The paper focuses on the experience with research of combined building-energy systems such as energy roofs, ground heat storage and active thermal protection. The EB2020 experimental house was largely designed in accordance with the patented ISOMAX system (SK 284 751, author: Dipl.-Ing., Phys. Edmond D. KRECKÉ), which represents a high potential for the use of renewable energy sources. When designing the experimental house EB2020, we eliminated the problem of this system by designing top heat sources, whose heat sources are exclusively solar and geothermic energy. The investigated building is designed with the following heat sources and energy systems: energy roof, low-temperature gas boiler, fireplace with hot water exchanger, ground heat storage, storage water heat storage with electric reheating, active thermal protection, large-area radiant low-temperature heating / high-temperature cooling, liquid cooling circuit in the ground outside the building, recuperative air handling unit and air ground heat exchanger. In this paper we describe the theoretical procedure for calculating the efficiency of the energy roof, comparison with a classic solar collector, experimental measurements of the energy roof during one season and evaluation of the measured data. The application of an energy roof requires lower investment costs than conventional solar collectors, but experimental measurements have shown that the energy gain and the achieved temperatures of the working substance at the outlet are significantly lower. For higher efficiency energy roof, it is worth considering installing a dark roofing and installing more circuits with a suitable orientation according to cardinal directions. This may be the subject of further research.

本文重点介绍了能源屋顶、地热储存和主动热保护等建筑能源组合系统的研究经验。EB2020 实验房主要是根据获得专利的 ISOMAX 系统（SK 284 751，作者：Dipl.-Ing., Phys. Edmond D. KRECKÉ）设计的，该系统代表了使用可再生能源的巨大潜力。在设计EB2020实验房时，我们通过设计顶部热源来消除该系统的问题，其热源完全是太阳能和地热能。被调查建筑设计有以下热源和能源系统：能源屋顶、低温燃气锅炉、带热水交换器的壁炉、地热蓄热、带电再加热的蓄水蓄热、主动热保护、大面积辐射低温供暖/高温供冷、楼外地面液体冷却回路、换热式空气处理机组和空气地热交换器。在本文中，我们描述了计算能源屋顶效率的理论程序，与经典太阳能集热器的比较，一个季节能源屋顶的实验测量以及测量数据的评估。能源屋顶的应用需要比传统太阳能集热器更低的投资成本，但实验测量表明，能量增益和出口处工质达到的温度要低得多。对于更高效率的能源屋顶，值得考虑安装深色屋顶并根据基本方向安装更多具有合适方向的电路。这可能是进一步研究的主题。
