Commercial Services

  • We execute industry-standard audits following ASHRAE Level 1, Level 2 and Level 3 guidelines, or customize audits to your needs.  We like to think that our fully illustrated reports are among the best in the industry. We are experts in detailed electrical load inventories, and in finding ways to reduce your energy and demand charges. We perform detailed financial analysis for EEMs using metrics of ROI, NPV, or others of your choice. Our specialties include:

    1. HVAC operating cost optimization
    2. Lighting consulting 
    3. Net-zero energy calculations

  • We have Mechanical Engineer (PE) on staff, so we are well positioned to take care of your Title 24, Title 20, CALGreen, or other compliance concerns.

    We use EnergyPlus, OpenStudio, and CBECC Software to help you right-size mechanical systems, predict operating cost, process incentives, and compare design alternatives.

    Our expertise includes advising you about which system components and energy sources to use. This goes well beyond HVAC - envelope, lighting and water heating always need careful consideration as well.

  • We have a Certified Building Commissioning Professional on staff, who is also a P.E. Mechanical Engineer. We will gladly do Title 24 commissioning for your project. Our experience includes large and complex buildings such as local government offices and buildings for medical uses.  

    NegaWatt also meets the requirements to act as a Commissioning Agent for Enhanced Commissioning of LEED (which has to be done by an outside party, not affiliated with the GC). 

  • Thinking of taking your building to the next level? We will gladly take your project all the way to certification, or work on just the tricky energy prerequisites and credits, including enhanced commissioning. NegaWatt is a member of the USGBC. 


  • Need to establish the Energy Star rating of your building? AB1103 questions? We'll be happy to help with data collection and determining your building's score.

    If your score is in the top quartile, you qualify for the Energy Star Plaque - a great way to showcase your commitment to energy efficiency, and to attract long-term tenants.

  • Our monitoring services can be set up to be utility-grade, with highly accurate meters, tamperproof enclosures, and encrypted communications. The next logical step? We can do billing and reporting off of the data as well.

    Micro-utilities welcome! We'll take care of your overhead so you can focus on your core business.

  • Consider our experience with instrumented measurement and verification, and our president's Software Engineering background: this unique skillset allows to provide data analytics for your energy project with unprecedented efficiency and accuracy.  If your projects include networking or database components, for example setting up remote data logger access, or implementing a data warehouse, we'll take care of that, too.
