Mind the gap : quantifying principal-agent problems in

Mind the Gap is an unprecedented attempt to quantify the size of one of the most pervasive barriers to energy efficiency - principal-agent problems, or in common parlance, variations on the 'landlord-tenant' problem. In doing so, the book provides energy analysts and economists with unique insights into the amount of energy affected by principal-agent problems.

Rankine cycle - Wikipedia

The Rankine cycle is an idealized thermodynamic cycle describing the process by which certain heat engines, such as steam turbines or reciprocating steam engines, allow mechanical work to be extracted from a fluid as it moves between a heat source and heat sink.The Rankine cycle is named after William John Macquorn Rankine, a Scottish polymath professor at Glasgow University.

Effect of Bed Pressure Drop on Performance of a CFB Boiler

fluidized-bed (CFB) boiler, and (iii) pulverized coal boiler. Of these, CFB boilers are most suitable in terms of combustion efficiency (87% or higher), fuel flexibility, lower pollutant emissions, and economy of operation. All subprojects are designed to either purchase heat from existing CHPs that use CFB technology or supply heat from large

Agent based HVAC optimization model for building energy

Abstract: The Heating, Ventilation and Air Conditioning (HVAC) systems contribute to a considerable percentage (about 50%) of a building's energy consumption. So controlling them will have a significant impact on the energy efficiency of the building, thereby reducing the carbon footprint. The factors that affect the indoor conditions include static factors like the architecture of the
