Water in the Air
Do pools raise humidity? Given that moisture content of the air is the result of evaporation, the vast majority from the ocean, is it possible that areas with high numbers of pools experience more humid conditions? If so, do pools ironically compromise the outdoor experience rather than offer comfort? Eric Herman tackles those questions, with an eye toward separating fact from “suburban” myth.   ...

The Humidity Factor
Indoor pools are wonderful as both design challenges and family recreation centers.  But as Paolo Benedetti discusses here, they'll stand the test of time only if you take care of moving the moisture they generate away from the indoor space -- no shortcuts allowed!  
Plastering When It’s Hot?
In several of the articles I've prepared for WaterShapes, the point has been made that it's not a great idea to apply plaster as the interior finish of a swimming pool (or any other watershape, for that matter) in spells of hot, dry weather - and I thought it was time to dig in a bit deeper and explain the reasoning behind that assertion. Basically, when a layer
Where the Bison Swim
The Arthur D. Kinney Natatorium was designed with a practical mission in mind:   From the outset, the facility was intended to provide long-term performance, outstanding aesthetics, ease of operation and minimal maintenance life cycles while enhancing the university's recruiting efforts and fostering individual and team achievement. In this case, however, the "individuals" aren't just star athletes pursuing records and titles.  Rather, the natatorium on Bucknell University's Lewisburg, Pa., campus is unique in the sense that the school chose not to segregate varsity athletes from general student/recreational users.  Indeed, the facility, part of the university's grand Kenneth G. Langone Athletics & Recreation Center, is designed to bring everyone
Inside Air
It seems so simple:  No matter whether it's a residential or commercial project, the design parameters for indoor swimming pools generally call for warm water (typically 82 degrees, or a bit less for a competition pool), air temperature two to four degrees warmer than the water, and a relative humidity in the enclosed space of between 55% and 60%. And it wasn't some committee of pool builders who came up with those figures:  The numbers are endorsed and published by the American Society of Heating, Refrigeration & Air-Conditioning Engineers (ASHRAE) and have been accepted as
