PPP goes green

Responsibility

HOCHTIEF PPP Solutions looks at projects from the perspective of their entire life cycle. We design living spaces and are aware that we consequently shape the surroundings of our projects and the environment for a long time.

We face up to this responsibility and wish to actively intensify the sustainability of our projects. This philosophy is firmly anchored in our “PPP Goes Green” vision.“

Sustainability

Sustainability is one of the five principles followed by HOCHTIEF. We are consequently always looking for integrated solutions which not only involve economic but also ecological and social aspects.

A7 Highway

With the A7 highway from Hamburg to the highway junction Bordesholm in Schleswig-Holstein, HOCHTIEF has expanded one of Germany’s most important traffic arteries. This not only provides enormous benefits for motorists but also for nearby residents, because the traffic now flows through noise barrier tunnels. HOCHTIEF Infrastructure took over the construction together with other partners.

Parks and small gardens are being built on top of the noise barriers. Thanks to the project, districts which were up to now separated by the highway are being brought together. Two green bridges are also planned and have partly already been built (see photo). Amongst other things, these enable deer to safely cross the highway.

More space for sustainability in Rodenkirchen

A little more than ten years ago, HOCHTIEF PPP Solutions rebuilt the comprehensive school in the Rodenkirchen district of Cologne. Now it is being expanded with a new building and a new gymnasium while the school continues to operate. Construction is scheduled to start in the third quarter of 2021, with the new buildings due for completion in the second quarter of 2023. Today, as then, the focus is on sustainable aspects:

For example, the extension building is being constructed in a climate-friendly passive design and will have 26-centimeter-thick insulation and triple-glazed windows. A comprehensive ventilation system with heat recovery and individual room control for heating and ventilation further contribute to environmentally friendly air conditioning. A photovoltaic system generates approximately 20,000 KWh of electricity per year.

During the construction and operation of the comprehensive school, various measures have already been implemented to reduce CO2 emissions. The building is characterized by its environmentally friendly energy supply. The entire roof area is used for a photovoltaic system. The students also have access to around 500 bicycle parking spaces, more than a third of which are covered and located directly on the main building. The photovoltaic system and excellent thermal insulation ensure that CO2 emissions are significantly reduced.

In October 2007, HOCHTIEF PPP Solutions was awarded the contract for the PPP project by the City of Cologne and financed and realized the design of the educational building that emerged from an architectural competition. The new building was completed on schedule at the end of 2009 and handed over to the city and the school community. Since then, HOCHTIEF PPP Solutions has been operating the school for 25 years.

For more sustainability: LED lighting for SAAone project A1/A6 highways

Motorists using highways in the Netherlands have certainly noticed it when they drive along the A1 or A6 highways around the Muiderberg intersection: The lights are crystal clear and the view is high-contrast and pleasant for the eye.

The reason for this: In recent months our SAAone team has replaced the conventional lighting on the highway section with modern LEDs—altogether more than 2,000 units. The LED not only provides a pleasant view for road users, but also has a longer service life and is more reliable than conventional lighting.

The life cycle approach under the PPP contracts provides an excellent opportunity to carry out improvements. "Naturally the implementation of LED lighting is currently a considerable investment for us, but because of the long term of the contract we have ample opportunity to recover this investment through lower maintenance and energy costs. The LED lighting is also very reliable. We scarcely need to worry about light failures, whereas we sometimes suffered from failures with conventional lights. The fact that we are also investing in sustainability thanks to the lower energy consumption makes LED an absolute win-win situation," explain Edith van der Wal and Jeroen van Rijn von SAAone. The client Rijkswaterstaat is also satisfied with the execution, since the new lighting was installed with virtually no restriction for motorists.

An excellent example of how we have specifically implemented our operational company knowhow of sustainability on site.

Corporate citizenship

Throughout the world HOCHTIEF shapes areas as living spaces and hence closely interacts with the people with whom and for whom we work. In all places where we work work we also assume social responsibility.

We use financial resources, commodity contributions, know-how and personal commitment to put this aspiration into practice.

In doing so we concentrate our donations and sponsoring activities on two prime issues which particularly relate to the company and our operating activities and which have an impact on sustainability: 1. Education and Promotion of Young Employees and 2. Design and Maintenance of Living Space.
