Targeting maximum LEED points especially in GCC countries require more common sense and deeper understanding of the effect. I also urge clients/developers to be open minded pertaining to their LEED vision. One good example is the rain water collection system. Most of the overwhelmed individuals I have worked with keep on insisting to collect the rain water for reuse specifically for flushing and irrigation. Inexperienced individuals do not realize that considering this in GCC countries is a waste of wealth, effort and energy considering the facts that lay before us. Plainly speaking, average rate of annual rainfall in the Middle East is very less. I do agree that sometimes rain intensity is higher as experienced somewhere in the previous years. But this is not a strong criterion.
By trying to harvest rain in the Middle East, one does not collect water actually. It turns into a scenario of collecting mud, dirt, contaminated water. This water then requires additional treatment for reuse, - simply meaning one needs to use adequate chemicals and systems to treat it; one requires to spend money for this treatment system; more water is essential just to backwash the filters; electricity is required to operate this pumps and trained manpower to maintain the tanks.
In short, there's no benefit for this idea but an endless and incessant burden. I do agree to the vision of LEED system and the benefit of this to people and environment. However, professionals must realise the appropriate implementation of this in the right place and at the right time
