IGCC Releases Training Exam for Independent IG Labs and Test Operators

The Insulating Glass Certification Council (IGCC) has implemented a new, online training program. It has long been a goal of the IGCC certification program to foster consistency in insulting glass standards and testing. The laboratory training exam has been created with a reduced-variability mindset, intended to establish consistency between test standards
and testing processes. To this end, IGCC has created a series of testing modules. The goal of these modules is to provide training to test operators, facilitate and drive consistency in the test methods, and create documented practices for testing.

For IGCC/Insulating Glass Manufacturers Alliance certification, the laboratory training exam will help to provide participants with a more consistent testing experience with less variability.

The concept grew out of a two-day 2014 IGCC laboratory workshop where
insulating glass test lab operators were invited to collaborate and participate
in round robin testing. The result was a need for consistent procedures and
understandings of test operations.

In an effort to answer this call, IGCC began creating an online tool that utilizes graphics and requires the use of computer animation. The IGCC committee found that a written test cannot enhance training like an interactive session can. Computer software compliments human understanding, creating an engaging and effective method of learning, according to the organization.

For optimal educational value, the test session is open book and all answers
are given after questions are asked. Program coordinator Katrina Stafford says, “This training is intended to help.”

Each question gives participants two opportunities to answer. If incorrect on
the first attempt, a hint is prompted for the next chance.

“Our goal is to help direct people to the testing standard and where the
information can be found. We don’t expect everything to be memorized.
We do, however, want people to know where to find the material when they
are either questioning the procedure or the results,” says Stafford.

ASHRAE Updates Residential Standard

ASHRAE has released an updated edition of ANSI/ASHRAE/ IES Standard 90.2-2018 Energy-Efficient Design of Low Rise Residential Buildings. The standard establishes minimum whole-building energy performance requirements (design, construction, and verification) for energy-efficient residential buildings.

The 2018 revision of Standard 90.2 outlines cost-effective residential building energy performance measures that are at least 50 percent more efficient than those defined by the 2006 International Energy Construction Code (IECC).

“Standard 90.2 provides a mechanism by which any residential building design can be easily evaluated against performance objectives,” says Theresa Weston, chair of the Standard 90.2 committee. “This update to the standard offers better alignment between this standard’s requirements and marketplace product availability as well as some revisions to improve the document’s clarity and internal consistency.”

Requirements in the 2018 edition of Standard 90.2 include, among others:

• Clarification for modeling software requirements;

• Guidance on the use of international climate data presented in ASHRAE Standard 169;

• A new normative appendix on proper installation techniques for critical thermal resistance building components;

• Improved prescriptive envelope performance data tables; and

• Clarifications to multi-zonal building air-leakage testing procedures.
