FAQs from Employers & Designers
During the job analysis study, we received some very good questions from P.E.s, HVAC designers and employers. Here are someexcerpts with responses.

Q. I wonder if this industry doesn’t already have enough certifications?  

The Certification Committee determined that while many P.E.s do HVAC design work, there are no certifications for the non-P.E. HVAC designer.  While we expect many P.E.s will apply for the CHD, the certification validates competency of the HVAC designer, working under the responsible charge of an engineer. 

Q. Is there need for this new certification?

In an “Industry Need” survey, ASHRAE Member respondents who work with HVAC designers wholeheartedly agreed (95%) that “the level of competence among HVAC designers varies greatly.” Respondents who influence the HVAC Designer hiring decision said the HVAC Designer certification would be “a worthwhile professional development goal” (82%) and “a tool to identify competent new hire prospects” (74%).

Q. Isn’t it actual experience in the industry that makes you competent, not passing a certification? 

Exactly. The purpose of certification is to validate competency. With its mix of recall, application and analysis questions, only a competent HVAC designer could pass the exam. The pass rate on ASHRAE’s other six certification exam ranges from 49% to 80%.  We expect employers will use the CHD as a professional development goal for their company’s HVAC designers and make it the must-have credential for new hires.

Q. How can an exam adequately validate a person’s real capability and aptitude?  Aren’t some folks just good multiple-choice exam takers?

With its mix of recall, application and analysis questions, only a competent HVAC designer with real-world experience will be able to pass the CHD exam.  The “wrong” answers on an exam are called “distractors,” because they have to be plausible enough for weaker examinees to select them, which is often the case. 

UPCOMING IMPORTANT DATES:
