Inherent inefficiencies

A system designed to be energy efficient can be totally undermined if the whole system has to be operated to meet a small demand. For example, in small-scale buildings, it is not unusual to find an entire heating plant being run in summer to supply hot tap water. Unreasonable overcapacity is another problem. An elaborate and expensive chiller may be installed to meet the cooling demand of a few days in the year or to supply cool air to a small number of prestigious rooms. The scale of such inefficiencies may go unnoticed because of the absence of proper monitoring systems. System efficiency can drop dramatically without the management being aware of the problem. Often a catastrophic failure is the first indication that something is wrong.

Sophisticated controls and electronic management systems combined with zonal submetering will ensure that faults are pinpointed and system inefficiencies identified. The relatively small capital costs involved in such equipment will quickly be paid back. The operation of such systems must be supplemented by adequate supervisory and analytical input from knowledgeable staff.

Do we really want the one thing that gives us its resources unconditionally to suffer even more than it is suffering now? Nature, is a part of our being from the earliest human days. We respect Nature and it gives us its bounty, but in the recent past greedy money hungry corporations have made us all so destructive, so wasteful.
