The demo site consists of 24 single-family houses with PV-equipped carports for energy production. Each house will have photovoltaic installations and salt-water battery energy storage. Energy production will be managed in a virtual community, allowing shared consumption and EV charging. Heat pumps and greywater heat recovery will cover heating, cooling, and water needs. Circular economy principles will guide construction using monoblocks and dismountable designs. Low VOC materials will be used for indoor air quality, and sensors will monitor energy, water, and indoor pollution levels. Greywater recovery will supply toilets. Administrative authorizations are secured, with infrastructure starting in late 2022 and completion by the end of 2024. The project aligns with Luxembourg’s sustainable building certification, LENOZ.
Site objectives
- Provide feedback on the technologies implementation (passive and active)
- Enable quantitative impact measurement (by deploying a Post-Occupancy Evaluation approach based on additional performance measurements (sensors) and running interviews and questionnaires with occupants), thus contributing to improve POSIFIT design process.
