Project Overview
A new 25,000 sq. ft. cannabis processing facility in Texas required an MEP design built around specialized processing operations rather than conventional commercial occupancy.
The facility required tightly controlled temperature and humidity, extraction and chemical exhaust, process utilities, and substantial electrical and plumbing infrastructure. At the same time, the architectural layout and process requirements were being refined during a compressed design schedule.
The engineering challenge was to bring these requirements together into a coordinated building system without overbuilding the infrastructure or compromising the facility's operational needs.
What began as a greenfield facility design became a coordination challenge involving environmental control, process equipment, utility loads, and specialized infrastructure.
The Challenge
Controlling the Processing Environment
The facility required precise temperature and humidity control, along with dedicated exhaust systems for extraction and chemical-processing areas.
The HVAC design therefore had to account for both environmental conditions and the requirements of specialized processing spaces.
Integrating Process Utilities
The MEP systems had to accommodate process equipment and utilities alongside conventional building services, including electrical power, natural gas, domestic water, and compressed air.
These systems had to be coordinated around the facility's operational requirements and equipment locations.
Getting the Infrastructure Right
The facility's equipment created significant electrical and utility loads.
Oversizing the infrastructure would add unnecessary capacity, while undersizing it could restrict operations. Electrical and utility requirements therefore had to be evaluated carefully before determining the appropriate system capacities.
Delivering on a Compressed Schedule
The complete MEP design had to be developed and coordinated on an accelerated schedule while architectural layouts and process requirements continued to be refined.
This required the different MEP systems, equipment requirements, and project inputs to progress together rather than sequentially.
The MEP Engineering Approach
Designing Around the Process
The HVAC design was developed around the facility's specific environmental requirements, with temperature and humidity control integrated with extraction and chemical exhaust systems.
Equipment locations were also optimized to keep ductwork and piping runs efficient while maintaining code-compliant clearances and routing.
Right-Sizing the Electrical Infrastructure
Detailed load calculations were used to determine the facility's actual electrical demand.
This allowed the service, generator capacity, and power distribution to be sized according to the project's requirements rather than relying on excessive capacity.
Simplifying Hot-Water Infrastructure
Instead of using multiple water heaters, the team consolidated hot-water generation into a centralized gas-fired tankless system with storage.
This provided the required capacity through a simpler arrangement
Keeping Gas Utilities Out of Critical Areas
Gas piping was routed outside critical processing areas, keeping the utility infrastructure accessible for servicing while reducing its presence within the processing environment.
Coordinating Process and Building Systems
The MEP design brought together HVAC, electrical, plumbing, natural gas, compressed air, lighting, and controls around the process requirements.
Equipment manufacturers and the client were also involved during coordination to align the building systems with the facility's operational requirements.
Project Outcomes
The success of the project depended on aligning specialized processing requirements with the building's MEP infrastructure within a highly compressed design schedule.
The resulting design addressed environmental control, process utilities, electrical demand, and specialized infrastructure without adding unnecessary capacity.
- Right-Sized Infrastructure: Detailed electrical load analysis helped optimize service, generator, and power distribution sizing based on the facility's actual requirements.
- Process-Specific HVAC: Temperature, humidity, extraction, and chemical exhaust requirements were incorporated into the HVAC design to support the facility's processing operations.
- Simplified Hot-Water System: A centralized gas-fired tankless system with storage replaced the need for multiple water heaters, simplifying the hot-water infrastructure.
- Accessible Utility Routing: Gas piping was kept outside critical processing areas, allowing the infrastructure to remain accessible for servicing while reducing its presence within the processing environment.
- Accelerated Delivery: The complete coordinated MEP design package was delivered within the 2.5-week schedule, including the required calculations and permit documentation.

Project Journey
Establishing the Design Basis: The MEP design was developed from the revised architectural backgrounds, equipment schedules, and process requirements.
Process & System Coordination: Client comments and equipment requirements were incorporated while HVAC, electrical, plumbing, and process utilities were coordinated across the facility. Load calculations, equipment sizing, and utility layouts were refined to avoid unnecessary infrastructure while maintaining the required operating conditions.
Permit Submission: The coordinated MEP package, including calculations, panel schedules, single-line diagrams, generator sizing, and COMcheck documentation, was completed and issued within the 2.5-week schedule.
Planning an MEP design for a specialized processing facility?
Specialized facilities require MEP systems built around their unique processes, equipment, and operating conditions. The goal is to make these systems work together without overbuilding the infrastructure.
Frequently Asked Questions
