Performance: Direct Beam Solar Study

Arch 100b 2013 Spring

Course Arch 100b
Date 2013/04/12
Learning Objectives In this session we will produce an analytical animation depicting the effectiveness of your facade design in terms of the allowance of direct beam solar radiation. An initial "base case" analysis will determine the performance of the facade as presented at the mid-project review. Following this first pass, we will then adjust our facade designs to block sun that is entering the building during overheated periods, and to allow sun if it is being blocked during underheated periods. We will then run a new analysis based on the redesign. Finally, we will use Photoshop to sequence the analysis images into a movie. We will then produce two boards for presentation on April 19th - one showing the original design and a set of renders showing the "problem", and another board showing the changed design and a set of renders showing the "solution". Final animations of the solution will also be handed in.

Light and Architecture

Light is only visible to us when it falls on a surface. Architecture is made of surfaces, giving the architect a great opportunity to construct space in terms of light. A basic framework is needed to consider how light enters and moves through a space, as well as strategies for combining light, space and program. When thermal considerations are also met, the resulting space has enormous potential to be memorable and meaningful.

Workflow: Create Direct Beam Solar Animation

The goal of this workflow is to demonstrate how a sun study animation can inform the designer as to what the sun is going to do in relation to the space at various times of year. Consideration of Thermal Comfort, Daylighting Components, and Poetics of Light is necessary to produce great spaces.

Exercise: Using a Sun Study Animation for Analysis and Design

Taking your current building design, run a solar animation on an interior view (as demonstrated in workflow). Change your design to either let more sun in or keep more sun out. Run a new animation to show how the changes are working. Repeat until you are happy with the results, then make a high quality animation. Lay this process out on two boards - one for before any design change and one for after your changes.
