Jifto - Sustainability Assessments by Henning Larsen Architects

wow, this looks promising. i can empathize with the frustration at being the computational team who has to do these simulations (which often lag behind the design process).

it looks like many of the referenced standards are European standards. are there plans to implement standards from North America, ie LEED?

comfort depends on surface temperatures as well as wind speed, sun exposure, ambient air temps. how do you account for the emissivity of different materials, and can we import our own materials?

The underlying calculation methods are physics based and thus location agnostic. We are gradually adding support for easier presentation of results to better support local regulations or certification schemes. Which specific aspects of LEED would you like jifto to support?

The current version of the thermal comfort engine already takes into account ambient temperature, humidity, MRT, direct solar exposure and wind speed. MRT currently assumes a single material applied to all objects in the scene, but a comprehensive material library is coming in 2 weeks from now. You will then be able to create custom materials with adjustable parameters.

oof, i’m not actively calculating LEED certification, so i can’t say which area of LEED would be most suited to this type of tool. but it’s a significant certification scheme in NA.

i appreciate the results panel showing standard-agnostic results so it’s easier to understand what’s happening. can’t wait to see the material library. coincidentally, we are looking for a wind-simulation/microclimate tool for our office, and this one seems promising

A short teaser of how to work with vegetation and future climate projections to optimize outdoor spaces for thermal comfort:

This doesnt show in my package manager for rhino 8. almost all the other addons do. Any idea whats going on?

jifto requires Rhino 8.21 installed for it to show up in the Package Manager.

jifto 1.0 is out
And it is all about trust.

We want sustainability analysis to feel fast, not tedious. But fast needs proof.

Several of you asked for exactly that. So this release ships two validation studies – charts, tables, and a lot more numbers than we had planned for.

TLDR – jifto simulates pedestrian wind speeds within ~5% of a physical wind tunnel. Sun-hours, shadows, and energy gains are physically correct.

For the curious ones who enjoy a technical deep-dive:

We now have a live-Grasshopper connector to stay in the design flow without having to bake anything. You can create live analysis and context objects for all our simulation modules directly in GH.

We’ve added a new module to analyze architectural views. It helps answer the question what someone standing in a space can actually see.

You can also publish all analysis results directly to a Miro board shared with your team or clients.

And for the ones who are new to jifto, we’ve added more ways to get you up to speed fast:
