A building design strategy based on passive strategies, low-carbon local materials, and climate-responsive construction to reduce energy demand and improve comfort. Natural ventilation, solar protection, and high thermal inertia help mitigate heat stress and adapt the building to changing climate conditions, while a simple, durable structural system enhances long-term performance. Together, these measures deliver a low-energy housing solution that is well integrated into its context and resilient to climate change.

Analysis and catalogue of EU-funded projects related to Modern Methods of Construction (MMC) using dry and off-site techniques for building energy renovation. The standardized catalogue of modular solutions—covering materials, systems, and integration methods— aims to shift from traditional on-site processes to off-site, thereby reducing costs and time while enhancing quality. Despite each project’s unique features, common challenges are identified, and a clear trend emerges toward multifunctional modular façades that are customizable in appearance and capable of integrating renewable energy systems like Building Integrated Photovoltaics (BIPV) and Mechanical Ventilation Systems (MVC).

New ways of organising, financing and delivering social housing renovation projects throughout a building’s entire life cycle, from design and construction to operation and eventual reuse. By bringing together public and private partners, these models aim to make large-scale renovations more affordable, scalable and sustainable, while supporting innovative renovation methods and procurement approaches that deliver long-term environmental and social benefits.

Multifunctional Heat Pump Systems provide heating, cooling and hot water through a single, highly efficient solution. The system combines heat pumps with innovative solar panels that generate both electricity and heat, reducing the need for fossil fuels. It can also recover waste heat from cooling and reuse it to preheat water, making better use of available energy. Particularly suited to residential buildings, this approach delivers greater comfort while lowering energy consumption and carbon emissions.

The IAQ platform is a combined Indoor Air Quality (IAQ) sensor and a user-friendly web interface. The IAQ sensor measures various quantities defining the indoor environment such as temperature, humidity, CO₂ concentration, VOC concentration, particulate matter (optional), and barometric pressure. The measured quantities are then used to inform the user, directly control technology in the building (AHU, HVAC), or provide necessary data to a superior system via Wi-Fi, LoRa WAN (optional), Modbus TCP (over Wi-Fi), RS485 with Modbus RTU.  The sensor is equipped with a RGB LED indicator or LCD display.

A new smart controller helps heat pump systems run more efficiently and reliably. It uses two advanced tools in a small, easy-to-use device. It consists of a model predictive control (MPC) algorithm that looks at weather forecasts, building use, and energy prices to run heating and cooling at the best times to reduce energy costs. A fault detection and diagnosis (FDD) algorithm also watches how well the system is working, spotting problems early and helping fix them before they get worse. Both tools are built into a simple platform—like a Raspberry Pi—making the system flexible and easy to test.

The aftercooling concept is an innovative district heating substation for large multi-apartment buildings where the domestic hot water preparation and reheating of the circulation flows are decoupled and obtained in two separate heat exchangers connected in parallel. The primary return temperature flow from the circulation heat exchanger is further aftercooled by the space heating system before returning to the district heating network. The concept provides a reduced return temperature to the district heating network.
