Sustainabilty and Renewable Energy Supply
Saturday, 4 May 2019, 9:00 am, Großer Saal (ground floor), simultaneous translation into English
The term “Systems Engineering” can sometimes sound boring and opaque, but it will be a crucial feature of our future buildings, cities and societies. The Passive House Institute has already taken a “Systems Engineering Approach” to the new PER standard, where the inclusion of renewable energy potential and generation are accounted for in building performance. In this session the details of the PER system and the successful integration of Passive House buildings with local renewable energy production will be discussed.
Wholistic design philosophies, and the need to account for the entire life-cycle of a building, are a significant topic across the globe and are already being accounted for in many business’s annual sustainability reports and this important topic will also be discussed in this session. This session also features a lecture delving into the social, as well as environmental, aspects of energy efficient buildings and again emphasises the fact that Passive House buildings have positive benefits to a number of societal indicators.
PER and Passive House: Dream Team
|Renewable energy is only available to a limited extent. The Passive House with its low energy requirement complies with this limitation. This is especially true in winter, when little solar energy is available and there is a high demand for heat. In the future there will be a need for short- and long-term energy storage in order to avoid supply gaps. However, the storage losses are considerable, which results in another argument for highly efficient buildings. The energy that is not needed in winter does not have to be stored with high losses. The concept of Primary Energy Renewable (PER), according to which Passive Houses can be evaluated, automatically takes these losses into account.|

Life cycle analysis of residential buildings of different construction methods
|The life cycle analysis of a single-family house using various designs provides the client with an important basis for decision-making. The analysis examines the complete life cycle from manufacturing, to the use phase, to the disposal phase of buildings in heavy and lightweight construction. Each design has specific strengths. The results demonstrate the importance of energy-efficient design in the life cycle of the building. Ultimately, the ecological balance of the building can be improved, above all, through a long service life. This requires a high-quality execution and a thorough planning of the building from the start.|
