    Designing buildings with high environmental and economic efficiency has recently become very difficult, and the ecological problems of the whole world have become realistic and require radical solutions. As 20 - 60% of the total energy used in buildings is affected in their enclosures design and construction, consider adopting sustainable energy efficiency strategies in their design and construction. In the past, factors such as society, economy, and technology influenced architecture, prompting architects to develop innovative design theories, particularly after the industrial revolution and the devastation it left in the environment, such as pollution and natural resource consumption, as well as the phenomenon of heat islands. In addition, many factors such as society, economy, and technology led to the idea of active adaptive smart buildings emerged as these factors have provided technological advances in electrical control systems, computer engineering, information technology, artificial intelligence, electronic science and materials science, opportunities for the use of motor building systems in architecture and its components. Therefore, it introduced the concept of active, interactive, moving and adaptive facades instead of the traditional fixed facades, which are characterised by interacting with the surrounding environment through many technologies that improve the economic and internal environment of the building and its efficiency to make the building sustainable. CABS work with the concepts of adaptability, versatility, and evolution. This paper aims to provide a comprehensive review of the research, design and development efforts in the CABS system field. Based on the study of the theoretical framework, a classification is made to place a variety of concepts in one context. Thus, a measurement ruler is reached that includes an essential vocabulary and indicators that can characterise the CABS so that the research can measure its level of effectiveness in the examples selected. Keywords: adaptive facades, CABS, economic efficiency, environmental efficiency, adaptability, sustainable energy. DOI: 10.7176/JETP/12-2-06 Publication date: July 30th 202

    This master thesis aims to develop a methodology to identify the optimal operation of different HVAC system configurations for different climate conditions and building typologies. To reach the objective, the work is carried out in three main steps using dedicated tools (DesignBuilder, EnergyPlus, and eppy script (python language)) and running co-simulation. In addition, the nZEB standard established by the most recent edition of the Spanish Technical Building Code is addressed in this study through a parametric optimization study of a reference building. The effectiveness of this legislation is evaluated in terms of its capacity to disseminate the idea of building energy cost optimization and reduce the annual energy consumption in the residential sector. To this end, a reference building was designed and multiple HVAC designs were evaluated using DesignBuilder building energy simulation software and found the best optimization of HVAC solutions through EnergyPlus and eppy. In total, a set of 30 alternative scenarios was established and parametrically evaluated for 5 cities representing the 5 climatic zones of inland Spain (Bilbao, Burgos, Seville, Madrid, and Almeria) resulting in 150 simulations. The results were evaluated utilizing annual energy consumption (electricity, natural gas, and other fuels) values concerning the calibration of set point manager temperature (heating), obtaining the cost-optimal and minimum consumption levels of annual energy. It is worth mentioning that this study is mainly concentrating on the Energy Supply System (ESS), where the Energy Saving Measure (ESM) is kept unchanged, which should be reviewed in future updates

    Climate change is a threat and crisis that hit the world today; one of them is causing drought, rising sea levels, melting polar ice, and heat waves; therefore, the target towards Net Zero Emission (NZE) in 2060 must be an obligation in all countries. Green Building (GB) is a building that meets Building Technical Standards, and has demonstrated demonstrable success in conserving resources such as water, energy, and other resources. The application of GB principles following the function and classification in every stage of their implementation is expected to reduce greenhouse gas emissions. This research aims to analyze the cost of improvement work based on GB assessment in applying the Technical Guidelines from Minister of Public Works and Public Housing (PUPR) No. 1 of 2022, which is the latest regulation in Indonesia. The blockchain-BIM method and the implementation of the GB component will be analyzed using Structural Equation Modeling-Partial Least Squares (SEM-PLS) to find the most influential factors. The results of this study show that by applying Blockchain-BIM to overcome the cost constraints, it is proven to be able to increase the cost performance of GB in modern shopping center buildings by 3–3.8% in the Basic rating, while for other ratings, it is 0.5–2.1% higher, where the selection of a renewable energy model is very influential. Doi: 10.28991/CEJ-2023-09-10-09 Full Text: PD

    Comparative analysis of sustainable building certification tools: application for the development of a sustainable, rehabilitation profile

    Get PDF
    General Objective Develop a Profile that defines criteria, steps and procedures to rehabilitate a building with environmental objectives, and that may be used as an assessment tool to achieve a certification for sustainable rehabilitation. Specific Objective Analyze the differences and relationships between the assessment for new constructions and the assessment for existing buildings of each of the defined certifying tools.A big percentage of the environmental impacts caused by industry come from the construction sector. In Spain almost 30% of the total CO2 emissions come from the use of residential and non-residential buildings. Apart from the energy and water consumption of the operational stage of the building, the resource extraction and material manufacture stages must also be considered, as they represent between 25-30% of the total energy consumption of the building’s life cycle1. Therefore a building as a single body represents a great impact in the environment, the amount of resources consumed and waste produced are excessive and, without any doubt, unsustainable. Under these considerations, this investigation intends to define the rehabilitation of buildings as an answer to address environmental impact. By optimizing management, organization and improving the physical performance of the stock of existing buildings, the rehabilitation with environmental goals embraces the possibilities of transforming the construction sector, by giving way to the concept of re-use and recycle and encouraging these answers in order to recover resources from existing structures instead of extracting them, and improving the buildings operation and management to increase its life cycle performance. But rehabilitating a building is not a simple process. Many factors must be taken into account especially when the building is operating. Certifying tools for sustainable buildings give the guidance, through a list of criteria, to accomplish a level of sustainable efficiency in the building, for either new construction or existing buildings. The certifying tools for existing buildings have been developed to assess their current performance in operation and maintenance, and the potential they have to improve. The certifying tool for new constructions guides the building from the design stage to the construction stage to accomplish a physical and inherit sustainable performance. By analyzing and comparing both types of assessment tools and from different organizations (LEED and BREEAM), it is intended with this work to develop a tool that will not only certify a rehabilitated building, but will also shows the steps, the criteria and procedures for a Sustainable Rehabilitation
