Experiment 1: Draw the Light Objective: Understand and graphically represent how a “Master� architect manipulates daylight and space by analyzing a relevant daylit project Summery: The Mt. Angel library is a daylit space designed by Alvar Alto. The main space of the library is top lit and provides lighting throughout the space.

Experiment 2: Building Daylighting models Objective: Build a simple physical model, explore daylight as a light source, begin to understand the relationship between daylight apertures and interior surfaces.

Twenty one different lighting conditions
Project Summery: We first decided on a simple shoebox shape, approximately 18� but 20� and then decided what type of lighting should be illustrated. We wanted to cover side lighting, back lighting, and two forms of top lighting. The side lighting has a filter on it to act like a series of translucent panels. The light tube above also uses the same filter and has a similar translucent. The radiating skylights so not have a filter and serve as a primary light source along the curve wall in the back. The ramp adds a dynamic element to the scene and helps tell a visual story.

Experiment 3: Build and Analyze a Physical Model of a Masters Space Objective: Build and analyze an exquisite physical model of a primary space from a famous daylit building. Project Summery: This was a group project consisting of four members. The space that we choose too model was the Mt. Angel Seminary classroom space. This is a fairly standard class room but has a complex lighting distribution installation bellow the ceiling. The acoustic ceiling tiles are slanted to help distribute light, and the suspended device helps minimize direct light on the occupants and helps distribute the light more evenly. The goal of the project was to find a photograph of the space that illustrates the day lighting properties and then attempt to replicate it the best possible, taking into account material, lighting levels, and scene composition.

Experiment 4: Digital Studio Integration Objective:
Build (and analyze) a carefully crafted schematic design model of a main space for your studio project. If you do not have a current studio project, pick a previous studio project or ask permission to use you Exp. 3 (Master’s space) that you studied physically earlier this semester. This process should help you further explore your design problem if you chose your studio project. If you chose the Master’s space, it will allow for detailed comparison of a well know form. By studying static and dynamic aspects of day lighting with more resolution through Ecotect, Radiance, and Daysim you will round out your skill set for designing quality daylit spaces.
Project Summery: This was a group project consisting of two members. The space that we choose too model and analyze was the Garden City Head Start (Lolly Wyatt Center). This was a three part project where we needed to digitally model the space in sketchup, export it to Ecotect and apply surface material and install a illuminance grid and then export this to Daysim to find both point in time reading (September 21 12:00 pm) and the daylight autonomy (%) of the space. We needed to perform analysis on the current built conditions and then two different iterations on the design.

Experiment 5: Visual Comfort Analysis Objective: Develop a meaningful vocabulary for visual comfort in terms of architectural design while calibrating the vocabulary to scientific metric that can be used to predict visual comfort in your future designs. Project Summery: For this experiment we need to choose two spaces, one that we felt was well daylit and the other not so well. Once we found our space we needed to photo document them using High Dynamic Range (HDR) photography. Processing them in either photosphere or similar photoHdevelopment software. igh Dynamic Range photography Visual Comfort Analysis

Once we found our two spaces and photographically documented them we needed to conduct a Building Experience Survey for the spaces: It is interesting to see the quality of the space as we experience it and how it actually is. Glare and creep became more evident once we were out of the space and analyzing them amongst each other.
Experiment 6: Final Digital Studio Integration Objective: Build and analyze a carefully crafted 100% schematic design model of a main space for your studio project. If you do not have a current studio project see blow. This process should help you further explore and document your design in the case of your studio project. By studying static and dynamic aspects of day lighting with more resolution through Ecotect, Radiance, and Daysim you will round out your skill set for designing quality daylit spaces. This is your chance to make high quality renderings with detailed material definitions to bolster your studio presentation and portfolio.
Flying M Coffee 500 West Idaho Street Boise, ID In calculating the different daylight factors and daylight In autonomy it was difficult to establish the file format to work with all the different software. Once the file structure was established and accurate it was a smooth process to move from Sketchup, Ecotect, Radiance, and Daysim. Physical models allow for fast manipulation of space but once the format is correct a digital model can allow just as much flexibility.
