor) from initial portfolio analysis and planning through production, installation, and handover. Pricing is project-specific fixed lump-sum contracts (Pauschalfestpreis) with binding timelines; customers can claim KfW 261 and BEG subsidies covering up to 45% of eligible costs. Revenue is one-time project fees per renovation contract, billed across multi-year engagements. Sales are enterprise field sales to housing-company boards and technical directors, supported by industry-event presence (Expo Real, Real Estate Arena, DENEFF, GdW WohnZukunftsTag), GdW Fördermitglied status, and a content marketing operation. The company has raised approximately €69 million cumulatively, including a €40 million Series A in December 2023, and won the German Sustainability Award in December 2025 as the first serial renovation provider to receive the honor.

Core offering

ecoworks operates as a general contractor (Generalübernehmer) for the climate-neutral serial renovation of German multi-family residential buildings. The integrated offering combines 3D laser-scanned digital twin planning, factory-prefabricated timber-frame façade and roof modules, and turnkey installation of low-temperature heat pumps, photovoltaic systems, and decentralized ventilation with heat recovery, delivered as a fixed-price lump-sum project contract. Approximately 80% of construction value is shifted from the building site to the factory, enabling renovation of occupied buildings to KfW Efficiency House 55 or NetZero standard in weeks rather than months.

Product overview

ecoworks is a Berlin-based proptech company and pioneer of serial renovation (Serielle Sanierung) in Germany. Its product portfolio is organized as an integrated serial renovation system — a turnkey general contractor offering that combines six core hardware sub-products (prefabricated façade elements, roof elements, energy supply/heat pump systems, basement ceiling insulation, living space expansion, and smart balcony systems) with a digital planning layer (3D laser scanning, AI-based satellite image analysis, a 300+ component catalog, and digital twin modeling) and an operational monitoring layer (continuous sensor-based energy monitoring and digital twin analytics). The system delivers buildings to KfW Efficiency House 55 or NetZero standards, shifting approximately 80% of construction value from the building site to the factory. Core products are complemented by content offerings including a Serial Renovation Whitepaper and a Public Procurement Guide developed with CBH Rechtsanwälte. ecoworks acts as system integrator and general contractor, working with a network of European timber construction partners (including Oikos Group, Bien Zenker, Hanse Haus, Living Haus, and Brüninghoff) for production capacity and scalability.

Scale indicators7 records

Recent moves5 records

Expansion highlights6 records

Broad incumbents

• Saint-Gobain: Global building materials leader offering façade systems, insulation (Isover), and increasingly integrated renovation solutions. Comparable as a potential serial renovation entrant with deeper capital and an existing European housing sector footprint that could challenge ecoworks' specialized niche.
• Daikin: Global HVAC leader with strong heat pump portfolio (the core energy system within ecoworks' NetZero offering). Daikin's scale and existing housing-sector relationships make it a logical broad competitor or partner for the thermal component of serial renovation projects.
• Kingspan Group: Leading manufacturer of high-performance insulation and building envelope panels with growing investment in deep retrofit solutions across Europe. Overlap with ecoworks' prefabricated façade and roof element approach makes Kingspan both a potential supplier and a credible competitive entrant at scale.
• Wienerberger: Austrian building materials giant (bricks, roof, façade systems) increasingly active in renovation and energy efficiency across DACH. Comparable as a broader building envelope provider that has signaled interest in integrated retrofit solutions and could compete with ecoworks' timber-frame approach.
• Viessmann (Carrier): German-headquartered heating systems specialist (now part of Carrier) offering heat pumps and integrated climate solutions for residential renovation. Highly comparable to ecoworks' energy supply module (heat pump + PV + ventilation) and is a dominant incumbent in the German heating replacement market.
• Goldbeck: One of Germany's largest construction companies, specializing in systematized/serial building design and construction with strong housing-sector presence. Closest large-scale incumbent to ecoworks' industrialized construction approach, though focused more on new build than renovation.

Direct peers

• Energiesprong: Originated the serial renovation concept in the Netherlands (2010) and the model ecoworks adapted for Germany. Energiesprong delivers net-zero energy retrofits of social housing using prefabricated façade/roof modules and integrated heat pump + PV systems on a similar general contractor basis, making it the closest conceptual peer.

Emerging players

• Renovai: Berlin-based renovation startup offering digital planning tools and a marketplace connecting homeowners with contractors. Adjacent emerging player focusing on software-enabled renovation rather than prefab delivery, but addresses the same housing renovation opportunity in Germany.
• 1Komma5°: German climate-tech scaleup offering integrated heat pump, solar, EV charging, and dynamic electricity tariffs through a 'heartbeat' OS to homeowners. Partially comparable as a complementary decarbonization player in German residential buildings, though focused on single-family homes and individual systems rather than multi-family serial renovation.

Others

• BuildingMinds: Berlin-based digital twin and building data platform for real estate portfolios, serving many of the same German housing companies as ecoworks. Comparable as a digital infrastructure layer adjacent to ecoworks' digital twin component and a potential partner or competitor in the building analytics layer.
