Condensate is an inherent byproduct of building HVAC systems. Since condensate is formed from moisture in the air, it is relatively high-quality water. Therefore, it can be collected and used on-site with relatively little treatment. Using condensate conserves municipal water and lowers energy costs associated with the municipal collection, treatment, and distribution of water that would otherwise be consumed.
Collecting condensate from commercial building heating, ventilation, and air-conditioning (HVAC) systems is relatively simple. Using condensate for on-site applications offers a potentially quick return on investment, especially in hot and humid climates. To help increase the implementation of condensate use, this manual was created as a guide for building managers, architects, engineers, and facility personnel to facilitate the comprehensive evaluation, design, and implementation of a condensate collection and use system for commercial buildings in San Antonio.
