Development of the Life Cycle Analysis (LCA) Method in calculating Embodied Energy Materials on Residential Buildings

One of the benefits of BIM towards a sustainable design is it can make a design system that will calculate the building energy in aim to give alternatives on energy-efficient design. BIM can be utilized to integrate the calculation of Embodied Energy (EE) Building Materials with the Life Cycle Analysis (LCA) method. EE calculation could be easier for architects; hence, the architects can understand the impact of carbon emissions caused by construction activities during the design process. This paper aims to provide an overview of the use of BIM in calculating the EE value of the designed building material on the apartment project. Since the development and construction of flats and apartments, especially in Indonesia, are growing fast, this will give highly environmental impact if it is not properly controlled. The results showed that the BIM implementation in calculating the EE value could be done. Collaboration with other platforms can also be done to make the final calculation, and it will be displayed in attractive data visualizations. The percentage comparison of the embodied energy value in all of the building component materials can also be seen in the results of the analysis. In this case, the highest embodied energy percentage is the structural component, which is 53.16%. It is hoped that the development of this calculation method will contribute to the development of LCA so that EE can be easy to be calculated and have a good impact on the construction industry in the future, especially in Indonesia.

Development measures for slums of Dhaka city : Case study area Korail slum

Dhaka, the capital city of Bangladesh is extremely populated, unhygienic and environmentally degraded city. The growing number of population and environmental degradation are due to natural disaster and economic depression. As a result, the rate of urban poor is and producing huge pressure on urban lands, housing and infrastructure. Due to limited resources these poor people encroached open spaces, wetlands, vacant plots or even footpath for shelter. They don’t have any access to proper job market, healthcare facilities, education and sanitation either. These constraints are mostly resulted from the failures of the government in initiation proper policies and measures. Past policies of slum clearance, modernist apartment projects, housing provision, self-help, sites and services, and in-situ upgrading have not been effective at solving the crisis. This is now prime time to established planning and environmental management policy and sustainable development of the city area. Urban land management, rehabilitation and socio-economic development of the slum dwellers are also very important issues. The key focus of this paper is to find out sustainable development process for urban slum dwellers and build sustainable living place for them which are free from eviction, criminals, rent seekers and other miscreants.

Notary Responsibility to Make Apartment Agreement According to Indonesian Legal System

In making the deed of the Sale and Purchase Agreement, before the notary must ensure in advance about the requirements ordered by the Act as in Article 43 of the Flats Law, because a Notary in carrying out his authority as a general official is a perfect evidence maker of course must be responsible for the deed he made. The problem here is how to measure against 20% (twenty percent) of the construction, because considering the absence of provisions of construction 20% (twenty percent) are in the apartment or other regulatory provisions. This will certainly make it difficult for the notary to make a binding agreement on the sale and purchase of flats. In making the deed especially on the Binding Agreement for Sale and Purchase Agreement this Flats will be the responsibility of the Notary as the official maker of authentic deeds to pay attention to the provisions of the conditions ordered by the apartment project, so that the deed is made by the notary will not be found later. Based on the description above, the enactment of the apartment law will have an impact on the Notary as a general official who has the authority to make authentic deeds, and here the author wants to see the role of the notary in making a Flat Sale Purchase Agreement, in accordance with Article 43 of the House Law Arrange.

The residential buildings of the 1960s architectural renovation

This article examines the relevance of architectural renovation, in particular the renovation of the industrial house-building first generation old residential buildings. The typical apartment projects with economical apartments developed in 1957-58 were very timely in solving the social problem of settlement, and were designed in two categories - the long and short lifetime. Existing physical deterioration makes it possible to consider their renovation question, since such a type of dwelling is in demand as affordable and cheap housing. This article deals with the features of planning decisions of the 1960s housing stock, emphasizing the elements that do not meet modern functional requirements. A program for renovation of residential buildings of the 60s is proposed. It allows to approach the modern standards of housing. Attention is paid to the algorithms of the apartment redevelopment: with the preservation of the number of apartments on the floor, or with the apartments consolidation. Possible constructive variants of superstructures from the mansards to several floors are considered. The renovation program was experimentally tested on the example of the Rostov-on-Don city, as a part of an academic design. Residential buildings of the 60s were chosen as objects. They are located in the urban areas that have lost their compositional structure due to new construction in order to simulate various options for superstructures.

Government-backed ‘laundering of the grey’ in upgrading urban village properties: Ningmeng Apartment Project in Shuiwei Village, Shenzhen, China

Urban informality and informal settlements, as research concepts rooted in the global south, have the potential to reveal the relationship between property improvement, tenure security, uneven distribution of resources and asymmetric power relations embedded in urban studies. Investigations of urban villages in China are also inspired by these ideas. The present study of the Ningmeng Apartment project in Shuiwei Village, Shenzhen, China, aims to contribute to these exciting research fields by (1) offering a new governmental mechanism – government-backed informal formalizing of informality – that can strengthen perceived tenure security; (2) investigating a new approach to regenerating problematic urban villages; and (3) revealing a new social-psychological effect underlying the operation of urban informality: perceived formal informality. These three dimensions can be interpreted as government-backed methods of laundering the grey, ways in which state actors use informal operations to strengthen the perceived tenure security and upgrade the spatial quality of informal properties to achieve governmental goals. Based on these three academic contributions, interactions between rule-breaking innovations and a pre-innovation environment emerge from the examination of the Ningmeng project. Such interactions may reflect the experience of China during its post-1978 reform and may inspire new policy practices in other developing countries.

A Big Data and FMEA-based construction quality risk evaluation model considering project schedule for Shanghai apartment projects

PurposeThe purpose of this paper is to mine information on the construction process of previous projects to develop a construction plan that meets both quality requirements and schedule constraints.Design/methodology/approachThis paper uses a failure mode and effect analysis to evaluate the construction quality of 311 apartments in Shanghai. The authors also evaluate construction-scheduling control using the earned value management technique and implement an artificial neural network to correlate the results. The authors then develop a quality risk and schedule correlation model based on Big Data. The model can predict the relationship between the planned schedule and the project quality risk using multiple variables such as the number of layers, the schedule performance index and budget costs.FindingsThe methodology offers an innovative approach for assessment on the relationship between quality risk and project schedule. The authors have also built a multiple regression analysis model for comparative purposes with the model. The results show that the proposed model can better describe the relationship. The model can provide a quantitative quality risk value that changes with the planned schedule, as well as help project managers to understand the relationship between quality risk and project scheduling more accurately.Research limitations/implicationsThe research approach only focuses on quality risk under the impact of scheduling. Future efforts might focus on developing a model that connects failure models with project schedules and costs in order to improve the effort of quality management.Practical implicationsThe model based on Big Data in this paper is developed using real projects and reflects the relationship between project quality risk and scheduling in real environments. The created application provides support for project managers to develop and adjust quality plans and schedules, thereby reducing deviations in quality and scheduling objectives.Originality/valueThe authors make full use of historical project data from the perspective of both quality and schedule management, and provide a novel method to intelligently and objectively analyze the relationship between quality risk and scheduling.

Effectiveness and efficiency of kitchen space reviewed from the kitchen triangle concept in small flats case study ‘Rusunawa’ Manis Jaya, Tangerang city, Banten

The increase in population led to the narrowness of the land mainly for housing and settlement needs. Therefore the presence of housing and settlements vertically is one of the alternative solutions in solving this problem, one of which is the apartment project targeting low income citizen (MBR). But in fact in most cases in big cities, precisely due to the narrow residential area, many cause new problems such as narrow space and also the function of space so that space becomes ineffective and inefficient. This research was conducted with the aim to examine the effectiveness and efficiency of kitchen space as one of the space facilities that support family needs in food in simple flat unit with a case study of Rusunawa Manis Jaya, Tangerang City. The method used in this research is comparing the condition of existing kitchen space in flat units in Rusunawa Manis Jaya with the parameters about the effectiveness and efficiency of the kitchen space by using the kitchen triangle concept issued by the National Kitchen and Bath Association with the aim of producing a recommendation that can be used by managers, designers and users in designing the kitchen to support users in terms of effectiveness and efficiency of kitchen activities in the kitchen itself. From the results of the research on the effectiveness and efficiency of the kitchen space based on the kitchen triangle concept, it can be concluded that the kitchen space in the Rusunawa Manis Jaya unit has met the standard from the space requirements, but has not fully met all these parameters issued by National Kitchen and Bath Association so that the effectiveness and efficiency of the kitchen space in the flat unit in Rusunawa Manis Jaya is still not compatible with the parameters.
