(a)

1. (1) Do not overlook water conservation as an opportunity to reduce or manage the building operating cost.
2. (2) When selecting water-cooled or liquid-ring seal equipment, consider the water usage rates.
3. (3) When designing or operating lawn irrigation systems, consult with the University of Arkansas Cooperative Extension Service to determine the maximum water rates for all vegetation.
4. (4) Evaluate the soil conditions with regards to absorption rates.
5. (5) Where possible, provide irrigation systems that calculate the evaporation transpiration rate based on local conditions.
6. (6) It is more effective to have multiple watering cycles to allow ample time for the water to absorb into the soil than to have longer cycles which results in excessive run-off.

7. (7)

   1. (A) Be cautious not to overwater, especially where large trees are concerned.
   2. (B) The damage caused by the loss of an old growth tree due to overwatering can be many times the cost of proper watering in that area.

8. (8)

   1. (A) Where possible, use plumbing fixtures with infrared sensors to activate the flow of water.
   2. (B) This not only saves water but also is more sanitary and reduces the transmission of bacteria from hand contact with the fixture.

(b)

1. (1) Departments and designers should endeavor to specify new equipment and fixtures to be Energy Star® compliant.
2. (2) Energy Star® equipment has been tested and certified to be low energy consuming during normal operation.
3. (3) In addition, many Energy Star® products such as computers have built-in power reduction modes that further reduce energy consumption during nonuse or standby periods.
4. (4) Building managers should encourage occupants to not defeat or disable these energy reduction features.
5. (5) Equipment, like building systems, should be selected based on the best life cycle cost for each specific application.
