Conservation of Building Veil Energy in Government Offices in Medan: Case Study of the Medan High Court

Energy Efficiency in Government Offices: A Growing Concern

Energy savings in government offices, especially through the air conditioning system, have become one of the important programs of the Ministry of Energy and Mineral Resources. Buildings, especially in urban areas such as Medan City, face big challenges in managing cooling burdens. This load consists of internal loads, namely heat derived from daily activities, such as lights, residents, and electronic equipment, as well as external loads caused by solar heat entering through the building sheath. This process occurs through three mechanisms: convection, conduction, and radiation.

The Importance of Building Sheath Design Criteria

To increase energy efficiency, the Indonesian National Standard (SNI) 03-6389-2011 establishes building sheath design criteria using OTTV (Overall Thermal Transfer Value). This value is limited to a maximum of 35 watts/m². In this study, the quantification method was used to evaluate the value of OTTV in the Medan High Court Office building. The results show that the current OTTV value does not meet the specified criteria.

Analysis and Solution

Knowing that the Medan High Court OTTV is not in accordance with the standards, energy conservation steps need to be taken to reduce the value. One of the solutions made is the modification of the window ratio to the wall (window to wall ratio/wwr). By reducing the number of windows or replacing windows with a more efficient design, the heat that enters the room can be minimized.

The Role of Window Design in Energy Conservation

The selection of the color of the building's outer paint can also play an important role in energy conservation. Paint with bright colors can reflect more solar radiation than dark colors, thus helping to reduce the burden of cooling in the building. This is because bright colors have a higher albedo value, which means they can reflect more sunlight and reduce the amount of heat that enters the building.

The Benefits of Double Glass in Energy Conservation

Modification of the use of dual glass is another effective solution. Double glass not only provides better insulation, but also reduces heat transmission into the building. Thus, the use of double glass can significantly reduce OTTV values and increase the comfort of residents. Double glass works by creating a gap between two panes of glass, which reduces the amount of heat that can enter the building. This can lead to significant energy savings and a more comfortable indoor environment.

Conclusion

Through these efforts, it is expected that the Medan High Court Office can meet the criteria stipulated in SNI 03-6389-2011. Energy conservation not only reduces electricity consumption, but also contributes to reducing carbon emissions and environmental preservation. The implementation of these steps is expected to be an example for other government offices in maintaining energy efficiency amid the rapid development of urbanization.

The Future of Energy Efficiency in Government Offices

As the world continues to urbanize, the demand for energy-efficient buildings will only continue to grow. The Medan High Court Office case study provides a valuable example of how energy conservation can be achieved through simple modifications to building design. By reducing the OTTV value, the building can reduce its energy consumption and contribute to a more sustainable future. This is a crucial step towards reducing carbon emissions and mitigating the impacts of climate change.

Recommendations for Future Research

Future research should focus on the implementation of energy-efficient building design in other government offices. This can include the use of advanced materials and technologies, such as solar panels and green roofs. Additionally, research should be conducted on the economic benefits of energy-efficient buildings, including reduced energy consumption and increased property values.

Conclusion

In conclusion, the conservation of building veil energy in government offices in Medan is a crucial step towards reducing energy consumption and contributing to a more sustainable future. The Medan High Court Office case study provides a valuable example of how energy conservation can be achieved through simple modifications to building design. By reducing the OTTV value, the building can reduce its energy consumption and contribute to a more sustainable future.
