P i n u p s p a c e. Grasshopper. The Brute Force component, now included in TT Toolbox (release 1.4 and newer), provides an alternative means of running optimization routines in your Grasshopper workflows.

Optimization is used loosely here, as this tool is not using an algorithm to find the most optimal combination of sliders, but instead it solves ALL possible combinations of sliders that are connected to the input S. This component and method help to provide a means of looking at design space where you either want to see all possible permutations, or the total possible number of iterations is not so large that it warrants running the study in Galapagos or another optimization algorithm. Brute Force Grasshopper setup, with Listener component (all TT Toolbox components shown in orange). We have found this tool to work wonderfully when synced with our Galapagos Listener component (possibly hinting at a name change there). Taking that one step further, you may then write those values to Excel. Continue reading…

Architecture & Design News. LMN is excited to showcase model-building as part of the Seattle Architecture Foundation (SAF) 18th Annual Architectural Model Exhibit, running through Feb 5 at the Center for Architecture & Design at 1010 Western Ave.

Architecture & Design News

The theme of the exhibit is “Form,” interpreted in may ways by displays from more than 50 participants. LMN’s entry collects an array of 3D printed and CNC-routed study and presentation models, including a section of the Northgate Bicycle & Pedestrian Bridge (above). LMN’s modeling capabilities expanded in 2015 with the opening of the LMN Shop, an in-house digital fabrication workshop for making large-scale models, architectural component prototypes, and construction mockups for hands-on development with our clients and collaborators.

The Center for Architecture & Design is the new shared home for AIA Seattle, Seattle Architecture Foundation, Design in Public, and AIA Washington Council. Global Elevation Data. The wonderful SRTM project has the potential to provide global elevation data at up to 30m (1 arc-second) resolution, worldwide!

Global Elevation Data

For a description of the project, see the NASA/JPL SRTM site. Acquiring the data 90m (3 arc-second) elevation can be browsed and downloaded from the USGS EarthExplorer just look under "Digital Elevation: SRTM" or directly from their FTP site files are named according to latitude and longitude The GLCF is also a convenient way to browse and download SRTM data, in GeoTIFF format - for more information, see the GLCF SRTM page. They also offer direct FTP access. SRTM Search Results - ArcInfo ASCII. AEC Technology Symposium 2015: Data-Driven Design. Savannah Simulations. Designplaygrounds. Welcome to designalyze.com. HKS Architects - Flattening the World of Parametric Design. Matthew Kennedy Question: What do Frank Gehry, a car salesman and healthcare planners all have in common?

HKS Architects - Flattening the World of Parametric Design

Answer: Parametric Design First, let me explain what I mean by parametric design. Simply put, parametric design is a design approach that uses a list of form-generating criteria, or rules, resulting in creation of a three-dimensional building form that responds to the list of criteria and the associative impact the list of multiple criteria have upon one another. For example, a designer may be tasked with designing a room with a floor area between 120 and 160 square feet, with a skylight that has an area one quarter the size of the total floor area. The typical result of this process is easily seen in the architectural work of someone like Frank Gehry. The Routledge Companion for Architecture Design and Practice: Established ... UTCI Archives - James Ramsden. Beware of using the UTCI approximation at extreme values - James Ramsden.

The UTCI is one of the more popular ways of estimating the perceived levels of thermal comfort in a space.

Beware of using the UTCI approximation at extreme values - James Ramsden

In this previous post, I published some C# code that allows you to calculate the UTCI. This code accepts inputs of air temperature, mean radiant temperature, humidity and wind velocity, and returns an equivalent perceived temperature in degC. According to the original author here, it is only valid for certain input ranges, namely: Air speed must be betwee 0.5 and 17m/sMRT must be no less than 30C and no more than 70C of the air temperatureAir temperature must be between -50C and +50C I have been using this UTCI code quite a lot, assuming that the model was a suitable approximation if I kept within the specified input ranges.

However, this is not always the case. Setting up a test To test, I built a very quick document in Grasshopper. This seems very reasonable. Where it sometimes goes wrong. Climate Data Trajectories. In an earlier post, we focused on simpler ways to interact with climate data.

Climate Data Trajectories

By using a flexible interface, a designer can potentially identify visual patterns and parametric relationships in weather files. Since the previous post, we’ve worked with LMN’s sustainability team and learned of a recent Building Green lecture regarding EPW files. The presentation was by Christoph Reinhart of MIT, and in it he referred to some compelling research by the University of Southampton: the Climate Change World Weather File Generator. This is a robust body of work which uses various models to predict and interpolate future climates based on global warming trends. With a basic Excel format, a designer can import a weather file with TMY Data and export a weather file for the years 2020, 2050, and 2080: With these weather files, an architect or engineer may run energy simulations for future climates in addition to current ones.
