Occupancy driven supervisory control of indoor environment systems to minimise energy consumption of airport terminal building

Mambo, Abdulhameed D. January 2013 (has links)
A very economical way of reducing the operational energy consumed by large commercial buildings such as an airport terminal is the automatic control of its active energy systems. Such control can adjust the indoor environment systems setpoints to satisfy comfort during occupancy or when unoccupied, initiate energy conservation setpoints and if necessary, shut down part of the building systems. Adjusting energy control setpoints manually in large commercial buildings can be a nightmare for facility managers. Incidentally for such buildings, occupancy based control strategies are not achieved through the use of conventional controllers alone. This research, therefore, investigated the potential of using a high-level control system in airport terminal building. The study presents the evolution of a novel fuzzy rule-based supervisory controller, which intelligently establishes comfort setpoints based on flow of passenger through the airport as well as variable external environmental conditions. The inputs to the supervisory controller include: the time schedule of the arriving and departing passenger planes; the expected number of passengers; zone daylight illuminance levels; and external temperature. The outputs from the supervisory controller are the low-level controllers internal setpoint profile for thermal comfort, visual comfort and indoor air quality. Specifically, this thesis makes contribution to knowledge in the following ways: It utilised artificial intelligence to develop a novel fuzzy rule-based, energy-saving supervisory controller that is able to establish acceptable indoor environmental quality for airport terminals based on occupancy schedules and ambient conditions. It presents a unique methodology of designing a supervisory controller using expert knowledge of an airport s indoor environment systems through MATLAB/Simulink platform with the controller s performance evaluated in both MATLAB and EnergyPlus simulation engine. Using energy conservation strategies (setbacks and switch-offs), the pro-posed supervisory control system was shown to be capable of reducing the energy consumed in the Manchester Airport terminal building by up to 40-50% in winter and by 21-27% in summer. It demonstrates that if a 45 minutes passenger processing time is aimed for instead of the 60 minutes standard time suggested by ICAO, energy consumption is significantly reduced (with less carbon emission) in winter particularly. The potential of the fuzzy rule-based supervisory controller to optimise comfort with minimal energy based on variation in occupancy and external conditions was demonstrated through this research. The systematic approach adopted, including the use of artificial intelligence to design supervisory controllers, can be extended to other large buildings which have variable but predictable occupancy patterns.

Phase change thermal enery storage for the thermal control of large thermally lightweight indoor spaces

Gowreesunker, Baboo Lesh Singh January 2013 (has links)
Energy storage using Phase Change Materials (PCMs) offers the advantage of higher heat capacity at specific temperature ranges, compared to single phase storage. Incorporating PCMs in lightweight buildings can therefore improve the thermal mass, and reduce indoor temperature fluctuations and energy demand. Large atrium buildings, such as Airport terminal spaces, are typically thermally lightweight structures, with large open indoor spaces, large glazed envelopes, high ceilings and non-uniform internal heat gains. The Heating, Ventilation and Air-Conditioning (HVAC) systems constitute a major portion of the overall energy demand of such buildings. This study presented a case study of the energy saving potential of three different PCM systems (PCM floor tiles, PCM glazed envelope and a retrofitted PCM-HX system) in an airport terminal space. A quasi-dynamic coupled TRNSYS®-FLUENT® simulation approach was used to evaluate the energy performance of each PCM system in the space. FLUENT® simulated the indoor air-flow and PCM, whilst TRNSYS® simulated the HVAC system. Two novel PCM models were developed in FLUENT® as part of this study. The first model improved the phase change conduction model by accounting for hysteresis and non-linear enthalpy-temperature relationships, and was developed using data from Differential Scanning Calorimetry tests. This model was validated with data obtained in a custom-built test cell with different ambient and internal conditions. The second model analysed the impact of radiation on the phase change behaviour. It was developed using data from spectrophotometry tests, and was validated with data from a custom-built PCM-glazed unit. These developed phase change models were found to improve the prediction errors with respect to conventional models, and together with the enthalpy-porosity model, they were used to simulate the performance of the PCM systems in the airport terminal for different operating conditions. This study generally portrayed the benefits and flexibility of using the coupled simulation approach in evaluating the building performance with PCMs, and showed that employing PCMs in large, open and thermally lightweight spaces can be beneficial, depending on the configuration and mode of operation of the PCM system. The simulation results showed that the relative energy performance of the PCM systems relies mainly on the type and control of the system, the night recharge strategy, the latent heat capacity of the system, and the internal heat gain schedules. Semi-active systems provide more control flexibility and better energy performance than passive systems, and for the case of the airport terminal, the annual energy demands can be reduced when night ventilation of the PCM systems is not employed. The semi-active PCM-HX-8mm configuration without night ventilation, produced the highest annual energy and CO2 emissions savings of 38% and 23%, respectively, relative to a displacement conditioning (DC) system without PCM systems.

Hijacking Generic Space: The Expanded Airport Hub

Barlow, Kelly 05 September 2012 (has links)
This thesis examines the formal and programmatic expansion of one of the most efficient generic spaces, the international airport hub, by serving the specific needs of an increasingly common mobile citizen, the medical tourist. International airport hubs are comprised of a network of interlinked corridors where large transient populations are received, held and then dispersed again. The medical tourist is a product of the rapidly increasing cost and specialization associated with medical treatment procedures. Recognizing that the density of airport hubs now rivals that of contemporary city centers, this project expands the capacity of the international airport hub, thus enabling the airport to compete for citizens in a manner similar to cities. As one iteration of a potential airport expansion system that could serve multiple mobile citizen types, this project exploits the security requirements of an existing airport and an innovative program to hypothesize a new type of airport terminal.

Designing A New Architectural Program: The Norms And Attributes Of Regional Airports / Kutahya-afyonkarahisar-usak

Apaydin, Asli 01 December 2007 (has links) (PDF)
Today&rsquo / s dynamics - the globalization process, economic growth together with late-capitalism, the number of population living in cities and improvements in technology, communication and electronic media - have changed the course of air transportation. As the demand for aviation has increased, the policy of &ldquo / regional air transportation system&rdquo / has begun to be extensive through the world in order to provide an integrated and sustainable air transport system. As for Turkey, together with deregulation of air transportation system in 2003, the government has started the &ldquo / Project of Regional Air Transport&rdquo / . In this respect, some new regional airports are put on the agenda, which required contemporary norms and attributes of regional airport terminals. When regional airport terminals are examined, it is observed that they have typologies, all abstracted from their time-space frameworks. But, today&rsquo / s dynamic architecture attempts to alter this psyche of typology in order to create dynamic and indeterminate spaces in relation to instable transformations in contemporary cities. However, through the restructuring process, in relation to the city context, the static and determinate architecture of regional airport terminal can be challenged. Namely, an architectural program can be utilized as a tool for creating a dynamic architecture. In this respect, by designing a new architectural program for K&uuml / tahya-Afyonkarahisar-USak Regional Airport Terminal, which is on the agenda of the government, this study firstly, examines the norms and attributes of regional airports and secondly investigates how the architectural program of regional airport terminals should be designed according to the needs of contemporary cities in the 21st century.

Although the literature shows these criteria as relevant in airport choice, note a lack of studies relating time and cost as criteria in the choice of cargo airports. In this sense, this study makes an analysis of the process of choosing airports for export of mango, identifying the criteria used, as well as the relationship between the criteria and the impact of the decision based on the prioritization of one criterion over the other. For this, through the AHP – Analytic Hierarchy Process method, indicators related to time and cost were compared, from interviews, performed with Brazilian mango exporters. From the selection criterion pointed out by exporters of mango, was simulated the choice between Brazilian airports most used for export the fruit in recent years. The results show that the prioritization of choice by the time, commonly used as a reference, can result in loss of road freight, increasing a 23% the costs with access to the airport terminal. In this sense, future studies can be conducted with the purpose to verify the relation between cost and time, in the decisions of choice between cargo airports involving nonperishable products. / O tempo e o custo são alguns dos critérios envolvidos nas tomadas de decisões relacionadas ao transporte. Embora a literatura apresente esses critérios como relevantes na escolha de utilização de determinado aeroporto, nota-se carência de estudos relacionando tempo e custo como critérios de seleção entre aeroportos de cargas. Diante do exposto, esse estudo busca analisar o processo de escolha entre aeroportos para exportação de manga, identificando os critérios utilizados, bem como a relação entre eles e o impacto da decisão baseada na priorização de um critério sobre o outro. Assim, através do método Analytic Hierarchy Process – AHP, foram comparados indicadores relacionados ao tempo e ao custo, a partir de entrevistas realizadas com exportadores brasileiros de manga. Com o critério de seleção apontado pelos exportadores de mangas, foi simulado a escolha entre os três aeroportos brasileiros que mais embarcaram a fruta para exportação nos últimos anos. Os resultados mostram que a escolha priorizando o tempo, comumente utilizada como referência, pode resultar em perda de frete rodoviário, acarretando um aumento de até 23% nos custos com acesso ao terminal aeroportuário. Nesse sentido, estudos futuros podem ser conduzidos com o intuito de verificar a relação entre custo e tempo, nas decisões de escolha entre aeroportos de cargas envolvendo produtos não perecíveis.
