The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) held their annual conference last week and InfoComm was there!
“Sustainability Knows No Borders!” was the appropriately themed conference consisting of five days of standards-writing, technical presentations and committee meetings addressing commercial building sustainability internationally. The following are some items of interest to our industry:
- The GreenGuide, ASHRAE’s Handbook on “green” technologies, was discussed at its sponsoring Technical Committee (TC) meeting in an attempt to make it more relevant and timely. It was suggested the GreenGuide may be more useful as a major ASHRAE online document that addresses ALL green standards and guides. A possible companion piece may a “green wiki” for ASHRAE member refinement and additions. Another thought was to turn the book in to a “best practices” for ASHRAE sustainability design criteria. Consideration will be given to use the GreenGuide for High Performance Building designer certification.
- TC 7.5 Smart Building Systems met during the conference and announced that the ASHRAE Board has approved development of a new chapter in the Applications Handbook to be titled “Smart Building Systems.” Four sections are proposed: 1.smart technologies for building systems; 2. sensing and actuating systems (wireless); 3. automated fault diagnostic detection; and 4.smart grid integration. An additional section was proposed to cover integration of IT systems with traditional building systems. The proposed timeline suggests publication no earlier than 2015, but there is potential for an electronic version to be out by 2013. It appears that ASHRAE’s Smart Building Technology (SBT)/Intelligent Building Technology (IBT) focus is centered on wireless technology.
- ASHRAE 189.2 Design, Construction and Operation of Sustainable High-Performance Health Care Facilities, an extension to ANSI/ASHRAE/USGBC/IES Standard 189.1-2009, Standard for the Design High-Performance Green Buildings, is still under development with a first draft recently sent out as an APR (advanced public review). Forty comments were returned, mostly stating that the standard is not needed. A third 189.2 draft is proposed to come out soon. It is important to note that the sustainability/green/energy efficiency conversation is moving from prescriptive/performance standards to outcome-based standards. Outcome-based standards set time-based energy budgets for building operation. This is total whole building energy, not just HVAC/lighting budgets, and would include all energy used for AV systems.
Further, this concept/proposal involves post Certificate of Occupancy (CoO) provision that requires inspection, auditing and reporting after the building is occupied and on a regular and ongoing basis.
ASHRAE Publications with Sustainability Content
2009 Fundamentals Volume — Chapter 8 “Thermal Comfort,” Chapter 9 “Indoor Environmental Health,” Chapter 17 “Energy Resources,” Chapter 27 “Ventilation and Infiltration.”
2011 HVAC Applications Volume — Chapter 32 “Geothermal Energy,” Chapter 33 “Solar Energy Use,” Chapter 35 “Energy Use and Management,” Chapter 47 “Sound and Vibration Control.”
ASHRAE GreenGuide — This nearly 200-page green guide offers essential reference and guidance to HVAC&R system designers involved in green or sustainable building design. The GreenGuide is a step-by-step manual for the entire building lifecycle, from the very earliest stages of a green building design project and through to the resulting structure’s construction, operation, maintenance and eventual demolition.
Advanced Energy Design Guide For Small Office Buildings — For developing energy-efficient buildings, the Advanced Energy Design Guide provides a sensible approach by including practical products and readily-available, “off-the-shelf” technology. The guide offers all the tools you need to create an energy-efficient building where the owners will see a 30% energy savings compared to buildings that only meet the minimum requirements of Standard 90.1.
Standard 189.1-2009 — Standard for the Design of High-Performance Green Buildings Except Low-Rise Residential Buildings, a jurisdictional compliance option of the International Green Construction Code (IgCC), covers the key topic areas of sustainability, water-use efficiency, energy efficiency, indoor environmental quality and the building’s effect on the atmosphere, materials and resources.
189.1 Users Manual — The user’s manual helps users of Standard 189.1-2009 understand its principles and requirements and how to comply with them.
Standard 90.1-2010 – Energy Standard for Buildings Except Low-Rise Residential Buildings — The purpose of this standard is to provide minimum requirements for the energy-efficient design of buildings except low-rise residential buildings.
Standard 90.1-2010 User’s Manual — This user’s manual provides detailed instruction for the design of commercial and high-rise residential buildings to ensure their compliance with ANSI/ASHRAE/IESNA Standard 90.1-2004.
Standard 90.2-2007 – Energy-Efficient Design of Low-Rise Residential Buildings — The purpose of this standard is to provide minimum requirements for the energy-efficient design of residential buildings.
Procedures for Commercial Building Energy Audits — provides purchasers and providers of energy audit services with a complete definition of good procedures for an energy survey and analysis.
Standard 55-2010 — Thermal Environmental Conditions for Human Occupancy— This standard specifies the combinations of indoor space environment and personal factors that will produce thermal environmental conditions acceptable to 80% or more of the occupants within a space.
Ventilation for Acceptable Indoor Air Quality — The purpose of this standard is to specify minimum ventilation rates and indoor air quality that will be acceptable to human occupants and are intended to minimize the potential for adverse health effects.
Standard 62.2-2007 – Ventilation and Acceptable Indoor Air Quality in Low-Rise Residential Buildings — This standard defines the roles of and minimum requirements for mechanical and natural ventilation systems and the building envelope intended to provide acceptable indoor air quality in low-rise residential buildings.
IAQ Applications — A quarterly news journal designed to bridge the gap between research and application, so content is geared toward information that can be applied in real-world situations.
