Our Experience

National Design Build Services has a diverse background in providing HVAC, refrigeration, mechanical piping, and plumbing design. Since our founding in 2007 we have developed the best possible solutions for your project with a focus on operability, first cost, and energy efficiency. Our designs are environmentally conscientious and limit the operational cost impact to building owners. We have experience in the CEA market for both indoor vertical grow and greenhouses.


Leafy Greens Vertical Indoor Grow Farm

Confidential CEA Client

Baltimore, Maryland

Bethlehem, Pennsylvania

Our first project with this grower included mechanical design and controls for an indoor grow farm in the Baltimore area. The project included renovation of an existing industrial space. The HVAC project scope included direct expansion rooftop units with hot gas reheat and auxiliary gas furnaces. Automated storage and retrieval systems for conveying crops within the 11-layer multi-level grow system in five grow ranges impeded constructability and required in depth assessment and CFD modeling of the distribution ductwork. Following initial construction, we were tasked with providing increased cooling and dehumidification capacity for within the existing grow ranges for increased operational flexibility and redundancy. The second phase of this project is nearing completion and we are continuing our relationship with work on three more projects.

Organic Herbs Vertical Indoor Grow Farm

Confidential CEA Client

Anderson, South Carolina

San Antonio, Texas

Providing mechanical design and installation for two new greenfield organic herbs production facilities. Plumbing design services are also being provided. Construction is underway on this first project site and this pilot plant will be rolled out to multiple project locations across the United States. Indoor racking and distributed utilities in the Grow and Nursery spaces impede constructability. Detailed approaches to duct distribution were necessary to ensure everything would fit and temperature gradients were minimized.

Leafy Greens Vertical Indoor Grow Farm

Confidential CEA Client

Muncie, Indiana

Providing mechanical system scope and budget definition for indoor aeroponics lettuce facility. Once scope and budget have been finalized, the mechanical installation and controls will be provided. The project included renovation of an existing industrial space. The HVAC project scope includes a prefabricated central utility plant with central chillers, cooling towers, connections for emergency rental cooling equipment, and pumps sized for duty/standby operation. Desiccant dehumidification has been proposed to maintain the indoor grains of moisture to the target criteria while reducing connected cooling tonnage by more than 30%. Additional cost considerations are being further assessed for in-rack temperature control which provides distribution directly to each plant.
