RE-VALUE: Value Creation by Energy Renovation, Refurbishment and Transformation of the Built Environment – Modelling and Validating of Utility and Architectural Value

Denmark aims for a CO2 neutral society by 2050. This ambitious goal cannot be
obtained without a drastically reduced energy use for construction and operations
of buildings. 75% of the buildings that exist today will still be in operation in 2040.
Hence, a considerable amount of the existing building mass must undergo a
substantial renovation to comply with the ambition. Energy renovation is hence a
societal challenge, which dramatically will affect the built environment. The overall
objective of the RE-VALUE project is to develop and demonstrate the validity of a
generic renovation assessment method. This method will allow client and decision
makers to identify cost-efficient solution in terms of energy performance as well as
create utility and architectural values. The largest potential for energy savings lies
in the re-insulation of the building envelope. The transformation towards a more
energy-efficient building mass will thus dramatically affect the built environment.
Hence, the question of articulating the architectural consequences and derived
potentials of this transformation are an urgent matter if the energy savings are not
to be realized by a uniform technical cladding which devaluates the building. The
RE-VALUE project will incorporate these factors in a model for the future renovation
process, documenting how added value can be obtained. This assessment model
will build on technical solutions, architectural solutions, indoor climate and health
solutions, and sustainable construction process solutions. The output of the model
can be illustrated through a “Renovation Index” documenting how much added
value the client, the users, and society can achieve.
