Since April 2013, Land Salzburg has been supporting online energy accounting via the ZEUS database. The goal is to be able to compare the energy required for space heating and hot water as calculated in the energy performance certificate directly with the actual consumption.

A simulation software or tool is usually based on the process of modelling a real situation with a set of calculations and assists one in understanding complex systems and decision-making. It helps to examine if the situation or condition changes, how the results would differ.
There are a number of simulation tools in Austrian market; here a few of them are introduced.
The Home Energy Check tools are supporting instruments for home owners or tenants to examine the saving potentials of an apartment or a house. Every home is different and a number of assumptions about the home and family living in are usually taken into account to put together the advice in these tools. It’s therefore important to know that these tools don’t replace an energy expert or expert installer before deciding to purchase any new energy saving measure.
The Viennese Werkbundsiedlung, a development of 70 model houses designed by renowned Austrian and international architects like Josef Frank, Adolf Loos, Gerrit Rietveld, Margarete Schütte-Lihotzky and Richard Neutra, was erected from 1931 to 1932.
Airtightness on-site tests provide surprising experiences and reveal how to increase the quality of building construction.
The construction of buildings with very little energy demand might be voluntary today but will become mandatory soon (national implementation of the European 2020 targets).
The quality and structure of information in databases relating to the energy performance of buildings are the foundation for a realistic projection of the development of energy demand for the buildings in the future. 16 European countries joined together in the project EPISCOPE and conducted national analysis on the relevant databases in connection with their national building stock.
Building certifications with their individual set of criteria provide guidelines for ecological, cost-efficient and sustainable constructions. Through these the negative environmental impacts could be minimized, the consumer comfort maximized and the quality of implementation according to the state of art, optimized. If the certification team is involved from the beginning of the planning phase, the best possible results with least additional costs can be generated.
While it is not compulsory under EU legislation to establish a centralised Energy Performance Certificate (EPC) register, almost all Member States gone beyond the obligations and set up systems to collect this data. In most cases, the main motivation for creation of such register, beside buildings data collection per se, was to support the quality control of the energy certification processes required by the Energy Performance of Buildings Directive.
To demonstrate how Energy Performance Certificates databases are being used for monitoring purposes, the key features of existing systems across Europe were examined using information from the Buildings Performance Institute Europe and Request2Action partners.
Since the certificates were first introduced in 2007, a number of European countries have stored data from Energy Performance Certificates in monitoring databases.
This EPC data can be used for many purposes and, in order to show how the information is being used in different countries, an expert workshop was organized in Belgium on November 4th, 2014.
