AbstractIn closing his 2008 Myer Lecture, the scientist and environmentalist Dr Tim Flannery said that this century will be defined by the search for sustainability. How perilous therefore that nowadays there is so much overuse of the word “sustainability” that it has become a cliché. Today's tertiary students studying architecture and energy-related subjects are so exposed to this linguistic devaluation that most of them appear to have accepted the vagueness of the term and are on their way to becoming the next generation of misusers. This paper presents a case study of an attempt to sharpen up the debate with some university students from these particular disciplines. A model of the four principles of sustainable development that has been found to be particularly useful is described. The students in question were challenged to think about the meaning of some of the words ascribed to new buildings and about the implications of the four principles to energy supply systems.

Remaining useful life (RUL) is of great importance to energy supply systems, such as battery pack. In this paper, an optimization model of RUL for the paralleled battery pack on expansion mode is proposed based on the basic concept of RUL and the capacity fading model. genetic algorithm (GA) is adopted to solve the problem. Case study shows that the battery pack's RUL can be extended by using the optimization model and GA.

An energy supply system consists of a system of power plants and transmission anddistribution systems that supply electrical energy. The present project is limited to the modellingof the generation system. Its objective is the design and implementation of a web-basedapplication for simulating energy supply systems using the Laravel framework. The projectfocuses on six modules representing geothermal energy, solar energy, biopower, hydropower,storage, and fossil-based energy that are allocated to satisfy a given power demand. It isexecuted as a time series modelling for an exemplary year with hourly resolution. Thedevelopment of the software is divided into four steps, which are the definition of the userrequirements, the system design (activity, use case, system architecture, and ERD), the softwaredevelopment, and the software testing (unit testing, functionality testing, validity testing, anduser acceptance testing). The software is successfully implemented. All the features of thesoftware work as intended. Also, the software goes through validity testing using three differentinput data, to make sure the software is accurate. The result of the testing is 100% accuracy withrespect to the underlying model that was implemented in an excel calculation.

The majority of the single-family houses in Sweden are affected by deteriorations in building envelopes as well as heating, ventilation and air conditioning systems. These dwellings are, therefore, in need of extensive renovation, which provides an excellent opportunity to install renewable energy supply systems to reduce the total energy consumption. The high investment costs of the renewable energy supply systems were previously distinguished as the main barrier in the installation of these systems in Sweden. House-owners should, therefore, compare the profitability of the energy supply systems and select the one, which will allow them to reduce their operational costs. This study analyses the profitability of a ground source heat pump, photovoltaic solar panels and an integrated ground source heat pump with a photovoltaic system, as three energy supply systems for a single-family house in Sweden. The profitability of the supply systems was analysed by calculating the payback period (PBP) and internal rate of return (IRR) for these systems. Three different energy prices, three different interest rates, and two different lifespans were considered when calculating the IRR and PBP. In addition, the profitability of the supply systems was analysed for four Swedish climate zones. The analyses of results show that the ground source heat pump system was the most profitable energy supply system since it provided a short PBP and high IRR in all climate zones when compared with the other energy supply systems. Additionally, results show that increasing the energy price improved the profitability of the supply systems in all climate zones.
