Objective: Promote the development of sustainable construction in Latvia and contribute to Latvia’s energy efficiency goals in the field of construction by developing a new concept for the construction of low-energy multi-storey residential buildings, which includes the use of ecological, intelligent and energy-intensive construction materials for delimiting and bearing structures, as well as energy efficient, active and/or passive engineering systems. Keywords: Sustainable construction, building life cycle, energy efficient, smart materials, cement composite, light constructions, recycling. Within the framework of the project it is planned to carry out industrial and experimental studies – development and optimisation of the building’s constructive elements solutions, using intelligent and ecological building materials developed in the laboratory and industrially approbated: Efficient and ecological delimiting materials (natural fibre composites and nanomodified foam), high-performance cement composites with innovative dispersal reinforcement, high-performance thermal energy-saving cement composites with indoor temperature control properties. In order to create structural prototypes, it is envisaged to optimise the composition of innovative materials and the structures and connections created from them. Within the framework of the project, it is planned to appraise the production methods of construction materials developed in the laboratory under the conditions of production and to manufacture prototypes of building materials from them. The designs are to be integrated into multi-storey residential buildings in the 3D model, which will be used in calculations of the energy efficiency of the building. As a result, it is planned that the materials and constructions used in the new concept 3D model will promote efficient/economic use of energy resources both in the heating and summer season, in order to ensure the indoor climate suitable for human well-being. The building’s improved energy efficiency will be ensured by intelligent engineering systems: Optimally designed heating, ventilation and air conditioning systems to ensure a microclimate favourable to human health and ability, the efficiency of which will be enhanced by intelligent materials and structures used in building construction. In order to demonstrate that the new concept meets the basic conditions for sustainable construction, the calculation of the energy consumption balance and the analysis of the life cycle of the building will be carried out. The intellectual property rights to the construction solutions developed within the framework of the project are to be strengthened by filing 2 patent applications and concluding intellectual property licence agreements within five years after the end of the project.Project classification according to the OECD Field of Science and Technology (Revised Field of Science and Technology): 2. Engineering and technology (2.1. Civil Science, 2.5. Material science, 2.7. Environmental science). The main activities of the project are industrial and experimental research (20 %) using both the scientific organisation and the infrastructure of the partner. The project also provides for awareness-raising activities for the target group. The project is a non-economic cooperation project – the cooperation with the partner is based on the results of scientific research carried out by the scientific institution and the acquired knowledge, as well as developed production methods to appraise the production of intelligent construction materials and structures in the plant using the infrastructure of the cooperation partner. The developed prototypes will be tested and the obtained data will be used in the calculations of the energy efficiency of the building, but will not be used for commercial purposes.The total cost of the project is EUR 648648.00, of which ERDF support is 85 % (EUR 551350.80), the rest consists of the state budget (7.5 %). EUR 48648.60 (funding from the ERDF and the state budget in total is EUR 599999.40) and co-financing by Project participants (7.5 % EUR 48648.60). The planned duration of the project is 36 months.
