Climate change could significantly affect consumer demand for energy in buildings, as changing temperatures may alter heating and cooling loads. Warming climates could also lead to the increased adoption and use of cooling technologies in buildings. We assess residential electricity and natural gas demand in Los Angeles, California under multiple climate change projections and investigate the p...

Share of generating units from renewable energy sources is constantly increasing and introducing stochastic nature into the system. This results in undesirable fluctuations of mains frequency and thus, a rising need for frequency regulation services. Providing sufficient power reserves presents a complicated task and usually requires special types of fast response power plants running part-load...

The demand for comfort cooling is increasing very quickly around the world, e.g. due to improved living standards. At present, air-conditioning is consuming large amounts of electricity, often during hours of peak power demand. Also, a major part of the electricity around the world is produced from fossil fuels, and thus the threat of global warming, caused by increasing emissions of carbon dio...

this paper describes a study that starts with an analysis of typical energy demand profiles in a hospital setting followed by a case study of a combined cooling, heating, and power (cchp) generation system.cchp is an autonomous system that combines the generation of electrical, heating, and cooling energy.the driving units are two high-efficiency gas engines that produce electrical and heat ene...

This paper provides the first estimates of end-use specific emissions factors, which are estimates of the amount of a pollutant that is emitted when a unit of electricity is generated to meet demand from a specific end-use. In particular, this paper provides estimates of emissions factors for space cooling and heating, which are two of the most significant end-uses. The analysis is based on a n...

The cooling market, in particular air-conditioning, has been growing rapidly in the UK. People now want more comfort and control of their indoor environment. Simultaneously, climate change models predict uncomfortably hot summers towards 2050. This report investigates how comfort levels and climate change will influence the demand for cooling, and policy options to address UK demand that avoid ...

The rheological characteristics of digested sludge are severely temperature dependent. An effect of temperature on rheological properties of digested sludge is partially irreversible. In this paper, the effects of temperature change and thermal history on viscosity of digested sludge were studied using a stress-controlled rheometer which was connected to a temperature controlled water bath. Dig...

The most important necessity for life is water. Shortage of clean & fresh drinking water leads to suffering. This is mainly contributed by generation of sewage waste mixed with the water bodies, due to unplanned urbanization and has largely contributed to the causing severe water pollution. Pollutants discharged in waste waters can be toxic to aquatic life and cause natural waters to be unfit t...
