TL;DR: In this paper, a methodology of sensitivity analysis is presented and an application example is given for design of an office building in Denmark, where the sensitivity analyses will typically be performed at a reasonably early stage of the building design process, where it is still possible to influence the most important design parameters.
Abstract: Building performance can be expressed by different indicators such as primary energy use, environmental load and/or the indoor environmental quality and a building performance simulation can provide the decision maker with a quantitative measure of the extent to which an integrated design solution satisfies the design objectives and criteria. In the design of sustainable buildings, it is beneficial to identify the most important design parameters in order to more efficiently develop alternative design solutions or reach optimized design solutions. Sensitivity analyses make it possible to identify the most important parameters in relation to building performance and to focus design and optimization of sustainable buildings on these fewer, but most important parameters. The sensitivity analyses will typically be performed at a reasonably early stage of the building design process, where it is still possible to influence the most important design parameters. A methodology of sensitivity analysis is presented and an application example is given for design of an office building in Denmark.

TL;DR: In this paper, the authors examined the existing literature in the analysis of life cycle costs of utility-scale electricity storage systems, providing an updated database for the cost elements (capital costs, operational and maintenance costs, and replacement costs).
Abstract: Large-scale deployment of intermittent renewable energy (namely wind energy and solar PV) may entail new challenges in power systems and more volatility in power prices in liberalized electricity markets. Energy storage can diminish this imbalance, relieving the grid congestion, and promoting distributed generation. The economic implications of grid-scale electrical energy storage technologies are however obscure for the experts, power grid operators, regulators, and power producers. A meticulous techno-economic or cost-benefit analysis of electricity storage systems requires consistent, updated cost data and a holistic cost analysis framework. To this end, this study critically examines the existing literature in the analysis of life cycle costs of utility-scale electricity storage systems, providing an updated database for the cost elements (capital costs, operational and maintenance costs, and replacement costs). Moreover, life cycle costs and levelized cost of electricity delivered by electrical energy storage is analyzed, employing Monte Carlo method to consider uncertainties. The examined energy storage technologies include pumped hydropower storage, compressed air energy storage (CAES), flywheel, electrochemical batteries (e.g. lead–acid, NaS, Li-ion, and Ni–Cd), flow batteries (e.g. vanadium-redox), superconducting magnetic energy storage, supercapacitors, and hydrogen energy storage (power to gas technologies). The results illustrate the economy of different storage systems for three main applications: bulk energy storage, T&D support services, and frequency regulation.

TL;DR: Shove as discussed by the authors investigated the evolution of these changes, as well as the social meaning of the practices themselves, concluding that routine consumption is controlled by conceptions of normality and profoundly shaped by cultural and economic forces, and that habits are not just changing, but are changing in ways that imply escalating and standardizing patterns of consumption.
Abstract: Over the past few generations, expectations of comfort, cleanliness and convenience have altered radically, but these dramatic changes have largely gone unnoticed. This intriguing book brings together the sociology of consumption and technology to investigate the evolution of these changes, as well the social meaning of the practices themselves. Homes, offices, domestic appliances and clothes play a crucial role in our lives, but not many of us question exactly how and why we perform so many daily rituals associated with them. Showers, heating, air-conditioning and clothes washing are simply accepted as part of our normal, everyday lives, but clearly this was not always the case. When did the daily shower become de rigueur? What effect has air conditioning had on the siesta at one time an integral part of Mediterranean life and culture? This book interrogates the meaning and supposed normality of these practices and draws disturbing conclusions. There is clear evidence supporting the view that routine consumption is controlled by conceptions of normality and profoundly shaped by cultural and economic forces. Shove maintains that habits are not just changing, but are changing in ways that imply escalating and standardizing patterns of consumption. This shrewd and engrossing analysis shows just how far the social meanings and practices of comfort, cleanliness and convenience have eluded us.
