What Inside Out does
Inside Out Technologies B.V. is a Utrecht, Netherlands–based company that develops prefabricated Plug & Play modular energy systems for the sustainable renovation of high-rise residential buildings, stacked housing, utility buildings, and offices. Founded in 2022 by Paul Das (CEO) and Joris van den Heiligenberg (CTO), the company builds six product modules — io Alpha (solar), io Bravo (climate), io Charlie (facade), io Delta (facade element), io Echo (balcony), and io Foxtrot (data/control) — that relocate building installations to the facade or roof, freeing interior space and minimizing resident disruption during renovation. The modules integrate building engineering (bouwkunde) and installation technology (installatietechniek) via a BIM-coordinated RGS (Result-oriented Collaboration) methodology running across six fixed phases from initiation through monitoring.
The company operates a hybrid B2B model: it sells hardware modules and delivers BIM-integrated engineering services directly to housing corporations, property owners, and commercial real estate clients, while distributing the Warmeflat commercial concept through an installation partner network that executes projects on-site. Pricing is quote-based with multi-year contracts, supplemented by recurring performance-monitoring services via the io Foxtrot data module. Customer wins include social housing corporations BoEx, Woonwaard, and Parteon (Henriëttedreef, Noordertogtflat, Albert Meijnsstraat), PwC's 30,000 m² Westgate II headquarters in Amsterdam, De Wilde Metaal, Universiteit Utrecht (Lumifield), and De Werf Almere. Operations are currently Netherlands-focused, with an HQ and production facility in Utrecht's Nieuw Overvecht business park and a headcount of approximately 67 employees.
In 2023, Inside Out secured a €4 million European Green Deal subsidy as part of the ARV-project consortium (covering Oslo, Palma de Mallorca, Sonderborg, Karviná, and Trento) to scale its renovation system for 1960s–70s housing stock, with the European Commission designating the system as most promising for scaling. The company's Henriëttedreef pilot (2018–2021) was the first renovated energy-generating flat in Europe, achieving 10% net-positive annual energy generation. Revenue is not publicly disclosed.

Inside Out product offering
Product offeringCore offering
Inside Out designs, manufactures and sells prefabricated Plug & Play energy modules (io Alpha solar, io Bravo climate, io Charlie facade, io Delta facade element, io Echo balcony and io Foxtrot data) that combine building engineering and installation technology into factory-built units installed on building facades or roofs. The modules are sold primarily to housing corporations, property managers and installation partners for rapid, predictable sustainable renovation of high-rise residential, utility and office buildings, supported by BIM-integrated engineering services and long-term performance monitoring.
Product overview
Inside Out offers a modular Plug & Play energy system architecture consisting of six interconnected modules designed for sustainable building renovation: io Alpha (solar module), io Bravo (climate module), io Charlie (facade module), io Delta (facade element), io Echo (balcony module), and io Foxtrot (data module). These prefabricated modules integrate building and installation technology, moving installations to the building facade or roof to maximize indoor space and minimize disruption. The modules work together as an integrated energy system managed by io Foxtrot, with optional configuration for customized projects. Products are offered under the Warmeflat commercial concept for housing corporations and VvEs in the Netherlands.

Products and services
- io Alpha - Solar Module Steel construction with fully prefabricated solar panel frames for building rooftops, allowing many more solar panels than the flat roof alone accommodates; built over existing obstacles such as boiler houses, heat pumps and chimneys; stormproof design; can be extended with electrical or thermal battery storage. Used for sustainable renovation of high-rise residential, utility and office buildings.
- io Bravo - Climate Module Complete Plug & Play climate hub combining heat pump, hot water generation, energy storage and intelligent control and monitoring in one compact module. Heating capacity 25–250 kW with supplementary peak heating, 2000L thermal buffer, passive cooling possible with convectors, and weather-forecast-based heating curve control. Delivers up to 70% energy savings and up to 40% energy cost savings.
- io Charlie - Facade Module Facade installation module containing a radiator, decentralized ventilation system and integrated solar panel; can be placed in window frame or facade within one day; features CO2-controlled ventilation and is suitable for low-temperature heating and cooling.
- io Delta - Facade Element Smart facade that can insulate, heat, ventilate and generate energy, replacing the existing building facade with a new shell containing installation technology; plug-and-play with pre-installed piping, heating and ventilation units; modular design enabling customization and renovation while residents remain in the building.
- io Echo - Balcony Module Balcony module that solves cold bridge problems while generating renewable energy from integrated solar panels in the balustrade; provides thermal insulation of existing balcony and generates solar power from south-facing balustrades.
- io Foxtrot - Data Module Data module acting as the brain of the energy system, collecting data from all energy flows in the building and autonomously controlling climate and energy systems; connects to weather forecasts, EPEX Spot energy market data and grid congestion data; enables self-learning energy management and controls collective heat pumps, solar power, batteries and charging stations; data stored on European servers.
- Warmeflat Commercial Concept Commercial concept for serial renovation of apartment buildings, deploying Inside Out's Plug & Play modules (primarily io Bravo) through installation partners; first concept rolled out by Inside Out for housing corporations and VvEs.

Inside Out competitors and assessment
Company assessmentBroad incumbents
- Schneider Electric: Global building energy management and automation company whose EcoStruxure platform competes with Inside Out's io Foxtrot for building-level energy optimization. Far larger scope and customer base, but does not offer prefab renovation modules.
- ABB: Global electrification and building automation company active in commercial and industrial energy management. Adjacent to Inside Out's Foxtrot data and control layer but without prefab building renovation hardware.
- ENGIE: Global energy services and building solutions provider active across European building energy renovation. Overlaps with Inside Out on integrated energy retrofits for residential and commercial buildings, but at vastly larger scale and with traditional service delivery.
- BAM Group: Major Dutch construction group operating across building, infrastructure, and property. Competes for the same Dutch renovation tenders and has sustainability initiatives, but lacks Inside Out's prefab Plug & Play module architecture.
- Heijmans: Large Dutch construction and infrastructure company with a sustainability-focused division targeting Dutch building renovation. Overlaps with Inside Out on housing corporation renovation projects but as a generalist contractor rather than a prefab energy specialist.
- Skanska: Large Nordic construction and project development company with established sustainability and green building initiatives. Comparable as a broad construction/sustainability incumbent across Northern European renovation markets, but lacks prefab energy module specialization.
- Dura Vermeer: Dutch construction company with growing focus on sustainable renovation and modular building methods. Direct competitor for Dutch housing corporation projects but without Inside Out's integrated six-module energy platform.
- Kingspan Group: Global leader in high-performance insulation and building envelope solutions, including integrated solar and energy systems. Comparable in the prefab building systems category but at much larger scale and broader product portfolio.
- NIBE Energy Systems: Swedish manufacturer of heat pumps and HVAC solutions for residential and commercial buildings. Comparable to the heat-pump component of Inside Out's io Bravo climate module, but a product specialist rather than integrated renovation system provider.
Direct peers
- SunRoof: Swedish company producing building-integrated solar roofs and facades. Most direct product overlap with Inside Out's io Alpha solar module and io Charlie/Delta facade modules, though narrower in scope (no heat pump or climate components).
