GEOFIT: Stakeholders and Markets, a Commercial Approach

The stakeholders in a building retrofit project often are unfamiliar with shallow geothermal energy (SGE) technology and potentially have conflicting requirements [MUSE, 2019]. The following table shows the influence and interest of (in)directly involved stakeholders of typical SGE for building retrofit projects, in the framework of suggested management principles. Building

Low Temperature Heating and High Temperature Cooling

Article by  Henrikki Pieskä (KTH) and Qian Wang (Uponor) A heat emission system is an integral part of a building’s HVAC-system. Heat emission system is the interface between the heat source and the building user, so a proper design is essential both for energy efficiency and user comfort. The objective
