An energy efficient raised perimeter overflow pool, powered by a single variable drive pump.
The most energy efficient design involves replicating a thermos. For instance, a fully insulated covered pool that is removed from all outside environmental influences will approach an energy efficient nirvana. However in the real world clients use their pools, water features, fire features and living environments. By nature these simple activities increase energy costs and lower the efficiency levels of any project.
The best time to incorporate energy efficiency into a project is at the planning stage. Before a shovel hits the ground a well-designed and thought out project will provide enormous long-term energy and cost savings. Some of these items can be retrofitted to an existing project.

The pool or spa should be located in an area of maximum sun exposure. Consider sheltering the project from cooling winds by using screens, raised walls, glass fences or soft landscaping. earth they run through travelling from the pool heater to the pool shell.

Deep pools contain more water that is both difficult and more costly to heat. Consider building a shallow or sport pool.

Another consideration is to place the return jets into the deepest part of the pool. The hot filtered water will then evenly distribute throughout the pool. This even water distribution will avoid thermoclines or cold water layers that can develop in poorly circulated pools.
Waterfalls and water features can be a welcome aesthetic addition to any project. Unfortunately they waste a tremendous amount of heat, water and energy in order to operate. Consider designing water features to be simplistic in nature or one that does not use heated pool water in its operation.
Underground bunkers or equipment vaults save large amounts of space and energy in new construction builds. Bunkers located directly beside the pool minimize plumbing runs, save heating costs and never freeze even in cold climates.
Pumping or circulating the pool's water can cost a small fortune. Old style pumps with small diameter plumbing running 24 hours a day can cost hundreds of dollars a month to operate. Consider installing a simple timer, automation or ideally a variable drive pump combined with large diameter plumbing. The cost and energy savings are staggering.
Automation allows users to program pump(s) to operate as required. Pumps can be programmed to operate during off peak, low cost hours. Large energy-consuming pumps used for high volume water features and spa jet pumps can be programmed to run for a limited time. Low energy LED pool lights and outdoor lighting can be programmed to operate for selected durations.
WATER LEVEL CONTROLS
Every water feature, pool or spa should be equipped with an automated water level controller. These simple devices are programmed to run for a limited time ensuring that a leaking body of water is not simply filled forever, wasting water. Surge tanks are normally constructed to handle the overflow water from vanishing edge or perimeter rim pools. In areas with water restrictions, surge tanks can be used to capture rainwater from house downspouts or sloped concrete pool decks. This "free" water can then be cleaned and filtered ready for use in residential pool or water features.

The addition of pool covers can save 70% of a pool owner's heating costs. Automated pool covers prevent the pools heated water from evaporating.
The majority of these energy-saving features need to be considered before the watershape is constructed. Some simple design elements will allow pool owners to enjoy the pool or spa at a reasonable cost, and help save energy resources.
