Energy consumption in residential buildings is one of the major sources of greenhouse gas (GHG) emissions in the U.S. Most of the efforts to minimize these emissions contemplate on construction of new high performance green buildings rather than retrofitting the existing residential building stock, which has the greatest emission reduction potential. In this paper, rapidly increasing GHG emissi...

Hybrid photovoltaic-thermal heat pump (PV/T-HP) solar energy systems are promising since they can achieve a system total efficiency greater than 80%. By maximizing the output of PV/T for simultaneous heating and cooling, this strategy meet over 60% urban households’ needs around 40% their cooling needs. In work, novel evaporator was designed, fabricated, an aluminium foil encapsulated hydrated ...
