Energy efficiency is an important matter that must be taken into account from the beginning of a construction project. A key factor in terms of energy efficiency hinges on airtightness. A properly designed and built log house is extremely well sealed.
We interviewed Jukka Rintamäki, our Product Development Manager, concerning the construction of an energy-efficient log house. In this blog, our expert describes the factors that contribute to the energy-efficiency of a house.
What makes a new house energy-efficient?
The energy efficiency of a building is affected by a number of factors, ranging from the use of energy-efficient domestic appliances to the selection of heating method. Of course, with regard to energy-efficient houses, overall energy consumption must be low – and this can be achieved by means such as the following:
- Design of premises:
Design the building for your specific needs, avoiding any excess square metres and cubic metres to heat.
The structures should be well insulated.
- Windows and doors:
Select well-insulating windows and exterior doors.
Build the exterior wall of the house as airtight as possible by using high-quality sealing materials and performing the work carefully.
- Ventilation unit:
Select a ventilation unit that has a good annual heat recovery capacity, meaning that the unit can effectively recover heat from the exhaust air and use it to heat the supply air.
- Selection of heating energy:
Select a form of heating energy that is inexpensive and based on renewable energy, such as geothermal heat, a water-air-heat pump or an exhaust air heat pump.
- Solar panels:
Use solar panels to create your own electricity.
- Interior structures:
Use plenty of heavy mass in interior structures, such as intermediate walls made of logs. They can absorb thermal energy created by the sun (thermal mass), which is particularly important during times of the year when the sun is low.
- Home appliances:
Select energy-efficient household appliances.
Select energy-efficient LED lamps for lighting.
A log house is naturally energy-efficient and airtight
It is sometimes claimed that log houses are draughty. A Honka home is also an ecologically sustainable choice due to its high energy efficiency; solid-wood logs even out temperature variations, which saves energy throughout the building’s life cycle. When a log is said to breathe, this does not mean that air flows between the logs – on the contrary. The more airtight a log house is, the more energy-efficient it is.
Honkarakenne has been cooperating with various research institutes for decades in exploring matters such as energy efficiency. With the modern solutions we have developed, we have significantly improved the energy efficiency of log houses.
In independent tests, Honkarakenne’s homes built with non-settling logs have proven to be highly airtight and energy-efficient.
Here are a few of the solutions we have patented:
Advanced jointing solutions and highest-quality sealants
We guarantee that your log house frame will be airtight, thanks to our advanced corner-joint solutions and by using the best sealing products on the market. We have developed a specific sealing technique used around windows and doors. Measurements demonstrate that Honkarakenne’s log houses have excellent q50 airtightness values, as low as 0.3 m3/(m2h). Any measurements below 0.6 m3/(m2h) are rated in the best A-category in terms of airtightness.
Honkarakenne lamellar logs
Solutions we have developed can make houses built with both our non-settling lamellar logs and traditional lamellar logs very airtight. This is due to our design work, modern production technology and quality assurance, and the high level of our construction partners – resulting in an energy-efficient solid-wood homes with fine details.
If you like, you can choose a Honka home with extra insulation, reaching an energy efficiency class of A or B. Independent studies have confirmed the highly functional nature of these structural solutions with extra insulation.
Honka’s Environmental Promise
We are committed to:
- Using only Finnish pine from sustainably managed forests
- Ensuring the ecological integrity of our entire production process
- Ensuring the energy efficiency and longevity of our log homes and their environmental friendliness
- Continually working to improve our environmental responsibility
Our vision of sustainable construction
We need a value debate on domestic construction. In too many cases, tight schedules and the pursuit of quick profits win over quality, reason and reflection. What if the key issues were health, a long service life, Finnish origins, the environment, and future generations?READ MORE
