impact of renewable energy technologies on the embodied and operational ghg emissions of a Nearly zero energy Building
Journal of building engineering, 2019Co-Authors: Sirje Vares, Tarja Hakkinen, Jaakko Ketomaki, Jari Shemeikka, Nusrat JungAbstract:Abstract The renewable energy solutions are being actively applied to achieve Nearly and net zero energy Buildings, however very few studies have reported the environmental impact of applied renewable energy sources (RES) on a net zero energy Building from the perspective of both embodied and operational greenhouse gas emissions (GHG). As the energy performance of Buildings improves, the significance of embodied energy and embodied greenhouse gases increases when compared to the operational impacts. These trends can become more important when the technology for net zero energy and off-grid Buildings is being advanced especially when necessitating use of energy storage (batteries). The aim of this study is to advance new knowledge on the impact of local renewable energy solutions on the GHGs of Nearly zero energy Buildings by considering both operational and embodied impacts. This study presents the case study of a net zero residential Building and evaluates three main cases of annual net zero electricity ( Case 1 ), off-grid electricity ( Case 2 ) and 100% solar thermal heat ( Case 3 ) and in total presenting six variations of Building integrated RES technologies. The results indicate that the embodied GHG impacts are responsible for two thirds of GHG impacts which is opposite when compared to an Nearly zero energy Building that is connected to the grid and district heat network (BAU case). When RES technologies are integrated with the Building and electricity is produced from renewable sources the ‘Annually net zero electricity’ case produces almost 40% less GHG emissions when compared to the ‘BAU’ case. For the ‘off grid electricity’ case using Li-ion batteries for seasonal energy storage, resulted in the highest embodied GHG emissions due to immature technology.

Numerical analysis of phase change materials for optimizing the energy balance of a Nearly zero energy Building
Sustainable Cities and Society, 2020Co-Authors: Rosa Francesca De Masi, Antonio Gigante, Giuseppe Peter VanoliAbstract:Abstract Phase change materials receive increasing attention for their potential to make Building environmentally sustainable and to reduce the overheating problem. Quantitative results are needed for understanding the incidence on the energy balance of low consumption Buildings and for estimating the possible increment of renewable energy self-consumptions. With this aim, by means of a multi-stage approach, the optimal configuration for microencapsulated materials integration in term of melting properties, thickness and position is discussed. It is considered the application of different management strategies for the heating and cooling system and the variability of weather conditions. The influence of insulation type and back wall technology is also explored. The results for the case study, a single-family home already certified as Nearly zero energy Building, highlights the potentialities in term of reduction of the cooling demand for Mediterranean and Continental climate but also the penalty due to reduction of solar gain during the winter.

on the refurbishment of the public Building stock toward the Nearly zero energy target two italian case studies
Energy Procedia, 2016Co-Authors: Vincenzo Corrado, Giovanni Murano, Simona Angela Alina Paduos, G RivaAbstract:Abstract The study presents some results of the on-going European Project, RePublic_ZEB, on the refurbishment of the public Building stock towards Nearly Zero Energy Building (nZEB). The work is focused on the application of the nZEB requirements to two existing public Buildings representative of the 1960s in Northern Italy. Many packages of energy efficiency measures that comply with nZEB requirements are identified and evaluated. The aim is to promote energy efficient but also cost-effective solutions for the Italian Building stock refurbishment. The results are presented in terms of «package of measures», energy consumption, global costs, actualized pay-back period and CO 2 emission.

a new procedure of energy audit and cost analysis for the transformation of a school into a Nearly zero energy Building
Energy Procedia, 2017Co-Authors: Vincenzo Corrado, Simona Angela Alina Paduos, Ilaria Ballarini, Lidia TulipanoAbstract:Abstract The article presents the fundamental steps of Building refurbishment toward the nZEB target; it is based on a detailed energy audit and on a financial analysis. The methodology starts from the set-up of a numerical model of the Building, calibrated through actual data on operation, climate and energy consumption. Then, a cost-optimisation procedure is applied to identify the energy efficiency measures that determine the minimum global cost in 30 years lifetime. Finally, the measures are improved as to comply with the nZEB requirements and to be cost-effective as well. The methodology was applied to a high school in Torino.
