Greenzone Engineering focuses on designing HVAC systems for cannabis and controlled environment facilities, where controllability, first cost, energy efficiency, and code compliance are all critical. We design for the owner, with the owner, weighing options against cost, combining our experience with the rest of the Team's.

We believe good outcomes can be achieved with various system types, but there are various cost, maintenance, and controllability considerations for the facility and room sizes being design and other design parameters/constraints of the project. We will help you choose the right HVAC system and design it the right way to achieve the outcomes you are looking for. We sell design and consulting services only, and do not sell equipment. 

Greenzone Engineering is a brand name used for Engineering Services offered independently by Ian Atkins (as a sole proprietor) based in NY and Kenneth Loshelder (through KL2E, LLC) based in PA. Kenneth and Ian are both licensed professional engineers with more than 25 years combined experience in HVAC and more than 10 years in controlled environmental agriculture projects. We have worked together on numerous unique and challenging projects, including two side by side 1300-Ton chilled water/hot water heat recovery grow facilities in Illinois, and one of the world's first 4-tiered aeroponics facility in Quebec. Combined we currently hold professional engineering licenses in AR, CA, CO, IL, OH, MA, MI, MN, NJ, NY, PA, TX, and WA.
