2022 WV ASHRAE HPBD

Morning Program – ASHAE 90.1-2013

Standard 90.1 has been a benchmark for commercial building energy codes in the United States and a key basis for codes and standards around the world for more than 35 years. This standard provides the minimum requirements for energy-efficient design of most buildings, except low-rise residential buildings. It offers, in detail, the minimum energy efficiency requirements for design and construction of new buildings and their systems, new portions of buildings and their systems, and new systems and equipment in existing buildings, as well as criteria for determining compliance with these requirements. It is an indispensable reference for engineers and other professionals involved in design of buildings and building systems.

Mr Wallace will cover the design, plan review, inspection, and analysis of projects. He will provide a clear understanding and correct use of the requirements identified by these basic code provisions, tables, and categorizations. Participants will be able to apply the code in clear-cut situations and build their understanding of the intent of the code when asked to make code compliance decision,

The 90.1-2013 edition was expanded from the 2010 version to include new features and more detailed requirements, as well as incorporating changes from more than one hundred addenda.

Here is what is new in the 2013 edition:

• Revised, stricter opaque element and fenestration requirements at a reasonable level of cost-effectiveness
• Improvements to daylighting controls, space-by-space lighting power density limits, and thresholds for toplighting
• Revised equipment efficiencies for heat pumps, packaged terminal air conditioners (PTACs), single package vertical heat pumps and air conditioners (SPVHP and SPVAC), and evaporative condensers
• New provisions for commercial refrigeration equipment and improved controls for heat rejection and boiler equipment
• Improved requirements for expanded use of energy recovery, small-motor efficiencies, and fan power control and credits
• Improved equipment efficiencies for chillers
• Clarifications for the use of prescriptive provisions when performing building energy use modeling, and revisions to enhance capturing daylighting when performing modeling calculations
• A new alternate compliance path to Section 6, “Heating, Ventilating, and Air-Conditioning,” for computer room systems, developed with ASHRAE Technical Committee (TC) 9.9.
• A new requirement for sub-metering of major energy load systems

Afternoon Program

Mr Wallace will overview the newer versions of the 90.1 code. Specifically, the 2016. 2019, and preview the 2022 version. Owners and government bodies may elect to require compliance with the newer codes so basic code knowledge is helpful. Mr. Wallace will cover the key changes and the impact on energy and first cost. In the last hour we will have a panel and open discussion on the impact and enforcement of the energy codes in WV. Karen LaSure and Garrett Weaver from the State Energy Office will join in this  discussion. (Garrett Weaver is our WV ASHRAE 2022-23 Chapter President.)

ASHRAE 90.1 2016 edition comprises numerous energy-saving measures and incorporates changes from more than 125 addenda. It also includes the following:

Structural changes:

• A new Reference Standard Reproduction Annex 1 is provided at the end of the document. Section 5.1.4 now cites ASHRAE Standard 169 as the source for climatic data, and Annex 1 contains extracts of tables and figures from that standard for the reader’s convenience.
• Two new climate zones (0A/B) have been added to all prescriptive requirements tables.
• Many counties in the US have changed Climate Zones
• Significant technical content changes:

Building Envelope

• Envelope verification in support of reduced air infiltration and increased requirements for air leakage of overhead coiling doors.
• Increased stringency requirements for metal building roofs and walls, fenestration, and opaque doors.
• Improved clarity on defining exterior walls, building orientation, fault assumptions for the effective R-value of air spaces, and calculation procedures for insulating metal building walls.

Lighting

• Modified requirements for exterior and interior lighting power densities to reflect new lighting levels in the IES Lighting Handbook.
• Modified requirements for lighting control to add additional controls in some space types and options to others to allow easier application of advanced controls.

Mechanical

• Large, electrically driven chilled-water plants are now required to be monitored for electric energy use and efficiency.
• Changes to the requirements for VFDs on hydronic pumping systems
• Dedicated outdoor air systems now include both efficiency and rating requirements for compliance.
• Requirements are introduced for designs to include both use category and efficiency class.
• Requirement that air-cooled DX cooling units with economizers have a monitoring system to determine that the air economizer is working properly.
• Preceptive delta-T requirement for chilled water coils.

Energy Cost Budget (ECB) and Modeling

• Appendix G now can be used as a path for compliance with the standard.
• Changes to elevator, motor, and refrigeration baselines; changes to the baseline for existing building projects; and changes to specific opaque assemblies for the baseline envelope model. Modeling rule changes were made to heat pump auxiliary heat, economizer shutoff, lighting controls, humidification systems, cooling towers, and the simulation of preheat coils.

Note: LEED® 4.1 requires compliance with ASHRAE 90.1-2016.

The 2019 edition includes various modifications and clarifications to improve internal consistency and to standardize the structure and language of the document.

Significant changes to requirements include the following

Administration and Enforcement

• New commissioning requirements in accordance with ASHRAE/IES Standard 202ucts for vertical fenestration

Building Envelope

• Combined categories of “nonmetal framed” and “metal framed” products for vertical fenestration
• Upgraded minimum criteria for SHGC and U-factor across all climate zones
• Revised air leakage section to clarify compliance
• Refined exceptions related to vestibules, added new option, and associated criteria for using air curtains

Lighting

• Modified lighting power allowances for Space-by-Space Method and the Building Area Method
• New simplified method for lighting for contractors and designers of renovated office buildings and retail buildings up to 25,000 ft2 (2300 m2).
• Updated lighting control requirements for parking garages to account for the use of LEDs
• Updated daylight responsive requirements, added definition for “continuous dimming” based on NEMA LSD-64-2014
• Clarified side-lighting requirements and associated exceptions

Mechanical

• New requirements to allow the option of using ASHRAE Standard 90.4 instead of ASHRAE Standard 90.1 in computer rooms that have an IT equipment load larger than 10 kW
• Added pump definitions, requirements, and efficiency tables to the standard for the first time
• New equipment efficiency requirement tables and changes to existing tables
• Replaced fan efficiency grade (FEG) efficiency metric with fan energy index (FEI)
• New requirements for reporting fan power for ceiling fans and updated requirements for fan motor selections to increase design options for load-matching variable-speed fan applications
• New energy recovery requirements for high-rise residential building
• New requirement for condenser heat recovery for acute care inpatient hospitals

Energy Cost Budget (ECB) Method (Section 11)

• Numerous changes to ensure continuity
• Set baseline for on-site electricity generation systems

Performance Rating Method (Appendix G)

• Clarified Appendix G rules and corresponding baseline efficiency requirement when combining multiple thermal zones into a single thermal block
• New explicit heating and cooling COPs without fan for baseline packaged cooling equipment
• New rules for modeling impact of automatic receptacle controls
• Set more specific baseline rules for infiltration modeling
• Clarified how plant and coil sizing should be performed
• Updated building performance factors
