In the scope of Southeast Asian countries, Singapore has since 2005 been at the forefront as a successful country with its green building certification system BCA Green Mark. Since 2008 the Green Mark certification system also applies to new buildings and existing buildings with an area of ??more than 2000 m2. Currently BCA Green Mark has already certified over 1500 buildings.
Malaysia's neighboring country also with the GBI (Green Building Index) certification system created in 2009, has certified more than 100 green buildings. Green building certification in Indonesia is conducted by non-profit GBCIndonesia. From the establishment of the certification system for new buildings in 2010 until 2014 only 10 certified buildings, 5 new buildings, 4 existing buildings and one interior space.
Is it a green building? Already many posts in Kompasiana showing good writings that HL and not HL about green buildings, including:

Is it free of green building certification or check implementation / energy proof for buildings in Indonesia? Why is the awareness of green building construction in Indonesia not having a big impact on building practice? This article is continued from my writing yesterday, all complement the answers of comments from Mbak Herti Utami.
Electricity and Green Building
Electricity savings, just one of the green building targets. However, given the fact that the condition of Indonesia's existing electricity, I assess the building certification or check / building energy evidence in Indonesia should be important and precarious nature. But in practice, alon-alon, sometimes expired national standards color the practice of energy saving in us.
Dreams have a road map and the German energy efficiency, conservation and conservation practices are likely to continue for a long time. The concept of cradle to cradle, the rapid actualization of energy engineering standards in Germany is too difficult to be followed by Indonesia, which has just installed electricity capacity by the end of 2014 by 40 GW, while Germany has reached 189 GW. However, I am very proud, Indonesia in the past 3 years managed to increase the installed electricity capacity of almost 10 GW. News from here even end of 2014 installed electricity capacity in Indonesia 53 GW.

In the concept of green building, the quality of the building is very determine the consumption of electricity, especially cooled buildings or berac, because the consumption of air conditioning dominate the existing electricity consumption. The quality of this building is greatly affected by the building quilts and the quality of the window glass. The better the quality of building blankets and window glass then the smaller the heat leak. If in Germany the heat is cultivated not out building then in Indonesia or other tropical countries, heat cultivated not enter the building so that room temperature can be maintained remain comfortable.Building Quality Improvement for Electricity Savings Building berAC free in Indonesia ??
Not a few I believe that think it is useless to improve the quality of buildings to save electricity, especially electricity for air conditioning, because it does not have much effect on national electricity consumption. Is it true ??
Let's study the above PLN data and its links.
From PLN data of 2014 electrical energy sold is 198.6 TWh, 42.3% sold to household sector means 84 TWh. The household sector in Java consumes 64% of the total consumption of the Household sector is 54 TWh. The highest consumers are West Java & Banten (17.4 TWh) and Jakarta Raya & Tangerang (14.3 TWh).
Who entered the household sector was the S-1 goal. R-1. R-2 and R-3, where 84 TWh consists of S-1 of approximately 4 GWh, R-1 is approximately 75 TWh and the remaining R-2 and R-3 is 8.7 TWh.
If I calculate only 10% of R-1 customers have AC then the total electrical energy of customers berac (0.1×75 TWh + 8.7 TWh) = 16.2 TWh. If the electricity consumption for the air conditioning in my experience is 50% of total electricity consumption then the electricity for air conditioner alone in this household sector total amounts to 8.1 TWh !!!
Imagine if the quality of the building repaired and can save electricity for air conditioning to 5% only then the national savings can be up to 0.4 TWh especially if up to 25% means 2 TWh. Please add up to 0.4 TWh or 2 TWh it equals the self-generated electricity produced in any province.
Though it's new electricity savings in the building of the household sector, there are still commercial buildings and industries you know.
Namuuuunnnnnn, although this is interesting from the electricity savings but in practice, the investment to make this energy-efficient building is not small and our electricity tariffs are still subsidized because of that awareness of green building does not penetrate the market and not as a result in Singapore or Malaysia.
Government subsidy in 2014 alone from PLN link above is 99 Trillion Rupiah. So no wonder is why energy-saving buildings or green buildings are not booming like in Singapore, Malaysia let alone like in Germany when precarious and important. (ACJP)
