Abstract
Energy retrofit of the existing building stock is needed
at higher rate compared to today, if the European
Commission's 20-20-20 goals are to be realized. Economic
arguments are not exclusive drivers of the retrofit
choices of the privately owned buildings. However, it is
certainly important to identify the cheapest solutions to
achieve highest CO2 reduction impact, in order to find
the most effective ways to improve the existing
buildings. Cost effectiveness is an important priority,
since it allows more to be achieved with the same
monetary resource. For a given building typology, located
in a certain economic environment, it is far from trivial
to choose the most cost effective technologies for
renovation. It may be that the cheapest solutions based
on immediate cost are readily identified by the
stakeholders, but once life time costing is brought into
the picture the long term efficiency is much harder to
asses. In this paper the cost effectiveness of several
renovation packages is assessed in relationship with the
multi-family prefabricated concrete buildings, which
occur widely in the building stock in Romania. The
results show several of the building envelope's retrofit
solutions to be cost effective in mitigating CO2
emissions in these buildings. It is also found that
changing the heating method from the currently
predominant district heating to more decentralized
systems can also lead to both important cost savings and
CO2 emission reductions, in particular if heat pumps are
used.
