ANSI Approves Changes to ASHRAE Energy Conservation and Network Standards

ANSI has recently approved eight addenda to ASHRAE's energy conservation and building controls network standards. These include five addenda to ANSI/ASHRAE/IESNA Standard 90.1-2001, Energy Standard for Buildings Except Low-Rise Residential Buildings and three addenda to ANSI/ASHRAE Standard 135-2001, BACnet - A Data Communication Protocol for Building Automation and Control Networks.

ANSI has recently approved eight addenda to ASHRAE's energy conservation and building controls network standards. These include five addenda to ANSI/ASHRAE/IESNA Standard 90.1-2001, Energy Standard for Buildings Except Low-Rise Residential Buildings and three addenda to ANSI/ASHRAE Standard 135-2001, BACnet - A Data Communication Protocol for Building Automation and Control Networks.

  • Addendum 90.1h updates Section 12 references and the test procedure references in sections that cover building material thermal properties and assembly U-factors.

  • 90.1p focuses on keeping building energy simulation programs bug-free. This addendum requires the programs to be tested with ANSI/ASHRAE Standard 140-2001, Standard Method of Test for the Evaluation of Building Energy Analysis Computer Programs .

  • 90.1o revises an exception to Section 6.3.1., economizers, so that it only applies to heat recovery systems required by Section 6.3.6.2., heat recovery for service water heating.

  • 90.1r adds return duct insulation requirements.

  • 90.1s revises exceptions (g) and (i) in Section 6.3.6.1., exhaust air energy recovery.

  • Addendum 135a changes the way BACnet systems represent and maintain schedules.

  • 135c contains eight new features including life safety objects and services enhancements and the ability to represent utility meters and other measuring devices that provide pulsed outputs.

  • 135d focuses on how to interconnect BACnet devices with devices that use the EIB/Konnex protocol.

All of the addenda are available for free via the "Standards Addenda" shortcut at www.ashrae.org .



Durability is Key

"Where is the bathroom?" is one of the key phrases people are told to learn when traveling to a foreign country—and with good reason.

In a recent survey of more than 600 International Facility Management Assn. (IFMA) members, commissioned by Bradley Corp., Menomonee Falls, Wis., almost three-quarters responded that they believe restrooms are the most frequently visited common areas of a building. An even higher number—85%—responded that durability is the most important design attribute of restrooms. Ease of cleaning and ADA-compliance were a close second and third, with 84% and 80%, respectively. Respondents revealed that low maintenance is also important.

According to the survey, facility managers also feel that restrooms are one of the number one targets for facility complaints; users are most concerned with restroom cleanliness. And hands-free technology is the most popular restroom design trend.
