Purpose – The objective of this study is to highlight the questions arising in the design of district heating and … cooling systems (DHCSs) in a distributed generation context and to present a model to help find cost‐effective solutions … decentralized DHCSs design is developed and applied to two real case studies. Findings – Distributed cooling generation partly …

and historic structure, including internal insulation, a ground source heat pump with underfloor heating, sunspaces and …

Purpose – Water heating is one of the major energy‐consuming operations in the lodging sector. The purpose of the … water systems. Design/methodology/approach – A total of 24 hotels, which use heat pumps as their main water heating systems …, were investigated. A tailor‐made model for estimating the energy requirement of the water heating system was employed …
