Greenhouse Climate Control System Installation

The Naval Research Laboratory (NRL) in Washington, DC is seeking a contractor to provide and install a complete greenhouse climate control system. This system must be capable of simulating a Southeast Asian tropical environment by precisely and automatically controlling temperature, humidity, air circulation, and solar radiation/light exposure. The contractor will be responsible for all labor, materials, equipment, software, installation, integration, commissioning, training, and documentation. The scope of work includes the removal of existing low-voltage control panels and wiring, and the installation of new components such as a relay contactor control panel, access point controller, space temperature/RH sensor, backup temperature sensor, and a weather station. The system must include real-time monitoring, data logging, automated control with manual override capabilities, and fault detection/alarm notifications. The contractor will also be responsible for installing and configuring the operating system and control software on a dedicated server provided by the end-user, and ensuring proper communication between control panels and the server via CAT6 cabling. The system must meet specific performance requirements for temperature (maintaining approximately 80°F), humidity (maintaining approximately 80% RH), air circulation, and ventilation. Shade operation will be based on solar radiation or light levels, and outdoor environmental data will be used for control decisions. The contractor must perform point-to-point verification, sensor calibration, and functional performance testing to ensure the system meets acceptance criteria, including temperature and humidity accuracy, correct operation of all components, and successful remote access functionality. A minimum one-year warranty covering all equipment and hardware is required.
