ONE receives preliminary Platinum certification from DGNB

The Deutsche Gesellschaft für Nachhaltiges Bauen e. V. (DGNB) has awarded the office and hotel high-rise building ONE with a preliminary platinum certificate. The ONE scores particularly well on indoor air quality, acoustic and thermal comfort and energy costs. ONE is almost 20 % below the requirements of the current German Energy Saving Ordinance (EnEV).

The DGNB awards the platinum certificate to buildings that fulfil the 37 sustainability criteria across the ecological, socio-cultural, functional and economic quality in planning and realisation categories to a standard well above average.

“The DGNB’s holistic approach to certification is particularly important to us because, alongside the immediate influence of the day-to-day operations of the building on the environment, it examines many criteria, which are especially important to our tenants. Alongside economic considerations, this most notably includes the quality of stay inside the building,” explains Michael Morgan, Managing Director of CA Immo Deutschland GmbH. Through a variety of measures, ONE has also amassed the highest possible number of points for criteria such as the interior air quality, risks to the local environment and acoustic comfort. The same applies to security, accessibility and service offerings in the building.

The development of sustainable real estate is an essential task for the entire sector, since real estate contributes around 40% of the world’s CO₂ emissions – a substantial amount. Consequently, for some considerable time now CA Immo has been incorporating stringent sustainability criteria into the project development phase, in order to realise green building projects. In the early 2000s, CA Immo was one of the pilot businesses of the DGNB with three buildings in the programme at that time. As a portfolio holder, CA Immo looks for the potential to save resources and lessen the burden on the environment, in existing buildings and ongoing projects, and pays special consideration to this when modernising buildings. Consequently, around 85% of the office buildings have been awarded with a sustainability certificate.

In view of digitisation and globalisation, fast and fail-safe Internet access is also extremely important for a company’s economic success, hence ONE has also paid great attention to providing the best technical communication equipment. ONE was the first office building and high-rise in Germany to receive WiredScore platinum certification, making it a pioneer in connectivity and digital infrastructure too.
