Climate change, driven by greenhouse gas emissions, is a growing global concern,
threatening world-wide environment, health and economy. Energy needs for buildings are a …

Horizontal ground heat exchanger (HGHE) is a cost effective method to exploit geothermal
energy due to its shallow installation depth, which meanwhile causes its performance …

A horizontal ground heat exchanger installation is less expensive than a vertical ground
heat exchanger, but more land is required. The system's required pipe length and land area …

Geothermal heat pump (GHP) systems have recently gained popularity in providing heat to
buildings. In this study, the short-term and long-term performance of closed-loop horizontal …

Abstract Ground Heat Exchangers (GHEs) drilled using Horizontal Directional Drilling (HDD)
technology have been proven to be a cost-efficient way of installing ground source heat …

Thermal environments influence the comfort and energy consumption in subway tunnels
and are mainly controlled by environmental control systems (ECSs). The comprehensive …

A UK case study area containing over 33,000 households has been used to investigate
spatial and temporal conflicts in meeting domestic heat demand through renewable …

Wastewater heat recovery (HR) is one of the renewable energy sources. The associated
harmful environmental, health, and social effects of traditional biomass, fossil fuel, and other …

The thermal performance of a ground heat exchanger (GHE) depends on many parameters,
particularly the relation of the working fluid, pipe diameter, and fluid velocity. The effect of …

The problem of heat recovery from sewage effluents is considered. It is shown that the
existing technical solutions to this problem are not reliable enough, because in most cases …
