NEO | Net Energy Optimizer Helps Building Owners, HVAC Contractors, and Energy Professionals Tackle Energy Modeling

The software solution can help show decision makers the value of upgrades to their buildings’ systems


To optimize energy modeling for buildings, since modeling is a valuable tool that is underused due to traditionally being time-consuming and complicated.


NEO leverages automation to make energy modeling easier, faster, and more accessible, regardless of building size or the contractor’s technical expertise. The NEO | Net Energy Optimizer provides an advanced technology solution that makes energy modeling more accessible, accurate, and affordable.

SOFTWARE SOLUTION: NEO automated modeling saves time and money by reducing the number of hours it takes perform an analysis.



Product Details:

NEO uses default inputs derived from industry standards (ASHRAE, COMNET, and RS Means) to inform and automate baseline models. NEO provides results in seconds, so its automated modeling saves time and money by reducing the number of hours it takes perform an analysis and makes the design and product selection process significantly more efficient.

NEO is a web-based energy modeling tool that utilizes the DOE-2 simulation engine and provides energy conservation measure rating analyses, energy audits for existing buildings, code compliance, and more. The energy modeling software streamlines whole building analyses of HVAC systems and energy conservation measures for commercial buildings with the versatility to support product comparisons, existing building energy audits, and new construction from early design through construction.

“With evolving construction technology, more stringent building codes, and limited project resources, the impact of design decisions continues to grow,” said Eric Flower, software account executive for Willdan. “NEO helps drive increased efficiency, reduces dependency on fossil fuels, and promotes new technologies by giving stakeholders performance-based answers to their complex product selection, building audit, or new construction design decisions.”

NEO graphically reports results, generates downloadable input/simulation files, and creates CSV and MS Word documents detailing key model inputs and outputs. NEO is web-based, touch friendly, and requires no software installation. Flower explained that NEO provides the actionable data needed to prove the energy, environmental, and financial value of a systems decision. This can help teams embrace new technologies that they may have initially dismissed due to an upfront cost.

“As the NEO user becomes a more educated consumer, supplier or consultant, a circular feedback loop influences: Designers to build more efficient buildings, operators to run them optimally, and equipment manufacturers to build more efficient systems to meet market demand,” said Flower.

“NEO has been very beneficial for the projects we’ve used it on. I’ve been able to perform early analyses and provide a professional looking report to clients, giving creditable information without a lot of upfront 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.”
