We combine a survey and an experiment with real pay-out among Peking University students to measure and validate individual risk attitudes. The experiment involves choosing between a cash payment and playing a lottery. The survey questions ask for the reservation price of a hypothetical lottery...

This paper concerns heat exchange devices with a zigzag configuration containing multi-phase change materials (m-PCMs). A two dimensional mathematical model was established to model the charging behaviour. An experimental system was built to validate the model. The modelling results agree...

A Stirling engine with nominal output power of 1 kW is tested using air and helium as working gases. The influence of working pressure, engine speed and temperature of the hot source is studied, analyzing instantaneous gas pressure as well as instantaneous and stationary temperature at...

The use of photovoltaic (PV) systems has been showing a significant growth trend but for a more effective development of this technology it is essential to have higher energy conversion performances. Producers of PV often declare an higher efficiency respect to real conditions and this deviation...

Thermal bridges are areas of risk of the building envelope, inducing uncontrolled increments of heat transfer, mainly in winter. This notwithstanding, thermal bridges are often neglected in energy audits, since many numerical codes for building energy simulations adopt heat transfer models based...

Predicted climate changes and the increased intensity of urban heat islands, as well as population aging, will increase the energy demand for the cooling of buildings in the future. However, the energy demand for cooling can be efficiently reduced by low-exergy free-cooling systems, which use...

In the present work, the reliability of the “INPUT–OUTPUT” (I/O) method, as a tool for the description of the energetic performance and the prediction of long-term yield of Large Solar Thermal Systems (LSTS) is being investigated. The efficacy of the method over a wide range of conditions,...
