Application The GHD energy consumption model calculates the energy consumption and greenhouse gas emissions of the commercial, trade, and services industries, by sector. Based on this, necessary investments (new and replacement investments) and energy costs are derived. The model can be used to simulate, compare, and evaluate possible decarbonisation paths. In addition, it can be used to calculate the effect of energy and climate policy instruments. Model core The Prognos GHD model calculates the energy consumption and related GHG emissions of the commercial, trade, and services sector by application and energy source, in annual increments. It is a long-term, bottom-up simulation model. Central applications include space heating, hot water, process heat, mechanical energy, refrigeration, lighting, ICT, and process cooling. The energy consumption of the applications is calculated in the smallest proportion possible according to clearly defined categories. The focus is on the detailed mapping of the sectors, the area used, and plant efficiencies. The usable area is differentiated according to the age of construction, building type, energy sources, and renovation status. In contrast, applications are differentiated according to their system types, their efficiency and their structure.
