2 Why isn t everyone building green buildings? 1. Absence of market demand for efficient Buildings 2. Building regulations are not set up yet 3. The voluntary standards is not widely adopted by the mass market 4. Lack of technical capacity 5. Ineffective financing and incentives

3 How can these hurdles be removed? 1. Absence of market demand for efficient Buildings 2. Building regulations are not set up yet 3. The voluntary standards is not widely adopted by the mass market 4. Lack of technical capacity 5. Ineffective financing and incentives Increase market awareness by standardization, develop and demonstrate business case for green buildings Help governments develop and enforce green building codes Increase voluntary standard adoptiondevelop and launch simple, low cost rating Increase capacity of government & professionals- thru training, tools & guides Facilitate financing of green buildings- thru direct investments and developing green loans with local banks

4 Indonesian Target Reducing CO 2 emission : 26% on 2020 Jakarta Target Reducing CO 2 emission : 30% on 2030 Green Building Green Transportation Green Waste Green Park ETC.

5 Peraturan Gubernur DKI Jakarta no. 38/2012 tentang Bangunan Gedung Hijau Jakarta Green Building Code

6 Green Building Code Development Approach Building Stock Analysis Based on market survey & stakeholder discussions Virtual Model for multiple building types Sensitivity Analysis To quantify potential savings and cost paybacks Implementation List Based on agreed criteria and stakeholder discussions

7 Building Sector New buildings Older Buildings typically waste less resources. Rapid construction growth in region. Mandatory and Voluntary standards Development Approach Selected and Targeted Resource Type Energy Water Materials (listed according to typical priority) Alignment with national priorities Building Type Apartments Hotels Offices Retail Hospitals Building types with high volume and/or high savings potential.

8 Scope and Impact of Jakarta Green Building Code 17-36% energy and water savings expected for various building types Vs baseline

9 Expected Energy Use Intensity for Typical Building (kwh/m2) Expected Savings Due to GB Code % % 34% 35.0% % 31% 30.0% % 17% 25.0% 20.0% 15.0% Base Code Saving % % 0 Office Hotel Hospital Retail School Apartment 0.0%
