Residence
A rainwater collection and storage system is investigated, focusing on water quality at various points: from roof runoff to an underground concrete cistern. A prototype sand filtration system (designed to improve water quality) is built and then tested. The result is complete removal of suspended solids. Design applications for filtration placement are suggested for residential scale housing. Joshua Cohen, Angie Matt |

Retail Store
ABSTRACT: Color is one of the key factors that affect people's choice food and lighting design in supermarkets and grocery stores plays a very important role in making food attractive to customers. There is, however, no single strategy used to make food "look" good. In some supermarkets, they use fluorescent lamps to illuminate vegetables while others use MR-16's lamps to light the same item. Under different lighting conditions, a tomato in one store may look fresher and more delicious than it does in another store. Lighting seriously shapes our perception of food. With the lighting techniques we have learned from ECS, we examined how different lamps affect a person's perception of food. We want to find out the best match of food and light. With this information, you may think twice about what lamps you have in your kitchen and dining room. A simple change to your lamps may make your food look better! Birch Lu, Anita Washko, Ann Wu |

Apartments
ABSTRACT: In order to test the human experience of sound transmission in multi-family housing, we distributed a survey to all of the residents of the Spencer View apartments. This survey was structured to provide data for comparison between impact and airborne sound sources, and the different experiences between the upstairs and downstairs units. We correlated this subjective data against calculations of the acoustic performance of the existing floor assembly. Through the calculations, we found that the apartments are constructed so that they probably meet code minimally. However, the survey data that we received back shows a high level of awareness of and annoyance by sounds passing through the floor assembly between apartments. Most striking (no pun intended) was the degree to which people living downstairs heard impact sounds from upstairs. In this regard, the experience of the upstairs and downstairs apartments were far from similar. This exploration of acoustic isolation in multi-family housing provides the opportunity to study the tenants' perceived degree of contentment towards the acoustic environment. Joshua

Library
The goal of our case study is to evaluate the usability of the fourth floor reading area in the Knight Library (University of Oregon). Because of recent energy conservation measures, 562 lamps have been turned off in order to conserve electricity. Although the lighting is adequate during daylight hours, the reduction of available light in the evening makes much of the space unusable without the electric light. To test our hypothesis, we distributed surveys and conducted our own qualitative and quantitative measurements within the space. Our findings indicate that there was more more than adequate light during the day and inadequate lighting at night. Ben Carlson, Michael Sawiel |
