This interactive workshop uses the metaphor of a baseball team to illustrate the variety of people-roles involved in making educational improvements happen, as well as the academic ecosystem in which these changes occur. When making smaller-scale changes, the members may be more loosely structured like an informal sandlot team, though core roles still need to be fulfilled. Larger-scale changes may...
The main negative factors of urbanization are both, environmental problems (pollution of the urban environment, increase of building density, decrease of the green area, etc.), and the destructive influence of the big city on human health (emotional discomfort and stress among inhabitants, mental overloads leading people to alienation from the urban environment, etc.). In the article a new hybrid...
This paper aims to propose an innovative local energy market to accommodate localized energy trading and exchange for communities, buildings and campuses, which may own the surplus local energy produced by distributed energy resources (DER). These energy entities can participate in or form a localized trading platform, either buying or selling energy with searching local partners, without necessarily...
Energy optimisation techniques can be suitably applied to support energy efficiency lighting retrofits in buildings. In previous studies, optimal measurement and verification (M&V) plans are developed to quantify energy savings realised by implementing large-scale lighting retrofit projects. In addition, optimal maintenance plans for the implemented energy efficiency lighting systems are also...
The paradigm shift in construction cost estimation is attributed to technological innovations in the spheres of building information modelling (BIM) and industrialised building systems (IBS). Majority of construction projects experience cost overruns which affect project objectives. The outcome of cost overruns invariably leads to disputes and further delays. Similarly, cost estimators resistance...
In building software systems, the integration of tools with the purpose of exchanging data (i.e. tool interoperability) is common practice. Such an integration is one of the application scenarios of Model-Driven Engineering (MDE), which is often called Model-Driven Interoperability (MDI). In the last few years, some MDI approaches have been presented, and they have shown how MDE techniques are useful...
Direct current (DC) power distribution has recently gained traction in buildings research due to the proliferation of on-site electricity generation and battery storage and an increasing prevalence of end uses operating internally on DC. The research discussed in this paper uses Modelica-based simulation to compare the efficiency of DC building power distribution with an equivalent alternating current...
A service ecosystem, consisting of various kinds of services and mashups, evolves over time. Existing works on the evolution of service systems focus on either evaluating the impacts of services' changes on the usage of services and the stability of the whole ecosystem, or discovering co-occurrences between services, but fail to disclose any knowledge about the evolution of service composition patterns...
Concepts of Control Systems are important as they are present in the operation of a broad set of systems in all engineering branches. Sustainability issues have led to an intensive use of these concepts on systems. However teaching / learning of Control Systems Engineering has always been a difficult subject not only for the underlying theoretical part, but also for the few examples that are traditionally...
Job accessibility is an important factor of urban transition as it influences the residential location choices made by inhabitants and the location of new residential development projects by developers. Spatial interaction models allow for the assessment of the urban transition potential of localities based on the accessibility of various urban activities. In this way they provide valuable information...
The issue of diminishing global energy resources has been of significant concern in recent years. One of the most energy hungry components is the Air-Conditioning and Mechanical Ventilation (ACMV) Systems for buildings, which consumes more than 40% of the total building energy consumed on average. Since people are spending more time staying indoor, the indoor environmental conditions have to be taken...
In this paper, the HVAC System for the S.J. Carew Building at Memorial University is modeled using a state space multi-input and multi-output system (MIMO) approach for analyses and control system design. The IDA Indoor Climate and Energy ICE simulation program is used to develop the models. The system has three air-handling units and four floors. Supply air flow temperature and hot water temperature...
Recent advances in sensor technologies and instrumentation have led to an extraordinary growth of data sources and streaming applications. A wide variety of devices, from smart phones to dedicated sensors, have the capability of collecting and streaming data at unprecedented rates. Typical applications include smart cities & built environments for instance, where sensor-based infrastructures continue...
Context-based modeling of 3D urban terrain has become increasingly popular in the last two decades. Typically, orthophotos are used for texturing ground. In order to increase locational awareness, it is useful to eliminate from the orthophotos those object instances which frequently appear and disappear in the terrain. Vehicles are good examples of such instances. Assuming that vehicles were detected...
In this study we will describe an intervention decision-support method related to residential buildings, which is modelling the condition of buildings based on linguistic expert opinions so that it is capable of taking into consideration the uncertainties included in the expert opinions. Fuzzy signature-based model is used, wherein the uncertainties are integrated into the system by applying interval...
This article describes the main considerations when designing a feedback platform for encouraging end users on adopting more efficient consumption behaviors. A review on behavioral models and the main characteristics of current feedback systems is performed, being completed with a description of an experimental case on 472 households in Portugal to which a feedback platform has been developed to raise...
This paper showcases the use of Bayesian models for real-time strategy (RTS) games AI in three distinct core components: micromanagement (units control), tactics (army moves and positions), and strategy (economy, technology, production, army types). The strength of having end-to-end probabilistic models is that distributions on specific variables can be used to interconnect different models at different...
In present analyses of the architectural constructions, the important place belongs to algorithmic determination of their shapes in masonry structures cross-vaults, which often require expensive restoration. Particularly interesting is the way these buildings lighting by daylight. Daylight, besides the aesthetic and visual effect, has an important role in minimizing the consumption of energy. For...
We presented a multi-scale model, by coupling of three different component models: individual based model (IBM), spatial moment-based model (SMBM) and equation-based model (EBM), for studying of spreading of infectious disease in a 3D office building. We proposed an up-scaling methodology to derive a SMBM from a given IBM, and to generate an EBM from the SMBM. Our results showed that the multi-scale...
Information-communication technology (ICT) of 21st century has become a very powerful tool in all industrial segments in Slovakia, including construction. The development of ICT creates the potential for the application of more sophisticated systems also in the preparation and realization of construction through the using mixed reality. Mixed reality is the field of computer research dealing with...
