Free Building Science Calculation Tools for Energy Professionals

What's New with RED

RED Calc Pro Tools Development

We have been working long hours to bring RED Calc Pro to your computer, tablet, and smartphone. This new professional version of RED tools will include: 

  • Real-time collaboration with co-workers
  • Off-line operation
  • Mobile-friendly features, automatically adjusting to your screen size 
  • A separate, printer-friendly and customizable report 
  • Streamlined screen formatting
  • Improved error and warning messages
  • Ability to toggle math-on-the-fly
  • Ability to save job files to the cloud
  • User development of custom templates

The flow of RED Calc Pro will be centered on your created jobs, allowing you to display and save selected RED tools for a job and share these files with chosen co-workers, for example, the post-inspector and QC inspector. RED Calc Pro will look more like the Annual Ventilation Cost Estimator RED developed for Panasonic. We will continue to support RED Calc Free tools.

Cost to Operate Ventilation

RED worked with AirCycler and Panasonic to publish two estimating tools for determining the annual cost to operate ventilation systems (RED engineered and authored all the calculations). Each web application includes eight options, from exhaust-only to heat recovery ventilation. The low cost of operation might surprise you. Please give these apps a try:  

AirCycler Annual Ventilation Cost Calculator

Panasonic Annual Ventilation Cost Estimator

Because of the override options, these web applications will give you the annual ventilation cost you need for almost all available ventilation options. Each app includes a Background and Assumptions document link. As far as we know, there are no other apps available for these estimates.
