Effect on Energy use Due to Different Orientation: A Case Study of Commercial Building
GRD Journals, 2019
Building requires energy in their life cycle from its construction work to demolition work. Studies on the total energy use during the life cycle of buildings are desirable to recognize phases of largest energy use and to develop strategies for its reduction. In the present paper, a review of the life cycle energy analysis of building is presented. The aim of this paper is to present an energy analysis by using building information modelling (BIM). The Building Information Modelling (BIM) software is used for the design of wide range of constructions; from small house to big apartment buildings. This program allow the architect, designer or civil consultant to perform several simulations of the energy behavior of a building in a timely manner, even before a single brick is put in place The study includes energy analysis of commercial building and the comparison of energy analysis data at different degree orientation. Building's life cycle energy demand can be reduced by reducing its operating energy through use of passive and active technologies even if it leads to a slight increase in embodied energy. It is observed that low energy buildings perform better than self-sufficient (zero operating energy) buildings in the life cycle context.
Buildings Orientation and its Impact on the Energy Consumption
The Academic Research Community Publication, 2018
Nowadays, many countries suffer from severe shortage of energy resources and the inability of saving it. It is necessary to develop an integrated strategy, to make buildings consume less energy and to integrate active and passive design techniques. Since the building orientation is one of the most important factors affecting energy consumption, this paper addresses the effect of building orientation on the amount of energy consumption within buildings. We employ the simulator "Energy-plus" to estimate energy consumption annually and during critical months in summer and winter. To obtain the best orientation for maximum energy saving, different orientations are tested. It is found that an air-conditioned building that has a southern facade consumes less energy. However, a western facade causes higher annual energy consumption by 26% over the southern facade. In the case of a two-facade building, the lowest energy consumption is obtained between the northern and southern orientations in Cairo, Egypt.
Optimisation of building shape and orientation for better energy efficient architecture
Purpose – This paper aims to optimise building orientation in Tehran, as well as determining the impact of its shape, relative compactness (RC) and glazing percentage on its optimised orientation. Design/methodology/approach – A cubic module was used and a set of 8 of the same module with 16 different formations were analysed for their orientation (360°), the RC (four groups) and the amount of glazing percentage (25, 50 and 75 per cent). Findings – The results show that the optimised orientation of a building in Tehran strongly depends on its passive solar heat gain elements, their orientation and their position in building; furthermore, glazing percentage amount, amongst the studied factors, plays the most important role in determining a building’s orientation. Practical implications – The application of the findings of this study in Tehran city planning and also technical details of buildings will lead to a great energy saving in construction sector. Furthermore, the deployment of the proposed design guidelines in construction has explicitly been proven to save a prodigious amount of energy. Originality/value – The main research question is taken directly from authors’ initiative when working as university professor and research associate. The case study buildings, their morphological configurations and sustainable features have not been presented before in an academic journal. Keywords: Solar energy, Correlation analysis, Simulation, Optimisation, Regression, Orientation, Energy efficient architecture, Glazing percentage, Shape

Energy analysis was performed using Autodesk Insight360 in terms of kWh/m 2 /yr. Sixteen (16) story building, has been assessed at its proposed location, at 8° clockwise w.r.t true North. The study observed an annual consumption of 267 kWh/m 2 /yr which was further optimized by adopting different construction innovations. It has been highlighted that using virtual technology at the design stage of buildings can help to achieve an average annual energy saving of more than 50% thus supporting the goal for a sustainable future by accessing energy requirements at the early stage of design inception.
IRJET- Integrating BIM and Energy Performance for Sustainable Residential Buildings
IRJET, 2020
The Construction sector is the largest consumer of energy as buildings demand energy in their life cycle right from its construction to demolition. Therefore, it is important for the stakeholders to be concerned about the sustainability and energy performance of proposed building projects. Assessment of the energy associated with the production of construction materials, transportation and construction of buildings help in reducing the use of energy. BIM provides detailed digital representation of buildings that can be integrated with various energy modelling approaches to achieve a sustainable design and assessment of energy consumption. Analyzing the energy consumption of the building components at the conceptual and design stage is helpful in selection of the most suitable design alternative that will lead to an energy-efficient building. This paper focuses on the use of BIM sustainability design tools to achieve energy efficiency in residential buildings. Using Revit Architecture, energy demand will be estimated for a building. The effect of passive design techniques (planning and orientation, natural ventilation etc.) and material selection on building energy demand will be analyzed for the Warangal (Telangana State, India) region. The study will be helpful to make energy related decisions that have impact on the building energy consumption.

Building Information Modeling (BIM) is developing into a potent solution for the building and construction industry. The consistent development of BIM technology in the sphere of Architecture, Engineering, and Construction (AEC) industry has enhanced the effectiveness of construction and decision-making. However, aggrandized global warming and energy crisis has impacted building energy analysis. and is increasingly becoming an important factor to be considered in the AEC industry. As a result, amalgamating energy analysis in the planning and design phase of a structure has become a necessity. In the current construction industry estimating energy usage and reducing its footprint is off high priority. The construction industry is giving more prominence to sustainability alongside energy efficiency. This demand is compelling the designers, planners, and engineers to inspect the sustainable performance throughout the building's life cycle. The current study primarily focuses on energy consumption, space arrangement, and spatial geometry of a residential building. Most commonly residential structures in India are constructed considering Vastu Shastra. Vastu designs are intended to integrate architecture with nature and utilizing geometric patterns, symmetry, and directional alignments. In the current study, a residential brick masonry structure is considered for BIM analysis. Architectural model of the structure will be created using Revit software, later the orientation and spatial arrangement will be finalized based on Vastu principles. Furthermore, the structure will be investigated for the impact of building orientation and spatial arrangements on energy using Green Building Studio software. Based on the BIM analysis of the structure, energy consumption of subsequent building orientations will be understood. A well-orientated building having good spatial arrangement can save a considerable amount of energy throughout its life cycle and reduces the need for heating and lighting which will prove to diminish energy usage and improve the energy efficiency of the residential building.
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.

There is a great interest in building information modeling (BIM) and energy saving worldwide. In reality, however, insufficient studies have been conducted on the development of design methods to perform energy performance analysis. Thus, there is a problem that it is difficult to objectively obtain reliability in energy performance assessment of architectural designs such as scale and size of buildings. In addition, the energy performance analysis is considered as a different field from eco-friendly design methods, and there is another problem that low-carbon design methods more dependent on thermal insulation performance and heating ventilation and air-conditioning (HVAC) system than on original design methods are mainly developed. In order to solve this problem, this study aims to develop design methods capable of considering energy performance from the early design stage. Designers are required to intuitively understand the results through energy performance analysis using BIM t...
BIM-Based Optimum Design and Energy Performance Assessment of Residential Buildings
Iran Energy Association (IEA), 2020
Buildings are the largest energy consumer in the world, according to the United Nations Environment Program. Most of the energy will be used during the building life-cycle stage. Thus, achieving sustainable development at the national level requires minimizing the impact of buildings on the environment by reducing energy consumption. Using Building Information Modeling technology in energy performance assessment could be significantly reduced time and cost. This study aimed to optimize energy consumption in a residential building using BIM technology. The main focus of this study was to evaluate energy performance through the simultaneous evaluation of building components using BIM technology with a conceptual design approach, comparison, and reduction of energy consumption. To investigate different design ideas were created several conceptual masses in Autodesk Revit software with a top-down design approach. After reviewing the conceptual masses, the main building form was chosen for modeling. Then, building energy consumption was computed using related tools in this field, based on the type of materials, equipment, and project location. Finally, the most optimal mode was selected by examining different energy consumption forms. The results of parametric studies on alternative schemes of energy optimization showed that 58.46% of energy cost savings could be achieved compared to the initial model of the building on a 30-year time horizon.
