In this data article, we present a supplementary dataset from a zero-energy log house project in southern Finland, presented in detail in [1]. This article consists of comprehensive energy-related data collected in practice from several sources from the house during the period of 2017-2019. The data include solar PV production data of two separate systems, in south and east-west directions. The solar PV data are presented on a different time scale to demonstrate the operation of two installations in different seasonal conditions. Simulated results are also included. The electrical energy consumption is distributed between the consumer, ventilation, the ground source heat pump for space heating and the domestic hot water energy at the monthly level. The realized electrical energy prices, self-sufficiency rates, and costs are also presented at the monthly level. The heat production of the ground source heat pump is estimated according to the service hour data and the performance data given by the manufacturer. The data can be applied in new and building-under-renovation projects.
