Case studies

This sustainable Oostvoorne home blends into its forested setting with natural materials, energy-efficient systems, and biophilic design that harmonises architecture and environment.

A health sector building in Western Slovenia underwent energy renovation in 2019, achieving an SRI score of 18%, with potential upgrades like photovoltaic panels and smart systems promising a rise to 51% and improved efficiency, comfort, and flexibility.

A draughty cottage in Blackburn North was transformed into a sustainable, energy-efficient Passivehouse-standard home using recycled materials and ecological design.

The office building in Aix-en-Provence, built in the 1970s, has an SRI score of 39%. Suggested improvements, like upgrading the heating, lighting, and ventilation systems, adding solar panels, and installing motorised sun protections, could raise its score to 51%, enhancing energy efficiency, comfort, and flexibility.

This 2024 semi-detached Passive House in Évora, Portugal, features energy-efficient design, including solar panels, heat recovery ventilation, and a thermosiphonic system, with a focus on low heating demand and renewable energy generation.

The Elmen social housing project in Luxembourg showcases sustainable design with smart energy systems, achieving a 40% SRI score, with potential upgrades to boost efficiency, comfort, and storage.

An off-grid, timber-framed barn replacement in Norwich features sustainable design, cellulose insulation, rainwater harvesting, and a 12 kWp PV system with battery storage, achieving exceptionally low energy demand.

The rehabilitation of a 'Cabaña Pasiega', a detached single-family house in Cantabria (Spain), preserves its exterior stone while enhancing energy efficiency with insulation and sustainable systems to meet EnerPHit certification.

The NeoBuild office in Bettembourg, Luxembourg, is a sustainable pilot project with renewable energy features and an SRI score of 67%, which could be improved to 91% through smart grid integration, more EV charging stations, and predictive management.

The project is the design and construction of a 149.74 sq.m. off-grid passive house on Aegina Island, Greece, featuring energy-efficient systems, renewable energy generation, and a steel structure for fast construction, certified as Passive House Premium.
