ACCA Manual J Mobile-Wrightsoft
Friday, September 2, 2022 (9:00 AM - 12:00 PM) (PDT)
This half-day webinar builds on the Manual J and N materials which are prerequisites to this program. The session centers on the unique residential loads and energy code encountered in the Dry Climate of California. Please download a copy of Wrightsoft (Demo Version) prior to the webinar. The material is designed for HVAC Contractors, Designers, Energy consultants and anyone interested in determining building loads and determining the correct size of heating and cooling equipment. This process will reduce peak loads in the state of California and improve efficiency and comfort.
During the session, a sample plan is entered into Wrightsoft first using the 1975 code, since many homes meet these criteria it provides a touchstone for contractors in equipment sizing. The plan is then altered to meet the 2019 Energy Code. This allows attendees to compare the loads generated by Wrightsoft in Manual D and provides a practical opportunity to the effect the energy code has on Equipment sizes. Manufacture ‘Expanded Product Data’ Sheets are reviewed, and attendees are helped to use the correct qualifiers for California Code and Climate. Several examples are covered demonstrating the correct sizing procedure and differences in how charts and tables may look different but have the same information in an alternate format. ASHRAE 62.2 Residential ventilation requirements are reviewed and are incorporated into the Wrightsoft program. Internal loads are defined for the room-by-room design based on appliances and occupancy.
