Reacting to the recent UN reports on the need for accelerated action on reducing the effect of buildings on the climate change, Journal of Sustainabily gave professors Kalamees  (TalTech, Estonia) and Bomberg (Clarkson U, NY, USA) a privilidge to collect papers for development a special issues on retrofit (renovation, rehabilitation, envirornmental upgrade of existing buildings of any type, shape and character including histrotic buildings) with the focus on Integration of Energy and Indoor Environment in Buildings. Today, an achitect loooking for a technology bliueprint may find 138 research projects on Horizon 2020 or 150 papers published by each of the leading publishers like Elsevier or MDPI and another 100 on Building Automation in IEEE, Sprringer or Informa. With the overflow of publications we need to give a reader a focus on new developments in a holistic, multi-disciplinary approach to methods for new and retrofitting construction.
