Please Use Our New Website!


In early November of this year, we will shut down this website. For those of you using the RED Calc Free tools on this site, please start using our new website. You will find the tools are the same and the website is prettier! Thank you.

BIG News from RED

New Website Launched!

As of early October, the folks at RED launched our new website! Please check it out when you have the opportunity; we think you will like it. 

For those of you using RED Calc Free, all the Free tools are on the new website for your use. Within the next few months, we will take www.ResidentialEnergyDynamics.com (where you are now) off line, so you will eventually have to start using the new site. You can find the RED Calc Free tools here. A slide-out menus for the tools and user guides are on the left of each page. We will continue to support RED Calc Free.

RED Calc Pro Now Available!

We have been working long hours to bring RED Calc Pro to your computer, tablet, and smartphone. As of early October, 2019 it is ready for you to look over and purchase. The RED Calc Pro web application is only available if you subscribe on a monthly or yearly basis, but each subscription includes a two-week trial period (your credit card will not be changed for two weeks). You can learn about all the enhanced features by looking over the RED Calc Pro Manual, which is on the new website.

The pricing for RED Calc Pro subscriptions, available for individuals and teams, is on the new www.redcalc.com website.

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 the AirCycler app a try:  

AirCycler Annual Ventilation Cost Calculator

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.



RED and HeatSpring Offer Courses

Rick Karg of RED is presenting online courses through HeatSpring. Currently, two courses are available. 

ASHRAE 62.2 Ventilation for Single-Family Dwellings will be offered for the 11th time starting September 16 through October 27, 2019. Students have access to Rick for six weeks and access to the course materials for 12 months. 

Zone Pressure Diagnostics: Precise Leak Detection and Measurement in Buildings is offered at any time, without direct access to Rick.

Both courses feature RED Calc Free tools.
