This project involved a design of a new 3-story state of the art Police Headquarters building for the Orlando Police Department. This project was performed with a design/build contract as a LEED Silver Facility. RTM was responsible for full Mechanical, Electrical and Plumbing, Fire Protection Engineering Design associated with the project. Along with the design phase (completed in June 2015), RTM will assist in the construction administration phase for the respective disciplines.
The mechanical systems for this project included a complete VRF (Variable Refrigerant Flow) system with above ceiling fan coils and exterior ground mounted central condensing units. Rooftop DOAS (Dedicated Outside Air) systems which use Energy Recovery Technology provide conditioned outside air to all VRF fan coils. The Energy Recovery portion of the system exchanges energy from pre-cooled exhaust air from restrooms and other areas to the humid outside air. All systems were designed as variable speed controlling the amount of outside air delivered to the building based on occupancy/ carbon dioxide levels. The plumbing systems
include water conservation fixtures throughout the building. Rain water collected from the roof is connected directly into the local retention ponds designed with fountain features. The original electrical design included natural gas powered Micro Turbines which produce electricity on site while capturing waste heat to heat building domestic water. The design was performed as a “second utility service” which was required for the critical facility and since the bringing a second power circuit to the site was not feasible. UPS systems were utilized for emergency lighting along with data center/ computer power outlets.
During the latter part of the design, the power utility company had finally confirmed a way they could bring utility power to the site at a feasible cost. With this information, RTM worked with the utility company to update the payback analysis on the project and determined the second utility circuit seemed to be the best method of “back-up” utility power with the new installation cost provided. RTM modified the design and resubmitted the project removing the Micro Turbine design.
