IBPSA-USA San Francisco Chapter welcomes all to the April 2016 event – Weather Data and Future Climate Impacts.

Presenters:
Ben Brannon – Arup
Benjamin is a professional engineer and building physics specialist. He leads the Arup San Francisco energy modeling skills with an emphasis on computational analytics of non-traditional building design.

Weather files consist of hourly times series of weather variables for a typical year based on historical observations, and are widely used for modeling energy use and human comfort in the built environment. However, since they are based on historical data, they are increasingly inaccurate tools for estimating the future performance of buildings and communities, especially those with life times exceeding 30 years. To address this shortcoming, “morphing” techniques derived from those described by Belcher et al have been used to transform the historical weather file data based on changes, or offsets, in the monthly averages of several climatic variables between a baseline period and a future period, for an ensemble of climate projections. The Weather File Module of the WeatherShift tool provides an intuitive user interface that allows the user to select a city, emissions scenario, future time period and warming percentile to obtain a projected weather file reflecting a plausible future climate.

Neil Bulger – Integral Group
Neil Bulger is a Principal at Integral Group where he leads the building performance team. He has worked on several NZE projects and provides energy, comfort, and optimization solutions.

Neil will present on some of the multi-family projects Integral has participated in where climate data and future climate data where key drivers for façade and mechanical system impacts. The projects will go over how to use simple models with morphing weather data.

Liam Buckley – IES VE
Liam Buckley will present on the various climate tools within IESVE. They include Customization of Weather Variables; Psychrometrics, Mahoney Analysis, Simulation Weather vs Design Weather, and more.

Title 24 2013 How Practitioners Are Managing

Mid April, we hosted a discussion with local members of IBPSA on Title 24 2013 and the changes in place for software and permit submission. Those who are aware of the changes that took place at the end of March are well aware, others may only be hearing about this through Architecture and Engineering affiliates and friends.

The IBPSA San Francisco meeting focused on Title 24 and experience to date for commercial building compliance, documentation, and permit submission. The goals were to discuss problems and any success stories in utilizing the new softwares available and establish any consensus for best practice or best ideas to try.

The discussion followed the following topics, past experience, any future plan, short term and long term goals for Software Usability, Permit Completion, and Submission and Review processes. We had a host of attendees from the major bay area engineering and consulting firms who shared how they have been adapting, what software they are currently using and any issues or ideas.

Here is a copy of the notes and plans by each company who attended:

Title 24 2013 IBPSA Discussion Notes 04-27-2015

Below are some resources on FAQs for software help, both from IES and CBECC-Com, as well as example documents on permit completion from San Francisco planning department documenting what sheets are needed when.

General Take-Aways from the Meeting

  • Takes two to ten times longer compared to Energy Pro old version! And two models instead of one. Version 4 LEED hasn’t accepted Title 24 equivalence yet so you need two versions.
  • Any additional points you get for CalGreen checklist they are allowing you to submit for LEED points.
  • The software and the speed of changing things is extremely slow with CBECC-COM.
  • The only way to get savings is in lighting or hot water. There is no savings in the envelope.

 

NORESCO (developers of CBECC-COM)

  • Do exceptional calculations from CBECC-COM by creating an EnergyPlus model from the IDF file from CBECC-COM. Script heat recovery for example in the IDF file, run it again in CBECC-COM as an exceptional calculation. Submit this to the CEC for exceptional calculation method. Exceptional calculation can also be created in IES.
  • 10 MB is a size limitation on CBECC-COM – output file size limitation
  • CBECC-COM – Version 3b –
    • Accepts larger file sizes
    • Better form generation than v3
    • Change in how unmet load hours are treated
    • Ventilation calculations are corrected
  • CBECC-COM – Version 4 –
    • heat recovery system and chilled beam
    • Late Summer 2015
    • They need more error messages in the log file (SEE their website for more information)

IES-VE

  • Check Title 24 FAQs on the website – iesve.com/softare/tilte24/tilte-24/faqs
  • 5% of IES queries are Title 24 related. Of that 85% iesve could work out, 15% were coordinated with CBEC-COM. Errors are 69% which is unusual, usually about 5%. HVAC is most common error (30%), installation (26%) (which version of which software) you can only use Version 3 if using IES-VE, Envelope (16%), Geometry (11%).

April 20th Title 24 for Practitioners Free Event

IBPSA USA San Francisco Chapter is partnering with the PG&E Center on a current “hot topic”-one of a kind live discussion about the Nonresidential 2013 T-24 code-please see more info below.

where: PG&E Center, 851 Howard St., San Francisco CA 94103

when: Monday, April 20th, 4-6pm PST.

Everyone is invited to join in person or via the got web meeting:

https://attendee.gotowebinar.com/register/7350181721297234178

Please respond directly to me and cc Bill Burke at the PG&E Center (WxB0@pge.com) if you are planning to attend in person so we provide proper accommodations for everyone.

“Title 24 compliance modeling paths and software have undergone major changes with the 2013 Energy Standards. These changes have created considerable confusion among building professionals and new challenges for energy modelers. What is actually required under the 2013 Standards? What software is approved for compliance? What are the various capabilities of different approved software? How have experienced modelers implemented new steps and processes, changing their work flow to assess loads, design systems, and document compliance? Design and energy modeling practitioners will describe and discuss their workflow under the 2013 Standards, sharing their experiences of what’s worked and what has not. Come prepared to ask questions and share your own experiences in what should be an informative discussion!”

Looking forward to your participation!
