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.

What's Creeping Around in Your Data Center? discusses the growing problem of damage to data-center computer systems and associated components such as telecommunications and storage systems caused by the corrosive effects of gaseous contaminants due to RoHS compliance and describes requirements of a successful corrosion protection program.

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.

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.

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.

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.

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.

The University of Oregon’s Lewis Integrative Science Building could be the first LEED-NC v3 laboratory to be awarded LEED Platinum in Oregon and possibly the country. Energy recovery is one key to achieving a LEED Platinum rating. One energy recovery solution incorporated by the project’s mechanical engineers was using air-to-water heat pumps to capture heat from the campus steam tunnels. This article, printed in the third quarter 2011 newsletter of the Oregon Association of Professional Energy Managers (Oregon APEM), explains how they did it.

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