Energy, emissions and economic impact of the new nZEB regulatory framework on residential buildings renovation: Case study in southern Spain

Holistic renovation of a multi-family building in Greece based on dynamic simulation analysis

“…The analysis was performed for Zurich in Switzerland and they finally calculated a 29% reduction in the electricity consumption from the grid. Cerezo-Narváez et al (2021) examined the renovation of a building in Andalusia (South of Spain) with TRNSYS software. They concluded that the energy savings can be around 69%, while there is the possibility of 100% energy reduction.…”

Application of passive and active scenarios to a residential building in a dry and hot climate to achieve a positive energy building (PEB)

“…The findings revealed that most southern European countries are low prepared for NZEB implementation, particularly in retrofitting existing buildings. Recommendations included creating a common approach to develop NZEB targets and concepts in alignment with the regional context, aiming to transform recognized gaps into opportunities for climate-adaptive buildings [ [44] , [45] , [46] , [47] , [48] ].…”

“…The momentum for NZEB adoption is expected to grow, with upcoming mandatory standards for public buildings in Iran and private buildings soon to follow. The NZEB concept involves a symbiotic relationship between energy-efficient construction and the utilization of renewable energy, achieving a neutral balance of energy during a cycle of one year [ [41] , [42] , [43] , [44] , [45] , [46] , [47] ]. A NZEB reduces the need for electrical power and heat of course, and this diminished demand is fulfilled annually through a renewable energy supply system.…”

Circular Building Process: Reuse of Insulators from Construction and Demolition Waste to Produce Lime Mortars

“…In Spain, this percentage is reduced to 27.7% due to the better climatic conditions offered by being located in southern Europe [2]. However, this is still a high, and not inconsiderable percentage, meaning that every day more researchers seek to take action to evolve towards a more sustainable building sector [3]. If we continue to limit the problem to Spain, the gradual aging of the building stock increasingly forces autonomous governments to implement energy rehabilitation policies [4].…”
