How much redundancy does an energy system really need? Do power peaks have to be fully covered - or are time-limited peaks permissible? What is the optimum machine size to ensure comfort or operational safety?

As part of the comprehensive redesign of the Arkadenplatz in the centre of Davos, a new cinema with 138 seats and a multifunctional stage was built. Kuster + Partner AG was responsible for the building physics, energy, room and building acoustics.

The "Tower Buchs", a striking eight-storey office and commercial building, is being built at the southern entrance to the town of Buchs SG. On behalf of Frickbau AG, the H2O-Plan team was responsible for the building technology planning for this new multi-purpose building. BOP was called in to optimise the dimensioning of the building technology using dynamic building simulation.

In a project funded by Innosuisse, Amenti and the Scuola Universitaria Professionale della Svizzera Italiana (SUPSI) have developed a planning methodology that enables the precise prediction of yields from roof- and façade-integrated photovoltaics. It automatically takes into account shading caused by building offsets and the shadows cast by neighbouring buildings, trees and terrain.

The National Sports Centre Magglingen (NSM) is an important training, sports and congress centre for Swiss sport. Gruner Gebäudetechnik Bern has been carrying out various renovation works on the NSM's building services systems since 2020. One of these measures concerns the Jubilee Hall, the training hall for artistic gymnasts. The hall of the existing building from the 1990s was originally heated exclusively by supply air...

There are currently no specific standards for natural or hybrid ventilation concepts. Absolute targets are often required that cannot be fully achieved with the variable outdoor climate as a source of energy and fresh air. By foregoing comfortable perfection, mechanisation and installations can be reduced, which lowers costs and emissions. Passive concepts usually require less building technology and reduce...

In the Sky high-rise building in Stettbach (client: Publica), CFD simulations were used to test the feasibility of the following two ventilation optimisations. On the one hand, it was investigated whether the ventilation ducts in the ceiling of the flats could be dispensed with. On the other hand, the simplification of the ventilation duct network in the underground car park was analysed.

In order to cope with the growing flow of passengers and commuters at Zurich Airport, the northern part of the airport shopping centre is being completely renovated with the ELP project. The central element of the project is a new twelve-metre-high food hall between car parks 1 and 2 with fixed stands, food trucks and a bar.

Medium-sized and large car parks need a sufficient exchange of fresh air so that the concentrations of carbon monoxide and nitrogen oxides do not become dangerously high. With the help of a flow simulation (CFD), the distribution of these particles can be tracked, analysed and optimised.

The SPF Institute for Solar Technology was commissioned by the HVAC engineering firm Tri Air AG on behalf of SBB AG Immobilien Bewirtschaftung to carry out a simulation study to examine the need for active cooling and the total energy requirement with different variants.
