Section was updated primarily for the following reasons:

 1)    To define more complete strainer requirements, including specific screen size requirements for various services and pipe sizes.

Sections were updated primarily for the following reasons:

1)      To relocate the Acronym List to a more General location Div1, since it covers equipment from many Divisions.

2)      The list was reorganized first with respect to the associated Specification/Standard Section number and then alphabetically within those sections.   

3)      To more closely follow common equipment acronyms generally accepted and used in the industry such as:

a.       ASHRAE 2009 Fundamentals

b.      US National CAD Standards.

4)      To reduce common coordination problems arising during design development and shop drawings review causing frustration among design consultants, PSU staff and contractors.  Examples include:

a.       “AHU” for Air Handling Unit in lieu of prior “ACF” (Air Conditioning Fan).  A Fan is a single component of a larger Air Handling Unit assembly with many components that performs the function of conditioning air.  Also, it is common to associate “Air Conditioning” unit with packaged DX unitary equipment and “Air Handling” unit with hydronic sources of heating and cooling.

b.      “MAU” for Makeup Air Unit in lieu of prior  “SFN” (Supply FaN) for the function of 100% outside air for makeup supply.  Again, technically a Supply Fan is a single component of a larger Unit assembly with many components that performs the overall function.  In larger units, one might have multiple, parallel “supply fans” in any sort of AHU or MAU or RTU, etc.  Using MAU to designate that function helps avoid confusion with limited function of a supply fan as a component.

5)      In general suffixes can be added to give acronyms some additional flexibility to allow more detailed descriptions of specific type or use for purposes of scheduling, specification grouping and for control tag purposes. 

6)      Individual equipment numbering:  The goal is to give each piece of equipment its own ID tag by type/subtype category and then either sequentially within each category (for primary equipment) or by room location of control sensor it serves (for terminal equipment).  Each subtype of HVAC pump is sequentially numbered within its fluid service type.  In other words, chilled water pumps are to be numbered sequentially within that category separate from hot water pumps and condenser water pumps, etc.   

7)      Design Professional must coordinate ID and equipment numbering scheme with OPP staff to improve and maintain consistency.

Note the following from ASHRAE Journal, June 2010

Summary
The intent of the energy efficiency section is to significantly reduce the energy consumption of new buildings through reductions in energy losses through the
building envelope, increased efficiencies in mechanical systems, reduced lighting loads, and other energy saving measures. Standard 189.1 requires that buildings comply with Standard 90.1-2007 and then, in general, adds more stringent requirements. Standard 189.1 requires that either on-site renewable energy is used as a prescriptive option, that renewable energy certificates are purchased (only allowed in some cases), or that the building complies with the performance option and uses additional energy-saving measures to make up the deficiency from not using on-site renewable energy.

Conclusions
Based on an initial analysis, Standard 189.1 yields significant energy savings over previous standards. In a weighted average, savings are approximately 30% relative to Standard 90.1-2007, with roughly one-third of those savings attributable to renewable energy and two-thirds attributable to energy efficiency.
