The identification of techno-economically feasible decarbonisation paths and sustainability transitions for the built environment is a necessary task for research today and building stock renovation processes can act in synergy with innovative economic and technological development paradigms to achieve different types of benefits such as economic growth and employment, together with resource efficiency and sustainability for the whole sector.

High efficiency paradigms and rigorous normative standards for new and existing buildings are fundamental components of sustainability and energy transitions strategies today. However, optimistic assumptions and simplifications are often considered in the design phase and, even when detailed simulation tools are used, the validation of simulation results remains an issue. Further, empirical evidences indicate that the gap between predicted and measured performance can be quite large owing to different types of errors made in the building life cycle phases.

Cities consume 75 per cent of global primary energy and emit above 50 per cent of the world’s total greenhouse gases. For all their differences, Mediterranean cities share some of today’s most urgent urban challenges, such as climate change, environmental degradation and loss of biodiversity, sprawl and gentrification, migration and marginalisation, as well as shrinking economies and political turmoil. Policies at all levels call for more sustainable urbanisation models levering on Green Infrastructure (GI) and nature-based solutions essential in supporting energy transition.

Energy efficiency in existing buildings is a capital issue in Italy. Retrofitting interventions on buildings of historical and artistical interest have particular constraints and challenges. The present contribution deals with the description of the project and final results analysis of an experimental campaign of energy efficiency and acoustic improvement of a significant sixteenth-century building located in Rome, seat of the Chamber of Deputies of the Italian Parliament.

Hot and humid Extreme Climate Areas, like the United Arab Emirates, pose unique challenges for architects and engineers seeking innovative technologies for energy and environmental efficient building designs; at the same time, these regions are characterized by an innovative spirit that pushes to develop and implement projects to test renewable building technologies and solutions.

Negli ultimi anni i sistemi di Thermal Active Surface hanno acquisito grande importanza nel panorama scientifico per la possibilità che offrono di alte
capacità di risposte performative all’interno degli edifici dai punti di vista: architettonico, fisico-tecnico, economico. Tuttavia l’integrazione architettonica di
questi sistemi non è stata completamente esplorata nella rigenerazione urbana in area mediterranea finché l’evoluzione di materiali tradizionali da una parte
e l’introduzione di nano-materiali dall’altra non ne hanno reso possibili nuovi scenari di sviluppo.

To set conservation project in sustainable human development means to understand in-becoming reality, turning the static vision into a dynamic approach that considers life cycle as theoretical-methodological base, articulated in different and integrated steps. Historical architecture, in Mediterranean basin, assumes a type-morphological structure in coherence to microclimatic characters of site, defining the optimization of energetic relationships with surrounding natural environment.

In recent years, buildings have been equipped with building and automation control systems (BACS) that provide a reliable active energy efficiency measure for reducing energy consumption. These advanced systems allow to use and regulate technological implants in the best possible way in response to change in the external environmental conditions, ensuring at the same time the highest comfort for the building’s occupants.

ulti-threaded applications facilitate the exploitation of the computing power of multicore architectures. On the other hand, these applications can become extremely energy-intensive, in contrast with the need for limiting the energy usage of computing systems.
