LEGOFIT Project

Adaptable technological solutions based on early design actions for the construction and renovation of Energy Positive Homes.

The LEGOFIT project will test and validate a process for making residential multifamily homes energy positive. The process itself is revolutionary because it closely follows the energy performance of the building during its entire lifecycle (from design to operation, planning strategies for the end-of-life reuse of building components), improving the decision-making strategy for optimising the electricity and thermal energy use.

The project will achieve this purpose by delivering highly replicable user-centric, advanced and interoperable solutions that are adaptable to a wide range of residential buildings. It is based on innovative solutions with a high scalability and replicability potential that: i) ensure the best package of interventions to be applied to make the house energy positive; ; ii) integrate active and passive strategies with smart management technologies through a dedicated BIM environment; iii) investigate innovative routes for promoting minimum environmental impacts; iv) increase the interest and the acceptance of occupants/building owners; v) facilitate the financial feasibility of the interventions.

It will use building and technologies modelling, dynamic BIM models, post-occpancy evaluation, co-financing strategy and circular economy approaches. The ultimate goal of the project is to facilitate projects implementation, enhance faster transition to PEDs, and foster energy efficiency and RES, achieving savings of 146 kWh/m2/year (amounting to about 29.1 Euro/m2/year saved in energy bills and 15.4 kgCO2 eq. /m2/year) and reducing the performance gap by up to 80%.

One of the demo sites, a multifamily residential prefabricated building will be located in Pécs, Southern Hungary.

ABUD is leading Work Package 5 within the project, titled ’Implementation, monitoring and validation in the pilot sites,’  and also focuses on integrated building design, occupant comfort, operation performance and nature-based solutions.

This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement no. 6180833.
