Dataset from the zero-energy log house project

Area of Science:

• Building Science
• Renewable Energy Systems
• Sustainable Architecture

Background:

• The increasing demand for energy-efficient buildings necessitates real-world data on their performance.
• Zero-energy buildings aim to minimize operational energy consumption and environmental impact.
• Understanding energy dynamics in residential structures is crucial for optimizing design and operation.

Purpose of the Study:

• To present a comprehensive dataset from a zero-energy log house in southern Finland.
• To provide detailed energy-related data covering solar photovoltaic production, electrical consumption, and heat pump performance.
• To facilitate research and development in sustainable building technologies.

Main Methods:

• Data collection from multiple sources within the log house from 2017-2019.
• Recording solar photovoltaic (PV) production from two distinct systems (south and east-west facing).
• Analyzing electrical energy consumption (consumer, ventilation, ground source heat pump) and heat production, alongside energy prices and self-sufficiency rates.

Main Results:

• Detailed monthly data on electrical energy consumption, including breakdowns for different house systems.
• Solar PV production data presented across various time scales to illustrate seasonal performance variations.
• Monthly data on realized electrical energy prices, self-sufficiency rates, and associated costs.

Conclusions:

• The presented dataset offers valuable real-world performance metrics for a zero-energy log house.
• The data can inform the design and renovation of energy-efficient buildings.
• This supplementary data supports further research into optimizing renewable energy integration and energy management in buildings.
