Characterizing the energy flexibility of districts using urban building energy modelling Open
This study applies an automated UBEM approach based on detailed physical building models of archetypes to assess the energy flexibility of an use case district attributed to the thermal mass. The energy flexibility is implemented by means …

Automated energy performance certificate based urban building energy modelling approach for predicting heat load profiles of districts Open
Urban building energy modelling (UBEM) for analysing buildings in their spatial and functional context is an arising method. Only a few UBEM procedures use detailed building simulation tools, which are essential for high temporal and spati…

Building stock characteristics of residential buildings in Salzburg, Austria based on a structured analysis of energy performance certificates Open
Heating and cooling of residential buildings is accountable for a significant share of the EU’s final energy consumption. In order to determine the current condition of the building stock and to implement appropriate measures and requireme…

Comparative analysis of thermally activated building systems in wooden and concrete structures regarding functionality and energy storage on a simulation-based approach Open
Thermally activated building systems (TABS) represent a practicable and energy efficient possibility for heating of buildings. Whereas TABS in concrete structures are well-established, wood-based materials are barely considered. State-of-t…

Simulation Model for Minimal Invasive Refurbishment Approaches Through Prefabricated Multifunctional Radiant Heating Façade Elements Open
This paper describes an approach for validating and calibrating a digital twin of a prefabricated multifunctional radiant heating façade element. In December 2017, a prototype equipped with sensors able to log surface and layer temperature…

Life-Cycle Costs of a Minimally Invasive Refurbishment Approach in Comparison to a Standard Refurbishment Open
The decision on constructing or renovating buildings is often based on construction costs; consequently, follow-up costs are not considered. Life-cycle cost analysis is a common method for assessing the economic viability of buildings over…

Passive conditioning of a large beverage ware-house by activating the buffer effect of the ground Open
A new production facility for a beverage manufacturer has to provide a storage volume for around 5 million bottles as a refrigerated warehouse. The maximum temperatures were not allowed to exceed 14 °C due to the quality requirements in th…

Comparison of the planned and the real energy consumption of the world’s first (Plus-)Plus-Energy Office High-Rise Building Open
The world's first office tower designed to feed more energy from renewable sources into the power grid than is required to operate and use has been built in the centre of Vienna. It is a refurbishment of an over 40 year old high-rise build…

Characteristics of a database for energy performance certificates Open
Funded reconstruction and newly constructed buildings are bound on the issue of an Energy Performance Certificate (EPC) in Austria. Due to that fact, there is a large pool of EPC. For the county Salzburg around 51.000 EPC are listed in the…
