Pool Rooms
Pool Dehumidification Basics explains what to consider when designing a pool dehumidification system: maintaining optimum air and water temperatures for swimmer comfort; airflow; ductwork and grilles; minimum outside air requirements; heat recovery options; and saving energy with latent heat recovery.

Chloramine Basics. Chlorine often gets the blame for the "chlorine smell" in pool rooms, but in fact the culprit is chloramines. This paper is a primer on: chloramine formation, proper pool chemistry, and the best methods for containing chloramines.

Aquatic Center Success. This Webinar transcript answers audience questions regarding successful pool design and dehumidification.

This brief video explores three myths about pool rooms.



Energy Efficiency
Energy-efficient technology available today can increase our energy supply cheaply, cleanly, and easily while creating jobs, reducing our trade deficit, reducing greenhouse gases, and improving air quality.
Evaporative Cooling
Evaporative cooling has made summers more bearable for thousands of years and with 21st century technology provides effective, economical, environmentally friendly, and healthy cooling. Evaporative cooling works well alone or as a supplement to a chiller or DX system.

For more information: Why SEER Ratings Matter. The deadly Chicago heat wave of 1995 dramatically illustrates how just one SEER point can have a huge impact on the electricity supply.

Transpired Solar Collectors
The U.S. Department of Energy calls SolarWall transpired solar collectors "the most reliable, best performing, and lowest cost solar heating system for commercial and industrial buildings available on the market today." View a brief video that explains how SolarWall collectors work and how they provide one of solar's best ROI.

Hybrid Water Source Heat Pump Systems
Most large buildings such as office towers, hotels, condos, schools, and retirement facilities need simultaneous heating and cooling for much of the year. Hybrid water source heat pump systems are the most cost-effective method for heating and cooling at the same time and offer significant advantages over traditional water source heat pump systems.

Air-to-Water and Water-to-Water Heat Pumps
Heat Pump Water Heater Basics is a brief introduction to heat pump water heaters: how they work, applications, and installation considerations.

Heat Pump Water Heaters: Design Details describes how single-stage and two-stage heat pump water heaters work, their capacity and efficiency, applications, designing systems, and financial comparisons.

Design Considerations for Commercial Air-to-Water Heat Pumps provides schematics for designing commercial air-to-water heat pumps in two-pipe and four-pipe systems.

This brief video explains how heat pump water heaters turn waste heat or ambient air into hot water and air conditioning.
