Comparing Energy Improvements and Financial Costs of Retrofitting Interventions in a Historical Building

In Italy, energy improvements of historical buildings are one of the key aspects to reach the EU 2020 goals on energy efficiency. Many papers are available in literature to recover and retrofit historical buildings, considering different types of interventions aimed to increase energy efficiency in existing building. Considering the most common retrofit interventions in historical building, this paper focuses on the estimation of the energy improvements and related financial costs of four considered scenarios on the building envelope of the “pharmaceutical chemistry” historical building located in the Sapienza University Campus of Rome. Additionally, a cogeneration system and the installation of a PV system have been included among the considered scenarios, in order to analyze their energy performance jointly with feasible retrofitting interventions. Research methods included a dynamic simulation of building thermal loads in the current state and in the scenario after each considered intervention carried out using TRNSYS software. Furthermore, yearly savings, investment cost and payback periods have been evaluated for each considered scenario, taking into account both the purchase prices of the saved energy and the amounts needed to realize related retrofitting interventions. In conclusion, among the feasible interventions in historical buildings, the obtained results provide useful data about what strategy offers the best energy performance improvement if compared with its financial costs. Results could provide recommendations for other historical buildings that need retrofitting interventions for improving their energy efficiency

Local Energy Efficiency Interventions by the Prioritization of Thermal Zones in an Historical University Building

Architectural constraints are a crucial aspect in energy retrofitting of historic buildings. Usual global interventions are often not allowed since preserving historical values of the building stock is mandatory. In this paper, the authors provide an alternative procedure by identifying the most profitable local interventions in order to maintain the architectural values during the restoration and energy retrofitting operations. So, thermal zones prioritization is the key element considered in this study. Its aim is to analyse which energy efficiency measures could be applied to a listed building, but at certain technological elements rather than a unique choice for the entire building envelope. Thus it will prove that you can work with individual elements of the building without compromising the protection of architectural good. The attention was placed in promoting single measures and improving the quality of the built environment. The case study is an historical building in Rome, currently used for university purposes. The analysis was carried out through a building simulation model so that to assess the building energy performance before and after the selected interventions. The chosen software is TRNSYS. This approach shows how interventions, usually not applicable at the building scale, would be beneficial if applied at local scale such as a single thermal zone or a single technological unit. The authors built a reference scenario and, for each identified thermal zone, tested the energy efficiency improvement in terms of heating demand reduction coming from the hypothesized local intervention

Associations of suicidal ideation with opioid/prescription drug use, violence, food insecurity, and community factors among New Hampshire high school students

Purpose: Suicide is the second leading cause of death for New Hampshire (NH) youth. Evidence-based public health emphasizes the use of data for translating research into practice/policy. We utilized data from the Youth Risk Behavior Survey (YRBS) to support community-academic partnerships and inform suicide prevention interventions. Methods: Data from the 2011 NH YRBS, a cross-sectional survey of 9th-12th grade students, were analyzed. Gender-stratified, adjusted odds ratios (aORs) and 95% confidence intervals (CIs) were estimated using logistic regression models (SAS 9.4, ProcSuveylogistic) to evaluate associations between suicidal ideation (seriously considering attempting suicide within the past 12 months), violence (e.g., physical bullying, cyber-bullying, forced sexual activity), opioid/prescription drug use, food insecurity, and perceptions of being valued by one’s community. Results: Overall, the prevalence of suicidal ideation was 14.3% (females 16.8%; males 12.2%). For both genders, higher prevalence of suicidal ideation was observed among students in grades 9 (15.6%) and 10 (17.8%) compared to grades 11 (11.6%) and 12 (11.3%). In adjusted models, among girls, suicidal ideation was positively associated with the use of opioid/prescription drugs (aOR: 1.38; CI: 1.13-1.67)), violence (being forced to have sex (aOR 2.32 (CI 1.12-4.81)); being bullied on school property (aOR 2.28 (CI 1.31-3.97)), and food insecurity ((aOR 1.36 (CI 1.02-1.81)). Among boys, suicidal ideation was positively associated with opioid/drug use (aOR 1.25 (CI 1.04-1.49)), cyberbullying (aOR 2.69(CI 1.17-6.18)), and food insecurity ((aOR 1.44 (CI 1.14-1.83). Youth who perceived that they did not matter to their community were more likely to report suicidal ideation (Girls: aOR: 1.62; CI: 1.27-2.08; Boys: aOR: 1.37; (CI: 1.10-1.71)), compared to those who felt that they mattered to their community. Conclusions: Drug use, violence, and food insecurity emerged as significant risk factors for suicidal ideation among NH youth. Interventions that make youth feel that they matter to their communities may protect against suicidal ideation

The Economics of Legal Harmonization

The global legal landscape is undergoing substantial transformations, adapting to an increasingly global market economy. Differences between legal systems create obstacles to transnational commerce. Countries can reduce these legal differences through non-cooperative and cooperative adaptation processes, fostering networks of trade that link diverse legal traditions. In this article, we study the process of legal adaptation, looking at non-cooperative and cooperative solutions that can alternatively lead to legal transplantation, harmonization and unification. The presence of adaptation and switching costs renders unification extremely difficult. In the general case, cooperative solutions reduce differences to a greater extent than non-cooperative solutions, but rarely lead to complete legal unification. We consider the case of endogenous switching costs and show that when countries have the possibility to reduce their own switching costs to facilitate harmonization, they may actually choose to raise them. This may lead to the paradox that countries engaging in cooperative harmonization end up with less harmonization than those that pursued non-cooperative strategies. This explains why differences are often bridged by private codifications and by the evolving norms of the lex mercatoria.Legal Harmonization, Legal Transplantation, Transnational Contracts, Legal Change,

Inexpressive Law

According to expressive law theories, expression of values is an important function played by the law. Expressive laws affect behavior, not by threatening sanctions or promising rewards, but by changing individual preferences and tastes and, in some cases, by affecting social norms and values. New laws, however, can run against sticky social norms, failing to achieve their expressive effects. By developing a dynamic model, in this paper we show that inexpressive laws (laws whose expressive function is undermined by sticky norms) can not only be ineffective but can push the values of society away from those expressed by the law. We study the effects of legal intervention on the values shared by members of society, considering the feedback effects between laws and social norms. Just like expressive laws can foster consensus in heterogeneous groups, inexpressive laws can create a social divide, even in previously homogeneous societies.Social Norms, Countervailing Effect, Expressive Law, Civil Disobedience

Legend of Freedom: Rethinking the Role of Robert the Bruce in Shaping the Scottish Identity

This paper explores the link between King Robert the Bruce and the evolution of the Scottish nation in the early fourteenth century. While many Scottish people today, and in the centuries since his life, believed that Bruce was the primary driving force of a consolidation of the Scottish nation and its independence, this paper will show that Bruce was only able to succeed to his position as monarch and to gain recognition of Scotland as a sovereign kingdom due to the actions of earlier peoples. Specifically, I examine the foundations of Christianity within Scotland and how the Church’s insistence to be independent from the English bishoprics set the initial ideas of an independent Scotland. I also examine the few Scottish monarchs who shirked the tradition of swearing allegiance to the English king as a matter of proclaiming their sovereignty. Rather than entirely eschewing his achievements, the paper highlights the fact that Bruce was a shrewd politician who was able to expertly weave pieces of earlier precedents to strengthen his relatively weak claim to kingship. My thesis argues that Bruce’s more unsavory actions—such as the murder of his primary competitor for the throne and his penchant for siding against the Scots alongside the English just prior to his reign—were calculated and necessary steps for the ultimate success of the country rather than the chaotic choices made by a power-hungry madman. Most significantly, my paper shows that Bruce was not a “Great Man of History” but rather the beneficiary of being the right man at the right time and place

Linking Environment and Economy

River Stewards demonstrates the correlation of environment and economy. Through the Dayton Riverfront Master Plan, we saw how development focused on enhancing current environmental assets can reinforce positive economic development. Firsthand, we have visited organizations that connect environment and economy. Some provide environmental public and private services. Some focus on advocacy and education. Both rely on economic conditions to exist, while contributing to the economy. An environmental business can add growth to the economy, and a growing economy can finance more environmental initiatives
