Procurement Practices

Organizing the purchase of materials centrally via Vonovia’s Procurement department helps to minimize the risk of hazardous or toxic substances being used. In order to protect our employees and tenants alike, we ensure material safety using the systematic TÜV Rhineland Toxic Materials Management System (TOGs®). All information is recorded, evaluated and documented centrally in an online toxic materials register. This provides us with an ideal basis within our own craftsmen’s organization for conducting risk assessments and developing operating and handling instructions. We use our contracts, general terms and conditions of purchasing and our Business Partner Code to make sure that our subcontractors adhere to our standards. The aim is to minimize risks. When it comes to , for example, we only use selected and tested materials and explicitly subject the companies performing the measures to the obligation to use them. We are also constantly keeping an eye on product innovations in order to create the best product for our customers. In 2017, for example, we planned a facade insulation project using hemp in Dortmund and are increasingly looking at the use of mineral fiber as an insulation material.

Our Business Partner Code for subcontractors and suppliers sets out our expectations regarding integrity, reliability and economically and legally compliant conduct and ensures that our business partners meet these expectations. The Code stipulates, in particular, that corruption must be combated, that illicit employment must be ruled out, that the legal minimum wage must be paid and that valid German regulations on occupational safety, employee rights and the environment must be observed.

In 2018, we will increase efforts to review our guidelines and codes and develop a concept for annual supplier audits in order to also continue systematically reducing potential risks.

Modernization Measures
Modernization measures are long-term and sustainable value-enhancing investments in housing and building stocks. Energy-efficient refurbishments generally involve improvements to the building shell and communal areas as well as the heat and electricity supply systems. Typical examples are the installation of heating systems, the renovation of balconies and the retrofitting of prefabricated balconies as well as the implementation of energy-saving projects, such as the installation of double-glazed windows and heat insulation, e. g., facade insulation, insulation of the top story ceilings and basement ceilings. In addition to modernization of the apartment electrics, the refurbishment work upgrades the apartments, typically through the installation of modern and/or accessible bathrooms, the installation of new doors and the laying of high-quality and non-slip flooring. Where required, the floor plans are altered to meet changed housing needs.
