See a VIDEO recording: HERE

SLIDES : The Past and Future of Ventilating Dwellings – ASHRAE 622-2013

Learn  how to better use the new ASHRAE 62.2-2013 Standard, Ventilation and Acceptable indoor Air Quality in Low-Rise Residential Buildings. There is a focus on existing dwellings and coverage of the details of the ventilation standard that will soon be adopted by BPl. The steps of sizing ventilation, both local and whole-building, are addressed in detail using the free web app by Residential Energy Dynamics (REDCALC).

The BPI Building Airflow Standard (based on ASHRAE 62-1989) and ASHRAE 62.2-2010 is addressed, giving historical context for the latest ASHRAE Standard 62.2-2013. The 3 versions are compared, however, the major focus is on 62.2-2013.

Those who will benefit: building performance and HVAC contractors, low-income weatherization analysts, code enforcement officers, or anyone interested in learning more about 62.2-2013.

National building codes, standards and programs are requiring the design, installation, testing, and documentation of ventilation systems. Participants in this course will come away with a better understanding of the science behind and mechanical ventilation technologies. Topics will include using the latest ASHRAE 62.2 Standard for sizing the systems for the right airflow for whole house and local ventilation, use of the infiltration credit, selecting the system, differences between ERVs and HRVs, use of controls, and installed system testing and documentation.

Where To Find Talent For Todays Skilled Trades

~ Liz Crawley, August 23, 2013

Graduates in Cap and Gown

In my career history, I have assisted skilled workers find temp-to-hire jobs, advised young adults on how to pursue employment, and most recently, aided college students in determining a direction for their academic major. In each of these roles, I have noticed a disappointing trend.

We keep pushing young adults to get an education and earn a degree, but we do not offer a great deal of help beyond that. “What should I do with this degree?” is a question, that often gets left unanswered.

While working for the university, I ran into several of my graduated students in restaraunts, retail shops, and fast food chains. These students are told there are no jobs and they are unsure if or how they are going to use their education.

At TruTech Tools, our own Bill Spohn shares a concern with me, a concern that these young adults are not fully aware of the career opportunies and earning potential that exists in skilled trades.

Bill Spohn, PE & CEO/Co-Owner of TruTech Tools (TM), LTD is cited in BEC- The hidden talent pool for the skilled trades-1-1, a recent article from Business and Education Connected (BE Connected). In this article, Bill Spohn expresses his concern that too few students are interested in pursuing careers in the trades sector.

Rather than ask why the problem exists, BE Connected proposes a solution, but I won’t give away the ending. Check out this article and please consider how you can do your part. BEC- The hidden talent pool for the skilled trades-1-1
