With the \"GREEN high 3 Roofs | Facades | Courtyards\" funding programme for existing buildings, we want to expand the greening of roofs, facades and backyards. In this way, we are supporting the efforts of the people of Cologne to green and thus enhance the value of private house and courtyard areas close to their homes as well as commercial areas.<\/p>\n
The grants are awarded as part of the GR\u00dcN hoch 3 programme in accordance with the funding guidelines. By funding green roofs, fa\u00e7ades and courtyards in densely populated urban areas, we are helping to improve the local urban climate.<\/p>\n
The summer heat load is reduced, dust binding is improved and evaporative cooling is increased. The decentralised temporary storage of rainwater on roofs and in unsealed, green courtyards contributes to the retention of rainwater on site, increases evaporative cooling and reduces the damage caused by heavy rainfall events.<\/p>\n
In areas with high levels of pollution, the unsealing and greening of unused rear courtyards and the greening of facades and roofs can not only use rainwater for evaporative cooling during summer heat events, but also achieve additional environmental improvements and building optimisation.<\/p>\n
