Key Considerations When Planning a New Cold Storage Facility
Planning a new cold storage facility is one of the more complex projects a food producer, distributor, or agricultural operation can take on. Unlike a standard warehouse, cold storage has to do something very specific—maintain precise temperatures reliably while product moves in and out. Get it right and you’ve got an asset that protects your product, controls your energy costs, and supports your operation for decades. Get it wrong and you’re dealing with temperature inconsistency, skyrocketing utility bills, and costly retrofits.
After years of designing, installing, and servicing commercial refrigeration systems across Washington, Oregon, and Idaho, the team at Central Washington Refrigeration has seen what works and what doesn’t. Let’s take a closer look at the considerations that matter most when you’re starting from scratch.
Know the Product You’re Storing
This sounds obvious, but it’s where a surprising number of projects go sideways. The refrigeration system, insulation package, and building layout all flow from one foundational question: what are you storing and what does it need?
A facility storing fresh produce has very different temperature and humidity requirements than one handling frozen seafood or pharmaceutical products. Multi-commodity operations may need distinct temperature zones within the same building—say, a freezer section at -10°F alongside a cooler section at 34°F. Each zone has its own insulation, refrigeration, and airflow requirements, and they all have to coexist in a building that’s thermally efficient and operationally practical.
Define your product mix, your target temperatures, and your anticipated throughput before anything else. Everything downstream (refrigeration system sizing, panel specifications, door placement) depends on getting this right.
Consider Your Building Envelope
Refrigeration accounts for a significant portion of a cold storage facility’s total energy consumption, making it the largest single operating cost for many. The quality of your building envelope (the walls, roof, floor, and doors) is the main predictor of how hard your refrigeration system has to work.
Insulated metal panels (IMPs) are the industry standard because they offer excellent thermal performance and structural integrity in a single prefabricated component. For freezer applications, you’ll also need insulated flooring with under-floor heating or ventilation systems to prevent frost heave, which can buckle a concrete slab if it’s not addressed in the design phase.
Vapor barriers are another area where cutting corners costs you later. Moisture that finds its way into the insulation system degrades its performance over time and can cause structural issues that are expensive to remediate. Proper vapor barrier installation at walls, roof, and floor transitions is non-negotiable for a facility you expect to perform for 20 or 30 years.
Doors deserve more attention than they typically get in early planning conversations. Insulated dock doors, rapid roll-up doors, and air curtains all minimize the temperature exchange that happens every time a door opens. The right door configuration for your traffic patterns pays for itself in energy savings.
Select Your Refrigeration System
The refrigeration system is the heart of the facility, and choosing the right one involves more than matching BTU capacity to square footage. The refrigerant type, system configuration, and redundancy design all have long-term operational and regulatory implications.
In the Pacific Northwest, we work with a range of system types depending on facility size, product requirements, and operator preferences. Ammonia systems are our top choice, as they are highly efficient and cost-effective at scale. They do require specialized safety infrastructure and engineering, and operators must receive proper training for compliance. Other options to consider include CO2 systems and halocarbon systems, with the latter being ideal for smaller facilities.
Another thing we’d like to point out is the importance of planning for growth. A common planning mistake we see at CWR is that sizing the refrigeration system is determined by the current needs with no headroom to scale. Adding capacity to an existing refrigeration system after the fact is expensive and disruptive. If there’s any chance that your operation will grow in the next decade or so, it’s best to design for that capacity now.
Get Electrical Infrastructure Right From Day One
Cold storage facilities are significant electrical loads, and the power infrastructure needs to be designed accordingly from the start. Refrigeration compressors, evaporator fans, lighting, monitoring systems, and dock equipment all draw extensive power.
In Washington, where many cold storage facilities serve agricultural and food processing clients, we also see a growing need to account for EV charging for refrigerated transport equipment at the dock. Getting a utility assessment and confirming your service capacity early prevents surprises that can delay a project by months.
Choose a Robust Monitoring and Control System
Modern cold storage facilities run best with robust monitoring and control systems. At minimum, you want real-time temperature monitoring with alarm notification. Any qualified refrigeration contractor will tell you that catching a temperature deviation at 2 AM before product is lost is worth whatever the monitoring system costs.
Many Washington-based food operations also have food safety compliance requirements that mandate documented temperature logging. This makes a capable monitoring system a regulatory necessity instead of an added perk. Additionally, programmable logic controllers (PLCs) and automated defrost scheduling can also reduce energy consumption and extend equipment life.
Get the Planning Right—Before the First Panel Goes Up
A cold storage facility is a long-term investment, and the decisions made during planning have consequences that play out over the life of the building. The refrigeration system you specify, the insulation package you choose, the electrical infrastructure you put in place set the performance ceiling for everything that follows.
At Central Washington Refrigeration, we work with clients from the earliest planning stages through installation, commissioning, and ongoing service. Whether you’re breaking ground on a new facility in the Yakima Valley, expanding an existing operation in the Willamette Valley, or planning a new build in Southern Idaho, we bring the regional knowledge and technical depth to help you get it right the first time.
