Please JOIN WVASHRAE for our
2022 WV High Performance Building Day (HPBD)
8:00 AM – 4:00 PM EDT
This event is In-person with a Virtual Attendance Option. In-Person Attendees will receive lunch
ASHRAE Learning Institute Instructor, Mack Wallace, will be teaching the course. As an added bonus, Mr Wallace will overview the more recent ASHRAE 90.1 codes (2016, 2019 and a preview of the 2022). This course should help you meet the code requirements and advise clients on the impact of selecting one of these codes for a building. Each 90.1 version is more energy efficient than the previous or older versions. Please Note: ASHRAE 90.1 is the only State adopted commercial building energy code enforced in WV.
Our lunch speaker will present “Looking into the Future”. Paula Guffey, CMTA, will give an update on WV Owner Adoption of High Performance Design to include EUI impact, economic/cost impact, when and why do onsite renewables (solar) for zero energy, and the impact of utility rate changes on building operations.
Lead Sponsors for our event:
This HPBD event is for anyone involved with commercial buildings in WV. Design and operating engineers, owners, architects, code officials, contractors, manufacturers, and any others seeking an understanding of the WV Energy Code requirements. The WV HPBD offers professional and personal growth that you are seeking, so do not let it pass you by!
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
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:
- 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:
- 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.
- 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.
- 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
