New Building Typologies for Zero Energy Mass Custom Housing(ZEMCH)in More Sustainable Patterns of Development

Conferences and publications on Smart Cities and self-styled ecological buildings such as“Vertical Forests”,“Biophilic”building complexes and other similar are multiplying.But then,in reality,we continue to design as we have always done for the last ninety years:with the consolidated rules and formal solutions of international post-modern composition,in its various forms.The only attentions are(and not always)to super-insulate the envelopes,arrange photovoltaic panels on the roofs,make the systems smart and cover the facades and roofs with appropriate green washing.Even in the awareness that human settlements and cities are extremely complex phenomena,mostly determined by economic and social factors,rather than by conscious typological-settlement choices,perhaps the time has come to acknowledge that the traditional paradigms of design must be changed.First of all,the types of settlements must be renewed,because it is through their optimization that the greatest savings in terms of energy and sustainability can be achieved.The research presented here is the application of a ten-year study that involved the development of net Zero Energy Mass Custom Housing(ZEMCH)in specific context in southern Italy.The Innovation and Transparency of Tenders Environmental Compatibility(ITACA)Assessment Protocol,derived from the Green Building Challenge’s GBTool,was used as a design guide,which is normally used for the assessment and judgment of sustainability at the building scale and not of the urban design.The result is a settlement model in which network of pedestrian,cycle and public transport is fully integrated with adjacent urban areas;effective landscaping connects public and private green and kitchen-gardens/orchards everywhere;buildings are made with new semi-underground typologies;net ZEMCHs are made with local,recyclable materials with low impact or positive energy balance;wastewater and rainwater are collected,in-loco phyto-purified and reused;renewable energies(sun,earth,wind)satisfy remaining necessities,with a minimum of plant interventions.

The Contributions of Building Information Modelling to Sustainable Construction

Global concerns toward environmental issues have induced growing demand for new approaches in the construction because of its considerable impact on the environment and use of natural resources. Through using construction sustainability tools, methods and techniques, a greener design can be applied during various building phases. In this connection, it is argued that the analytical and integrated models applied by Building Information Modelling (BIM) may also facilitate this process to be performed more efficiently. BIM and construction sustainability are quite different initiatives, but both have received much attention in recent years in the architecture, engineering and construction (AEC) industry. A rigorous analysis of the interactions between them implies that a synergy exists which, if properly it is understood that can be helpful to reduce the environmental impacts of the AEC industry. A BIM-based design model can contribute to sustainability through its three main dimensions which are environmental, economic and social. In this paper, by reviewing the existing literature on BIM and construction sustainability and using a matrix to analyze construction sustainability dimensions and BIM functionalities a number of interactions have been discussed. It can be concluded that despite there are many improvements in implementation of BIM in environmental and economic aspects of sustainability, its potential impact on social dimension has not been explicitly explored hence further studies need to be undertaken in this area.

Zero Energy Hotels and Sustainable Mobility in the Islands of Aegean Sea (Greece)

The goal of this work is to evaluate and to give evidence to innovative and sustainable technologies applied in the construction industry to carry out self-sufficient energy and to use the surplus energy for the production of hydrogen vector. An architectural integration design along with high technological systems is performed. The intermittency of renewable energy sources along with climatic conditions dependency imposes to store the energy produced, since it is clean and having a big calorific value: the hydrogen vector is currently the better energy carrier. The energy to obtain hydrogen by dissociation of water is supplied by a photovoltaic (PV) system. Through the computations of the annual energy balance between building’s demand and supply energy, it is shown that the extra energy produced by the solar generation system is used also for the hydrogen sustainable mobility. The renewable systems, model’s design and case study are tackled for the bigger one of the Dodecanese islands in the South Aegean Sea: Rhodes (Rodos). The Zero energy building’s integrative design-based approach, applied to the Hotel Buildings type industry is targeted to have new hotels buildings, in the Mediterranean typical warm climate, with zero energy consumption. The designers, authors of this work, have studied a real case or pilot project of an hotel, in the resort formula, suitable to the Greek landscape, showcasing technologies and innovations supporting environmental sustainability, energy efficiency, use of renewable energy, electricity storage by fuel cells that are tools particularly applicable to hotel facility [1]. The feasibility of this case study or pilot project is aligned jointly to the target of Zero Emission and Energy Efficiency EU Policy, as imposed by EU Directives. The strategic position of Rhodes in a geographical point full of sun and wind renewable energy power, enables to ensure the clean energy production, the current interesting development of the hydrogen as energy vector in the buildings [2] and also to satisfy the demand of tourists’ accommodation by having at the same time zero energy costs. Moreover, the presence in the island of the best example worldwide of ancient and sustainable built environment (UNESCO World Heritage site), represents also the best motivation to give witness there of a zero impact environmental urban development through the adoption of these achieved scientific results for a major success of Zero Energy Buildings.

Analysis of Thermal Behavior of Materials in the Building Envelope Using Building Information Modeling (BIM)—A Case Study Approach

Building envelope is a fence that controls heat exchange between interior and exterior and plays an essential role in providing thermal comfort conditions of residents. In recent years, due to the necessity of conserving energy and also preventing increased environmental pollution, the importance of sustainable construction has been doubled. Checking the problems of thermal behavior of the building envelope materials, and what influences in the heating and cooling loads exerted and energy consumption of buildings, are the questions that this research seeks to answer. In this regard, building information modelling analysis (BIM) has worthy contribution in the completion process of sustainable design;thus using software Design Builder, it is paid attention to simulation of the thermal behavior of two types of defined materials for the building envelope that was designed as a Research Institute of Renewable Energy of Yazd University. For Type 1 materials, two layers of brick have been selected, and for Type 2 a thermal insulation layer also added it. Results of the analysis showed that the use of materials Type 2 in the cooling load %4.8 and in the thermal load %62.5 reduction can be achieved which means reducing the load on active system and thus reducing the initial cost of building. Also reduction in annual energy consumption by almost %2.4 for cooling and %62.9 for heating buildings have been achieved, which makes saving non-renewable energy consumption, and consequently reducing environmental pollution as well as reducing current costs will be established.

Integrated landscape approaches to building resilience and multifunctionality in the Kailash Sacred Landscape,China

Climate warming-induced rangeland degradation in arid and semiarid steppe imposes substantial threats to the livelihoods of people.But this dilemma can be solved by combining all sectors of agriculture,animal husbandry and tourism through their complementarity,i.e.by adopting integrated landscape ecosystem-based approaches.A number of experiences and lessons have been achieved in a specific sector for its successful development,but not in the multiple social,economic,and ecological systems.In this study,we use the perspective of integrated ecosystem management to strengthen crop-livestock integration and innovative livelihoods,and propose a multifunctional Kailash Landscape to activate the inter-linkage among agriculture,animal husbandry,and heritage pilgrimage/tourism in order to achieve multiple functions of the socio-ecological system.A case study of Kailash Sacred Landscape Conservation and Development Initiative in China was quantitatively and qualitatively analyzed by land use and land cover change and their consequences on multiple ecosystem services.Integrated landscape management was found to be effective in building resilience of socio-ecosystems by reducing the vulnerability of traditional agriculture in terms of improving crop production and animal husbandry.A multifunctional landscape is expected to be integrated and build a resilient sector complementarity including farming,pastorism,environmental and socioeconomic function.The analyses show that integrated landscape approaches provide an effective perspective for sustainable socio-economic development in this sacred landscape.The findings highlight the importance of landscape-scale ecosystem-based adaptation to environment change.
