ASHRAE Society partners with the job board service Bird Dog to promote employment opportunities for the ASHRAE community. This effort is called ASHRAE Jobs. The link to ASHRAE Jobs ( can be found on the ASHRAE home page.

Since ASHRAE migrated ASHRAE Jobs to reside in the BirdDog applicant tracking system (ATS), ASHRAEJobs is now a one-stop location where your employers can search for certain skill sets and demographics that they are “always looking for” and build a talent community.

2014 Technology Awards – Apply now!

Every year ASHRAE asks its members to submit projects for the annual Technology Awards. These awards recognize both your and your client’s dedication to energy efficient, green design. Both the engineer of record and the client receive plaques and complimentary meals at the Spring awards program. This year we are asking the award winners to present their own projects at the awards program so their efforts can rightfully be recognized.

The submission deadline is February 28th, 2014. If you have any projects you think may qualify, just follow the instructions on the simple 2 page form and send it to Chad Adler, CTTC Chairman, at moc.icjnull@relda.b.dahc

Noise Controls for Rooftop Units and Noise Barriers for HVAC Equipment  -  John Paulauskis  -  JPAcoustics There are generally two types of rooftop units in HVAC systems, one that contains only fans and cooling/heating coils for supply and return/exhaust airflow, and a second type that includes compressors for DX coils in addition to the fans.  The “indoor” noise control methods for these two rooftop systems is different and requires an understanding of the noise sources and paths to occupied spaces below the rooftop units.  This presentation will provide recommendations for the most effective rooftop unit noise controls.   “Outdoor” noise from HVAC equipment located on rooftops and on grade can be attenuated by construction of noise barriers around the equipment.  The amount of noise reduction is dependent on the type of noise source, barrier construction details, location and height of the barrier, and the reflective surfaces around the equipment.  The effects of these parameters on the amount of barrier noise reduction will be presented.
