An Adaptive Utility Interactive Photovoltaic System Based On A Flexible Switch Matrix To Optimize Performance In Real-Time, Mahmoud Alahmad, Mohamed Amer Chaaban, Siu Kit Lau, Jonathan Shi, Jill Neal

Durham School of Architectural Engineering and Construction: Faculty Publications

Reconfigurable architectures are of great interest to system designers to improve the system’s operation and efficiency. In this paper, we propose an adaptive utility interactive photovoltaic (PV) system based on a novel Flexible Switch array Matrix topology. This proposed system maximizes the generated power in real-time in response to operational conditions such as shading, soiling, mismatches, and module failure among others. The proposed system is a compromise in the utilization of power conditioning equipment to maximize energy capture and system efficiency. Simulation results demonstrate an average 13% improvement in efficiency when compared with the central inverter topology performance. A prototype …

Effects Of Roof Pitch On Air Flow And Heating Load Of Sealed And Vented Attics For Gable-Roof Residential Buildings, Shimin Wang, Zhigang Shen

Durham School of Architectural Engineering and Construction: Faculty Publications

Pitch value is an important consideration in residential gable roof design and construction. However, how roof pitch, coupled with air flows in attic space, affects the energy performance of building attics has been barely investigated. In this paper, a 2D unsteady computational fluid dynamics (CFD) model is employed to investigate the effects of roof pitch on air flow and heating load of both sealed and vented attics for gable-roof residential buildings. The simulation results show that air flow in the sealed attics is steady and asymmetric, while that in the vented attics is a combination of an essentially symmetric base …

Effects Of Inclusion Shapes Within Rigid Porous Materials On Acoustic Performance, Hyun Hong, Siu-Kit Lau

Durham School of Architectural Engineering and Construction: Faculty Publications

The present study investigates the influence of various shapes of inclusions having same volume embedded in a porous rigid material. Previous studies showed improvement of the broadband sound absorption with particular shapes of inclusions. However, different volumes of the inclusions have been considered; therefore, the bulk densities are not the same for comparison. The present study extends the investigations of inclusions in porous materials with same volume (or bulk density) to eliminate the influence by the change of bulk density. The effects of shape will be discussed. Finite element modeling will be used for this study. Total four different shapes: …

Impacts Of Ventilation Ratio And Vent Balance On Cooling Load And Air Flow Of Naturally Ventilated Attics, Shimin Wang, Zhigang Shen

Durham School of Architectural Engineering and Construction: Faculty Publications

The impacts of ventilation ratio and vent balance on cooling load and air flow of naturally ventilated attics are studied in this paper using an unsteady computational fluid dynamics (CFD) model. Buoyancy-driven turbulent ventilations in attics of gable-roof residential buildings are simulated for typical summer conditions. Ventilation ratios from 1/400 to 1/25 combined with both balanced and unbalanced vent configurations are investigated. The modeling results show that the air flows in the attics are steady and exhibit a general streamline pattern that is qualitatively insensitive to the variations in ventilation ratio and vent configuration. The predicted temperature fields are characterized …

The Impact Of Roof Pitch And Ceiling Insulation On Cooling Load Of Naturally-Ventilated Attics, Shimin Wang, Zhigang Shen, Linxia Gu

Durham School of Architectural Engineering and Construction: Faculty Publications

A 2D unsteady computational fluid dynamics (CFD) model is employed to simulate buoyancy-driven turbulent ventilation in attics with different pitch values and ceiling insulation levels under summer conditions. The impacts of roof pitch and ceiling insulation on the cooling load of gable-roof residential buildings are investigated based on the simulation of turbulent air flow and natural convection heat transfer in attic spaces with roof pitches from 3/12 to 18/12 combined with ceiling insulation levels from R-1.2 to R-40. The modeling results show that the air flows in the attics are steady and exhibit a general streamline pattern that is qualitatively …

Development And Evaluation Of A Simplified Modeling Approach For Hydraulic Systems, Yuebin Yu, Vivian Loftness, Daihong Yu, Yan Lu, Volker Hartkopf

Durham School of Architectural Engineering and Construction: Faculty Publications

This paper presents how a hydraulic system can be properly modeled for hydraulic balancing, knowledge of flow distribution, coupled simulation, and evaluation of control, etc. It focuses on water-based heating and cooling systems, which generally have high energy efficiency in design but could perform poorly in reality due to the undersensing condition and strong thermal-hydraulic coupling. The study introduces the motivation, presents the simplified modeling methodology, and illustrates the model and simulating structure. A preliminary evaluation of the method is conducted with two simple simulations. The proposed “node-branch-state” modeling approach could be easily modified, expanded and integrated into a detailed …

New Urban Living: High-Rise Vertical Farming In A Mixed Use Building, Boston, Ma, Zachary Silvia

Architecture Theses and Projects

The focus of the project is the combination of vertical farming and living in a structure that provides for itself and the surrounding community. Essentially, the result is communal living through vertical farming. To raise awareness and invite surrounding neighbors and workers into the process, the first four floors are dedicated to social interaction and a display of the systems at use. Along the path from a public market, to a café, and finally to a gathering space, visitors walk along a ramp/display of the aquaponic system.

Nature And Architecture: A Holistic Response, Jarrod Martin

Architecture Theses and Projects

The general functions of the project will be a natural healing center and research facility for natural medicine. As medical practice and theory begin to shift in the understanding on natural treatment, modern medicine facilities are becoming more environmentally friendly. Hospitals are pursuing sustainable practices as well as seeking LEED certification in the United States. Although LEED is not a necessity for this project, the natural healing center will focus on holistic care as the primary medical treatment option for patients while engaging the project in sustainable design.

Lam: Laughing My Architecture Of, Elizabeth Straub

Architecture Theses and Projects

Architecture gives the perfect opportunity to join people together with humor and laughter. Through creating a space for a community of comedians to work together, this project will not only bring joy to those who come to see the acts, but also create a sense of community and home for the comedians who work and perform there.

This architecture should not only fill the needs for the program elements, but also bring a sense of wonderment and creativity to inspire those who are there. Though the building does not need to be a pun or a joke in itself, it …

Architecture Theses and Projects

The Woonasquatucket River Environmental Discovery Center (WREDC) is a place where students of the environment can enjoy a natural space within their own community. It provides a much needed connection to a site which, for far too long has been off limits to the community. As a potential learning environment for young students, the WREDC becomes a platform for a sustainable lifestyle. In this place we learn about the past, connect it to the present, and allow for change in the future.

This thesis is about making these connections of past and future through the current constructs of the Social, …

Advancing The Human Right To Housing In Post-Katrina New Orleans: Discursive Opportunity Structures In Housing And Community Development, Leigh Graham

Publications and Research

In post-Katrina New Orleans, housing and community development (HCD) advocates clashed over the future of public housing. This case study examines the evolution of and limits to a human right to housing frame introduced by one nongovernmental organization (NGO). Ferree’s concept of the discursive opportunity structure and Bourdieu’s social field ground this NGO’s failure to advance a radical economic human rights frame, given its choice of a political inside strategy that opened up for HCD NGOs after Hurricane Katrina. Strategic and ideological differences within the field limited the efficacy of this rights-based frame, which was seen as politically radical and …

Razing Lafitte: Defending Public Housing From A Hostile State, Leigh Graham

Publications and Research

The contentious politics of the demolition of Lafitte public housing in post- Katrina New Orleans and its replacement with mixed-income properties is a telling case of the strategic conflicts housing advocates face in public housing revitalization. It reveals how the qualified outcomes of HOPE VI interact with local institutional and historical circumstances to confound the equity and social justice goals of housing and community development advocates. It shows the limits to public housing revitalization as an urban recovery strategy when hostile government leadership characterizes a region, and the state is recast as an adversary rather than revitalization partner. This case …
