Study Case

One of the school's successes in reaching the title Adiwiyata is habitual school community in everyday life. These habits reflect whether they are environmentally friendly patterned or not. Adiwiyata is a program that forms the entire school community to characters that care for the environment. Creating a school that is clean, healthy, beautiful and ethics and aesthetics. With the knowledge and habits of students' awareness and eco-friendly lifestyle, it is the foundation for SMA Negeri 8 Kota Serang to be earned Adiwiyata. This study raised the issue of whether the program launched by the school for a degree Adiwiyata can increase knowledge and change the habits of students in energy efficiency. This research method using qualitative description, in which respondents were given questionnaires, interviews, and observations. However, the role that the school community is very important in realizing the success of the school to achieve Adiwiyata title. Thus the required environmental education activities that can form the students become the generation that can contribute to being part minded citizens who are environmentally.

This research responded to environmental issues that arise related to green design as the responsibility of architectural actors. A building is now required to have environmentally friendly values, one of that can be reflected in the energy efficiency of the building. Kudu Flats is one of the towers in the city of Semarang which had several blocks with different orientations. Related to these environmental issues, this study aimed to determine the level of energy efficiency in the Kudu flats with consideration of building orientation, openings and shading devices using quantitative methods based on edge design. This study revealed that flats blocks that have smaller openings in the east-west direction are more energy efficient and rotating the building orientation 15 ° from the wind direction will make the building more energy efficient.

Technological Developments

<p><em>Along with technological developments and population growth, the need for air conditioner (AC) is increasing, both those used in industry, offices, buildings, housing, vehicles, and others. In the use of AC, refrigerant is needed. Based on the Montreal agreement, it was agreed to replace refrigerants that are more environmentally friendly. The refrigerant used today is refrigerant with CFC and HCFC compounds. The use of those refrigerants result in ODP and GWP. This study aims to determine the energy efficiency of three refrigerants: R12, R134a, and MC134, by comparing the COP value of a refrigeration laboratory unit machine. Based on the test results, COP of MC134 refrigerant has the highest value compared to R12 and R134a refrigerants. Therefore, it can be concluded that MC134, a hydrocarbon refrigerant, could be considered as a substitute for R12 and R134 refrigerants, eventhough  flammability of the  hydrocarbons at certain temperatures should be considered also.</em><em></em></p>

The Future

Abstract This research presents the results of investigation and analysis of the environmentally friendly refrigerant for R22 replacement. All refrigerant properties in this research were based on results from the REFPROP and CYCLE_D-HX software of NIST under CAN/ANSI/AHRI540. The results of this work show that HCs R170, R290, R600, R600a, R601, R601a, R1150 and R1270 can be mixed in HFCs R417A, R417B, R422A, R422B, R422C, R422D, R424A, R437A, R438A and R453A and able to be further developed in the future. All refrigerants are non-flammable refrigerants, non-toxic and zero ODP. The R453A mixed with HCs R600 (0.6%) and R601a (0.6%) and is COPc refrigerant close to that of R22 refrigerant. In conclusion, it can be used as an environmentally friendly and energy efficiency replacement for R22. All refrigerants are also refrigerants that are matched with the 4th generation refrigerants with the use of natural refrigerants.
