heal.abstract
Green walls can be considered as building retrofit contributing mostly in indoor and outdoor thermal reductions as well as energy savings, both for heating and cooling. The term itself is very descriptive: a wall that is either free-standing or part of a building, featuring several kinds of vertically installed vegetation. Two distinct concepts constitute the green wall technology: Green façades and Living walls. Living walls provide a wide range of benefits according to Literature. On the other hand, green façades are not such an effective concept, a fact that was corroborated during an energy study on a Multifamily Building in Cyprus, conducted for the purposes of the present thesis. If important barriers -including both technological and economical obstacle-will be surpassed and additional improvements –including subsidization and advertising- occur, then much more green wall projects will be installed, proving thus their beneficial nature in the environmental, economic as well as social and aesthetical field.
