Best Building Efficiency Systems Tool

Faster. Better. Easier. Still Free.

Download the BEST way to compare HVAC system options for free!

The Building Efficiency System Tool® (BEST) solves the industry challenge of accurately comparing different styles of HVAC systems early in the design process. BEST brings EER, IEER, SEER, and COP data together to compare the performance, life cycles, and costs for any type of HVAC system – apples to apples!

Developed by the industry, for the industry.
BEST was created by a diverse group of commercial manufacturers from the United States, Mexico, and Canada to help prospective buyers, consulting engineers, and design/build professionals analyze real-world HVAC options to pinpoint the best system that meets budgetary and performance requirements.

New Features.
The latest upgrade features the new Simple Building Types Wizard. Just pick from 11 different building types and see how the four most common HVAC systems stack up based on your location and building size. It doesn’t get any faster than this! We have also updated all of the fuel cost data and climatological data from across the US, Canada and Mexico. Plus we have added all new video training tools to help you get started on becoming an advanced user.

Simple to use.
Just enter the square footage of the building, number of stories, and the nearest city for local weather data. Choose from more than 30 pre-loaded HVAC system types or customize for your particular building needs, then compare results. BEST features more than 100 default input settings, including system cost per square foot, that are all adjustable to model any building in any location. BEST quickly outputs estimated installation cost, replacement cost, maintenance cost, monthly energy cost, electrical and fossil fuel consumption costs, total life cycle cost, cumulative life cycle cost by year, system payback time, pump and fan HP, system coefficient of performance (COP), and more.

Choose wisely with BEER.
The BEST tool features the innovative Building Energy Efficiency Ratio (BEER) which calculates a system efficiency rating as applied under actual building operating conditions versus a lab. It builds off the numerous AHRI equipment rating and testing standards so now all types of equipment can be fairly evaluated against each other. BEST and BEER provides the key data to help make an informed system choice, even very early in the design process.

A game changer.
BEST gives you all the impartial answers you need and it’s very easy to use. Read all about it, watch the videos, and download BEST for free. No ads, no gimmicks, no upsell. Just free.
