According to Indonesia's National Guidelines on Green Buildings (Kemen PUPR No,21,2021) called Penilaian Kinerja Bangunan Gedung Hijau (BGH), green buildings are mandatory for new and existing buildings. As environmental concerns grow, the Government uses these ratings to control energy consumption. A government initiative aims to increase demand for environmentally friendly buildings. This paper evaluates BGH's green building rating system for project certification in two Indonesian cities, Jakarta and Padang Paser Utara. Jakarta is the capital of Indonesia, the largest and one of the most populous urban city in Indonesia. Moreover, the new Indonesia capital city, Nusantara, will be built in Penajam Paser Utara, East Kalimantan. Using the results of this research, recommendations and suggestions can be given related to the design of green buildings both in Jakarta and Penajam Paser Utara. Evaluations will be conducted on simple residential buildings. The results of these studies indicate that designers and architects may have difficulty incorporating this rating systems into their designs. An evaluation of BGH ratings and sustainability analysis can be performed with building information modeling and a conceptual framework is presented toward the end of this paper. A rating system's success depends heavily on discussion among all stakeholders, including architects, engineers, environmentalists, governments, and communities. Indonesian experts in the building sector should take part in and contribute to this project. [ABSTRACT FROM AUTHOR]

This paper describes the development of a blended-based sustainable training model. The blended learning model is used to overcome participants' limited time constraints in ongoing training to increase the competency of tourism village community empowerment facilitators. The research method used is development research. The research subjects were community empowerment facilitators in tourist villages, DKI Jakarta, and West Java. The data collection techniques used were observation, interviews, and literature review. Data analysis in this research was carried out using qualitative descriptions. The study results show that conceptually implementing a blended learning-based continuous training model increases facilitators' competence in empowering the Tourism Village community through the stages of input, process, and output analysis. In the input component, the training manager maps the competency of the facilitator's objective conditions; the training process component uses an andragogy approach where participants have self-concept practical experience and can overcome the problems they face; and the output component produces tourism village facilitators who master three competency elements, namely basic, core and special.

There are three important elements that need to be harmonized so that the Sustainable Development Goals (SDG's) can be achieved, namely economic growth (economic growth), social inclusion (social inclusion), and environmental protection (environmental protection). The Environmental Performance Index (EPI) 2020 places 180 countries on environmental health and ecosystem vitality, Indonesia ranked 116th. The indicators provide environmental policy targets, environmental performance and provide practical guidance for countries aspiring to move towards the sustainable future. Environmentally sound development is also supported by the government at the policy level in the form of Regulation of the Minister of Public Works and Public Housing of the Republic of Indonesia Number 21 of 2021 concerning the Assessment of Green Buildings. Through this regulation, the government wants to encourage the realization of the implementation of sustainable buildings that are characterized by efficient use of resources and their contribution to reducing greenhouse gas emissions (GHG emissions). The target is to reduce GHG emissions based on DKI Jakarta Governor Regulation No. 131 of 2012, namely from non-provincial buildings of 1.5 million tons of CO2 emissions in 2020 and 5.5 million tons of CO2 emissions in 2030. While the target of the provincial government building itself in 2020 is 49.4 thousand tons of CO2 emissions and in 2030 of 129.5 thousand tons of CO2 emissions. This paper is intended to evaluate the application of Green Retrofitting in Existing Office High-rise Buildings, and proposed alternative ways in order to improve efficiency and effectiveness of Green Retrofit in Existing Office High-rise Buildings development and financing.

To get the OTTV value, you must first calculate the solar radiation value. Solar radiation occurs as a result of the sun's heat being exposed to the surface of the building and then goes inside so that the air temperature inside the building gets hotter. The solar factor is one of the elements of solar radiation which is important in determining the overall thermal transfer value for each outer area of a building. The availability of solar factor data in one place is very important to use for building design purposes. Calculating the solar factor is very difficult, moreover, SNI only contains data for the city of Jakarta. There are several ways to calculate the solar factor, with available SNI tables or by laboratory experiments or direct measurements of sunlight. So to make it easier for the designer, we propose to use the rule of thumb formula. The method used is based on local solar factor data, then a radian angle is made from 0 ° -360 °, which results in an ellipse shape in an equation. This paper concludes that the Rule of thumb formula is very helpful for architects in calculating the SF value and can also complete the table in SNI: 2011, which only contains the SF value for the city of Jakarta, meaning that it only applies in Jakarta, so similar research is needed to get the SF value for other cities in Indonesia.
