Proklima advises the German Federal Ministry for Economic Cooperation and Development

Policy advice, capacity building, awareness raising, and knowledge transfer are in the centre of Proklima’s activities. On behalf of the Federal Ministry for Economic Cooperation and Development (BMZ), it supports the German government and is actively involved in meetings and conferences on the Montreal Protocol such as MOP, OEWG and ExCom. Through numerous publications and events, it informs both the professional audience and the general public about the latest developments of sustainable cooling. One of its lighthouse projects is the so-called Cool Training on the save handling of natural refrigerants for trainers, technicians and policy makers.

3 in 1: en­er­gy ef­fi­ci­ent, ozone- and cli­ma­te-fri­end­ly

The office buildings at GIZ Bonn were built in 2015 (Mäander building) and 2020 (GIZ Campus). Sustainability was very important in the planning process, also in terms of ventilation and air conditioning. Even the refrigerants contained in the heat pumps have been carefully selected. The air conditioning system of the Mäander building is based on 66 kg propane while 450 kg CO2 are used in the Campus building. Both refrigerants are ozone- and climate-friendly due to their very low Global Warming Potential. The air conditioning system based on CO2 is custom-made and all necessary safety measures have been taken at both plants. "We feel absolutely safe", says Mr. Schäfer, technical director of the buildings services at GIZ Bonn.
