Gaylord National Harbor

The Gaylord National Hotel and Convention Center, the largest convention resort on the Eastern Seaboard, is located within the 300-acre National Harbor mixed-use water development.

The vision began with 100,000 square feet of retail and restaurants and grew to 2,500,000 square feet. This new facility will include a 2,000-room hotel, restaurants, bars, retail and entertainment venues; a 1.5-acre glass-enclosed atrium with 470,000 square feet of flexible convention, meeting, exhibition and pre-function space; a 50,000 sf ballroom featuring a theatrical stage, three additional ballrooms totaling 52,000 square feet, plus 2,000 parking spaces.

To optimize performance of the HVAC systems and minimize initial construction cost, WSP USA conducted a detailed Computational Fluid Dynamics (CFD) analysis to analyze the impact of solar heat gains and winter heat loss on the environmental conditions within the almost all-glass atrium. The analysis led to the design of a radiant heating/cooling floor and displacement ventilation.

A number of additional sustainable design features have been designed including the selection of the high-performance glass used in both the atrium and other venues. Active daylighting controls have been incorporated in the electrical system to turn off or dim the lighting system in response to natural daylight, saving both electrical and cooling energy. Other high-performance features include: use of high-efficiency electrical chillers, variable speed cooling towers and the use of cooling tower fans to enhance garage ventilation systems. The hotel systems incorporate heat recovery to reduce heating and cooling consumption.
