The issue of climate change has not received enough attention from the stakeholders. Even though, if not handled seriously. Climate change can have an impact on the economy of a region.
The Asian Development Bank noted, climate change could cause losses of up to 13% of Indonesia’s Gross Domestic Product at 2,100.
The ADB projection is certainly not excessive, according to General Chairman of the Indonesian Real Estate (REI) Soelaeman Soemawinata, global warming due to climate change impacts on the high energy consumption for air conditioning.
“We have felt the effects of these days in the form of rising temperatures, pollution and garbage, unpredictable and unpredictable weather, floods, droughts, chaotic planting seasons, crop failures, and the more difficult it is to get clean water,”
According to him, the problem can actually be overcome, one of which is the development approach commonly known as green building.
“That is the concept of building design that seeks to reduce energy and water consumption,” he said.
The concept is to provide infrastructure that supports green lifestyles such as the high access of pedestrians and cyclists as well as the means of water absorption and clean and dirty water management systems.
Landscape architect and green property observer Nirwono Joga revealed, to build smart green properties it is necessary to build interconnected strategic areas, support each other, in building local food security, overcoming floods and breaking down traffic congestion, providing cheap and livable housing, and opening fields work and equal distribution of people’s welfare.
There are 8 + 2 attributes that can be developed to achieve this goal.
First, developers apply environmentally sound planning and design. Developers are encouraged to consistently develop residential areas based on Spatial and Regional Plans (RTRW), Detailed Spatial Planning and Zoning Regulations (RDTR-PZ), and Building and Environmental Management Plans (RTBL).
Second, the developer is committed to providing RTH 30% of the total city / region, with 20% Public RTH and 10% Private RTH. Large parks and trees everywhere. Parks and green lines form a green infrastructure network.
Third, residents are accustomed to walking or cycling to nearby destinations, and are connected to public transport networks to get out of the area.
Fourth, residents reduce and choose and sort waste since at home. Waste is processed under the 3R + principle (reduce, reuse, recycle, repair, etc.).
Fifth, the area is designed to be responsive to the phenomenon of global warming by anticipating, adapting and mitigating climate change.
Sixth, buildings and housing use green building requirements. Save wise land, water saving installation, nothing is wasted. Save electricity and meet needs, air circulation in the house is fresh, flowing smoothly, and lighting is adequate.
Seventh, build the independence of renewable energy by utilizing local potential in the form of micro hydro, biogas, solar, or wind power.
Eighth, residents build a voluntary spirit, mutual cooperation, care for the environment, social culture, and care about the development of the city.
Ninth, fostering an economy that is more environmentally friendly and increases local sustainable income.
Tenth, supported by environmentally friendly developers, regional regulations and a proliferating budgeting system, and gave an example to the community in applying the principle of intelligent green living. Participatory, transparent, accountable, synergistic and sustainable.
These attributes were introduced through the Green Property Awards (GPA) held by HousingEstate since 2009. This method is expected to encourage developers to develop sustainable properties, while providing guidance to consumers in choosing such properties.
“In principle, project appraisal is still based on eight criteria which are considered to have the most influence on the sustainability of a city,” said Joga.
Unfortunately, the application of green areas is still very minimal in Indonesia, especially in Jakarta.
“It must be admitted that there are still very few cities and property projects that are able to meet these criteria, even even city-scale projects,” said Joga.
In the eyes of most developers, the application of the green concept is still considered a burden because it will increase development costs. As for most consumers, eco-friendly property is still considered an issue over the sky that has nothing to do with their daily lives.
“On the other hand the government also does not provide incentives for developer companies to implement the concept of sustainable property or city development seriously and consistently, even though Law No. 1/2011 concerning Housing and Settlement Areas has mandated it,” he said.
