This story begins in 1973 amidst an energy crisis, kickstarted by an Arab oil embargo, the United States began rationing its energy consumption. Just six months later, the embargo was over. But by then, the price of oil had risen by nearly 300% globally. Accounting for nearly a quarter of the country's total energy consumption. Commercial buildings became a major focus And in 1975, the American Society of heating refrigerating and air conditioning engineers released the first iteration of standard 90. This 53 page document to find fundamental building design standards aimed at increasing building efficiency. Within it was the focus of this video. A small paragraph recommending the use of energy recovery systems. The basic principle of energy recovery and buildings is to transfer energy from one air stream to another. Some systems can only transfer heat while others can transfer heat and humidity. We call them energy recovery ventilators or E R V. For short, after decades of development and use ash reincorporated E R V S into standard 90 and the commercial market has largely consolidated on the total energy wheel design. So how do they work
