Furthermore, understanding the heating alternatives from perspectives of their efficiency, environmental standards, lifetime and life cycle costs, levelized costs of heat provided as well as from the perspective of market availability for both technologies and accompanying services is a critical pre-requisite for the accelerated adoption of modern standards. From the public perspective, it is also critical to understand the implications of massive changeout schemes on employment, security and affordability of energy supply, current account balances and foreign trade balances. A user perspective is also required, and the fitness of different technologies should also be viewed from the socio-demographic perspective of the region as a whole taking into account differences between individual contracting parties where relevant. Understanding the building conditions and viewing the technologies from the perspective of building stock is another important factor to understand when making individual or collective decisions on the substitution of the heating device. Finally, superb and informed communication is required to facilitate the consensus-building process and to advocate among relevant national and regional institutions to recognize the needs and necessities as well as sensibility of the energy poverty issue among the vulnerable groups.
