Day 2 :
Head, Institute for Renewable Energy at Eurac Research
Wolfram Sparber is heading the Institute for Renewable Energy at Eurac Research since it’s foundation in 2005. Eurac Research is an applied research centre located in Bolzano-Northern Italy. Since 2011 he is vice president of the European Technology and Innovation Platform for Renewable Heating and Cooling (ETIP RHC). Since 2016 he is chairman of the board of directors of the North Italian energy utility Alperia. Alperia is one of the largest renewable energy producers in Italy, and has a special focus on sustainable energy solutions. Wolfram Sparber studied applied physics at Graz University of Technology and Universitat Autonoma de Barcelona.
Many countries and regions in Europe and world wide have set ambitous climate and renewable energy targets to be met til 2020, 2030 and 2050. But with which energy system can such targets be met? What technology combination, to which extend, has to be applied to reach the target in a most cost effective way? Can the targets be reached considering technical, social, environmental and economic constraints? Within Eurac Research a method has been developed, that allows the modellers to give answers to these questions considering the hour by hour energy consumption for a referenece year. The North-Italian region of Southtyrol with its energy consumption, building stock, landscape and natural resources, transportation mix and its climate plan (target 1.5 ton CO2 emissions / capita till 2050) has been taken as a demo model. Technical, social and environmental constraints have been considered with regards to the possible expansion of renewable energy sources for electricity and heat production. The energy efficiency potential has been considered, especially with regard to the existing building stock. Therefore a detailed building clusterisation has been carried out with regard to building type, year of construction, applied construction technologies and possible refurbishment interventions and the related investment cost. Further more the mobility sector and its transition to zero emission transport has been considered. The energy model shows that the target can be reached with a series of measures based on today existing technologies. Considering the cost, not only the target scenarios are not more expensive than todays energy system, but especially a very relevant cost part is shifted from fossil fuels in local investment in energy efficiency and technology development; leading to an important push for the local economy. The model can be applied to other regions and countries.

Annarita Salladini is a Project Manager currently working for Processi Innovativi, an engineering company owned by KT-Kinetics Technology (Rome, Italy). She received M.Sc. in Chemical Engineering and Ph.D. both from the University of L’Aquila (Italy). She joined Processi Innovativi on 2009 and since then she was involved in R&D project and Engineering Project focused on hydrogen production, renewable energy exploitation, waste conversion processes. Since 2011 she is tutor assistant at the University Campus Biomedico of Rome in the field of Analysis and Simulation of industrial chemical processes. She co-authored several scientific papers in refereed journals and chapters on international books.
With the increasing of population, waste management is becoming more and more a serious problem. The conversion of municipal solid wastes into a valuable and large consumer product could be a successful strategy. On this scenario the waste to bio-methanol route may be a valid alternative to a WtE concept, providing not only an effective waste disposal system but also contributing to the reduction of the greenhouse gases (GHG) emission. The proposed technology infact may account for a reduction of GHG emission up to 54% if compared to waste incinerator and conventional methanol production systems. Main steps involved in this conversion process include high temperature RDF gasification, syngas purification treatment and conditioning up to methanol synthesis. The strength of the proposed technology is enclosed in the gasification method itself, where the adopted operating conditions avoid any production of toxic substances. Moreover the produced syngas is synthesized into methanol molecule and any discharge to the chimney is avoided. When no other external sources are involved, about 50% of the carbon incoming with waste is fixed into methanol product with a synthesis conversion ratio equal to 2.4 ton of RDF per Ton of methanol. The resulted purified biofuel-grade methanol could impact on the market with about 450 €/ton price by exploiting the double counting directive, making it more catching in a bio-fuel economic view. The techno-economic analysis showed that the proposed technology is a valuable and sustainable example of a circular economy, approaching the target of a zero-emission plant.
Politecnico di Milan
Keynote: Sustainable Architecture in Italy: An overview on green architecture according to LEED Protocols
Time : 09:30-10:00
Giuliano Dall’O’ is an Associate professor in Buildings Physics at Politecnico di Milan and an expert and consultant in many areas relevant to energy conservation, energy efficiency and the use of renewable energies in buildings. In the areas relevant to energy certification of buildings Giuliano is one of the leading experts at national (Italian) but also European level. Giuliano is an expert, in the professional field, in the following subjects: Energy and Sustainable Planning, Sustainable Energy Action PLan, Energy Certificationof Buildings, Energy Audit and Green Energy Audit of Buildings, Zero Energy Building Design and LEED Certification.
In recent years, green architecture is spreading around the world, reflecting a more conscious approach to sustainability by architects but also by the real estate market. Although the market growth of green buildings in many cases it is not fast, the feeling is that we have passed a point of no return and that green architecture is no longer considered experimental architecture, but a practice that is consolidating. The introduction and dissemination of international environmental certification protocols such as LEED has certainly helped to steer the market towards building recognizable models in which performance can be measured and/or evaluated on the basis of uniform criteria. The Protocols, however, necessarily introducing the elements of rigidity could modify the architectural choices, in other words, they may contaminate the Architecture of buildings. Contamination may be positive, if a certi cation protocol triggers a more environmentally-focused design, but it may also be negative, if said protocol becomes a constraint contributing to “globalizing” Architecture. The answer to the aforementioned dilemma, nurturing the cultural debate of the last decade, may only be found if one analyzes buildings through a study of the case studies of green buildings built in a certain period. The study presented in this paper is the result of a synthesis of research conducted on buildings LEED certified or undergoing certification in Italy. Of about 300 buildings that are found in this situation, 30 are analyzed in depth also from the technical point of view. The added value of this study has been the analysis of said buildings based on sustainability, allowing to look at architecture from what we consider to be a privileged point of observation.
