The presence of sunlight has an impact on the building in the form of heat radiation and natural lighting. Under certain circumstances, these two effects are contradictory. Buildings need natural lighting to reduce their reliance on artificial lighting, but adding this natural lighting also causes the building to become warmer, which will increase the energy required for air conditioning. One alternative solution to reduce the intensity of heat entering a building is the use of shading devices. The presence of sun shading is believed could be used to prevent heat radiation from entering the building, but the lighting intensity is not at its best. Educational buildings, particularly classrooms, are one type of building that utilizes natural lighting extensively. One of the educational buildings that has attempted to use shading devices. This research aims to determine the perfomance of natural lighting, especially uniformity in classsrooms that used shading devices. The research administers quantitative methods with Dialux Evo software simulation to determine the uniformity ratio of natural lighting in classrooms that use various forms of shading devices The research results reveal that the performance of classrooms with the four types of shading devices still does not meet standards. There is still a need for adjustments to the four types of shading devices so that their performance can meet standards.

Insufficient research has been conducted concerning this mosque-turned-building, particularly regarding how it may help the country accomplish its environmental commitments. The Istiqlal mosque received a green building assessment certificate (Excellence in Design for Greater Efficiency) from the International Finance Corporation in April 2022. This certificate should serve as a foundation for future research into the distinctive features of mosque building designs in Indonesia and their potential to contribute to accomplishing national environmental targets. Mosque buildings as an embodiment of the concept of Rahmatan Lil Alamin or mercy for all of nature should be in line with the concept of green buildings which strive to preserve nature. This research aims to determine the challenges of implementing the green building concept in mosque buildings with a case study of two mosques in the city of Bandung. To identify their traits, this study employed observational methods, case studies, and interviews with mosque managers. The Minister of Public Works Regulation Number 21 of 2021 about Green Building Performance Assessment will be employed to examine and assess the gathered data. The outcomes demonstrate that the low-performance value persists. Considerable work is required to achieve the desired results. In-depth talks with stakeholders are also required to map the distinctive qualities of mosque structures and identify methods in which they can support the realization of national environmental preservation objectives while also exemplifying the principles of Rahmatan lil Alamin.

A significant proportion of this energy consumption is for building operation including HVAC (Heating, Ventilating, Air-conditioning) to provide a healthy and comfortable indoor environment. Fossil fuels which generate the major proportion of energy are becoming increasingly scarce whereas energy generated from renewable sources is still not entirely popular, is still expensive and can only contribute a small amount of the total energy produced. The effort of many experts to create an energy-efficient mechanical or electrical system is commendable. However, the occupants can help to conserve energy by adopting energy-efficient behavior in their everyday life and accept a less comfortable but still acceptable indoor environment.

As urban architecture symbolizes and establishes the identity of a regime, authorities often use a top-down approach to implement urban architectural programs. As a result, the spaces constructed often display power and identity, but lack consideration of public use. Public spaces are often exclusionary for public use. They merely stand for the representation of the authority. Accordingly, many public spaces built by the government are abandoned soon after their launch. Big ceremonies and public space displays only last a few days before these spaces are then closed to the public or appropriated for different uses. Most top-down approaches focus on the physical development, overlooking the users’ inclusion in decision making. This research analyses the political representation of public space design in RPTRA Bahari located in the South Jakarta. It analyses the political reason behi...

In order to achieve an expected green building performance, Yeang (2005) suggest to optimize passive strategy before utilize the active strategy. Optimization of passive strategy will directly effect on the active strategy and also directly related to minimization of building's operational energy. In term of high-rise office building, practitioners faced with assumption that passive strategies are only suitable to be implemented on low-rise building. In some cases, there are several indications that practitioner tend to rely on active strategy and ignore passive strategy to optimize building's energy usage. This indication is reflected on building orientation preference of several high-rise building throughout Jakarta city, since they tend to direct the building to the street and ignore to consider the trajectory of the sun in avoiding direct sunlight radiation. From this stand point, we might assume that there could be different understanding between practice and theory or between architects as practitioners and academics as theorist related to the achievement of green performance of passive strategies on high-rise building. This paper tries to reveal the similarity and difference understanding of passive strategy's green performance between practice and theory in order to find direction of future passive strategy's implementation. The architects, as a representative of practitioners, and the academics, as the representative of the theorist, were asked using the same questionnaire to find out their understanding of passive strategy's green performance and the result will be analyzed to give direction for implementation of passive strategies in the future

The objective is to create buildings that consider the aspects of saving, maintaining and using resources efficiently throughout project life cycle. In the project life cycle, design has a significant role in achieving good performance of green building criteria. Any decision on the design phase that is listed in the design document (DED) will affect subsequent stages of the project life cycle, such as the construction phase as well as operation and maintenance. This paper proposes a review system of design documents in order to assess the sustainability performance of a building design based on criteria of green building. Review method is developed based on GBCI (Green Building Council of Indonesia) rating system and Jakarta Governor Rule regarding green building, since GBCI rating and the Governor Rule has been applied in assessing building based on the criteria for green buildings in Indonesia. The system developed will be tested in a case study which the results will be analyzed. Based on the analysis results, simulations on various alternative designs will be carried out in order to provide recommendations of the building performance improvement. The design review model is expected to be used in assessing the green performance of buildings design in Indonesia; thus, the buildings will have contribution positively to society and the environment.

First green rating tool was introduced by the Green Building Council of Indonesia (GBCI) in 2010 while the first government regulation on green building was introduced in 2012. Twenty years earlier, in 1990, UK have developed their green rating tool, BREEAM, that often be used as a reference for many council and nations in developing their green building criteria. Since Indonesia is very late in developing green criteria, Indonesia needs a shortcut in finding direction for the development. Lesson learned from developed country in implementing their green criteria could be used by Indonesia as a basis or reference in developing appropriate green building criteria. This paper presents a comparative study of green building criteria in developing countries, green building criteria in GBCI green-ship rating, and also green building criteria of Jakarta government regulation. The comparison is done by mapping any criteria listed in those documents. This study will also map the changes process of the criteria development in order to find the direction of the development of each criterion or each rating tools. In this study, the background or formulation contexts of each green criterion need to be carried out. Especially the environmental context is required to be analyzed in order to find the differences between green criteria. This study will focus on sustainability aspects so the comparative study can produce precise direction for the development of green building criteria with appropriate context towards Indonesia's sustainable Infrastructure development

Passive strategy refers to how the design of the building is able to interact with the external environment for the benefit of occupants and the environment. On the other hand, Active strategy use an effective and efficient electrical and mechanical equipment to meet the occupant's need and bring out a minimum damage to the surrounding environment. Passive strategy is not something new in architectural context; this strategy is a basic strategy that has been learned for years. However, the reality shows that the implementation of passive strategy is not simple, there are various reasons to consider since the project involved many factors and parties. The study began with interviews of project parties including architects and academics about understanding, role, contribution, willingness and constraints associated with the implementation of passive strategies in high-rise office buildings in Jakarta. The interview indicates that several factors considered by the architects during the design process in implementing passive strategy to the design product. These factors were then confirmed back to the architects using questionnaire to determine the weight of influence. Using the same questionnaire, architects and academics were asked regarding the green performance of passive strategies from their point of view. The green performance in this study represents concept of sustainability (environment, social and economy) and also concept of reciprocity (benefit and effort) of the passive strategies implementation. The results are then compared to obtain a clear direction for future implementation of passive design strategies. The findings are still preliminary since this is an on going research.

Passive strategy try to optimize and conserve the usage of potential energy around the building without converting it first to electrical energy. Otherwise, active strategy try to fulfill human requirement on comfortable environement using electrical-mechanical equipment. Which one plays the important role than another. Could each system stand alone without the support of another systems or should we combine those two strategy. The research will be conducted by comparing the advantage and the lack of each strategy. This research will help us to understand the role of passive and active system. This research will also give benefit to the development of green building because optimizing and conserving energy is one of the green building concept Keyword : green building, passive system, active system.

Building as built environment with a particular physical form at a particular location is affected by climate. If the building design process ignores the climate considerations, the influence of climate can lead to interference human activities. Bioclimatic design is a concept of sustainable approach that consider of climate and human relations in reviewing the feasibility of a design. At this time, a growing number of designers, especially young architects that interested in using bioclimatic concept as sustainable approach in their design process. However, the application of this concept in the design process has not shown significant results in building operation. This paper elaborates the bioclimatic concept, in order to obtain a good understanding of bioclimatic design that can be used as a reference, especially for novice designers, in the application of sustainability concepts in the design of multi-story buildings in the tropical area. This paper also suggests a design method that utilizes a sustainable approach which is expected to help novice designers in applying the bioclimatic design concept.
