CO2 as solution for heating, not as a problem

Posted by Tinus de Vreugd in Energy saving No Comments »

CO2 HeatpumpR744 is the refrigerant name of Carbon Dioxide (CO2), and is a natural gas which is all around us. In fact, we cannot live without Carbon Dioxide! As with anything, adding too much CO2 to our environment, while the demand of the natural use from nature, is rapidly decreasing by cutting down forests, also for the use of fire wood and fuel pellets, is becoming rapidly a problem.

On electric adventure to Norway

Zoe rainbow Denmark[Klik hier voor de Nederlandse versie]
Two years ago it was the first time I went to Switzerland with my 100% electric Renault Zoe. 900km one way was a real challenge because back then there were no fast chargers. It made me happy if there was a semi-fast charger (22kW) on the route. This way I could not drive more than 350km per day. The next year there were some fast chargers and it was possible to make an entire tour of almost 2400km through Switzerland.
This year I set the bar higher, and the outward journey is already 2000km! Now I will mostly use fast chargers, and cover 550km per day. Seven different charge cards or phone Apps have been arranged. Hopefully they all will work, because I wasn’t able to test most of them. Furthermore, I will not use ferries on this trip, but drive entirely over bridges in Denmark and Sweden to Geiranger (Norway), where among other things I will attend the 20th anniversary of the Norwegian electric car association.

Infrared panels nearby windows, will the infrared rays pass through them or not?

Posted by Marcel van der Steen in Explanation No Comments »

teaser_infraroodstralingVerliesDoorGlasOfNietInfrared panels are offered more and more as a cheaper (and more comfortable) alternative, compared to central heating, to create an adequate inner climate in your house and rooms. I understand very well the theoretical functioning of these panels and how to create a pleasant in-house climate. However recently have have run into two companies, that sell a lot of infrared panels, telling me that the infrared rays coming from infrared panels do travel straight trough windows, and even that their infrared panel manufacturers do tell them that. This is nonsense to me, and in this article I explain that infrared radiation coming from infrared panels do not travel straight through windows. I will explain that heat (energy) can travel through windows (easier than through walls) but that is a different process.

Lighting for the body, not just for the eyes

Posted by Marcel van der Steen in Explanation No Comments »

sunHealthTo ensure that light is functional in the internal work space, we use for instance the norm EN 12464-1. It describes for different work situations the minimum average illumination values, the evenness, CRI ,UGR and sometimes the color temperature. But light does more. It can have a very positive effect on human’s well being. Norms 67600 and 5031 tell how.
OliNo implemented the measurement of melanopical effectiveness according to these norms.
