Endless communication is made possible in today’s world with smart devices, cell phones, and even appliances that are all Wi-Fi enabled. The cultivation of advancement in technology means that we are constantly bombarded with exposure to radiofrequency radiation. This radiation can cause a wide variety of symptoms & health concerns; even cancer. A person spends around 90% of their lives indoors; we need to reconsider the framework of the building envelop as the primary source of protection to minimize the effects of RF radiation.
Health Consequences of Radiation Exposure:
To ignore the dangerous effects of radiation and its link to technology is to be ignorant of the reality of its effect on our biology. Thoma Holz100 is a building system that was developed using innovation in engineering technology and ancient wood doweling. Harnessing the knowledge of moonwood and its benefits on the properties of wood – Holz100 provides inhabitants with a building shell that is made of pure solid wood; without glues, chemicals, or toxins. The moonwood used in Holz100 has been tested to block high frequency mobile phone radiation better than reinforced concrete, bricks or other commonly used prefabricated systems.
As part of a study of the Thoma Research Center in Goldegg, more than 100 different building materials and their combinations were tested at the University of the Federal Armed Forces in Munich for their attenuation for technically generated, high-frequency waves. During the measurement, it was examined how much of the emitted power penetrates the test specimen.
The result provided the best values for thick wooden walls!
Damping testing values show Holz100 can offer 99.9% protective attenuation up to 60dB, at a frequency levels up to 80GHz!
Contrary to expectations, the building material wood - tested in the form of non-glued, fully solid Thoma Holz100 walls - shields much better than, for example, brick variants or lightweight construction systems.
Here are the damping values of a 17.6 cm thick Thoma Holz100 wall:
At 900 MHz (D-Net), only 25% penetrate through the wooden wall
At 1800 MHz (E-net), 10% penetrate through the wooden wall
At 4 GHz, only 1% penetrate the wooden wall
Starting at 6.5 GHz, less than 1 per thousand penetrate through the wooden wall
(According to measurements of the University of the Federal Armed Forces Munich, Department of Electrical Engineering, Werner-Heisenberg-Weg 39, 85577 Neubiberg, Germany)
Why should I care about fire safety?
Your home is more prone to fire than you think.
According to NFID, there was a total of 38,844 fires in the seven jurisdictions reporting in 2014. Of the 19,062 structural fires reported in 2014, three quarters (74%) were residential fires. Consistent with the overall trend, the number of structural fires declined by 26% between 2005 and 2014. However, Over the 10-year period, residential fires consistently accounted for 6 out of every 10 structural fires, ranging from 69% in 2005 and 2006 to 75% in 2013.
Although the overall number of reports have decreased, why did the proportion of residential and structural fires increase?
Because newer homes burn faster:
"Research shows that 30 years ago, you had about 17 minutes to escape a house fire. Today it's down to three or four minutes. The reason: Newer homes and the furniture inside them actually burn faster. A lot faster.
"Among structural residential fire incidents, cooking equipment and smoker’s equipment/open flame were the two leading sources of ignition in residential fires over the 2005 to 2014 period. These two categories combined consistently accounted for about 6 in 10 of all of the residential fires." - NFID
"The majority of fire-related deaths occur in structural fires. For example, in 2014, 87% of the reported fire deaths occurred as a result of structural fires. Vehicle fires accounted for 11% of reported deaths, while outdoor fires accounted for 4%." - NFID
People are innately drawn towards wood.
When Planet Ark presented survey participants with images of two rooms, one furnished with a wooden chair, desk, blinds and other items made from wood, while the other showed the same items made from plastic (shown on the right), two out of every three people said they preferred the wooden room.
This result occurred despite one in two people saying they were completely unaware that wood had associated health benefits.
The images were taken from a study by David Fell (2010), which emphasized how Canadians have similar innate attitudes towards wood as well.

- Bergs, J. Effect of healthy workplaces on well-being and productivity of office workers. in (2002).
Table 1 (on the left) highlights the positive associations that wood induces in people, where an overwhelming 96% agreed that wood is ‘visually appealing’ and ‘has a natural look and feel’. Eight out of ten people also thought that wood is versatile, recyclable, renewable and long lasting. They appear to be less aware of the environmental benefits of wood, with only six out of ten survey participants understanding that wood stores carbon and creates less carbon emissions during production than steel and concrete.
The positive views of wood continue even when compared to other material types (Table 2). Wood was viewed as the material that creates a natural look and feel, warm and cosy environments, is visually appealing and is nice to touch by nine out of ten people, and as being the most environmentally friendly by seven out of ten people. By comparison the second most popular material, brick, received an average of 34% less positive feedback. Plastic was seen as the cheapest material but it also scored lowest in four out of five categories related to creating pleasant surroundings and being environmentally friendly.
These survey results provide support to the empirical evidence discussed above. Even though many people don’t understand the health and wellbeing benefits of wood they instinctively react to the feelings of warmth and comfort it creates and its natural look and feel. An increasing body of research is beginning to show that being surrounded by wood at home, work or school has positive effects on the body, the brain and the environment.

So it is important to know that not only does it fulfill ideal building standards, it also brings its habitants an amazing environment of health and wellbeing. Here are three studies that prove the health benefits of wood on the body:
A Japanese study compared the initial physiological response of 14 people sitting in rooms with either wooden or steel wall paneling. The pulse and heart rate of each subject was measured every second for 20 seconds whilst facing the paneled wall covered by a curtain, followed by 90 seconds with the curtain removed and the wooden or steel panel visible. The study found that exposure to wooden panels significantly decreased the blood pressure of subjects, whilst exposure to steel panels significantly increased it.
Sakuragawa, S., Miyazaki, Y., Kaneko, T. & Makita, T. Influence of wood wall panels on physiological and psychological responses. 51, 136–140 (2005).
An Austrian study examined the heart rates of 30 people who slept in a Stone Pine bed for 3 weeks and compared it to their heart rates when sleeping in a wood imitation bed for 3 weeks. Sleeping in a stone pine bed reduced heart rates by 3500 beats per day compared to when subjects were sleeping in a wood imitation bed.
(Joanneum Research Institute of Non-Invasive Diagnosis)
A yearlong Austrian study examined 36 high school students aged 13-15 years old who were taught in either a classroom furbished with floors, ceilings, cupboards and wall panels made of solid wood, or a classroom equipped with a linoleum floor, plasterboard walls and chipboard cupboards. The results showed significant differences between the two groups, with students taught in the wooden classrooms having decreased heart rates and decreased perception of stress from interactions with teachers. In contrast, students taught in the control classroom had increased heart rates and had greater stress responses.
Kelz, C. & Moser, M. . (Medical University of Graz, 2011)
Wood is one of the oldest materials used by humans, including its use as a building material. Wooden furniture and funereal items have been found in the pyramids of Egypt and some structures built centuries ago are still standing today. These include the Horyuji temple in Japan built in 700 CE, Greensted Church in England built in 1053 CE and Westminster Hall in London built in 1399 CE.
Although wood has ancient roots and has been used in every culture in the world from before the Stone Age it is experiencing a revival in use. In part this is because of the newly discovered health and wellbeing benefits of exposure to wood, which produce similar effects to those created by spending time in nature.
These known benefits include:
• Increased happiness and self-esteem levels
• Increased cognitive abilities
• Decreased stress response, blood pressure, pulse rates and cholesterol levels
However, increasing urbanization rates mean that people have less access to nature in their daily lives and Americans on average now spend about 90% of their time indoors. This coincides with reports of increasing levels of obesity and many experiencing a mental health condition within their lifetime. As it is not always possible to increase our time spent outside, particularly in areas like workplaces, schools and hospitals, understanding how to incorporate the physiological and psychological benefits of nature into our indoor environments is an increasingly important area of research.
Studies have demonstrated that simply having a view of nature from a window can have significant positive effects, such as shorter postoperative hospital stays, induced feelings of relaxation in patients at rehabilitation centres and improved comfort levels of employees in offices. Not surprisingly, the presence of indoor plants has also been shown to have benefits, such as improved cognitive functioning in office environments, increased tolerance of pain in hospitals, lowered blood pressure and heart rates.
Evidence-based design (EBD) is an area of study that focuses on incorporating the results of empirical research into the quality of the built environment. Originating from the field of environmental psychology, EBD works on the notion that the design of the built environment fundamentally impacts the people within it. Of particular interest are designs of physical features that can lead to stress-reduction, productivity and general wellbeing. Since evidence shows viewing nature in both outdoor and indoor settings has health and wellbeing benefits for people, it is logical to examine whether wood, a natural material, produces similar effects.
A New Age of Quality Timber Construction
Living in a Natural Wooden House
My Holz100 Home
Enrich Life with Wood
About the Residence:
The house is located in one of the most attractive locations in Aarberg directly on the Hagneck Canal overlooking the Chasseral. The family house is designed for a family of four to six. The house has the living rooms on the ground floor and the bedrooms upstairs and is fully built on a basement.
The special feature of the house is that it is built in Holz100: a glue and toxin free solid wood construction. With 30 cm thick solid wood walls with a large storage mass, solid wood parquet and wooden doors, this house radiates a lot of warmth and security. Also the z. T. plastered wall surfaces were created with a natural material, a fine lime plaster.
The house is heated only with a wood stove on the ground floor and the radiant heat is distributed throughout the house.
The material and the heating provide the residents with a healthy and comfortable living environment, which is energy-saving and sustainable for future generations (circular economy).
The impairment of the quality of life through noise is a disruptive factor that affects many people. Noise disturbs the well-being, the ability to concentrate and the communication. Typical consequences of continuous noise are limited performance and a higher susceptibility to disease.
In the case of a new building, considerable protection against noise pollution can already be effected in the planning phase without additional expenditure. Acoustic windows are only part of the measures. The highest degree of protection is achieved when choosing the right building fabric. Prefabricated houses in lightweight construction offer only low noise protection and brick or concrete walls are sometimes even very good (ie harmful) "sound bridges". The best solution is provided by solid wood - provided that it is processed correctly. Solid wood is the best natural sound or noise insulation.
In the past, wooden houses were considered to be clairaudient - and almost everyone can tell an amusing anecdote about thin hotel walls. Thanks to the Thoma Holz100 walls, which have been awarded numerous innovation prizes and certificates, the exact opposite can now be experienced. Wood becomes the building material for the most peaceful recreation homes. In Längenfeld / Tyrol (pictures below) is probably the quietest wooden hotel in the world - the Waldklause. Here, a sound insulation was measured, which is twice as high as the standard values of Europe demand.
The supply of the commercial park completed in 2010 with a usable area of 6,500 m2 takes place with an active energy balance over the entire year. The surplus energy is used among other things for the operation of electric vehicles. The total annual energy consumption is about 209,000 kWh. The total yield is currently 226,750 kWh.
The ARCHENEO is the first energy-autonomous solid wood building with zero grams of CO2 emissions in Austria. This is achieved without loss of comfort for the users. The active house is made of native, moonwood completely ecological - without adhesives, glues or chemicals. The building is built from 36.4 cm thick Thoma Holz100 elements and grows again in Austria's forests in 42 minutes. The project makes a valuable contribution to raising awareness of the changeable and ever-renewable resource wood.
For a high-quality mix of innovative companies from the ecological, social, innovative-technical as well as health and wellness areas, there is also space for other companies in addition to existing companies, which profit from the synergy of the overall concept.

Valuing Creation with Wood
Over 1,000 Healthy Homes Around the World
1. Protect the building materials and construction from rain and moisture.
A wide enough roof overhang prevents direct contact with rain and is more effective than any treatment. Old, wooden buildings always have a wide roof overhang to protect external walls and cladding.
Keep wood off the moist earth. Cladding and posts should never end up in the ground or soil. Make sure you build on sufficient foundation made from brick, concrete or rock.
Weather boards are to be installed onto a slatted frame allowing free air movement and circulation to wooden building components.
Condensation, Frost and Foils:
It is important to ask professional tradespeople about all types of insulation. Ask them to calculate the dew point for every ceiling and wall construction and to confirm their results in writing. At a later point a vapor retardant might get injured and cause damage. The best solution is a solid, homogenous wooden wall like the Holz100 system presents. Here the vapor pressure is continuously slowed down instead of suppressed by a single, vulnerable layer of foil and guarantees 100% protection from condensation moisture and fungus.
To constructively protect your building, you need a tradeperson who appreciates this type of work. Luckily those kind of people do exist and their numbers are rising.
2. Be aware of water transportation by dry rot:
How to prevent dry rot? If the house has been built in a constructive and proper way, it usually is enough to make sure there are no rotting piles of wood, old building parts or off cuts which provide feeding and breeding ground anywhere close to the building.
When restoring the building, all infested wooden components should be generously removed and any existing strands of fungi should be eliminated from the masonry, brick and stone work with a blowtorch.
Realistically, in all the years of our professional building work, we never came across any dry rot in wood which has been dried, stored and worked with properly.

'Eckhart Tolle Reveals How to Silence the Voices in Your Head' in OPRAH
“Look at a tree, a flower, a plant. Let your awareness rest upon it. How still they are, how deeply rooted in ‘just being’. Allow nature to teach you stillness. When you look at a tree and perceive its stillness, you become still yourself.” – Eckhart Tolle, one of the greatest spiritual leaders of our time
HEALTH – YOUR GREATEST INVESTMENT
We don’t notice right away, but why do we get headaches and feel dizzy or suffocated in large stores or new buildings? The reason is simple. According to EPA, “Americans, on average, spend approximately 90% of their time indoors”, where “concentrations of many VOCs are consistently higher indoors up to ten times higher than outdoors… VOCs include a variety of chemicals, some of which may have short and long-term adverse health effects”. Conventional building materials pollute the air we breathe with dust, VOCs, allergens, and off-gassing due to chemicals, toxins, glue/resins, paint, varnishes, stains, and so much more that we do not see but feel over time.
A long-term exposure to hidden toxins induce stress and can trigger serious stress-related health consequences, including obesity, type 2 diabetes and related cardiometabolic complications. Three of the ten top causes of death in the U.S. include cardiovascular disease, cancer, dementia or Alzheimer’s disease correlated to long-term exposure to such environments are exactly the ones minimized by wood. During sleep in a pure wooden home, the heart rate slows down so that a person saves 1 hour (3,000+ heartbeats) a day and reduces overall stress - as if you were sleeping in a forest.
BUILD WITH WOOD
Do you know about the various associated health benefits of wood? Based on extensive research ("Make it Wood" by Planet Ark), numerous independent studies taken all over the world clearly demonstrate that the presence of wood has positive physiological and psychological benefits that mimic the effect of spending time outside in nature.
For example, wood improves your emotional state by increasing levels of happiness, self-esteem, cognitive abilities and self-expression while reducing blood pressure, pulse rates, cholesterol and stress levels.
Using wood in schools and daycares reduce exposure to stress during childhood and adolescence which decreases the probability of stress-related mental disorders later in life. Natural wood in hospitals and senior’s homes increase interaction, engagement, positive self-expressions elicited by the feeling of warmth, comfort, and relaxation which reduces stress, anxiety, risk of dementia and recovery time which shorten hospital stays, therefore reducing medical costs. Within commercial or corporate environments, the presence of wood drastically influences first impressions as it conveys feelings of innovation, energy, comfort, and improved productivity. Most consider wood to be visually appealing, has a natural look and feel, and is more versatile, recyclable, renewable and long lasting compared to brick, concrete, steel, aluminum, and plastic.
Not only do wooden living spaces improve its residents’ emotional, mental, and physiological state, but responsibly sourced and certified timber is also a formidable weapon in the struggle against climate change by both storing carbon and eliminating emission.
Contrary to the great misconception that wood cannot be fireproof, heavy timber construction has an inherent level of fire resistance which increases with thickness as the outer layer chars and becomes a protective insulation layer that slows down the burning rate. The strength and load carrying capacity is not as compromised as steel which buckles under extreme heat due to its significantly higher thermal conductivity and allowing heat to spread rapidly, causing beams and floors to collapse.
