Solar PV scale smart battery systems are an integrated energy solution that combines rooftop solar photovoltaic (PV) panels with on-site battery storage in large residential buildings. The system is designed to demonstrate and monitor how locally produced solar energy can be stored and optimally used at building and neighbourhood scale, increasing self-consumption, reducing grid dependency, and improving overall energy resilience.

A smart way to understand how much solar energy can be generated across an entire neighbourhood. Using digital 3D models and energy simulations, it identifies the rooftops and façades best suited for solar panels and helps communities plan renewable energy investments more effectively. Beyond the technical potential, the approach also considers costs, opportunities for local energy sharing and the benefits of involving residents in energy communities. Designed to be adaptable to different cities and contexts, it supports the development of cleaner, more resilient and locally produced energy systems.

The school courtyard was redesigned as a park with varied vegetation heights and a combination of permeable and natural surfaces, covering at least 30% of the outdoor area. The design supports local surface water management by retaining and infiltrating rainwater on site, in line with the City of Oslo’s approach to reducing runoff impacts on buildings, infrastructure, and surrounding areas.

The solution combines solar energy generation, battery storage and electric vehicle charging into a single, intelligent building energy system. Solar panels integrated into building façades and rooftops produce clean electricity while also improving indoor comfort by reducing overheating. Energy can be stored in repurposed batteries, giving a second life to existing technologies and helping balance supply and demand. The system also supports smart charging of electric vehicles, allowing cars to store or even supply electricity back to buildings when needed. By optimising energy use in real time, this approach makes neighbourhoods more energy-efficient, flexible and resilient.

Coloured PV panels installed on the roof and façade of a building to maximise renewable energy production and provide surplus energy. The design of the PV modules layouts is defined by the PV modules orientation in relation to the sky, the orientation of building longest facades, and the regulatory provision regarding the appearance of the PV façade.

Use of eco-friendly local construction materials and traditional craftsmanship in sustainable renovation projects. By combining natural and low-impact materials, such as timber and local sandstone, with modern construction techniques, it aims to reduce the environmental footprint of buildings while supporting local producers and preserving traditional building knowledge. An online catalogue of sustainable construction solutions further helps designers and builders compare materials based on their environmental performance and encourages the wider adoption of locally sourced, circular building practices.

A two-step methodology that aims to select the cost-optimal solutions for retrofitting of buildings in large-scale renovation process (200-300 dwellings). From a set of different potential combinations of passive elements (e.g., adding different insulation materials with different thickness and/or windows) and active elements (e.g., heat pumps / multi-split air conditioning for heating, cooling and DHW and/or photovoltaics), the methodology helps to select the most appropriate combination considering the energy performance and economic parameters. The process aims to select solutions that achieve a 50% reduction in the energy demand and/or a significant improvement in the thermal comfort conditions. A detailed economic model is part of the methodology giving as a result the following outputs: investment costs deducting grants for each owner and life cycle global costs.

A catalogue of integrated circular and low-carbon solutions for building design and renovation. It provides policymakers, architects, urban planners, and technical practitioners with practical references applicable across all stages of the building lifecycle. Each solution is presented with a concise description, the challenges addressed, targeted objectives, expected performance, and associated benefits. The catalogue also includes examples of best practices for implementation.
