APEC Low Carbon Model Town Project Phase1 Tianjin Yujiapu Feasibility Study
Outline of Yujiapu financial district- The financial district occupies approximately 4km2 with a total construction area of
9,500,000m2 *4
- Total planned daytime population is 500,000 and nighttime population is 50,000.- Construction is ongoing in some part of precedent development area.- Most of architectural planes within this district are selected by international competition.
3. Outline of Yujiapu Financial district
Location Tianjin Yujiapu financial district in Binhai new area

APEC Low Carbon Model Town Project Phase1 Tianjin Yujiapu Feasibility Study
Prepare a Low-Carbon Strategy for Yujiapu CBD based on “LCMT Concept”
Framework of LCMT FS in Yujiapu
(0) Investigate the detailed information about Yujiapu necessary for FS
4. Construction of the LCMT concept
(1) Develop a comprehensive concept for low carbon town development
(2) Define the CO2 reduction targets and other concerning indexesfor evaluating the progress of low carbon
(3) Prepare the categories to make low carbon challenge in urban development
(4) Select and develop CO2 reduction measures in each planning category
4
Analyze CO2 reductions and cost increase of measures in each category

[ Aiming at real reduction of approximately 50% ]In 2020 (mid-term) real reduction of approximately 30% (which is over 50% CO2/GDP)
In 2030 (long-term) real reduction of approximately 50%

In this CO2 target study, the GDP growth by 2020 is set as 5% that is around ½ of the actual growth with consideration of uncertainty of prediction.3) Mitigation effects by area energy, renewal energy and untapped energy have been counted into the result of CO2 reduction in Buildings
