A Prediction Method For Overall Economic Value Of Fault Detection And Diagnostic Tools For Rooftop And Split Systems, David Yuill, James Braun

Durham School of Architectural Engineering and Construction: Faculty Publications

Fault detection and diagnostics (FDD) tools for air-conditioning application may perform well or poorly, but it is difficult to characterize this performance in a meaningful way. Some recently proposed evaluation techniques have provided various statistics to characterize FDD performance, but these results can be difficult for a potential adopter of FDD to understand. A new method of characterizing FDD performance by predicting the overall economic value of the FDD tool is proposed in this paper. It is applicable to FDD tools intended for air-cooled unitary airconditioners, such as rooftop units (RTU) and split systems. The method gives an estimated dollar …

Assessing Downstream Stormwater Impacts For Urban Watershed Planning, Johanna Meyer Pavlowsky

Masters Theses

"The urbanization of watersheds has caused debilitating effects to downstream aquatic ecosystems in catchments and streams. The implementation of green infrastructure (GI), such as permeable pavements and bioretention facilities, has been shown to alleviate these effects by both reducing runoff and mitigating pollutants; however, the implements are often not designed with a specific goal of water improvement. This study targets understanding a small, impaired urban watershed, and the benefits green infrastructure may have to provide environmental, social, and economic improvement to the watershed.

Portions of Rolla including much of the S&T campus drain into the impaired urban waterbody Frisco Lake, …

Identification Of Key Performance Tasks To Demonstrate The Benefit Of Introducing The Facilities Manager At An Early Stage In The Building Information Modelling Process On Public Sector Projects In Ireland., Barry Mcauley

Doctoral

Modelling (BIM) governed process was investigated in this thesis. Governments are now seeking a more rewarding methodology in the management and procurement of public sector building assets. This has seen an integrated focus by International Governments on BIM as a partial solution in both managing and procuring public sector building assets. Despite BIM bringing the Facility Manager closer to project conceptualisation, there was still a reluctance and a lack of perceived benefits of having them involved earlier in the design phase. There remains a lack of clear evidence on what improved contribution the Facilities Manager can provide. This thesis provides …

Analog:Digital, The Digital Spine: A 1 X 1 Strategy For Integrating Digital Tools In Foundation Design Studios, Ting Chin, Claudia E. Hernandez Feiks

Publications and Research

Architectural education today needs to foster the inherent conceptual and creative thought processes the profession demands but also knowledge of all of the tools that allow architects to create and produce their work. Over the last 25 years the number of digital tools used in the practice of architecture has increased exponentially. Incorporating these digital tools, together with analog ones still being taught in most undergraduate programs today, is overstretching already overloaded architectural curricula. This leaves us to consider how we maintain the quality of teaching as the quantity of content increases and the amount of time with students remains …

The Storytelling Of Public Spaces: Rhetoric, Community, And Social Change, Lindsay Kathryn Hamilton

Open Access Theses & Dissertations

This Dissertation examines how public art, broadly defined, contributes to the dialogue of public places. It assumes that public places are filled with rhetoric--from commercial, governmental, private, and other sources. This rhetoric is mainly concerned with the public as audience, receivers of information who are then expected to act in certain ways - following the directions of street signs or entering shops when a window display attracts their attention, for example. Public art, particularly community-based art, can be used to make public places more democratic, providing platforms for people and communities to talk back and reassert their identities. The case …

Normalized Effect Of Condenser Fouling And Refrigerant Charge On Performance Of Vapor Compression Air Conditioning Systems, Mehdi Mehrabi, David Yuill

Durham School of Architectural Engineering and Construction: Faculty Publications

Several laboratory experiments have studied the effect of faults on vapor compression cycle air-conditioning systems. There has been a particular focus on refrigerant charge variation, which is believed to be quite common in air conditioners, and a lesser focus on heat exchanger fouling. The majority of the published results evaluate the fault effects on particular system operating parameters in one unit. For example, the effect on capacity and efficiency are typically evaluated. The results differ from one study to the next. The current paper summarizes the effects for all of the results available in the literature for condenser fouling and …

A Thermo-Activated Wall For Load Reduction And Supplementary Cooling With Free To Low-Cost Thermal Water, Yuebin Yu, Fuxin Niu, Heinz-Axel Guo, Denchai Woradechjumroen

Durham School of Architectural Engineering and Construction: Faculty Publications

A building envelope serves as a thermal barrier and plays an important role in determining the amount of energy used to achieve a comfortable indoor environment. Conventionally, it is constructed and treated as a passive component in a building thermal energy system. In this article, a novel, mini-tube capillary-network embedded and thermal-water activated building envelope is proposed to turn the passive component into active, therefore broaden the direct utilization of low-grade thermal energy in buildings. With this proposed approach, low-grade thermal water at a medium temperature close to the ambient environment can be potentially utilized to either counterbalance the thermal …

Durham School of Architectural Engineering and Construction: Faculty Publications

Upper room ultraviolet germicidal irradiance (UVGI) has been shown to reduce the concentration of bioaerosols in controlled chambers. However, there is a lack of experimental results on the reduction of bioaerosol concentrations by UVGI devices in actual uncontrolled buildings. This study was carried out in an American elementary school in the Midwest. Two sampling procedures were carried out in six selected classrooms with similar dimensions that were separated into two groups: (1) UVGI exposure group and (2) non-UVGI control group. Two-stage Tisch culturable impactors were utilized to collect airborne culturable bacteria and fungi. Monthly samples were collected during unoccupied period …

The Importance Of Passive Sustainable Design, Caitlin Raymond

Williams Honors College, Honors Research Projects

Sustainability is a topic regularly discussed within today’s culture. Many people are worried about society’s future due to pollution, excessive use of nonrenewable resources, and more. Even with all of the growing awareness and promotion, the historical context and more specifically the passive design techniques used in buildings have received little attention. It is imperative to increase this awareness, as well as increase the application of passive sustainable techniques to ensure that sustainable building is efficient and effective. This project has two portions, a literature review and a design project. The literature review assembles research and techniques collected on passive …

An Exploration Of Structural Timber Innovation, Simon Beskitt

Williams Honors College, Honors Research Projects

In many undergraduate programs of study, civil and structural engineering students are exposed to introductory material regarding timber construction. The information received in the undergraduate experience typically consists of a brief summary of the basic mechanical properties of wood but does not significantly cover timber design. Much greater emphasis is placed on design practices involving steel and concrete, likely due to their prominence in contemporary building trends in civil engineering. While it is true that wood is one of the older materials in terms of its utilization in structural and architectural design, it is certainly not an antiquated choice. Wood …

This communication process does not always happen smoothly due to possible barriers during the information flow. The purpose of this study is to understand these potential information flow barriers and to use concept maps to engage students in discussions about communication within the construction industry. Concept map activities performed with industry professionals and senior construction management students in separate phases are described. To complement the concept map findings, interviews with key …

Fault Detection And Diagnosis Process For Oversizing Design On Multiple Packaged Air-Conditioning Units, Denchai Woradechjumroen, Haorong Li, Thanapat Promwattanapakee

Durham School of Architectural Engineering and Construction: Faculty Publications

Heating, ventilation, air-conditioning and Refrigeration (HVAC&R) systems are seldom designed or commissioned properly. The situation leads to abrupt or degradation faults resulting in inefficient energy uses, excessive energy consumption and high service costs. To solve these aforementioned problems, fault detection and diagnosis (FDD) is utilized to firstly detect any abnormal conditions of a system and then diagnoses and determines their causes. In order to apply this concept in HVAC oversizing designs, this paper proposes the state-of-art procedure of a FDD procedure for analyzing the inherently faulty design (oversizing) of multiple packaged air-conditioning units used to supply cooling for an open …
