SMART WOOD BLOG

Welcome! Here we talk about wood, building and everything around it! 

In this video you’ll find information with visual examples about what are the differences between timber frame and log house!

Buildings have a significant contribution in the overall energy consumption in the EuropeanUnion (“EU”) by about 40%. For this reason, the EU has issued specific directives to member states related to the Energy Performance of Buildings and the use of renewable energy in buildings. Cyprus has embedded into national law the aforementioned directives, by taking various measures, such as issuing relevant decrees (Federation of European Heating, Ventilation and Air Conditioning Association).


U-value or thermal transmittance (reciprocal of R-value) is the rate of transfer of heat through a structure (which can be a single material or a composite), divided by the difference in temperature across that structure. The units of measurement are W/m²K.


Well-insulated parts of a building have a low thermal transmittance whereas poorly-insulated parts of a building have a high thermal transmittance. Losses due to thermal radiation, thermal convection, and thermal conduction are taken into account in the U-value. Although it has the same units as the heat transfer coefficient, thermal transmittance is different in that the heat transfer coefficient is used to solely describe heat transfer in fluids while thermal transmittance is used to simplify an equation that has several different forms of thermal resistances.


Minimum requirements of 2016 (Κ.Δ.Π. 119/2016 και Κ.Δ.Π. 379/2016) In effect from 1.1.2017


Walls maximum U - value: 0.4 W/m2 K Walls can be up to 0,6 W/m2K if windows up to 2,5 W/m2K


Roof and floor in contact with external environment maximum U - value: 0.4 W/m2 K


Floor above closed unheated spaces maximum U - value: 2.0 W/m2 K


Window maximum U - value: 2.9 W/m2 K

In a world where people are spending more and more time at home, it is essential to create an environment around you that keeps you productive during the day and relaxed in the evening.


Wood buildings have been around for centuries and the benefits of living in them have been researched for quite a while now.


We have gathered the main points that explain why wood houses are better for health.


  • Wood is soothing, aesthetically pleasing, and performs well acoustically. It absorbs sounds and creates a calming, relaxing atmosphere.


  • Log buildings naturally promote good health. Solid wood has the unique ability to absorb moisture and release it back into the air as the room dries. This balances the indoor air humidity to a level between 30 – 50 % which is optimal for the health of the people living inside.


  • Numerous studies have demonstrated that environments with wooden structures lower blood pressure and heart rate and induce feelings of relaxation. It seems that wooden environments reduce stress, just like walking in the woods.


A classroom study conducted in Austria showed that a solid wood classroom could positively affect the mental and physical health of children. In this study, students in the solid wood classroom were demonstrated to be healthier, calmer, and less stressed than those who studied in traditional classrooms. The tests, which took place over a period of more than a year in Ennstal, Austria, involved two classrooms with massive wood walls and two traditional classrooms for comparison. Scientists from Joanneum Research measured the students’ pulse. The average pulse rate of the students in the classrooms with massive wood walls was lower than that of the students who studied in the traditional classrooms by 8,600 beats per day. This comes down to approximately 6 beats per minute. The study also concluded that the children were more relaxed at home after school and their powers of recovery were far greater (Human Research Institut).
