MODERNISING OLDER HOUSES TO PASSIVE HOUSE STANDARD


This paper is intended to outline technical solutions for future modernisation of
older buildings by the addition of heat pumps for homes and small businesses, using the
example of an apartment building in Hanover. The apartment building underwent a thorough
energy overhaul including replacing the old decentralised coal/oil/gas/electricity heating
systems with a central heating system plus two groundwater heat pumps.
Brief design guidelines for use of the heat pumps in old buildings will then be outlined.
