Smart Strategies for Converting Buildings or Cultivation Systems

A greenhouse or indoor farm is more machine than building: Once turned on, it constantly cycles to balance climate to targeted setpoints. In some cases, this makes retrofits more challenging than building from the ground up, especially if being done while the “machine is still running” in order to maintain income. Gain confidence in your project design and execution, whether it be retrofitting new equipment into an existing grow operation, or a more substantial retrofit of a vacant building into an agricultural facility. The workshop audience will learn how to monitor energy and water use and make informed decisions about the need for new cultivation systems, be it lighting, HVAC, benching, greenhouse covering, irrigation or water circularity. Expert panelists will also discuss energy upgrades and retrofitting to renewable energy. For full building retrofits, learn the unique load requirements, building envelope, utility access and contamination issues before the design begins rather than after construction is under way. Participants will gain an understanding of when outside specialists will be required for their project,  and what incentive programs exist to offset a portion of the costs.

Topical areas include:

  • Retrofitting existing buildings to CEA

  • Retrofitting  existing CEA facilities with more efficient systems

  • Measuring water usage

  • Energy Monitoring Tool Lending Programs

  • Building envelopes and MEP considerations

  • Considerations for DIY vs outside contracting 

  • Impact of new cultivation systems on existing systems

  • Retrofitting on-site renewable energy 


Learning Objectives:

  • Understand the scope and resources for the two types of retrofit

  • Learn how to assess the MEP and building structure for retrofit

  • Understand the impact of retrofitting a cultivation system upon other systems

  • Better plan and manage operations during a retrofit project


Target audience:

  • Cultivators

  • Operations & Facility Staff

  • Design & Construction Partners

  • Property Owners

  • Utility & Government Representatives
