Drees & Sommer

Competent, successful for customers, independent of third parties! Whether building construction or infrastructure measures, project management, real estate consulting or engineering: around 2,400 employees at 41 international locations and representative offices are committed to the success of our clients. Drees & Sommer has been following a consistent path for more than 45 years. And it has a name: “the blue way”. Generally economical, but as sustainable as possible! Together with EPEA International Environmental Research in Hamburg, Drees & Sommer stands for Cradle to Cradle® in the construction industry and brings together clients, investors, architects and product manufacturers to promote the topic.


HOINKA GmbH is a company that specializes in services related to sustainable construction (green building). As an experienced DGNB auditor, LEED AP and BREEAM assessor, HOINKA GmbH carries out green building certifications. In addition to the development of innovative building concepts, HOINKA GmbH offers web-based software tools and building product databases. In times of digitalization in the construction industry and the trend towards sustainable materials, our goal is to create planning security for building owners, architects, planners and construction companies. Our job is to pave the way for this and take the pressure off the customer.


An opaque and confusing multitude of product labels, building certificates and material declarations makes it almost impossible for building owners and planners to keep track of everything. Product manufacturers, on the other hand, are constantly confronted with requests for proof and declarations. In addition, the search for product-related BIM objects and life cycle assessment data has recently been added, which results in a further increase in complexity.

Our vision is to use the Building Material Scout to provide easy access to healthy, intelligent and sustainable materials and building products for all those involved in construction – financiers, builders, project developers, architects, planners, construction companies and operators. We are convinced that this will enable us to make a significant contribution to better construction quality.

The Building Material Scout evaluates and structures material-related information and thus facilitates the search for suitable materials and products. Predefined or individually configurable search masks make it possible to select the right materials – for example for green building certification. The Building Material Scout paves the way for future-oriented planning, construction and operation – not least by bundling all current information in one place.
