Comparison of automatically created residential building simulation models with manually created building models
Vergleich von automatisiert erstellten Wohngebäudesimulatiosmodellen mit manuell erstellten Gebäudemodellen
Innovative approaches and technologies are needed to meet the German government's climate protection targets and the increasingly loud calls from the public and experts for even earlier climate neutrality. In 2022, the building sector was responsible for 34% of global energy demand and 37% of energy- and process-related carbon dioxide (CO2) emissions, which is why the energy-efficient design and use of buildings is of central importance.
In order to implement this, the use of building simulation programs is essential in the construction industry. The aforementioned software makes it possible to estimate the behaviour and energy flows of a building, maximize the thermal, acoustic and visual comfort of the interior and ultimately optimally dimension the building to be constructed and its technical building equipment to meet the requirements and avoid planning errors in advance. During this process, renewable energy generation, such as photovoltaics, heat pumps or geothermal energy, can also be taken into account. All these factors are essential when assessing the sustainability of a building.
However, due to the continuously increasing requirements for energy efficiency and sustainability in the building sector, the costs incurred for the planning of these properties, among other things, are also rising. This is where simulation using generic buildings comes into play. These are generated on the basis of a library stored in the program in just a few simple steps, which means that although they do not correspond to the future building in all aspects, they can be created in the shortest possible time. This in turn saves financial and human resources. Generic buildings also offer a great opportunity in view of the shortage of skilled workers in the construction industry. The use of building simulation programs makes it possible to automate the planning process and make it more efficient. Valuable insights into the thermal behaviour of the building can be gained quickly at an early stage, optimization potential can be identified and the energy efficiency of buildings can be significantly increased. This not only leads to lower energy consumption and a reduction in operating costs, but also supports the achievement of sustainability goals.
Generic Building in VICUS Building
Ultimately, generic building models and their validation using simulation programs can contribute to the successful implementation of the energy transition and compliance with climate protection targets. They enable more efficient planning, make optimum use of scarce engineering resources and lead to considerable cost savings. These technologies therefore represent an important building block for the sustainable design and use of buildings in our society.
