Abstract

In the construction domain, the energy represents the key-point in achieving efficient buildings. The project proposes the improvement or institutional performances between three universities and two research institutes for the revival of the research activities and transfer of knowledge between partners.

The 4 proposed projects, centred on the efficient energy buildings, are focused on two principal research directions: (i) use of smart facades with low-thermal transfer, actively integrated for the enhancement of internal comfort and possessing a passive control of energy (by using the solar energy) and (ii) smart energy efficiency through building automatization and solar energy collectors. The resulted system, the smart house, is conceived thus to minimize the input energy for maintenance.

Project 1 has as main objective the determination of mechanical properties of cellular materials used as thermal insulations in smart façade systems, through mechanical compression, bending and toughness fracture testing of such cellular materials.

Project 2 is focused on obtaining, characterizing and testing of high-property materials used for smart facades as thermal insulation materials and as support for special property layers: photo-catalytic layers and with reduced absorption/reflexion of UV-VIS-IR radiation.

Project 3 has as main objective the theoretical and experimental investigation of the implementation of the electric power distribution in direct current for individual households or in small communities (smart-grid), with renewable energy sources integration.

The scope of Project 4 is to implement the knowledge and data resulted from projects no. 1-3 through a modular laboratory demonstrative application. The project will perform an integrated study on the influence of the facades and the energetic contribution to the internal comfort of the building by considering different façade systems and respectively by integrating a smart-grid energy system.

Objective

The main objective of the project is the improvement or institutional performances between the three universities and the two research institutes for the revival of the research activities and transfer of knowledge between partners. The specific objective of the project is centered on the increase of energy efficiency of buildings, realized by the use of smart facades with low-thermal transfer and smart energy efficiency through building automatization and solar energy collectors.

Results

  • Determination of mechanical properties of cellular materials used as thermal insulations in smart façade systems.
  • Production, characterization and testing of high-property materials used for smart facades as thermal insulation materials and as support for special property layers as:
    • cellular glass and different sponging materials;
    • composite materials with natural and synthetic fibers with high mechanical resistance, fireproof character, good thermal insulation, resistance to frost/thaw cycles and exposure to solar radiation;
    • materials with photocatalytic properties based on TiO2 and WO3 used for the degradation of pollutant components from the ambient air;
    • materials with reduced absorption/reflexion of UV-VIS-IR radiation.
  • Implementation of the electric power distribution in direct current for individual households or in small communities (smart-grid), with renewable energy sources integration, finalizing with an experimental platform, with:
    • development of soft and hard models (HIL), configurable, for parts of the network, which will be integrated into the experimental model (sources of renewable energy, electric charges, distributed control systems and energy management-SCADA), so that the experimental platform may be capable to respond to extensive tests, preliminary to some implementations at the industrial level;
    • integrating some elements of conversion (static converters) and energy storage, with original structure, with appropriate analysis of stability of decentralized control systems, intended for implementation of the energy management;
    • development of computer-aided procedures, regarding conducting real-time energy balances in both the components and the entire system of micro-network.
  • Modular laboratory demonstrative application for the implementation of project results, realizing a global study regarding the influence of the facades and the energetic contribution to the internal comfort of the building, by considering different façade systems and respectively by integrating a smart-grid energy system. Results will follow mainly the optimization of interior comfort conditions as: temperature, humidity, indoor air quality and the efficiency of energy consumption by integrating a smart-grid system. Smart-grid system will achieve the efficiency of internal users of electricity (ventilation, cooling, etc.) and energy storage.
