Take the uncertainty out of planning energy-saving projects with an energy study.

An energy study can show which energy conservation measures will work best for your facility. They evaluate the cost effectiveness of energy efficient improvements in existing facilities and new construction. 

Present your plan to Hawaii Energy while your project is still in the planning stage to:

• Determine if funding can be made available for your project
• Get recommendations to improve your energy efficiency
• Estimate your project costs
• Approximate the impacts these improvements will have on your energy bill
• Receive information on other possible improvements that qualify for Hawaii Energy rebates

A qualified engineer or consultant can examine energy efficient alternatives and prepare an Energy Study Report.

Existing Facilities Study

Hawaii Energy reimburses a portion of the existing facility's energy study costs up to $15,000. Pre-approval is required. Payment will be made to the customer upon completion and acceptance of the study.

New Construction Study

Design assistance funds for a consulting engineer to evaluate options for new facilities that will exceed Hawaii’s Model Energy Code. Funding is determined on a case-by-case basis. Pre-approval is required. Payment will be made to the consultant upon completion and acceptance of the study by Hawaii Energy. 

How to apply for Energy Study rebates 

1. Check the energy studies application.
2. Attach a proposal describing the concept and outlining the energy study that includes estimated costs and project timeline.
3. Attach any layouts, drawings, technical details or vendor literature with your application.
4. A qualified consultant/energy auditor must conduct the study. Submit a brief summary of the consultant’s qualification. In some cases, a professional engineer may be required to provide verification of the analysis.

Pre-approval is required. Energy Study funding is based on availability of funds. Projects are judged on a case-by-case basis.

The Energy Study Report

Upon approval of the energy study funding, a completed Energy Study Report must be presented. It should include the information below:

1. Executive Summary
   1. Energy Conservation Measures (ECMs) Proposed
   2. Summary of Baseline and Enhanced Case Assumptions
   3. Actionable Recommendations in "Loading Order."
2. Technical Information and Analysis
   1. Energy Consumption Analysis
      1. Two years of billing data (weatherized and compared to some pertinent operating metric)
3. Description of the Project
4. Proposed Energy Convervation Measures (ECM)
   1. Descriptive name
   2. Schematic system drawing
   3. Current peak demand (kW), energy usage (kWh), effective full load run hours

   9. Simple payback
5. Base Case Information
   1. Short term/spot baseline thermal, fluid and electrical measurements for major equipment to be changed with ECMs
   2. Permanent metering data (this metering will qualify for additional cost assistance)
   3. Sizing/performance reviews (pump curves, cooling bin data, etc.)
6. Enhanced Case Information
   1. How will performance be measured in the future
