Shade Structures and Evaporation Reduction
A shade structure is usually chosen for comfort, but it has a real, if secondary, effect on evaporation that's worth knowing about. The Woodlands Township Covenants require Design Review Committee approval for pool and backyard construction in nearly every village, and that review covers fencing, setbacks, and drainage as well as the pool itself.
Less Direct Sun, Less Evaporation
Direct sun exposure and wind are the two biggest evaporation drivers; a shade sail, pergola, or cabana positioned over or near a pool reduces direct heat gain on the water surface, which modestly reduces evaporation and the associated heat and chemical loss compared with a fully exposed pool.
Not a Substitute for a Cover
The effect is real but smaller than a properly used pool cover, which blocks evaporation far more directly; shade structures are worth factoring into an energy-conscious design, but a cover is still the bigger lever for a heated pool specifically.
