I know for me, I am continually looking for ways to waste less energy, investigating and pursuing ways to seal up my house to keep the hot/cold air that I have just paid a premium to make, either from my furnace, boiler or air conditioner. you can have a high efficient appliance and make the energy in the most cost effective way possible but if you have holes in your home you are literally blowing your money right out the walls.
The good news is that we have developed some great technologies that are allowing us to tighten up our homes, and even getting to the point where we can reach a net 0 home. Net 0 means that your home creates as much clean power as it consumes. Pretty amazing.
The issue we run into with sealing up our homes so tight, is that now we have created little mini environments that can be polluted and our homes don’t have the natural processes in them that our earths environment has to deal with particles, gasses, organics, virus’s. This means more sickness and people with increased symptoms from allergies.
