ASHRAE BPAC & SimBuild 2020 – Looking Ahead

ASHRAE BPAC & Simbuild 2020: Virtual Conference

EDSL and ESTECO to present at ASHRAE BPAC & SimBuild 2020

Be sure to watch our presentation on Thursday, Oct 1.  We will be the third presenter in Seminar 6, which begins at 11:30am ET.  If you haven’t registered for the conference, you can do so here
 
We are running a promotion during the conference, please get in touch to find out more, arrange a trial, or request a demonstration. 
As part of the upcoming Building Performnce Analysis Simbuild conference, we will be presenting some of our ongoing research on multiobjective optimization, conducted in collaboration with ESTECO.
ESTECO is a software company focused on tools for engineering disciplines.  We teamed them to leverage the power of their modeFrontier software, known for its multiobjective optimization capabilities.  While typically used in structural and other engineering disciplines, we wanted to demonstrate its usefulness in energy modeling.
 
Why consider multiobjective optimization?   For starters, design itself is about understanding tradeoffs and benefits of an array of solutions, and making decisions that are best suited to the particular combination of considerations at hand.  It is the balancing act of those benefits and tradeoffs that defines a successful project.
Our proof of concept research studied balancing thermal efficiency and occupant comfort of a classroom.  We defined the problem as follows:
 
thermal efficiency = minimizing the heating and cooling loads by maximizing natural ventilation
Variables:
Rear of classroom: 1 row of windows with 3 possible states of openness
  • Open max (20% of window area due to safety restrictors)
  • Open mid (10% of window area due to safety restrictors)
  • Closed
Front of classroom:  3 rows of windows
  • Front top
  • Front mid
  • Front bottom 
Each row has the same 3 possible states of openness as described above.
 
Room orientation: 0-364 degrees rotation, in increments of 1 degree
While performing this type of study in Excel is possible, it is often prohibitively complex, time intensive, or both.  With 72 orientations and three choices of openness, there are nearly 6,000 combinations to evaluate.  If we included two different roof insulation options, the number of combinations would have increased to nearly 12,000.  Adding three glass options would have included about 50,000 combinations.  Clearly these considersations would be valuable to incoroprate, but would require a method other than spreadsheets to analyse the data and manage the results.
 
For thermal comfort, we limited the solution set to contain options whose PMV was between -1 and 1.  We also limited the total percentage of occupied hours that fell above the high temperature threshold of 25C/ 77F – a simplified version of overheating analysis.  
For the results of this research, please be sure to watch our presentation on Thursday, Oct 1.  Registration details are at the top of the page.
 
Our goal for this presentation was twofold.  First, to demonstrate the benefits of using multiobjective optimization to solve sustainability-related design problems quickly and efficiently.  Our second goal was to uncover potential, nonintuitive solutions that may have otherwise remained uninvestigated.

2019 ASHRAE Building Performance Analysis Conference - Preconference Workshops

Effective simulation throughout the building life cycle with Tas (presented by EDSL)

On Tuesday morning, we held a pre-conference workshop with attendees from high performance building design teams, firm leaders, energy analysts, and other related backgrounds.  Michael Sawford and Robert Yori reviewed how Tas can be used throughout the ASHRAE 209 cycles.  This included a general introduction to Tas, BIM and BEM interoperability workflows, and whole building simulation using Tas Systems – our component based tool for simulating innovative and advanced plant room and air-side systems. 
 
The workshop included live simulations of projects, systems inspection using Tas Systems, and a case study of a post occupancy performance analysis. To wrap up, attendees stayed for lunch and were joined by our afternoon workshop participants for some networking and knowledge sharing.  

Crafting your story with building performance simulation data (sponsored by EDSL)

The afternoon workshop was well attended with some last minute sign-ups taking the total to 23. 4 attendees from our morning workshop also joined us for the afternoon which turned out to be a great workshop led by Alejandra Menchaca (Thornton Tomasetti), Kjell Anderson (LMN Architects) and Aman Singhvi (AECOM).

2019 ASHRAE Building Performance Analysis Conference

EDSL were once again pleased to sponsor 2019’s ASHRAE BPAC event, which was held in Denver last month.   Many thanks to everyone who attended our workshops, stopped by our table, and took a few minutes to chat with us about Tas.  In comparison with last year’s ASHRAE/ IBPSA joint meeting, our conversations trended more toward Tas’ functionality and its capabilities, while last year we spent a lot of time introducing Tas to people.  It’s rewarding to see that Tas is increasingly recognized and being used in North America.

In addition to our outreach about Tas, EDSL was involved in a number of the program sessions throughout the week.  We proudly contributed to Amir Rezaei’s “Geometry Translation – the Good, the Bad, and The Ugly” session, offering our thoughts and experiences with BIM to BEM, what’s working, and what would be improved upon.  We were also given the opportunity to opine on the state of software and energy modeling in the Vendor Town Hall, where we touched on Tas’ robustness, speed, and accessibility.  
 
EDSL also continued our active participation through Project StaSIO’s third year and 2nd annual competition, helping to organize this year’s competition, manage the jury selection, and improve the website.  And we’re not finished yet – as a result of this year’s outstanding entries, we have some new ideas in store for next year’s competition.  So stay tuned!

BuildingEnergy NYC 2019

EDSL USA at BuildingEnergy NYC 2019

EDSL at NESEA’s BuildingEnergy NYC Conference + Trade Show in September, held in downtown Manhattan.
 
This was our second opportunity to be involved with NESEA, and we were glad to be involved once again in the community by sponsoring BuildingEnergy NYC.  Being in EDSL USA’s home city, it was the perfect opportunity to announce our Tas Workshops.  Throughout the week of October 21 we will be hosting a series of workshops that introduce Tas, including both general and deeper-dive sessions.

We hope that many of the BuildingEnergy NYC attendees will be able to join us along with other building performance analysts and educators in building science from in and around the New York area.  There are still some seats available, so register now if you’d like to join us.

2019 ASHRAE Building Performance Analysis Conference & Project StaSIO

2019 ASHRAE Building Performance Analysis Conference and Project StaSIO

After a tremendously successful first year of IBPSA-USA’s Project StaSIO, EDSL USA VP Michael Sawford is looking forward to expanding its reach and offering.  “Last September’s Building Performance Analysis Conference and SimBuild was the perfect opportunity to introduce Project StaSIO to the world, and the competition provided a great way to kick start the resource for the BEM community.

This year promises some exciting advancements – new leaders have joined, enabling the committee to expand its range and potential impact. Thanks in large part to the DOE, who funded the initiative, we are redeveloping our online presence, and refreshing the website to create an engaging, valuable, easy-to-use resource for inspiration and research. 

2019 ASHRAE Building Performance Analysis Conference - Pre-conference Workshops

In addition to our involvement on the StaSIO committee, EDSL is supporting the initiative and its goals in several other ways. At ASHRAE BPAC 2019, we are sponsoring the pre-conference course Crafting your story with building performance simulation data, led by experts from Thornton Tomasetti and LMN Architects.  We will also be running a pre-conference course entitled Effective simulation throughout the building life cycle with Tas”.  Both worships will take place on Tuesday, September 24.

DOE BTO Peer Review 2019

US Department of Energy's Building Technologies Office BEM Peer Review 2019

Along with other industry leaders and stakeholders, EDSL’s Michael Sawford was invited as a reviewer for the DOE’s BTO BEM Peer Review. The review took place April 16th last month, where participants were asked to review and advise the current range of BTO projects with the goal of furthering research and the advancement of building simulation in the design, operations, and maintenance of buildings.

BTO's Request for Information

The Building Technologies Office has produced a request for information and provided all the necessary information on the EERE exchange website for the wider BEM community to get involved and participate. IBPSA-USA has also provided a useful survey for the community to get involved and respond to the RFI.

SimAUD 2019

EDSL USA at SimAUD 2019

EDSL was at SimAUD 2019, the symposium on simulation for architecture and urban design.
 
This was EDSL’s first SimAUD event.
 
Working with professionals, researchers, and students in the fields of architecture, engineering, and sustainability sends a strong message about the power and effectiveness of transdisciplinary collaboration, analysis, and simulation.” said Michael Sawford, Vice President of EDSL USA.
 
Here are a few items we found of particular interest:
  • Interoperability remains a sticking point in transdisciplinary collaboration workflows.  One of EDSL’s objectives is to minimize barriers across tools and support informational continuity.  Each discipline can work with their best-suited applications while also being able to communicate upstream and downstream with their peers.  To this end, Tas software supports two-way interoperability with EnergyPlus -based tools, and the ability to import eQuest model data.  
  • Parametric optimization is always a popular topic at research conferences, and Tas currently supports LBNL’s GenOpt tool for multiobjective optimizations.   Thanks to the conference presentations and feedback, we are now researching additional optimization algorithms for enhanced flexibility.  
  • A number of presentations focused on reducing simulation times through model abstraction and reducing the number of simulations required.  Tas software can deliver results more quickly thanks to its own fast and robust simulation engine, allowing users to explore the same size design space more quickly, or a larger design space in the same amount of time.  Coupled with the strategies presented could lead to even quicker results.

EDSL's Tas software at Georgia Tech

Georgia Tech was an ideal venue for SimAUD, thanks in particular to their innovative school of architecture led by Scott Marble.  Dr Dennis Shelden, head of the Digital Building Lab, gave a thoughtful overview of simulation and technology’s trajectory through the past thirty years, and Dr Fried Augenbroe wowed us with an inspirational collection of his reflections about building simulation and its effectiveness.  
 
We are especially proud that EDSL’s Tas software is being taught in Dr Augenbroe’s High Performance Building Lab, and are working with the Lab on the Living Building Challenge certification for the new Kendeda Building for Innovative Sustainable Design.  

BuildingEnergy Boston 2019

EDSL USA at BuildingEnergy Boston 2019

EDSL was at NESEA’s BuildingEnergy Boston Conference + Trade Show, it’s been a full week and we are finally getting caught up.

As this was EDSL’s first NESEA event, we weren’t sure what to expect. The organization was great and we were welcomed by the community. We had hoped to attend more classes but thanks to interest at the booth we were afforded little time. It was encouraging to see the diversity of attendees ranging from policy makers, product manufacturers, architects, engineers, and everything in between. The culmination of many discussions with people from diverse backgrounds lead to possibilities for the use of our software in traditional applications and in new directions.

We are very excited to participate in BuildingEnergy New York as it is our home base in the US. We are hoping to build a strong local user group and are looking forward to being involved in the NESEA community going forward.

Energy, CO2, and Embodied Carbon - how the AEC industry can turn buildings into carbon sinks

Michelle Apigian (ICON Arcitecture) and James Petersen (Petersen Engineering) opened the Keynote session ‘Carbon Drawdown Now! Turning Buildings into Carbon Sinks‘ presented by Chris Magwood (Endeavour Centre), Ace McArleton & Jacob Racusin (New Frameworks). The keynote focussed on how buildings have the potential to become the world’s fifth largest carbon sink, rather than a leading emitter and how the work of the AEC industry is essential for climate justice and social equity.
