TL;DR: In this article, the authors present the outcomes of the joint workshop and interactive discussion, by focusing on technical, financial, and social added values, barriers and challenges, in the context of the building renovation processes tackled by the four H2020 innovation actions.
Abstract: With a low rate of new building construction and an insufficient rate of existing building renovation, there is the need to step up the pace of building renovation with ambitious performance targets to achieve European Union (EU) climate change policies for 2050. However, innovative technologies, including, but not limiting to, plug and play (PnP) prefabricated facades, information and communications technology (ICT)-support for building management systems (BMS), the integration of renewable energy systems (RES), building information model (BIM) and building performance simulation models (BPSM), advanced heating, ventilation, and air conditioning (HVAC), advanced geomatics, 3D-printing, and smart connectors, cannot alone solve the problem of low renovation rates of existing buildings in Europe that is hindering reaching of EU-wide targets. A workshop was held at the Sustainable Place Conference 2018 to present, with an integrative approach, the experiences from four H2020 innovation actions, i.e., 4RinEU, P2ENDURE, Pro-GET-OnE, and MORE-CONNECT, which were united by their central aims of improving building energy performance through deep renovation practices. This article presents the outcomes of the joint workshop and interactive discussion, by focusing on technical, financial, and social added values, barriers and challenges, in the context of the building renovation processes tackled by the four projects. Conclusive remarks converge on the identification of open questions to address future innovation opportunities, as well as some recommendations to be used at a policy level and/or in future implementation projects.

TL;DR: In this paper, a survey was carried out on potential approaches and indicators that could be used for the NZEB renovation definition of existing single-family houses in Poland and the main objective of the survey was to propose possible requirements for NZEBs renovation definition in heating dominated climate.
Abstract: The main objective of this article is to propose possible requirements for NZEB (nearly zero-energy buildings) renovation definition in heating dominated climate A survey was carried out on potential approaches and indicators that could be used for the NZEB definition of existing single-family houses in Poland The process of determining requirements for the NZEB renovation definition was divided into two stages The cost-optimal U-values of the building’s envelope were initially calculated and, based on them, the energy demand for heating (QH) and the reduction of non-renewable primary energy demand (QP) were estimated The calculations were made for different energy prices, locations, and two building models Based on them the requirements for cost-optimal renovation (QH ≤ 60 kWh/(m² year), QP reduction ≥ 75%) and NZEB renovation (QH ≤ 40 kWh/(m² year), QP reduction ≥ 80%) were proposed In contrast to definitions using only a maximum level of QP, two indicators were used Such a solution is appropriate for existing buildings because it prevents the situation in which only renewable energy sources (RES) (with a low primary energy factor) will be applied in order to decrease the primary, non-renewable energy demand

TL;DR: In this article, the feasibility of using the heat demand -outdoor temperature function for heat demand forecast was evaluated in the district of Alvalade, located in Lisbon (Portugal), using three weather scenarios (low, medium, high) and three district renovation scenarios (shallow, intermediate, deep).
