Housing is the main environmental impact generator (62 %) of the whole building sector, but it also has the greatest reduction potential. Enhancing its performance is thus crucial to sustainable development. Social Housing (SH) represents a critical asset within the residential segment, due to the recurrent investment shortage and several environmental, social, and economic related implications. In Italy, SH is held by around one hundred public agencies facing endemic resource constraints for both maintenance and retrofitting, which are limited further by a diffused lack of information regarding the conditions and features of the buildings they manage. In cooperation with an Italian SH agency (ACER Bologna), we developed a speedy tool to compare the technical and economic effects of different refurbishment scenarios on a case-by-case basis. This is not a tool to manage retrofitting works, as the many already available, but a means to help large housing managers overcome the intention-action gap that limit their capacity to properly prioritize interventions based on reliable information. The research focuses on the validation of the fast procedure for estimating the baseline energy scenario, arguing that the relatively small inaccuracies are irrelevant for the scope of the tool and are compensated for by the time saved.

Designing sustainable and, at the same moment, resilient buildings is a necessity to reach the UN Sustainable Development Goals by 2030. However, these two building design approaches - sustainability and resilience - are usually treated separately. Typically, resilience-improving strategies are placed only after a disruptive event and not at the design stage. It is clear that there is a substantial intersection between sustainability and resilience and this manuscript aims to determine more precisely the commonalities and contradictions seen in building design sustainable and resilient approaches as crucial elements for improving their cooperation in buildings. To accomplish this, the authors qualitatively analysed two case studies - respectively claiming to be sustainable and resilient - to understand if a sustainable building can also be considered resilient and vice versa. This paper is addressed to the private and public sectors that have a decisive role in building design and are determined to take tangible steps to influence decision-making and resilience-based solutions already at the design phase. In conclusion, once the commonalities of resilience and sustainability are highlighted, a building designed as sustainable or resilient will be in line with both long-term perspectives.

Building envelope design is rising in relevance and, within this specific context, the application of passive and climate adaptive building shells (CABS) is investigated as an opportunity for energy savings and improvement of users' thermal and visual comfort. The paper reports a research concerning the climatic based development of a customized dynamic façade based on a passive self-adaptable system to climatic conditions via actuators. The solution is designed with the aid of a customized workflow based on Ladybug Tools, which is calibrated according to recorded thermal-mechanical behaviours and allow to predict the energy and thermal/visual comfort dynamic performances. The system is tested in four European climates and sky types, tracing the scenarios of its adaptability under various settings. The results indicate that the system by its constant mechanical changes due to the variation of temperatures provides a higher degree of adaptation, energy-saving and indoor thermal and visual comfort.

Renovation processes as well as the development of new housing will be relevant fields of interventions in shaping the future of contemporary cities and strategic sectors to revive industrial activity, job markets and competitiveness. At the same time they represent the greatest opportunity to face global environmental challenges, such as climate change and natural resources scarcity, through innovative perspectives assuming the built environment as a whole and no more individual buildings as the core of design strategies. The rapid and wider diffusion of “eco-innovation” can have a leveraging effect on environmental, as well as on economic and social improvements, by enabling win-win synergies able to increase the rate of successful processes both in terms of architectural and economic sustainability. As incremental innovations alone cannot achieve an absolute decoupling of economic growth from environmental impacts, increasing the market potential for more radical and systemic eco-innovations is becoming of particular importance to enable a long-term transition to a greener economy. In recent decades, environmental analysis in the built environment has focused on issues relating to life-cycle and energy performance at the scale of individual buildings, establishing energy savings technologies and design strategies that reduce energy use and improve indoor comfort. There has been comparatively little focus on the impacts on the outdoor microclimate at district or neighbourhood scale. A joint study, involving the Universities of Bologna and Westminster, is focused on climatic adaptive-mitigation strategies to support the transition of the built environment to a low-carbon society. The paper outlines the general framework and methodology of the study providing a picture of the design strategies and innovative approaches. In order to encourage industry to take up economic opportunities from developing and diffusing eco-innovative products and services, the study examines the key elements for fostering initiatives at an urban scale, the principal drivers to boost transition, the strategic tools as well as the main barriers to reach successful interventions.

A considerable part of recent EU policies is currently addressed at developing effective measures to support the transition towards a low carbon society according to the principles and goals of Roadmap to 2050. In this general framework the links between the development of low-emission strategies and climate-resilient approaches to buildings play a key role. As most part of the existing building stock was built before the 1980s, retrofit and renovation actions are widely investigated. Despite progress in this field, relatively little attention has been given to the connections between the achievable energy savings and the energy investment needed to pursue the renovation process and to how technological choices can impact on the energy balance according to a multi-criteria perspective. The paper will explore how different technologies and design solutions to building envelopes cladding contribute to the reduction of the heat gains in urban environments and how appropriate adaptive strategies can further mitigate against accelerated greenhouse emissions. It will discuss the relationship between individual building performance and consequent effect on external environment. The effects of technological and material choices are evaluated for some design scenarios and conditions in order to develop an indicative impact mode. [ABSTRACT FROM AUTHOR]

Huge efforts have been made in recent decades to improve energy saving in the building sector, particularly focused on the role of façades. Among the explored viable solutions, climate-adaptive building shells [CABS] consider promising solutions to control solar radiation, both in terms of illuminance and heating levels, but are still piloting these solutions due to their complex designs and necessary costs. The present study aims to provide a speedy but reliable methodology to evaluate the potential impacts of adopting active/passive CABS systems during the preliminary design stage. The proposed methodology allows the evaluation and comparison, when multiple options are considered, of the effects of each solution in terms of the energy needs, thermal comfort and lighting, while reducing the required effort and time for an extensive analysis of the overall building level. This is based on the use of a "virtual test room" where different conditions and configurations can be explored. A case study in the city of Bologna is included for demonstration purposes. The achieved results support the decisions made regarding energy behavior (over/under heating), indoor comfort, lighting and energy at an early design stage. [ABSTRACT FROM AUTHOR]

- Abstract
The evidences of the influence of climate change (CC) in most of the key sectors of human activities are frequently reported by the news and media with increasing concern. The building sector, and particularly energy use in the residential sector, represents a crucial field of investigation as demonstrated by specific scientific literature. The paper reports a study on building energy consumption and the related effect on indoor thermal comfort considering the impacts of the Intergovernmental Panel on Climate Change (IPCC) 2018 report about temperature increase projection. The research includes a case study in New York City, assuming three different scenarios. The outcomes evidence a decrease in energy demand for heating and an increase in energy demand for cooling, with a relevant shift due to the summer period temperature variations. The challenge of the last decades for sustainable design was to increase insulation for improving thermal behavior, highly reducing the energy demand during winter time, however, the projections over the next decades suggest that the summer regime will represent a future and major challenge in order to reduce overheating and ensure comfortable (or at least acceptable) living conditions inside buildings. The growing request of energy for cooling is generating increasing pressure on the supply system with peaks in the case of extreme events that lead to the grid collapse and to massive blackouts in several cities. This is usually tackled by strengthening the energy infrastructure, however, the users' behavior and lifestyle will strongly influence the system capacity in stress conditions. This study focuses on the understanding of these phenomena and particularly on the relevance of the users' perception of indoor comfort, assuming the IPCC projections as the basis for a future scenario.

Many actions have been undertaken worldwide to cope with climate change and to effectively reach the 2030 Agenda for Sustainable Development. Top-down approaches, based on both policies for the development of enabling technologies and incentives to promote their wide applications, have been largely adopted in most of the cases. However, the potential contribution of changes in individual behaviours still represents an underestimated field of improvement, despite many scholars have already evidenced their considerable expected impacts. This paper presents the first outcomes of a study on the role of citizens’ behavioural change in reducing GHG emissions, focussing on the functions and performed activities at household level. Starting from a review of the emerging body of literature on the topic, a map is drafted linking the people’s actions and choices and their most relevant effects on each of the environmental categories they can interact with. The mapping provides a list of suitable practices and lifestyles shifts to be adopted, organized by categories and weighted by their emission potential reduction on the whole households’ carbon footprint. This results in a sort of easy-to-read console allowing citizens to operate according to more informed decisions within their homes, thus accelerating the sustainable transition by bottom-up initiatives.

Climate change and the deriving impacts on the built environment certainly represent one of the most challenging issue for several key players involved in shaping the cities of tomorrow. This is not simply a matter of adapting buildings to new requirements, but rather to rethink the way the urban fabric reacts to new and sometimes unpredictable phenomena. The process is related to increasingly evident extreme conditions in the summer time, that strongly improve the energy demand for cooling with negative impacts on the energy balance as well as on thermal comfort conditions of the end users and of urban population with severe implication on health and wellbeing. Outdoor comfort depends on a number of inter-related factors: the characteristics of the built environment, the relationship between materials and energy use, global climate change and local micro-climate: Temperature, Solar Radiation, Wind distribution, Wind Speed, Absolute and Relative Humidity. The objective of this specific study is to test the microclimate modeling of a city portion in a demo-case – a plot of building blocks with inner courtyards – as a tool for supporting the regeneration phase addressing technological choices and design solutions to improve outdoor comfort conditions. The outcomes of the performed envi-MET simulations, comparing the situation before and after intervention, are consequently discussed. In the specific case, the developed project involving the courtyard has led the Thermal Comfort perception, evaluated in terms of PMV, to shift from “very hot” (+3.50, +4.00 red zone) and “very very hot” (above + 4.50 violet zone) to “Warm” (+1.50, +2.00) at urban plot scale.
