TL;DR: In this paper, the authors identify behavioral questions that arise with four kinds of policy interventions for energy efficiency in buildings: information, incentives, standards, and technological research and development, and a general strategy is described for answering such questions by using 6 analytical methods: formal models, analysis of existing data, surveys, ethnographic methods, small-scale experimentation, and evaluation research.

TL;DR: In this article, the statistical performance of four correlations for estimating the monthly average daily horizontal global radiation was evaluated for 140 locations around the world with varied meteorological conditions and geographical locations.

TL;DR: In this article, the authors investigated wind-tunnel tests in a boundary-layer wind tunnel designed to model atmospheric surface layer winds and revealed that the reduction in mean wind load on heliostats in operational positions within the field could be related to the area of upwind blockage of heliastats and fences.

TL;DR: The present investigation deals with the yield of biogas in anaerobic digestion of marine algae at room temperature, which has the potential of supplying a significant portion of the current demand for natural gas, especially in coastal areas.

TL;DR: In this article, the authors present estimates for the direct public-health damages of electricity generation with coal and nuclear power with overlapping uncertainties, with no clear basis for preferring either of these energy sources over the other on these grounds.

TL;DR: In this paper, the authors performed a laboratory study using concentrated solar radiation to destroy hazardous organic wastes and found that high-temperature destruction efficiencies (DE) for the test compounds, exposed to 57 suns of radiant flux, were consistently greater than the DE observed under non-irradiative conditions.

TL;DR: In this paper, the authors examined the temporal pattern and effect of heating degree days, price of natural gas, residual fuel oil, and industrial activity on industrial demand for natural gas between January 1980 and March 1984.

TL;DR: In this paper, three commercial catalysts were used to improve the kinetics of the reaction and it was shown that a cobalt-molybdenum catalyst has the highest activity.

TL;DR: In this paper, a two-stage point-focus solar thermal concentrator with a non-imaging compound paraboloid secondary was designed and tested at the Advanced Components Test Facility (ACTF) operated by the Georgia Tech Research Institute.

TL;DR: A fuzzy set approach to multicriteria modelling is presented for selecting the best alternative solution to a large-scale engineering project and the problems of making expert recommendations, amidst conflicting views of different people and institutions are handled.

TL;DR: In this paper, the authors evaluated long-term wind speed measurements from 117 stations in Turkey in order to find prospective sites for building large scale wind power machines, based on these measurements, monthly mean isopleth maps as well as an annual mean density map for wind speed have been produced.

TL;DR: In this article, a line-focus holographic concentrator model was built for demonstration purposes, where a monochromator coupled with a computer was used to obtain the profile information of each of the holograms in the stack.

TL;DR: In this paper, the diminishing importance of basic materials use in the economies of mature industrial societies, the emerging shift of production based on virgin materials to developing and resource-rich countries, and the increased recycling of materials.

TL;DR: In this paper, the authors proposed the use of thermal barrier coatings before the monolithic ceramics in an adiabatic diesel engine with its higher thermal efficiency and multifuel capability.

TL;DR: In this paper, a second-law analysis of a two-dimensional, fixed-bed regenerator is presented, where the authors assume that the solid matrix has infinite thermal resistance in the flow direction and finite thermal resistance, characterized by the matrix Biot number, perpendicular to the flow flow direction.

TL;DR: In this paper, a simulation model for variable speed heat pumps is described and representative results are presented, where an executive program manages the input and output of data and coordinates the numerical simulation procedure.
