Energy planning & building performance

• ASHRAE Level I, II & III Energy Audits

  Understand where a facility is losing value, with audits at the depth your decision requires.

• Battery Storage & Load-Management Advisory

  Size storage around a defined job, starting from facility loads and tariffs rather than a capacity chosen in isolation.

• Building Systems Commissioning & Functional Verification

  Verify that a facility's systems work together as intended, with deficiencies documented and follow-through coordinated.

• Commercial Air-Leakage Testing

  Whole-building air-leakage testing by Commercial Envelope Testing Co., a wholly owned Green Summit company, planned as part of closeout.

• Distributed Energy Consulting

  Decide on the energy investment before choosing equipment, connecting loads with costs, tariffs, incentives and verification.

• Energy Modeling

  Compare design and retrofit choices for housing, community and commercial buildings before committing to them.

• ENERGY STAR Portfolio Manager Benchmarking & Portfolio Analysis

  A repeatable view of which of the Nation's buildings need attention, and why.

• EV Charging & Electrification Planning

  Plan charging and other new electrical loads before equipment is selected, connecting demand, site capacity and operations.

• Manual D Duct Design

  Connect airflow requirements, equipment performance and available space with the duct system the crew will install.

• Manual J Load Calculations

  Start Tribal housing HVAC design from the calculated load, not a rule of thumb.

• Manual S Equipment Selection

  Select residential HVAC equipment for the conditions it will actually serve, matched to the calculated loads.

• Measurement & Verification

  Know what an improvement changed and why, with a credible baseline, the right data and a documented method.

• Microgrid & Resilience Planning

  Define which community services must keep running before choosing how to power them.

• Solar & Battery Feasibility

  Evaluate solar and battery storage against facility demand, site conditions, project economics and the Nation's operating priorities.

• Solar Inspections & Performance Verification

  Look beyond the production total: inspections, commissioning support and performance review tailored to the installed system.

• Strategic Consulting

  Make the next facilities decision with building performance, compliance, incentives and capital priorities in view together.

• Thermal Storage & Grid-Interactive Buildings

  Evaluate when energy is needed, not only how much; advisory and modeling approaches now in development.
