The ASHRAE® new design guide, “Guide for Resilient Energy Systems Design in Hot and Humid Climates”, was developed USACE’s Construction Engineering Research Laboratory (CERL). Both the GSA Green Proving Grounds and U.S. Department of Energy’s High Impact Technology (HIT) Programs selected design methods and technology from the design guide. U.S. Navy implemented these best practices at Naval Support Activity (NSA) Orlando to pretreat the outside air using dehumidification prior to the cooling stage. This process is known as “outdoor air pretreatment device to decouple the latent and sensible loads”. 

Andy Lynch, Academy Energy Group & Jim Meacham, PE, Altaire Systems review the Design Guide, discuss GSA GPG and DoE HIT Programs, and share technology implementation at NSA Orlando of innovation and best practices. 

LEARNING OBJECTIVES 

• Learn about new ASHRAE® & how it is referenced by Unified Facility Criteria (UFC).

• Learn about how the Government supports the development of innovation to promote health, resilient, sustainable, and energy efficient buildings through GSA and Department of Energy. 

• Learn about the benefits to buildings, operations, energy efficiency and people by following best practices from ASHRAE® design guide for the pretreatment of outside air. 

• How to achieve the balance between what seems like conflicting goals of ASHRAE 90.1 (Energy) and ASHRAE 62.1 (Ventilation).
