The development of a real-time energy prediction framework in domestic buildings

The construction industry consumed 35% of worldwide energy, with domestic buildings accounting for 22%. Providing a healthy, positive environment in domestic buildings raised energy demand by around 80% in building operations, with thermal comfort accounting for about half of that increase. Furthermore, building energy consumption is 5 to 10 times greater than predictions given during the design phase. The discrepancy between the actual and intended design is called the performance gap. Although the term is widely used in the context of energy performance, it can also be found in indoor environmental parameters such as temperature, relative humidity, air quality, noise, and illumination. This thesis connects building performance simulation to building operational performance, focusing on real-time energy prediction for space heating in an indoor environment of domestic buildings. The work presented in this research is a technical implementation framework for examining the energy consumption of indoor space heating in real-time, focusing on energy-related thermal comfort conditions at the zone level. Unlike building performance simulation tools, The developed framework can be used beyond the design phase to encompass operations and assist in diagnosing and detecting building underperformance or performance discrepancy over time. Focusing on zone level can offer a greater understanding of the thermal state and energy usage of specific individual spaces, which can also assist in identifying performance disparity. Buildings with good indoor environmental quality are objectively assessed using simulation tools. However, the indoor environmental quality, especially thermal comfort, is experienced subjectively, making the building energy and thermal performance evaluation task challenging. The developed framework extends the use of the energy model to the operational stage by predicting thermal and energy performance based on indoor and outdoor environmental parameters. Moreover, using a parametric energy simulation and machine learning approach connected to an IoT sensor system enable users to identify thermal comfort conditions in the indoor environment and the amount of energy consumed for space heating. Finally, the research identified several lessons that can potentially inform and improve the existing domestic buildings, especially winter space heating. Following the framework, an innovative device was developed and validated using an experimental approach that focuses on real-time energy prediction of space heating. In this process, the experimental case studies' thermal comfort conditions and energy consumption were monitored and analysed to identify thermal-energy performance-related issues, also used for validating the proposed real-time energy prediction module

Urban sunspaces : ecology of atria and arcades

Thesis (M.S.)--Massachusetts Institute of Technology, Dept. of Architecture, 1981.MICROFICHE COPY AVAILABLE IN ARCHIVES AND ROTCH.Includes bibliographical references (leaves 160-167).Historically, atria were protected interior patios; well perceived for their climate tempering and spatial amenity to the building; matching a peaceful private outdoor with the yearly climate cycles. Public buildings adopted this in larger scale, and with the ending 18th century, atria and arcades merged to a period of architectural highlights of glass covered interiors in steel and glass. Passages, hotels and public buildings of an emerging industrial society in Europe and Northern States spurred the evolution of the "Great Indoors" as an urban feature. The ecology of these indoors were consciously achieved by passive means of temperature control. With the rise of mechanical conditioning and excessive use of glass at facades by the beginning of this century, atria and arcades disappeared more or less from the architectural vocabulary. The late 1950s though experienced a revival of atria as a commercial amenity in malls, hotels and similar type of public places. These atria, however, were generally mechanical conditioned; just typically being enormous energy wasters. With the growing urge for energy conservation today, new parameters form our buildings. For this, atria and arcades of urban scale and passive control achieve a new validity as energy conscious urban form. As the key to our energy future in buildings lies well in the urban context, whose inventory per se offers already a fair degree of energy efficiency, improvements there would yield greatest rewards compared to current suburban solar sprawl. The re-interpretation of atria and arcades will provide a perfect planning tool for this urban energy conservation. The glass covered indoors will match with urban scale and site restraints and spur urban life for livable norther winter cities. Exploring atria and arcades as climate buffers and interior amenity for snow belt latitudes, this thesis presents an architectural review, and concludes with design patterns for habitable and energy conscious urban indoors.by Joachim W.

Effort reduction and collision avoidance for powered wheelchairs : SCAD assistive mobility system

The new research described in this dissertation created systems and methods to assist wheelchair users and provide them with new realistic and interesting driving opportunities. The work also created and applied novel effort reduction and collision avoidance systems and some new electronic interactive devices. A Scanning Collision Avoidance Device (SCAD) was created that attached to standard powered wheelchairs to help prevent children from driving into things. Initially, mechanical bumpers were used but they made many wheelchairs unwieldy, so a novel system that rotated a single ultra-sonic transducer was created. The SCAD provided wheelchair guidance and assisted with steering. Optical side object detectors were included to cover blind spots and also assist with doorway navigation. A steering lockout mode was also included for training, which stopped the wheelchair from driving towards a detected object. Some drivers did not have sufficient manual dexterity to operate a reverse control. A reverse turn manoeuvring mode was added that applied a sequential reverse and turn function, enabling a driver to escape from a confined situation by operating a single turn control. A new generation of Proportional SCAD was created that operated with proportional control inputs rather than switches and new systems were created to reduce veer, including effort reduction systems. New variable switches were created that provided variable speed control in place of standard digital switches and all that research reduced the number of control actions required by a driver. Finally, some new systems were created to motivate individuals to try new activities. These included a track guided train and an adventure playground that including new interactive systems. The research was initially inspired by the needs of young people at Chailey Heritage, the novel systems provided new and more autonomous driving opportunities for many powered wheelchair users in less structured environments.EThOS - Electronic Theses Online ServiceGBUnited Kingdo
