This report presents an overview of the most important issues which building managers, owners, and HVAC engineers should consider when shifting from natural gas to other (preferably RES) energy generators.
This report describes these issues from a general point of view which is applicable in various climatic conditions and for different heating sources (including those currently under development) for heating, DHW, or other purposes. Strong emphasis is placed on energy efficiency of existing HVAC systems and retrofit measures that will be conducive to the easy transition to carbon neutral buildings in the future, if not already the case.
