The vision for Ramboll’s new Head Office for 1,600 employees was to become a holistic and sustainable reference project.
Therefore the Head Office project group in close co-operation with Ramboll’s most experienced specialist in the field of sustainability implemented as many sustainable solutions in the project as possible.
The Head Office is connected to the Copenhagen district heating network which is one of the largest and most sophisticated in the world, supplying low carbon heat to a city with a population of more than one million people.
The transport system is also quite unique. Metro stations, buses and regional train connections are in a close proximity to Ramboll Head Office and you will see special bicycle lanes making it easy and safe to travel for cyclists to and from work.
The building was nominated to the international architectural WAN AWARDS 2010 with following remarks about energy:
The building is engineered with an holistic approach leading to long-term and creative results, reducing CO2 emission and integrating responsible climate friendly solutions. With reduction of energy through optimal daylight solutions, district heating and ground water cooling, reducing cooling needs by up to 85%, the building will have a low consumption of energy. Evaluating Energy, Transport, Water, health and wellbeing, the building archive a rating similar to BREEAM Good.
Lower CO2 emission and cost effective
One of the targets for Ramboll Head Office is that the primary energy consumption and CO2 emission should be lower compared to similar buildings and in a cost effective way. As heating and cooling can be provided efficiently the challenge has been to reduce the electricity consumption.
Actually the calculated energy consumption for the most consuming installations such as lighting, ventilation, pumps and cooling should be ten to fifteen percent below the energy requirements in the current building code.
Energy consumption for other equipment such as PCs, servers, printers etc. usually account for 20-30 percent of the total electricity consumption in an office building.
Energy efficient lighting with movement censors have been installed in the office work areas making the lighting intelligent and only in use when needed and thereby reducing the total energy consumption for lighting.
Pumps and ventilators in the building are controlled automatically and are only running when needed, reducing the energy consumption and the noise level in pipes and ducts.
In order to minimize stand-by losses and to reduce consumption all PC’s are labtops, all phones are smart phones and bulbs at the desks are normally not necessary due to natural light.
