On The Construction Industry

Abstract
Energy consumption in the building sector accounts for more than one-third of
energy consumption in Austria. Heating energy consumption has been
decreasing due to defined heating energy indicators required by subsidy
schemes, and since 2009 also by the revised building codes, as required by the
EPBD. However, electricity consumption has been rising due to increasing
cooling needs, in non-residential buildings as well as in residential buildings.
Therefore, emphasis is not only necessary to reduce heating energy use, but also
on encouraging sustainable methods of ensuring summer comfort, for example
through facilitating integrated design. This brings architects and energy
engineers together in the early planning stage to limit overheating in summer by
architectural design, passive measures, and solar cooling. To promote this
development, the Austrian klima:aktiv building standard has been developed.
The standard sets requirements to be met for heating and cooling needs, user
comfort, ecological construction materials, and material use. Buildings meeting
all the requirements are awarded the klima:aktiv label, and in addition they meet
the basic requirements to achieve the even more ambitious building certificate
according to TQB (the Austrian national sustainable building certification
scheme). The combined step-wise model was chosen to lower the barriers for
companies to become familiar with environmentally conscious construction. This
contribution provides an overview of the Austrian building sector and the policy
instruments applied to decrease energy consumption for heating and cooling. It
points out the implications on the construction sector by describing case study
buildings with excellent environmental performance.
