Green Buildings - Sustainability Certificates

Certification of a large number of our fund properties is an important part of our commitment to sustainability. This focus on sustainability in the building sector is based on a comprehensive approach to the property life cycle using environmentally-friendly technologies, while ensuring profitability at all times. Property sustainability certificates allow compliance with sustainability criteria to be measured and compared based on nationally established and internationally recognised certification systems. These include, for example, the Building Research Establishment Environmental Assessment Method (BREEAM*), Leadership in Energy and Environmental Design (LEED®) and the German Sustainable Building Council (DGNB).

Certification systems - Similarities and differences

A comparative overview of the market-relevant certification systems in Europe:


Our portfolio comprises 313 outstanding green buildings worldwide

Our high quality portfolio boasts 313 certified sustainable properties with a market value of over EUR 35 billion in December of 2021, including, for example “The Edge” in Amsterdam, “Kings Place” in London, “Tower 185” in Frankfurt, Stantec Tower“ in Edmonton, Canada, “Parkview” in Prague and the “Generation Park Z” in Warsaw, as well as the "vidaXL" logistics building ensemble in Venlo, the Netherlands.

The Edge – Rating: "Outstanding"

Deka Immobilien's The Edge office building in the Zuidas district of Amsterdam is one of the most innovative buildings in the world and sets new standards for the sustainable workplaces of the future: intelligent architecture, sophisticated design, state-of-the-art technology, maximum comfort and an optimal indoor climate. What's more, all of these features are combined in a building that generates more energy than it uses.

BREEAM Outstanding
The Edge received BREEAM New Construction sustainability certification with a rating of "Outstanding", and from 2014 to 2016 achieved the highest score received so far for a sustainable office building anywhere in the world. In 2016, The Edge also won the BREEAM Award in the "Office New Construction" category.


The Edge is better than energy-neutral — it is energy-positive. Intelligent materials and technology, such as electrochromic glass that allows building users to control how much light is let through, smart LED lighting systems and clever architecture ensure efficient energy consumption. The Edge was built to allow optimal use of sunlight; daylight illuminates the rooms without affecting the indoor temperature. There are also 65,000 square metres of solar panels on the façade and the roof, supplying enough energy to cover all the building's electricity requirements. The energy is fed into a geothermal system to make the building self-sufficient in terms of heating and cooling; however, it can also be used for other tasks like charging electric cars.

The specially designed nature-oriented green space around the building provides a home for bees and bats, as well as insect hotels. The green space separating the building from the nearby motorway serves as an ecological corridor that allows animals to cross the area safely. Rainwater collected on the roof of the building is used to water the green space.

Smart Office
Around 30,000 sensors and a mobile app for the building provide intelligent networking. Other features such as automated parking space assignment (with e-charging stations), a smart room booking and lighting system and continuous optimisation of temperature, light intensity and air quality make the building both highly efficient and extremely comfortable.

Parkview – Modern sustainability

Parkview sets new standards in terms of eco-friendly design, sustainable economic efficiency and comfort. Completed in 2020, this office building is located in the established Pankrác sub-market of the Prague 4 district and offers excellent public and private transport access. The building provides around 16,000 square metres of space over 9 floors and is leased to a number of tenants under long-term leases.


Multiple certifications
Parkview reflects the spirit of the current era and combines sustainable features with modern technological innovations to satisfy the highest standards. The office property received the maximum "Platinum" certification under the US LEED standard with a score of 97 points. WELL Gold Core & Shell certification and the WELL
Health-Safety rating from the international WELL Building Institute also recognise the many measures implemented for the health and well-being of building users.


High energy efficiency
The building's façade elements and innovative air-conditioning system provide an extremely high level of energy efficiency. One of the highlights of the building is the energy-recovery system that produces electricity when the lifts are descending.

Location and accessibility
Parkview is set in a prestigious location near the park in Prague 4 and provides excellent accessibility by car and public transport. Tenants can also use the facilities provided for cyclists.

The design of the building – including modern, flexible office areas and conference rooms with business grade Wi-Fi and a roof terrace with bar, grill and seating – places special importance on state-of-the-art office comfort and user well-being.
The U-shaped floor layout and glazed atrium allow daylight to enter and provide an unobstructed view of the neighbouring park.

Resource conservation
The building has an advanced energy-saving LED lighting system with motion and daylight sensors. Using rainwater to water the green spaces reduces water consumption.

Mahon Point – Ireland's most sustainable shopping centre

The Mahon Point shopping centre in the Irish port city of Cork is one of the largest shopping centres in the country, boasting over
80 shops and restaurants on two levels. It sets new standards for environmentally friendly, resource- conserving sustainable construction. In 2015, Mahon Point became the first shopping centre in Ireland to receive BREEAM In-Use certification.

Farmers' market
The Mahon Point farmers' market is the largest organic market in Cork. More than
50 stalls offer high-quality foods, much of it from local producers. The market's vision is to be "as plastic free as possible and fully sustainable" — for example, the market vendors have all committed to using compostable packaging for all of the food sold.

Charging stations for electric cars
Mahon Point promotes electric mobility and provides charging stations for electric car drivers. The 4x 250-kW Tesla Supercharger stalls can be used 24 hours a day.

Green energy
Since 2017, the centre has operated exclusively using "green energy" — a combination of wind power, solar energy, bioenergy and hydroelectric power.
A large percentage of this energy is supplied by the photovoltaic system on the roof of the shopping centre: Around 1,000 m² of photovoltaic panels produce around 160,000 kWh of solar electricity annually.

All the waste generated at Mahon Point is recycled. Thanks to professional waste management, an average of 900 tonnes of paper, plastic, glass, metal and compost are collected for recycling every year.

LED lighting
From car parks, to Christmas lights, to escalators: Mahon Point reduced its power consumption significantly by converting to energy-saving LED lights.
