Energy efficiency in Hamburg

Companies are able to significantly reduce their costs with intelligent energy-saving measures. This not only helps secure their competitiveness, but also already prepares them for medium-term changes in the energy market, such as price increases due to the growing scarcity of resources or energy taxes, and also actively contributes to climate change mitigation. Given that the energy prices are forever changing, it is important to retain an overview of consumption and to take an accordingly economical approach.

In June 2015, twenty-one executives from Belarus, Moldova, Kazakhstan, Ukraine and Uzbekistan completed their training with a focus on energy efficiency at the Wirtschaftsakademie Schleswig-Holstein GmbH. Primarily representatives from SMEs active in the construction industry, solar and climate technology production, consulting and engineering with a focus on new energy-efficient technologies, trends, measures and solutions came to Kiel. At the top of the participants’ agenda were passive houses and innovative residential building projects – smart houses with a focus on ecological construction.

The participants gained unique insights into the building projects and innovative solutions offered by DeepGreen Development GmbH during a two-day visit to the IBA international building exhibition in Hamburg. The MP participants were able to convince themselves that the awareness for a more sparing use of resources and consideration of ecological principles is also leading to a rethink in the construction industry, which future-oriented approaches exist in wood construction, and how traditional wood construction techniques can be reinterpreted with the impressive WOODCUBE project at the IBA. The WOODCUBE (sustainable living in a wooden cube) is a smart price house made entirely from wood that is also fully bio-recyclable.

At the IBA, the visitors also obtained comprehensive information on sustainable development of the Wilhelmsburg city district. The example of the Wälderhaus and other building projects completed in Wilhelmsburg were used to demonstrate how modern energy-efficient building technologies can be used. The executives also learned a great deal about the use of modern energy systems (photovoltaics, heat pumps, solar collectors). They then visited further projects, such as the energy bunker, Georgswerder energy hill, “Global Neighbourhood”, and “Gateway to the World”.

While the energy bunker and energy hill aroused interest and were marvelled at by the participants as unique and very specific projects, the other two projects proved themselves to be very tangible and realistic concepts. The “Global Neighbourhood” involves refurbishing old multiplexes in Wilhelmsburg. Outdated homes have been modernised and redeveloped as energy-efficient residences to retain the social housing’s status. The “Gateway to the World” project involves renovating a school to passive house standards and its expansion / redevelopment into an education centre. The “Gateway to the World” now comprises three schools, one kindergarten, a free children’s theatre and various extracurricular facilities.

Participants integrated countless innovative ideas, new trends and information into their projects. Preliminary successes have already been achieved. In Moldova, passive houses will in future be erected with German involvement in the project planning, and in Uzbekistan, a representative for a German manufacturer of sun and light protection systems has been identified for a joint venture.
