Extension of the Building Stock Model for the SIA Efficiency Path
In order to compare the primary energy and greenhouse gas emissions of new construction and renovation projects with the target values, the Swiss Society of Engineers and Architects (SIA) has drawn up the information sheet (MB) SIA 2040. This makes it possible to check whether and how the energy policy objectives (energy strategy, climate change, 2000-watt society) work.
The information sheet from 2009 was valid until the end of 2014; a revision was necessary accordingly. It was expanded from residential, office and school buildings to all building types.
With our Building Stock Model (BSM), we developed the basis for the revision of the SIA 2040 (Efficiency Path) in the SFOE project (GEPAMOD). The consistency of the SIA 2040 target values per building and with the long-term energy policy objectives for Switzerland as a whole (Energy Strategy 2050) was thus also checked. We also demonstrated the significance of the characteristic values of other SIA standards and data sheets such as SIA 2024 (standard values per room use, SIA 380/4 (electricity in building construction), SIA 2032 (embodied energy) and SIA 380/1 (heat demand).
The Building Stock Model (BSM) enables us to carry out portfolio analyses, ex-post analyses and energy perspectives, and serve different needs.
