Energy Modeller / Building Energy Analyst

RemoteFull-TimeU.S. business hours

Hands-on experience on U.S. commercial building projects is required for this role, not preferred. ASHRAE 90.1 Appendix G and 179D are specific to the United States, and a modeller who has only worked to other national codes cannot pick this up on the job at the pace the work needs. If your energy modelling has been entirely on projects outside the U.S., this role is likely not a fit. It is also simulation work specifically. You would build whole-building models in eQuest, DesignBuilder and EPFace, run validation and energy balance checks, verify unmet load hours, and produce the documentation that supports a 179D claim. It is not HVAC design and it is not field energy auditing. If your background is designing HVAC systems, or walking buildings and reading meters, that is a different job to this one. What is needed is someone who can take architectural, HVAC and lighting drawings and turn them into a model that is right, and who can tell when a model is wrong.

Build and validate whole-building energy models for U.S. commercial projects - ASHRAE 90.1 Appendix G baseline and proposed cases in eQuest and DesignBuilder, energy cost savings analysis, and 179D compliance documentation.

About this role

This is whole-building energy simulation for U.S. commercial projects. You would develop and review baseline and proposed case energy models to ASHRAE 90.1 Appendix G, model a wide range of HVAC systems across those buildings - VAV with reheat, chilled water plants, air-cooled chillers, packaged rooftop units and heat pump systems - and run the energy cost savings analyses that compare proposed performance against baseline. A large part of the output is documentation supporting 179D tax incentive and deduction requirements, which has to hold up to review. Day to day you would translate architectural, HVAC and lighting drawings into simulation-ready models using eQuest, DesignBuilder, EPFace and Bluebeam Revu. Just as important is knowing when a model is wrong: running model validation and energy balance checks, verifying unmet load hours, identifying modelling issues and recommending the corrections, and holding consistent modelling standards across the whole project portfolio. You would coordinate with internal project teams to get accurate inputs and deliver on time. The codes here are U.S. codes. ASHRAE 90.1 and 179D are specific to the United States, so hands-on experience on U.S. commercial projects is genuinely required rather than preferred. This is a fully remote position for a candidate based in India, working U.S. business hours.

What you’ll do

  • Develop and review baseline and proposed case energy models to ASHRAE 90.1 Appendix G
  • Model HVAC systems including VAV with reheat, chilled water plants, air-cooled chillers, packaged rooftop units and heat pump systems
  • Analyse building envelope and lighting performance
  • Perform energy cost savings analyses comparing baseline and proposed performance
  • Prepare detailed documentation supporting 179D tax incentive and deduction requirements
  • Translate architectural, HVAC and lighting drawings into simulation-ready models
  • Run model validation and energy balance checks
  • Verify unmet load hours and resolve what causes them
  • Identify modelling issues and recommend corrections
  • Maintain consistent modelling standards across the project portfolio
  • Coordinate with internal project teams to secure accurate model inputs and deliver on time

What we’re looking for

  • 2+ years in building energy modelling or energy simulation
  • Hands-on experience on U.S. commercial building projects
  • ASHRAE 90.1 Appendix G methodology
  • 179D energy modelling and compliance analysis
  • Whole-building energy model development, baseline and proposed case
  • HVAC system modelling across VAV with reheat, chilled water plants, air-cooled chillers, packaged rooftop units and heat pump systems
  • Building envelope and lighting performance analysis
  • Energy cost savings analysis
  • Model validation, troubleshooting, energy balance checks and unmet load hour verification
  • eQuest
  • DesignBuilder
  • EPFace
  • Bluebeam Revu
  • Able to interpret architectural, HVAC and lighting drawings
  • Strong written and verbal English communication

Nice to have

  • QA and QC review leadership
  • Mentoring team members
  • Improving and standardising modelling workflows
  • HVAC optimisation and energy-efficiency studies
  • Energy-efficiency optimisation experience across diverse building types such as hospitality, educational and commercial
