Data fusion analysis applied to different climate change models: An application to the energy consumptions of a building office
2019
Abstract The paper aims to achieve the modelling of climate change effects on heating and cooling in the building sector, through the use of the available Intergovernmental Panel on Climate Change forecasted data. Data from several different climate models will be fused with regards to mean air temperature, wind speed and horizontal solar radiation. Several climatic models data were analysed ranging from January 2006 to December 2100. Rather than considering each model in isolation, we propose a data fusion approach for providing a robust combined model for morphing an existing weather data file. The final aim is simulating future energy use for heating and cooling of a reference building a…
Net Zeb case studies. Leaf House
2015
In this book, accomplished international experts present advanced modeling techniques as well as in-depth case studies meant to lead designers towards the optimal use of simulation tools for the design of net-zero energy buildings (Net ZEBs). The book discusses different design processes and tools used in designing Net ZEBs, starting from the fundamental concepts, design strategies, and technologies. These processes and tools are then evaluated by referring to four diverse Net ZEBs where the authors were intimately involved from the design concept to operation. The high resolution measured performance data from these case studies are compared with the predictions made using the respective d…
Towards the Environmental Sustainability of the Construction Sector: Life Cycle Environmental Impacts of Buildings Retrofit
2022
In the context of the need for carbon emissions reduction, the buildingsector, as one of the most energy intensive one, needs tools and approaches towards carbon neutrality and the increase of the buildings overall energy performances. The paper proposes an integrated approach towards the environmental performances analysis of a small neighborhood having as goal the achievement of the Positive Energy District target and the assessment of its environmental impacts. The methodology proposed includes building modeling and dynamic energy simulation using the Energy Plus engine and a simplified Life Cycle Assessment approach. Two scenarios are investigated: i) the existing neighborhood, ii) the …
Fifty Years of PMV Model: Reliability, Implementation and Design of Software for Its Calculation
2019
In most countries, PMV is the reference index for the assessment of thermal comfort conditions in mechanically conditioned environments. It is also the basis to settle input values of the operative temperature for heating and cooling load calculations, sizing of equipment, and energy calculations according to EN 16798-1 and 16798-2 Standards. Over the years, great effort has been spent to study the reliability of PMV, whereas few investigations were addressed to its calculation. To study this issue, the most significant apps devoted to its calculation have been compared with a reference software compliant with EN ISO 7730 and the well-known ASHRAE Thermal Comfort Tool. It has been revealed …
Representation of thermal building simulation in virtual reality for sustainable building
2014
The importance of energy efficiency as well as integration of advances in sustainable buildingdesign and VR technology have lead this research to focus on thermal simulation results visualized in avirtual environment (VE). The emphasis is on the representation of thermal building simulation (TBS)results and on the perception of thermal data simulated in a VE. The current application of the designprocess through energy efficiency in VR systems is limited mostly to building performance predictionsand design review, as the issue of the data formats and the workflow used for 3D modeling, thermalcalculation and VR visualization.Different applications and tools involved to represent TBS in VE are…

The Role of Natural Ventilative Cooling in NZE Temporary and Emergency Shelters Design: a Mediterranean Case Study
2016
The paper presents a case-study of a pre-fabricated housing module built in Messina (Sicily, Italy) and the assessment of its energy performances under the net zero energy perspective. The potential of ventilative natural cooling application in the case-study is also investigated. Some particular features of the building - the modularity, the prefabrication, the rapidity of assembly, the possibility of being built on disconnected soils and the absence of maintenance - identify an effective use as a temporary housing solution for e.g. workers in proximity of an isolated working place or in emergency situations such as earthquakes and natural disasters. Monitoring studies were performed durin…
A new approach to model the effect of climate change on the building sector: A climate models data fusion
2020
Several climate models have been developed and used to forecast the effects of the climate changes, however the variability of results due to different models lead to a significant uncertainty on the estimation of the building energy use for the next century. In this context, the paper analyses this uncertainty and combines different climate models in order to improve the robustness of energy consumption predictions. The data of the climate models were then used to generate hourly weather files for the future period 2020-2099 and energy simulations for a case study located in Palermo (Italy) were performed. Results show a wide variability among all models (either alone or combined with our …
LIFE CYCLE ASSESSMENT OF SOLAR COMMUNITIES: A SCENARIO ANALYSIS
The study proposes the comparisonof the life cycle performances of two different energy systems aimed at covering the needs of a large mixed-mode community, in Calgary (Canada). The two systems investigated are a“conventional” one, using heat pumps for heating, cooling and domestic hot water, and another one widely deploying solar thermal panels as well as a district heating infrastructure and a borehole seasonal thermal storage. The analysis is based on the LifeCycle Assessment (LCA) methodology and includes the stages of raw materials and energy supply, system manufacturing, use stage of the systems, generation and use of energy on-site, maintenance and components’ substitution, and explo…
