most of the world’s poorest nations will be hit first (and likely,
hardest) by climate change

COP21: Paris Agreements
 UNFCCC: United Nations Framework Conventions on Climate Change in
Paris in December 2015
 To control the global temperatures to not exceed 2 degree Celcius
from the Pre-industrial era.
 195 Nations agree to reduce green house gas emission and submit plan
and report in the year 2020
 Green Climate Fund (GCF) of 100 Billions USD to support developing
countries to apply green technologies.
18

Paris Agreements & Thailand
 Thailand committed to reduce greenhouse gas emission by 20-25% by
2030.
 Thailand’s plan to reduce emission. By 2036;
 Power Development Plan: Generate alternative energy by 20%.
 Reduce the Energy Intensity by 30% from the base year of 2010.
 30% of energy consumption must be from renewable sources.
 Climate Change Master Plan
19

 Among the world’s largest economy, THAILAND is ranked the last for
building energy efficiency (ACEEE report 2016).

Urban Heat Island:
Not enough green area
Not enough water retention
Too many concrete pavement
Too many cars
Too many air-conditioners

BANGKOK TEMPERATURES (Year 1840 & Year 2000)

Singapore has 66 m2 of green area per capita.
Bangkok has only 3 m2.
AMONG THE LEAST IN ASIA
W.H.O. recommends10 m2 for healthy city environment.
(source: The Economist Intelligence Unit)

BANGKOK NEW CITY PLANNING CODE
 Bangkok immediately needs a lot more of green area
 New city planning code: 50% of open space must be
green !!!
 Development density incentive (5-20% more buildable
area) for green buildings.

New City Planning Code: BONUS
1. Affordable housing
2. Urban public space
3. Mass transit Park & Ride
4. Stormwater runoff
5. Green building

F.A.R. Bonus & Green Building
 Would green building certificate increase the rent ?
 If so, how much? 5%, 10%, 15%, 20% ?
 If so, does different certification levels matter ?
 If so, does it mean tenants get benefit from it ? What benefit?
 In exchange with higher rental rates, do tenants enjoy money
saving? energy saving? low-carbon? good image?
 BUT…once developers get F.A.R. Bonus ? Should the sale
prices be lower?
