The need to fight the global climate change in recent years impose to designers and planners to adopt strategies, technologies and methods that enable to focus on smart developments also in restrained conditions like in protected historical small villages. This essay shows multidisciplinary results obtained by using both the building information modelling (BIM) and innovative approaches for design a highly energy efficient Hotel building that can represent a valuable attraction for the touristic demand of the village. In wider perspective, it will be firstly introduces an ongoing strategy of regional energy efficiency and tourist development which is under discussion by a network of small Lucanian villages in South of Italy.Integrated project delivery (IPD) and design optimization are the most benefits coming by BIM-collaborative methods. Many practical implications are coming from the implementation of BIM, like the high energy performance goal of the building, the reduction of extra costs of design changes during the subsequent phases of construction process. Accurated digital 3D models improve collaboration between project parties, to ensure that the project is well-coordinated before the construction phase begins. This paper investigates also the contribution of dyanmic energy analyses to design the hotel and their influence on the final architectural solutions, and aimed to become a real development model for a network of small villages..

The aim of this paper is to present the multidisciplinary design process developed for a research on recent residential buildings in Northern Italy. The novelty of the approach is the concrete application on case studies of holistic analysis process. The multidisciplinary team, composed by urban planners, architectural designers, and experts in energy-efficiency techniques, has examined two buildings preventively designed under the Biocasa protocol of a cooperative company active in Northern Italy. The aim of the project was to identify an integrated procedure to increase the environmental quality (specifically in term of energy efficiency) of these houses. The research was articulated in three levels: 1. Urban, 2. Architectural, 3. Technological. The plan was to investigate alternative designs for the buildings proposed by the cooperative developer, driving the design towards the realization of climate-sensitive buildings: minimizing the negative effects on the climate using the smallest amount of resources and energy and, at the same time, making maximum use of the positive 12 Maserai, Grecchii, Malighettii, Palazzoii and Sesana effects, such as the sun, to create a "healthy" interaction between indoor and outdoor climate conditions in buildings. The alternative outcomes have been compared with the original ones in order to understand and to measure the positive and negative effects, using the tools: CENED (steady-state) and TRNSYS for the estimation of energy consumption and ECOTECT for daylight analyses. The parameters considered for the alternative projects belong to different fields: environmental at urban scale (wind, solar exposure, orientation, climate condition), architectural (shapes, internal layout, building types), constructive (insulation, shadows, openings, etc.), and systems (HVAC, renewable energy sources). The multidisciplinary nature of the research emphasizes the importance of the process, which integrates different disciplinary approaches, to carry out a sustainable house and to transform the generic concept of sustainability into a measurable element with some comparable pointers.
Using Building Information & Energy Modelling for Energy Efficient Designs
J. Inf. Technol. Constr., 2021
The construction industry has a huge impact on the environment in terms of noise, water and land pollution, traffic congestion and waste disposal. Another aspect of the construction industry impact on the environment is the increasing energy consumption. According to published research, buildings energy use is expected to increase by 32% by the year 2040. As a result, efforts have been directed toward improving green building awareness and the application of sustainability concepts in the design, construction and building management processes. In this research, using extensive simulations, the integration between Building Information Modeling methodology (BIM) and Building Energy Modeling (BEM) methodologies in order to effectively minimize the overall energy consumption of a residential building in the UAE is investigated by studying several design factors including: building orientation and windows type, size and distribution on the overall building energy consumption. Results sho...

Alaçatı is a densely visited unique Aegean town on the west coast of İzmir, Turkey. It has been famous after 1990, because of its authentic streets with Greek architecture, nature and culture. Since the most important pull factor of Alaçatı is to be the vernacular houses, the historical vernacular houses were converted into hotels for the accommodation and cultural experience demand of the tourists. The present study deals with the hotel that is number 68 of the 1005th street, which is converted from a 150 year old Greek house in Tokoğlu province of the historical centre of Alaçatı. The purpose of the study is to reveal the sustainable design properties that the house contains by both conceptual and quantitative aspect. Regarding to this aim, the house has been modelled by a digital energy modelling program. The architectural drawings, climate and weather data from Adnan Menderes Weather Station, materials and building usage data, and the restoration and survey works of the house have been used as the needed information for the energy model of the house. The sustainable design properties were presented on the model for the winter and summer condition respectively, as the percentage effect on the heating and cooling energy need for the hotel. As the result, it is observed that some of the passive design properties reduce the heating and cooling energy, some of them don’t have any effect and some of them are recorded to be far from being sustainable as they increase the energy need of the building. It is anticipated that the elicited results from the study are to be a guide for new buildings that are going to be designed in the area in terms of sustainable architecture.

Rapid advancement on digitalisation is changing the way buildings are planned, designed, built and managed nowadays. A collaborative computer-based environment known as Building Information Modelling (BIM) is one of the advancements introduced as a platform to boost up the efficiency of the construction industry. However, poorly designed, constructed and managed building or infrastructure contribute to environmental issues such as CO2 emissions and energy consumption. Thus, attachment of sustainability element in BIM not only increase the efficiency of the project but also can help to plan, design and construct in a more environmentally friendly way. A study on the overall energy use throughout the construction life cycle is needed to identify the most critical stages and to develop energy-reduction strategies via BIM. Thus, this paper provides an intensive review of BIM understanding, its energy analysis practices in the construction phase and existing building environmental assess...
Abstract Energy, as a concept that is consumed quickly and irresponsibly by the modern world conditions and building energy classification systems are aimed to be examined in this process. Energy-efficient building design is gaining in importance with each passing day today when environmental problems are increasing rapidly. Efficient use of energy represents reducing the amount of energy needed for same quality and standard of products and services in the form of life without sacrificing and gaining the highest level of energy to be spent on. Certification systems developed by various countries around the world, regulations and standards in the production of energy-efficient building solutions are required. Energy conservation and economic development can go hand in hand. Efficiently designed buildings will slash energy bills, liberate investment capital and avoid the expense of building new power plants. In recent years, we’ve seen real advancements in climate change issues, many of which have been directly related to the built environment. Some issues in these areas will have positive impacts on the built environment, but there is an emerging group of products, technologies, materials and design principles that seems to be taking shape in a growing number of buildings scattered across the globe. The main premise of this study is to respond to module design of three big topics integration. These are “energy-building design-technology implementation”. An understanding of those three issues is important to derive a project-based integration methodology. It should be thought that there is no single solution for energy efficiently designed buildings. The ability to apply knowledge and a process of critical judgement of all point issues should be the first steps of this approach. The methodology of understanding involves close co-ordination between the three modules based on “know-how” terminology. This terminology means applicable knowledge, formulae, technical data and information to achieve low energy architecture within the scope of this study. So informations, designs, details, methods, procedures and experiences can be defined as values that are determinants of environmental behaviour. The importance of these values is followed up in a new set of policy measures for every single type and/or condition. The frame of each country’s policy can be determined in the perspective of wealth, technological advance, energy consumption- requirement and environmental consequences. These principles can affect directly to life cycle assessment of the buildings and create sustainable consumption and thought. Keywords: Energy-efficiency, energy- building design-technology implementation, know how theory, low energy architecture

Energy efficiency in existing building stock is a priority for achieving the decarbonization objectives imposed by the European Union. Several European projects have addressed the issue and suggested strategies. In particular, the TripleA-reno project has among its objectives the development of a web tool for the energy assessment of buildings so that users can simulate the economic and energy benefits of the renovation process. The paper aims to assess the impact of simplification in geometric, energetic and modelling input on the calculation of the energy performance of buildings. The study was conducted on a case study of the TripleA-reno project, located in Concordia Sagittaria (Venice). The architectural configuration, the structural typology and the stratigraphies of the building and the interventions foreseen by the redevelopment project are described. After defining the energy modelling software intended to be used, a detailed energy assessment was carried out, which was sub...
BIM as an analysis tool supporting the reduction of buildings energy consumption
Thermophysics 2021: 26th International Meeting of Thermophysics 2021
Energy requirements for buildings are increasing-nearly zero-energy buildings (nZEB) are expected to become the standard by 2050. In order to achieve this goal, more and more often in the architectural, engineering and construction sectors, various tools are used to computerize the designing process, including programs using the BIM standard. Building Information Modeling (BIM) is a design approach based on intelligent three-dimensional building models. The article presents the possibilities of optimizing the energy consumption of buildings with the use of software designed specifically to work in the BIM framework. Using this tool, two buildings were modeled with the same cubature, but with different construction and architectural solutions. The first one is characterized by a traditional shape with a bay window based on columns, a gable roof and a vestibule, while the latter is a building with a compact, simple structure and a flat roof. The software created an energy model and generated the design options enabling the analysis of the energy demand of these buildings during the year expressed as EUI (kWh/(m 2 year)) and the Autodesk Insight cloud was used to simulate the energy processes. It was shown that with the use of the same construction materials, it is possible to reduce the energy demand of buildings by modifying the shape of the construction. In addition, analyses of energy consumption were performed depending on the material solutions used, in consequence such models were developed that allowed achieving restrictive energy requirements.
