the highway bridge is the cause of the humming
For months Roland Wernstein (Germany) examines an annoying buzzing sound in his neighborhood: the heating system, bass from the neighborhood, truck engines, vibrations caused by rail or air traffic were suspected, but were rejected. The end of March 2016 he took time for the facts check: the humming was heard only at night and when the wind from the southwest, recalled a distant diesel engine running and had short, miscellaneous long interruptions.
Now the girl is sleeping well
Sometimes solutions can be quite simple. The parents turn the wireless router off at night and the two year-old daughter sleeping since then through again. The background: Susanna Rubin was with the nerves at the end. Her child woke up in the master bedroom at night nine to ten times screaming. If the family stayed away from home, there was no trouble sleeping. The building biologist initially investigated the area of the bed. There were a few little things to correct. For example, the low-frequency alternating electric fields could be eliminated almost entirely by turning off a circuit. For the electrostatic charging of the bed surface, there was also a solution. The main problem for the sleep was not to be found right in the bedroom.
Expert measures with magnetometer
For investigation of sleeping areas, the main concern of the region is below the bed. In a particular case the building biologist found the problem not only on the ground, but primarily at the head of the sleeping quarters. What happened? Manfred Eberlein was not sleep at night after moving into a new apartment in the city center. In the old apartment he slept like a log. A dowser had already changed the roost some eight weeks before. However, this action was not successful.
Example of a LED light spectrum
A low power consumption is not the only criterion
Everyone wants to make an active contribution to climate protection and save energy. To achieve this goal, we can use energy saving devices and energy-saving bulbs in the household. But a low power consumption is not the only criterion when we select an appropriate lighting. Scientific studies have confirmed the importance of natural light to our health now detected. Daylight is optimal for our well-being. It has a harmonious color spectrum (red, green, blue) and a low UV component. The conventional light bulb came the natural color spectrum very close. Only the red component was somewhat increased. Even the light from halogen lamps largely corresponds to the natural spectrum. Another advantage of conventional light bulbs and halogen bulbs is a uniform flicker of 100 Hertz and a small proportion of flickering light.
Sebastian Merkner went only reluctantly to his office. The self-employed carpenter completed Saturdays always his bills because he could then work undisturbed by the daily business. After a few hours in the room he was nervous and felt like charging. Then there were the headaches and eyestrain. The relationship between the office environment and the discomfort was obvious. Merkner went through the possibilities in his head: Was the beams of the wooden ceiling painted with wood preservatives? Escaped from the formaldehyde glued bookshelf? Was the mastic asphalt under the floor covering of the culprit? The master craftsman brooded for months after the causes of his symptoms.
be vigilant against elektromagnetic fields at work
An employee of an engineering company complained for months about eye problems. In the Eye Clinic Robert M. was tested among other things, a sensitivity to electromagnetic fields. In fact, increased intraocular pressure, after a field source has been turned on in his surroundings. After this diagnosis, a building biologist made on the search for the problem. His order was: reduce electromagnetic pollution in the office.
do research carefully before painting the room
Vincent Kuchler (Stuttgart/Germany) phoned our advice center yesterday. His eyes were swollen and his nose ran constantly. His suspicions focused on the oily stain on the newly installed floor in the bedroom and children’s room. A doctor for diagnosis of his symptoms he had not yet visited. Vincent wondered, however, why the other family members showed no allergic reactions. How could a piece of advice for those concerned to look like?
be carefull with second-hand-homes
Young families often have too little capital to build a new home. Alternatively, see the potential homeowners to the market for second-hand houses or apartments. In the assessment of “used” caution is advised. It may occur many problems that are not recognized at first sight by the laity.
Rapid Exchange of product-news in the EU
Rapex (Rapid Exchange) is an alert system for dangerous consumer products in the non-food area. 31 European countries and the European Commission shall communicate to the fastest means of information to draw risky products from the market. A weekly report can be subscribed to via RSS-Feed or accessed directly on the website. Those who read the messages carefully, place the emphasis on Chinese products. But also from European countries, including Germany, permanent harmful products to hit the market. Some examples to show where the problem lies mainly:
Dataloggers measure the room climate
– The climatology is one of the most difficult areas of science. Air, temperature and electric climate influence each other more or less – and these factors are in turn influenced indoors of building materials, construction and electrical installation. Although cooperating the individual components of indoor climate, it will be discussed for better presentation separately. Now read which components affect our indoor climate.
