HPT Provides HVAC Solution for Grand Hyatt Tampa Bay

The Grand Hyatt Tampa Bay in Tampa Bay, Florida was looking for an HVAC solution that would cool and dehumidify its 226,700 sq ft hotel located in a region that is famous for its high humidity. With average regional temperatures that range upwards of 90°F in the summer the hotel needed to find a way to make its guests comfortable in even the hottest conditions. That is why the Hyatt implemented a solution from Heating Pipe Technology (HPT) a Berkshire Hathaway company.

With a humidity goal of 65°F inside the hotel’s living and working areas the building used a solution that involved a “wrap-around” passive energy recovering and dehumidification HVAC system. The Grand Hyatt’s new system works using energy redistribution. The new HVAC piping was designed to occupy a place on both sides of a cooling coil. The “warm side” of the HVAC system, where ambient air is taken in, and the “cold side,” where air often has to be reheated before use in living/working areas. The new approach balances the heat, redistributing it to the appropriate side of the cooling coil, thereby avoiding the cost of reheating the dehumidified air for use.

In practice, this means that some of the heat from the incoming ambient air is re-used to reheat the cold-side air, while incurring no additional energy costs. By distributing the heat around the HVAC cooling coil to where it is needed, HPT allows facilities to avoid substantial and wasteful energy expenditures.

According to the company, the HPT solution must be engineered and custom-designed for each installation in order to achieve proper balance. Since manufacturers HPT manufacturers have all their own components, the company must use in-house and consulting engineers to complete the system design.

The new HVAC design at the Grand Hyatt now includes HPT components and has shown dramatic efficiency gains. Currently, the hotel will save 464,000 kW hours each year amounting to an annual savings of $37,000. The new addition means that the hotel will also reduce its CO2  output by 320 metric tons.
