Archsim Energy Modeling for Grasshopper



Use Archsim Energy Modeling component for Grasshopper to quickly create multi-zone energy models and simulations for building design. This tool comes with an abstract thermal model class library and various functions such as “early design auto-zoning” and “automated intersections” that assist you with model creation, simulation and result visualization.  Currently, supported simulation engines are Energy Plus 8.0 and (TRNSYS 17). However, the open library allows you to extend the output functionality for any other simulation package.

UrbanDaylight availability simulations

The UrbanDaylight is a Rhino 5 and Grasshopper plug-in that allows designers to simulate and evaluate the daylight potential of large urban designs. The tool automates exterior DAYSIM simulations for all buildings in the city model. Given the solar radiation on the facades, it uses a generalized impulse response to compute the interior illumination on an hour-by-hour basis. This allows us to use the data for climate based metrics. You can download the paper and slides from the SimBuild 2012 presentation.

Daylighting – A DAYSIM interface for Rhino

Daylighting Beta is included in the plug-in. This extends Rhino with regular DAYSIM simulation functionality. Here is a link to the creators of the DAYSIM simulation engine.
