Are electric cars truly zero emission? What if you knew these vehicles are coal-powered?
Reality is an absolute scale. … But people still don’t understand the simple fact that perception is different from reality, and that everyone has their own perception of the world. Everyone thinks their perception is reality. So, there become millions of realities, when in fact there was only one. – Paul King, Director of Data Science at Quora, Computational Neuroscientist, Entrepreneur
Government specifications require the application of various products and practices touted as ‘green’, ‘energy-saving’, etc.
Does foam insulation save energy? Yes, if applied with other sensible things. My attic is never hot, never more than one degree F above the warmest zone in the house.
Newer homes are most often required to have high R-value insulation, vapor wraps, and energy-efficient windows. Check. Due to the inherit sealed nature of structures constructed with these features, ventilation can and most often is an important challenge. The solution is typically the energy-recovery ventilator, a heat exchanger for which the intended purpose is to minimize loss of heating or cooling energy to the atmosphere while diluting the indoor air with fresh air.
The solution is typically the energy-recovery ventilator (ERV), a heat exchanger for which the intended purpose is to minimize loss of heating or cooling energy to the atmosphere while diluting the indoor air with fresh air.
Home builders incorporate the ERV into new homes across the fruited plain. Often the homeowner will discover he or she cannot cool the space in the summer time. The homeowner calls an air conditioning service company to check out the HVAC system and the A/C tech experimentally discovers switching off the ERV solves the problem.
But, the ERV is green. Right? Yes, when properly applied and scientifically calibrated they are very effective. From my own professional experience, ERVs and electronic air cleaners eventually are switched off, not because they can’t work, but because the whole body of knowledge hasn’t been considered.
The first to speak in court sounds right— until the cross-examination begins. – Proverbs 18:17 NLT
Truth is the way things truly are. Don’t place all your eggs in a perception basket. Learn all the facts before plowing your money into a false reality.
