Studies Energy Efficiency of the Renewable Sources use Considering Climate in Latvia
2015
AbstractThe paper discusses problems of energy supply of buildings using renewable sources given the local climatic conditions. The meteorological conditions in Latvia and Riga for last year were analyzed. In paper shows examples of energy efficient buildings allowing that to provide comfort temperature and indoor air quality. The structure and composition of local building materials, providing good thermal insulation are described. The heating systems for test buildings using renewable energy sources were investigated. The assessment of the energy efficiency of the “air-air” and “air-water” heat pumps is studied.
Experimental Research of Thermal Comfort Conditions in Small Test Buildings with Different Types of Heating
2015
Abstract The aim of this study is detailed analysis of long-term monitoring data of thermal comfort conditions and energy efficiency in small test buildings equipped with different heating systems. Calculations of PPD index and local thermal discomfort factors are provided for the test buildings during three weeks of heating season. It is shown that the type of heating system has influence not only on heating energy need, but also on thermal comfort conditions in the room.
Assessing the effectiveness of green roofs in enhancing the energy and indoor comfort resilience of urban buildings to climate change: Methodology pr…
2021
Abstract The effects of climate change on the built environment represents an important research challenge. Today, green roofs (GRs) represent a viable solution for enhancing energy and urban resilience in the face of climate change, as they can have a positive impact on the building's indoor thermal comfort and energy demand, as well as inducing various environmental benefits (easing urban heat island effects, improving the management of runoff water, reducing air pollution, etc.). Thus, it is important to be able to assess their effectiveness, both today and under future climate conditions, in order to evaluate whether they can also provide a valid long-term solution. In this paper, a sim…
Towards Nearly Zero Energy and Environmentally Sustainable Agritourisms: The Effectiveness of the Application of the European Ecolabel Brand
2020
Tourism represents an important economic driver in Italy, being responsible for approximately 13.2% of the total GDP (a value higher than the reference European average) and for nearly 10% of the regional GDP. Among the touristic sectors, the agritourist ones show a persistent growth, experiencing in 2019 a 6.7 point percentage improvement compared to the 2017 figures. Given this situation, the transition towards a low-carbon path, affecting the building sector for some time, should also involve agritourist buildings, through the release of EU directives, member state laws, and technical rules. On the other hand, agritourism sites could be awarded the Community EU Ecolabel. Unfortunately, a…
L’Aula Magna dell'Università di Palermo: cronistoria di un cantiere decorativo (1928-1938)
2020
Situata all'interno dell'odierno Dipartimento di Giurisprudenza, l'Aula Magna dell'Università di Palermo è stata progettata dall'architetto Antonio Zanca che firma nel 1929 il progetto esecutivo di un ambiente neo-settecentesco dotato di mobilio e decorazioni pittoriche sulle pareti. Nel 1934 è stato indetto un concorso nazionale per l'affidamento delle decorazioni pittoriche vinto da Arduino Angelucci e Manlio Giarrizzo cui spettano rispettivamente la volta e le pareti. Grazie alla stampa locale è possibile ricostruire - almeno in parte - le vicende di questo concorso che si colloca in un contesto nazionale fortemente attento, dopo la Triennale di Milano del 1933, al problema della decoraz…
A Review of Key Performance Indicators for Building Flexibility Quantification to Support the Clean Energy Transition
2021
The transition to a sustainable society and a carbon-neutral economy by 2050 requires extensive deployment of renewable energy sources that, due to the aleatority and non-programmability of most of them, may seriously affect the stability of existing power grids. In this context, buildings are increasingly being seen as a potential source of energy flexibility for the power grid. In literature, key performance indicators, allowing different aspects of the load management, are used to investigate buildings’ energy flexibility. The paper reviews existing indicators developed in the context of theoretical, experimental and numerical studies on flexible buildings, outlining the current status a…
Investigation of design strategies and quantification of energy flexibility in buildings: A case-study in southern Italy
2021
Abstract The need for nearly (net) zero energy buildings in the current European landscape does not merely refer to energy balances: the aim to investigate the interaction between generation and load and find sources of technical-economic energy efficiency is marking the rise in interest throughout research and practice of energy flexibility solutions in buildings. In this regard, the study aims at enhancing the energy flexibility of a building in southern Italy through Rule-Based Control algorithms for the control of the space heating system and the charge and discharge of an electricity storage. The influence of electricity pricing and the thermal comfort conditions on flexibility is also…
Tra medioevo e prima età moderna: eclettismi nel Mediterraneo : Ecclettismo consapevole: alcuni casi di approfondimento.
2019
Coexistence and mixture phenomena of different architectural idioms in the early 1500s Sicily are not rare. The present essay evaluates two late Gothic masters, Antonio Belguardo and Girolamo Vicchiuzzo (his epigone), whose activity in Palermo and Alcamo protracts in various and "eclectic" buildings, which go beyond the first half of the XVIth century.
A Possible Approach to Take into Account the Presence of Green Roofs in the Energy Certification of Buildings

Sistemi costruttivi tradizionali in gesso nell’architettura siciliana
2020
Chalks outcrops characterize all the central-western territory in Sicily. They are different in types and extension and tangibly mark the presence of the well-known sulphurus chalky series. In the same areas it is possible to see several traditional buildings built, even in their structures, using gypsum, an material which is unusual in other contexts. In some cases the chalk outcrop makes up even the base of a building. This text describes different kinds of walls, floors, vaults and flooring where gypsum is the main material.
