current target to decrease the energy consumption of buildings is important as the
residential sector consumes a significant part of the energy over the energy
chain. Another driver is to reduce greenhouse gas emissions to tackle global
warming. Renewable energy sources and technical solutions should play the main
role in this pursuit. In this paper, a zero-energy log house in southern
Finland is analyzed in detail. The analysis consists of the design, construction,
and practical use during the years 2017–2019. The objective of the study is to
show that a highly energy efficient log house can be achieved in Nordic
conditions without additional insulation by utilizing renewable energy sources
and energy technical solutions. The
energy efficiency of the house is clearly higher than defined in the national nearly zero-energy
building (nZEB) regulations. The house has a plus energy classification and
carbon negative emissions for the energy. The operational cost of electricity
is on both sides of zero.
