The study aims to reduce energy consumption in apartment buildings where individual metering and charging of heat is applied. The aim is to develop planning and design for individual metering and charging in apartment buildings.The study is based on literature review, interviews and case study that include analysis of existing documents. Interviews were carried out with the property developer and the involved consultants who planned the apartment building Yasuragi. To investigate the differences the condominium association has noted in heat consumption between flats, the debit values of the heat were used to discern which houses that were furthest from the average consumption. On these flats there were temperature measurements and thermal photo shoots made for discriminating behavior and possible construction techniques which could be the explanation for the heat spread.Boverket shows that the consumption of heat can be reduced by 10-20% after insertion of individual metering and charging in an apartment block. Heat spread is a problem with individual metering and charging of heat. The spread of heat consumption in Yasuragi depends on heat hikes, transmission losses, external heat sources, thermal bridges and the user’s behavior. The consultant does not plan and design in the current situation to ensure that all flats will be fully equal with respect to external heat sources. They work to make the best possible plan solutions and to make room for all the systems and to get the systems to work. Since the property developer has no requirements or take initiative on IMD-system to the apartments to be equivalent, there are development opportunities in the current situation.The thesis has reported deficiencies in the design stage and provides improvement suggestions to the actors projecting apartment buildings where the IMD applies. It can also be regarded as a knowledge base for developers. To develop the planning stage, the developer and consultants should have experience and better knowledge of how the system is affected by various factors, as well as the design gets to impact upon the final heat consumption. The property developer may require the consultants that they should describe and take into account that each apartment will function equally.Further studies are recommended to investigate whether it is better to build apartment buildings in wooden frames where the individual metering and charging will be applied to reduce the appearance of heat hikes between apartments. The condominium association could through a survey chart the behavior of the residents of the housing.
