Land application of domestic wastewater effluent by rapid rate infiltration (i.e., percolation ponds) is a very successful and cost-effective method for wastewater management. Municipal percolation pond systems have been successfully operated in the United States for about 100 years. The disposal concept depends on a relatively high rate of secondary wastewater effluent infiltration into the soil by rapid percolation, either vertically or horizontally, away from the application surface area. This study was accomplished to determine infiltration rates at two working percolation pond systems and the variability of these rates, to compare the operating results with the initial design, and to create a stochastic computer based simulation program for design and operation. The initial study site was located west of Orlando, Florida, and consisted of a system of two percolation ponds. Daily readings were obtained on evaporation, rainfall, flow to the ponds, pond depth and groundwater table elevations. A mass balance inventory equation was formulated and the infiltration parameter was determined. A frequency distribution was created for the rainfall, evaporation and calculated infiltration from the initial site, and then a stochastic computer based simulation program was written with this data. The program calculated results which compared favorably with the design for this initial percolation pond site. A second site was chosen, also located in the Orlando area, to confirm the usefulness of the program and its operational capabilities.

Based on the research of university Student centers and students’ daily activities within a campus, this Thesis focuses on how to strengthen the relationship between the student and the Student Center, by developing a methodology for a successful architecture that towards making the daily life of a student better. This approach will help overcome current disconnectbetween students’ daily activities and an environmentally integrated experience. The Thesis project focus will be the UMass Amherst’s Student Union. The existing Student Union has long been unable to meet the needs of today’s students, and its shortcomings have been felt throughout the campus, from a sense of alienation to the absence of places for activities and for actively connecting the campus with the environment. Methods: Studying two student centers through visiting and investigating. Studying campus life through observing and recording; Using Questionnaire to collect data; studyingthe interaction between campus and facilities. Using Ecotect and concerned software to build and analyze solar radiation, shading and wind.

The project explores alternative strategies to demolition, with the purpose of minimizing waste and optimizing resources in new building projects. The study focuses on the Stockholm suburb of Mariehäll, a former industrial area currently undergoing significant transformation to a mixed-use city. Due to this conversion, wasteful demolitions of large postwar building complexes are prevalent in the area, highlighting the need for sustainable architectural interventions. By examining a set of buildings that are at risk of demolition, the aim of the study was to find a potential host for a new primary school. Among these buildings, a former workshop and warehouse building from the 1950s was identified as the most viable candidate. Through an exploration of reuse and upcycling options, design strategies are proposed for transforming the building into a functional school. By showcasing and analyzing different approaches to the reuse of architectural elements, the study presents methodologies that may be generalized and employed in other projects.

The transformation of Fiskartorpet into an Outdoor Sports Hub is a project aimed at revitalizing the area, promoting active lifestyles, and engaging the community. The existing building, with its rich history and architectural character, is being optimized to cater to the needs of outdoor sports enthusiasts. The tower is being renovated to accommodate jumping platforms on each floor, while a diving pool is added adjacent to it, creating a seamless integration between water-based sports and jumping disciplines. The existing ski jump is transformed into a multi-purpose slope, allowing for up-hill running during summer months. Inside the building, amenities such as a mountain bike rental and repair shop, reception area, offices, changing rooms, and workout rooms are incorporated to enhance the visitor experience. The project takes an approach that respects the building's heritage while introducing elements that symbolize its evolution. By restoring architectural details and façade components and selecting materials that harmonize with the existing structure, a balance is struck between nostalgia and the needs of the modern era. Glazed tiles in dark green, blue, and burgundy are strategically used for their durability and water-resistant properties, adding both functionality and visual cohesion to the design. Overall, the project aims to create a vibrant and functional space that promotes physical activity, community engagement, and easy accessibility to outdoor sports in the heart of Stockholm. It represents an opportunity to revitalize the area, foster social interaction, and contribute to community revitalization through the transformation of a private building into a public space for outdoor enthusiasts.
