176+ years of combined experience

We are a group of highly skilled specialists (five Ph.D. and 11 master's degree in building science) dedicated to promoting energy efficiency in the building industry.

state-of-the-art tools

To achieve the best results, we use eQUEST, THERM, WUFI PASSIVE, WUFI PRO, ENERGY+, and the LCCA Tools. However, we enhance each model further by writing our own codes and scripts.

$35-45 per hour rate and no change orders

With us, you can predict your budget precisely, as we avoid change orders. Yes, we'll revise unlimited times until model reaches it's highest performance.

Trust us to handle all your energy modeling needs, ensuring compliance and optimizing efficiency for a greener future.

We mastered the understanding of energy modeling through designing 1,000+ projects. We're using  Energy Model Simulation Guidelines for typical assumptions for accurate normative compliance and we're constantly having feedbacks from the site to validate constructibility,  cost effectiveness, energy performance, durability


Energy modeling is a pre-construction, whole-building assessment of energy efficiency. We believe Energy Modeling is crucial for implementing the appropriate cost-saving energy conservation measures within a project, helping reduce budget costs. 


Energy modeling during the early stages of design helps to examine a variety of design variables and alternative approaches that would otherwise have gone unnoticed. As soon as preliminary plans for your project are completed, we may begin energy modeling. That is, you can contact us as soon as the fundamental floor plans, dimensions, elevations, and doors and windows have been designed.

Profits of hundreds of thousands of dollars can be gained by using Energy Modeling to choose the most cost-effective and high-performance component packages. We help Developers, Architects, Builders, MEP Engineers, and Sustainability Consultants. Architects and engineers can pick the best position of the building for the sun to save energy on cooling. They can evaluate whether or not using a highly reflective window is a waste of money when a moderately reflective window would suffice. The owner can comprehend the difference between installing a 20,000-watt or 50,000-watt solar energy system, calculate how long it will take to pay for it, and decide which system is ideal. Energy models assist owners and designers in determining the appropriate color for the roof–if spray foam or fiberglass insulation is preferable–and whether additional insulation might reduce the cooling capacity required for air conditioning, resulting in reduced equipment costs.

Developers may Invest with confidence while cutting construction costs to fulfill energy standards and tenant demands.

To summarize, you simply gain profit by lowering construction costs or investment, while also lowering carbon emissions.


The services offered by Archenergy are aimed at making energy modeling affordable for all types of buildings. Energy simulation, often known as modeling, is one of the most powerful building design techniques ever developed. It is utilized to comply with energy codes, earn LEED points, and report tax credits, but it is most effective when applied strategically to improve building performanceThis is achieved by modeling all building components and conditions to determine where the greatest energy savings may be found. The model examines the performance of the "whole-building."
