Data-based models for making the right decisions.

Forecasting model

The Wüest Partner forecasting model is used to generate small-scale demographic prognoses at the spatial mobility (MS) region and municipal level. Additionally, numerous location-specific scenarios and planning concepts can be modelled. The starting points are the municipal population levels, net migration figures and age structures. These, in turn, are influenced by a variety of location-specific factors including (among others): the initial situation with regard to development land reserves, labour market, construction activity and transportation infrastructure.

Recommended housing rent limits

The definition of housing rent limits for welfare recipients is a challenging task. The fact-based determination of the amount of support benefits is proving difficult. Wüest Partner is now contributing and has developed a model for determining rent limits in line with market conditions. The limits are defined individually for each municipality in Switzerland, taking into account the local market conditions of the relevant municipality. Further, the limits are updated regularly. The recommended rent limits intend to provide objective and appropriate support for social welfare recipients for housing. The underlying model is based on current observed rents, supply quantities and regularly updated empirical values.

Development-land prices

Development land prices are calculated using the so-called residual-value method, which involves deducting the construction costs from the market value of a property. The (residual) value difference, which may also be expressed in Swiss francs per square metre, is allocated to the land. The determination of the market values occurs on a usage-specific basis. The value of single-family houses is estimated using the statistical comparable-value method (hedonic valuation), while the market values of investment properties (multiple-family buildings, corporate, commercial/industrial properties) are calculated by risk-adjusted capitalization of the market rents.

Construction-market model

We have developed a detailed model to determine the present and future demand for construction services, products and materials. It is based on calculations of Switzerland's existing building stock, comprehensive data on construction investments and residential building, planning applications and permits (respectively for new construction and remodelling) as well as additional (projected) data based on the long-term perspectives of the relevant forecasting institutes. Thanks to diverse ongoing projects for associations and companies in the construction sector, we have direct practical experience and an in-depth knowledge of the construction process and the behaviour of building components (cost breakdowns, renovation cycles, etc.). All basic data are available at the municipal level.
