What's New with RED

ASHRAE 62.2-2013 and 62.2-2016 Online - Free

ASHRAE provides free, read-only, copies of some of their most popular standards online. 62.2-2013 and 62.2-2016 are two of these standards. Because you cannot get to them by clicking on a single link, RED has provided a short video to help you navigate to these documents on the ASHRAE website. The video will make it easy for you to complete the two- or three-step process to get to these readable - and searchable - standards. 

You will not be able to print or save these documents, but now that you know you can view them at any time, you don't need to. 

Check out the other video tutorials at the RED YouTube Channel.

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 5th time starting May 8th through June 18th, 2017. 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 use 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.
