endothermic morphologies

ted — Fri, 02 Dec 2011 01:55:06 +0000

Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries, even when the surrounding temperature is very different. This process is one aspect of homeostasis: a dynamic state of stability between an animal’s internal environment and its external environment.
Organisms can generally be divided into two types of thermoregulators, endotherms and ectotherms.

Endotherms create most of their heat via metabolic processes, and are colloquially referred to as warm-blooded. Ectotherms temperature comes mostly from the environment.

This set of experiments attempt to combine thermal-electric materials and heat pipe technology to actively thermoregulate an environment.

AMPS Mockup

ted — Mon, 21 Feb 2011 04:31:39 +0000

Full scale mockup of the Active Modular Phytoremediation System. This is both a visual mockup and a testing prototype we will use to collect data. It’ll be installed inside SOM’s office where we will track the rate of VOC removal, plants’ behavior and lighting requirements, and the automation of lighting, moisture sensing and irrigation systems.

climate visualization with Matlab

ted — Sun, 22 Aug 2010 18:38:51 +0000

This tutorial goes through the process of visualizing TMY3 (Typical Meteorological Year) data using Matlab.

A common problem with weather visualization using tools like Ecotect or Climate Consultant is they only visualize 1 set of data at a time. But the ability to combine different datasets is critical to material decisions and spatial organization strategies. Thus, this tool is created for the sole purpose of enabling architects to actively use weather data to make better design decisions.

The 4 small Matlab scripts are meant for educational purpose only and you can download them here.

Open ReadEPW.m
Line 2 reads (‘Country_City_WeatherStation.epw‘);
Change Country_City_WeatherStation.epw to a TMY3 data file you want to open, and click Run, the file will bring the weather into Matlab.
Open EPW2Hourly.m and click Run, the file will sort through all the variables and give them proper names.
Type in command:
plot(x,dbt,x,dpt);
to plot Dry Bulb Temperature and Dew Point Temperature on the same graph.

Open EPW2Daily.m and click Run to arrange the data into daily values.
Type in command:
pcolor(dbt);
to plot the Dry Bulb Temperature as a pseudo-color image.

Type in command:
Colormap(jet);
to change the color mapping of the plot
You may use the same commend to plot the following:

Direct Normal Radiation

Global Horizontal Radiation

Actual Vapour Content in Kg/Kg

Relative Humidity

Windspeed

Type in command:
[fx,fy]=gradient(dbt);
to calculate the rate of change of Dry Bulb Temperature.
Type in command:
quiver(x,y,fx,fy);
to plot the rate of change of Dry Bulb Temperature.

Open EPW_DiurnalSwing.m and click Run to calculate the diurnal swing.
Type in command:
x1 = 1:365;
To create a new variable x1.
Type in command:
plot(x1,dbtMax,x1,dbtMin);
to plot Maximum Dry Bulb Temperature and Minimum Dry Bulb Temperature on the same graph to see the daily temperature changes.

Type in command:
plot(x1,rhMax,x1,rhMin);
to plot Maximum Relative Humidity and Minimum Relative Humidity on the same graph to see the daily humidity changes.

Type in command:
plot(x1,kgprkgMax,x1,kgprkgMax);
to plot the Maximum Water Vapor Content and Minimum Water Vapor Content on the same graph.

insolar louver system

ted — Thu, 29 Oct 2009 19:00:48 +0000

This definition extends the GH powercopy to be parametrically associated with the solar geometry obtained through the insolar radiation algorithm. It is part of a larger series related to the idea of Environmental Parametrics.

GH powercopy

ted — Thu, 29 Oct 2009 17:24:13 +0000

This definition is inspired by David Fano’s Parametric Truss tutorial, which can be found here. This version extends the approach to the 3 dimensions by utilizing the normal vector of the surface. Please complete Fano’s tutorial before viewing this one.

insolar component population

ted — Thu, 29 Oct 2009 17:21:10 +0000

This is a follow up tutorial that shows the whole process of using the insolar definitions (analemma, day and current time) in conjunction with the mesh component population definition. It is a 2 step process and make use of box morph. It is part of a larger series related to the idea of Environmental Parametrics.

component population on mesh

ted — Thu, 29 Oct 2009 17:18:17 +0000

This file populates a set of geometric components (examples with 4 or 8 components included) on a colored mesh. The color information is a way to embed external data into the geometry and give you instant feedback about the perfomance. The data can come from Ecotect analysis, the sun system which is available here, or any other analysis software. Meshes do need to be quads.

image mapping on mesh

ted — Thu, 29 Oct 2009 17:13:41 +0000

This example shows how to map images onto NURBS surfaces and output as mesh. This is one part of a larger series that uses the color space method of component population, which as a conceptual framework, I will name this Environmental Parametrics here. It uses the RGB space as a way to to embed external data to create a dialogue with geometry, thus giving it an overall geometric intelligence

multipoint attractor on mesh

ted — Thu, 29 Oct 2009 17:09:16 +0000

This example file shows how to use 3 points (or as many as you want) to create a color mapping that can be used with the component population tutorial. As a conceptual framework, I will name this Environmental Parametrics here. It uses the RGB space as a way to to embed external data to create a dialogue with geometry, thus giving it an overall geometric intelligence
