displaying Building Emissions Performance Standard (BEPS) targets

[danrademacher]

Conduct preliminary research on design solutions for displaying Building Emissions Performance Standard (BEPS) targets in building reports for buildings; solution to be implemented in a subsequent scope of work

[danrademacher]

Here's what we do for the state standard:

Here's the writeup of the Seattle standard: https://www.seattle.gov/environment/climate-change/buildings-and-energy/building-performance-standards

For the state, we have:

• estimated compliance Date
• estimated EUI target

Here's what the city targets look like:

Notes from https://www.seattle.gov/documents/Departments/OSE/Building%20Energy/BEPS-Proposed-Policy-Guide.pdf

How many buildings?

BEPS covers existing nonresidential & multifamily buildings greater than 20,000 square feet, excluding parking. In Seattle, this is about 1,650 nonresidential buildings, largely downtown and in dense neighborhoods, like high and mid-rise offices, hotels, schools, large warehouses, and retail, and about 1,885 multifamily buildings (typically those with about 20 units on average or more). About 600 large buildings on campuses like colleges or hospitals are also covered. This is consistent with buildings that already must comply with Seattle Energy Benchmarking & Reporting and the WA CBPS. Buildings used for industrial and manufacturing purposes are exempt.

So that sounds like about 4,135 buildings, 1650+1885+600.

interesting in that currently, the 2021 data has 3600 buildings. They are adding more now, but in general it sounds like 100% of buildings in the map will have this section.

There's a complex rollout schedule:

Still, we could sidestep some of that complexity if the upstream data can boil it down similarly to the statewide targets:

1. compliance date for 5-year target
2. compliance date for net zero
3. 5 year greenhouse gas intensity target (GHGIT)
4. Net-zero greenhouse gas intensity target (GHGIT) -- or is this literally just ZERO?

We currently symbolize the map by GHG Intensity:

Is that the same as GHGIT?

The field is total_ghg_emissions_intensity

[danrademacher]

• Focus on 2031 targets for this, not the later net zero targets.
• It does apply to all buildings in the system
• Once the law is passed, that table of GHGs will settle down and be final

[danrademacher]

Since the 2031 compliance date is the same for everyone, they only new data we need is:

• 5 year greenhouse gas intensity target (GHGIT)

[danrademacher]

Concept

• Reuse as much of statewide as possible, for easier comprehension
• Include copy to explain difference between EUI and GHGI

Questions

• Place targets next to each other or next to the relevant EUI and GHG charts?
• Should this "New" be replaced by a new message about the city requirement?

[danrademacher]

Here's a Figma of the new GHGI target: https://www.figma.com/file/s7MBd0TzlKiuyMVurkQCuP/Seattle-Buildings?type=design&node-id=1%3A2&mode=design&t=32JGBpJ2k0vFtYjk-1

This seems pretty straightforward and works fine. Easyish to do, easy to understand.

Important note here: "solution to be implemented in a subsequent scope of work"

So if they accept this, maybe this whole task is done!

HI Mike, Here's a mockup of what we propose for the BEPS section of the report:https://www.figma.com/file/s7MBd0TzlKiuyMVurkQCuP/Seattle-Buildings?type=design&node-id=0-1&mode=design&t=32JGBpJ2k0vFtYjk-0

Notes in the margin highlight what is added/changed. One thing I just reminded myself of is the note "solution to be implemented in a subsequent scope of work." Our proposal here is to reuse and adapt the statewide energy performance standard. And that's not just because it's easier to implement. We also think it's easier for users, since they can see, in similar presentations, how close they are to meeting each of two standards. Note that, as we understand it, every building would have the city BEPS section but we would continue to show statewide by existing logic that applies only to certain larger buildings. Best,Dan
