Energy use in buildings and design requirements. The energy costs and financial costs of building materials, structures and space heating, the detailed patterns of use of heating systems in dwellings, and their interactions: their implications for design.
The primary energy costs of building materials and structures are discussed and comparisons are made between typical dwelling types. The economics of alternative wall, roof and floor constructions, providing various levels of insulationy are examined. Costs are assessed for a number of periods from …

A model personal energy meter
… day each of us consumes a significant amount of energy, both directly through transport, heating and use of appliances, and indirectly from our needs for the production of food, manufacture of goods and provision of services. This dissertation investigates a personal energy meter which can record …

Optimizing a start-stop system to minimize fuel consumption using machine learning
… However, these systems introduce additional energy costs, which are associated with the engine restarting. These energy costs must be balanced by the system. In this thesis I describe my work with Ford to improve the performance of their start-stop controller. In this thesis I discuss …

Joint occupancy: the efficient use of urban land
… of land in large urban centers and increasing energy costs have prompted the revival of an old method of construction. Joint occupancy is the sharing of land for different combinations of uses. There are many concerns in our cities where land costs are exorbitant and many users compete for the …

Desalination of brackish groundwater in the United States : minimum energy requirements
… no national assessment has been conducted on the energy costs required to make brackish groundwater potable. Because the ionic composition of groundwater varies significantly from location to location, unlike seawater, conducting site-specific analyses of the resource across the U.S. is necessary. …

Netswap: Network-based Swapping for Server-Embedded Board Clusters
Capital equipment costs and energy costs are the major cost drivers in datacenters. Prior works have explored various techniques, like efficient scheduling algorithms and advanced power management techniques, to maximize resource utilization to reduce the capital and energy costs. The project HEXO …

Profitable thermal renovation of hotels to combat climate change and depletion of fossil fuels: the case of Cyprus
Hotel buildings were identified as significant energy consumers. Within the theoretical framework of the thesis it was argued that climate change and increasing energy prices due to depletion of fossil fuels would cause pressure on hotel operations in Cyprus by increasing their cooling loads and …
