Zentek has always understood that the core of the problem is that people are uncomfortable. They use fuel to either cool or warm themselves. If their clothing is making them comfortable in any weather, you take away that need. We need to get over the concept that the building should be the perfect temperature.That is central air. If we minimially regulated a building to 55 F degrees-- easily done with solar. Used thermal regulating clothing, instead, how much energy would we save?
