The purpose of CALGreen is to improve public health, safety, and general welfare. Through enhanced design and construction of buildings, we use concepts which reduce negative impacts. We promote these principles which have a positive environmental impact and encourage sustainable construction practices.

CALGreen Checklist

  • The checklist is used to guarantee that green building practices are used from the beginning of the planning stage until the day the homeowners move in.   

  • First your CALGreen Inspectors (Delta T Energy) contact the jurisdiction you will be building in so that we can obtain that area's CALGreen checklist.  Not all checklists are the same and its important to obtain the correct one to make sure that you are meeting any additional local requirements. 

  • We then need a full set of plans for your project. We thoroughly go over your plans in the plan review process and make sure that all of the CALGreen requirements are correctly and clearly labeled throughout. If something is missing we will note it in our detailed response along with instructions on how to get the design up to code. 

  • Once our review is done we will sign the initial signatures section on the checklist and you will be ready to submit for permit.


  • Owner's or Owner Representative's Project Requirements (OPR)

    • Review and discuss environmental and sustainability goals, energy efficiency goals, indoor environmental quality requirements, ventilation requirements, project documentation requirements to include facility functions and hours of operation/after hours operation, equipment and systems expectations, and building envelope performance expectations.

  • Basis of Design (BOD)

    • Written report documenting integration of building systems and the Owners Project Requirements (OPR). This document is to be updated throughout the construction phase as change orders may occur. The Basis of Design (BOD) is to include HVAC
      systems/controls, indoor lighting systems/controls, water heating systems/controls, and all building envelope components that are considered in the Owners Project Requirements.​

  • Design Phase Review

    •  Design meeting to discuss project scope with owner(s), architectural team, MEP team, and structural engineer. The intent of the meeting is to discuss coordination between the 3rd party CALGreen inspector/building commissioner.​

  • Commissioning Plan

    • Document how the project will be commissioned and shall be started during the design phase of the building project. The Commissioning Plan shall include general project information, commissioning goals, systems that are going to be commissioned, and plans to test systems/components.​

  • Mid Construction Phase​

    • Mechanical, electrical, plumbing system testing/review during the rough-in

    • Review and prepare for the documentation and training requirements that are due at the final inspection. These items are to include systems manual and systems operations training

  • Final Commissioning Inspection

    • Final review of mechanical, electrical, and plumbing system. Review will consist of the initial start up/testing, coordination with acceptance testers and HVAC air balancing.

    • Systems manual and owners operation manual to include instruction of basic operations, maintenance, and trouble shooting of equipment/appliances within the building

    • Systems operations training will include system/equipment overview, demonstration of operations (this will be completed w/ the subcontractor present on site)

    • Completed commissioning report for city inspector and for building owner

CALGreen Rough-in Inspection

  • Ensure that the project is meeting all CALGreen code requirements during the rough-in stage for light fixtures, insulation, windows, doors, construction waste management plan, finished materials such as paints, sealants, adhesives, and caulking.

CALGreen Final Inspection

  • Final inspection components to verify water fixtures, humidistat sensors, and final materials declaration page of VOC limits
