Benefits and optimisation of district hybrid ground source heat pump systems

Abstract

Buildings consume large amounts of energy, largely to satisfy their heating and cooling needs. Since most of this energy is derived from fossil fuels, buildings are responsible for a significant share of the world’s CO2 emissions. Shallow geothermal energy is a promising sustainable source of energy which can potentially satisfy the thermal requirements of buildings not only economically but also with reduced carbon emissions. For high density urban areas, buildings can be connected to district Hybrid Ground Source Heat Pump (HGSHP) systems for heating and cooling purposes. This study discusses the benefits of district over individual HGSHP systems. A methodology for the optimisation of dist..
