Why NEO?

Versatile and Highly Capable:

Quickly and easily simulate hundreds of custom energy conservation measures.

40 Plus Years of Experience:

We’ve empowered engineering teams to model 4,312 buildings modeled and save $266 million in energy costs.

Customizable & Efficient :

Determine which energy efficiency measures yield the best ROI for both new and existing buildings.


NEO is a powerful, easy-to-use online energy modeling tool that provides users the most accurate information available, when it’s needed most.

The NEO Difference

Its versatility allows engineers to perform HVAC life-cycle cost analyses, product comparisons, energy audits for existing buildings, and model new construction from early design through construction.

How NEO is Powerful in its Simplicity


Meets engineers unique energy modeling needs


Powerful and straightforward in its simplicity by providing energy optimization with a clear user interface


Real-time energy analyses – get results in seconds, not in hours or days.


Utilizes hundreds of industry standard data points. You can compare, contrast and make more informed decisions knowing you have relevant information for your project.

Accessible, Accurate & Affordable: NEO Explained

Save time and money by consolidating your workflow into one tool, giving you the data you need when you need it most.

Engineers are often faced with tight budgets, timelines, and technical barriers. That’s why NEO was developed – to combat those difficulties to make energy modeling more accessible, accurate & affordable.

Energy optimization in business


LEED BD+C New Construction – Miron Construction Regional Office

The project team utilized the NEO Net Energy Optimizer® energy analysis tool to establish the energy efficiency criteria for the proposed design using Option 1: Whole Building Energy Simulation under the LEED Energy and Atmosphere EAc2 Minimum Energy Performance credit. The project was awarded 16 Points under EAc2 and achieved LEED Silver certification.

"NEO’s sophistication analyzes the interdependent energy calculations, yet is simple enough to allow the LEED reviewers easy insight into the parameters and assumptions that build the model. We found it to be a cost effective and time-effective option.”

– Andrew Bennett, SystemWorks LLC

"Great software, cost effective modeling and ECM development. Also a terrific support team behind the product.”

– Jeffrey Myrdek, Director of Energy & Sustainability, CBRE

"I've been able to perform early analyses and provide a professional looking report to clients, providing creditable information without a lot of up front work. The efficiency of NEO has helped me remain profitable as it reduces the amount of work I have to do before pen hits paper.”

– Brian D. Howell, PE, CxA, Farris Engineering

"This was the first training I ever went to where I felt that I could use the tool the next day."

– Alec Phillips, TRC

"NEO has been an invaluable resource for our firm in early design, allowing our project teams to compare different mechanical systems and energy efficiency strategies in an iterative process. NEO has proven itself to be a great complement and gateway to the other modeling programs we use in later design phases, adding clear value to our design process. We have been very pleased with the software’s ease of use and incredible support team."."

– John Nichols, Director of Energy Analytics and Informed Design, Moseley Architects
