  • Review recommendations, chart a course of action and explore funding options

Energy audit: To identify improvements and estimate costs and savings

  • Receive a detailed list of energy upgrade options and recommendations

Design engineering & development: To design your project

 If you choose to proceed, New Ecology provides customized pre-development services to get your project designed, funded and ready for implementation. Services may include: mechanical engineering design, bid specifications, construction documents, work bidding, environmental testing and securing utility incentives.
