Economies in Equilibrium
Efficient systems require balance. Part of my job is to discover out-of-balance components before they compromise function and safety. I rail against the over-emphasis on appearance at the expense of durability because I know, sometime in the future, failures will occur.
Appearances do make a difference, especially when they express common architectural language with a unique voice.
Lowes and Lead Paint
Contractors are tasked with identifying and controlling lead paint during renovations. This new approach is still a bit out of balance:

Pressure Balance
Pressure Regulating Valves (PRV) protect your water piping from excessive external pressures generated from the public water supply. Thermal expansion devices protect piping from internal pressures. You need both.
Negative Returns
Balanced airflow in a forced air duct system is critical. If the area of return openings is insufficient pressure is balanced by drawing air from outside the conditioned space. This often leads to comfort and air quality deficiencies. A house without adequate return openings is pressure negative. It sucks.
