1 Energy Efficiency in Buildings: Policy and Programs in Tokyo Yuko Nishida Tokyo Metropolitan Government-Environment

2 Agenda 1. Background information & Tokyo s policy 2. Major Programs for Existing Buildings 3. Major Programs for New Buildings 4. Some Results

3 1. Background Information & Tokyo's Policy

4 Energy Consumption in Tokyo by sector Industrial Transportation 10% 24% 36% Commercial Residential 31% Emission from the Buildings Sector

5 Tokyo s Building Stock New Buildings (5 years or younger) 6% Existing buildings (2011) 94%

6 Tokyo Climate Strategy TARGET 25% Reduction in GHG Emissions 20% Reduction in Energy Consumption By 2020 from the 2000 level

7 Framework of Tokyo Program Larger New buildings Existing buildings Building Size District Plan for Energy Efficiency Developments w. incentive bonus Green Building Program Cap & Trade Program CO 2 Emission Reporting Program Smaller Planning/Operation Stage Planning Design Construction Operation Tuning Retrofit

8 Tokyo's PolicyinBEEin 1. Approach to Both New & Existing Buildings 2. Ratings & Disclosure 3. Utilize Existing (Naitonal) Programs and Standards and Require Higher Performance 4. Incentivize Further Improvements

9 Policy Development in Tokyo Plans The 10-yr plan Setting the target TMG environmental master plan Setting sect oral targets & programs Programs Climate Change Strategy Basic policy for the10yr project Carbon Minus 10yr project Action plan CO 2 Emission Reporting program 2002 Start 2005 Revise Introduce Disclosure system Reporting Program for SMEs Tokyo Cap& Trade Enact Start Green Building Program 2002 Start 2005 Revise 2008 Revise Green Labeling Program for Condominiums District Plan for Energy Efficiency

10 2. Major Programs for Existing Buildings Tokyo Cap & Trade Carbon Reduction Reporting for SMEs

11 Tokyo Cap-and-Trade Coverage and Scope Coverage Covers 1,400 facilities with energy consumption over 1500kl crude oil eq. Mainly buildings in the commercial sector Covers 20% of Tokyo's total CO2 emissions 40% of commercial and industry sector emissions Compliance Period in two five-year compliance periods ( , )

12 Tokyo Cap-and-Trade Coverage and Scope Total CO2 Emissions: 59 million tonnes (FY2010) Emissions Number of Facilities Transportation 21% Households 30% Commercial & Industrial 47% i 40% Large CO 2 emitting facilities Small & medium 60% CO 2 emitting facilities 1,400 facilities =0.2% More than 700,000 facilities =99.8%

13 Tokyo Cap-and-Trade Cap & Allowances Cap 6% reductions for the 1st phase, 15% for the 2nd phase (two 5yr periods ) Compliance Obligation Covered facilities are required 6 or 8% reductions over a 5 year period from their own base year emissions All All ti Allowance Allocation Grand-fathering, for free

14 Tokyo Cap-and-Trade Cap setting Base-year emissions 1 st period 2 nd period ( ) ( ) 6% reduction 5yr average 15% reduction 5yr average

15 Tokyo Cap-and-Trade Allowance Allocation Emission Allowance Base-year = ( 100%- Compliance ) 5 years emissions factor Compliance factor by category Ⅰ-1 Commercial buildings, District cooling & heating facilities (plants) 8% Ⅰ-2 Commercial buildings using DHC 6% Ⅱ Factories, etc. 6% Top Certified facilities as: 1/2 or 3/4 of the level Top Level / Near-top level Facility compliance factor

16 Tokyo Cap-and-Trade Trade & MRV Emission Trading: Tradable allowances are limited to the excess reductions over compliance obligations MRV: Monitoring and annual reporting are required. Verification system has established for the program Offset system, Linkage: Renewable, Emission reductions in small facilities, etc. Linkage with the C&T of an adjacent Prefecture

17 Tokyo Cap-and-Trade Trading Reduction Obligation TRADE! CO2 Excess reduction CO2 CO2

18 Carbon Reduction Reporting for Small and Medium Facilities Target: Small & medium emitters not covered by the Tokyo C&T Requirement: Reporting annual CO 2 emissions & their plan for reductions Disclose on the TMG website Over 34,000 facilities are reporting Over 34,000 facilities are reporting including 10,000 volunteers

19 Carbon Reduction Reporting for SMF: Benchmarking Launched Benchmarking Program 22 building-use categories in 7 ratings

20 2. Major Programs for New Builds TMG Green Building Program

21 TMG Green Building Program 1 Rating and disclosure system for new buildings to promote sustainable design Coverage: Newly planned large buildings (over 5,000 sq. m) Covering 40% of new buildings Requirement: Submit sustainable design plan with its ratings Satisfy energy standard of Tokyo

22 TMG Green Building Program 2 Rating and disclosure system for new buildings Category Items Energy Rating: 12 items in 4 categories Based on the TMG guideline Disclosure: Rated results are disclosed on the TMG website Resources Material Natural environment Heat-Island effect Heat load resistance of the building envelope Renewable energy Energy efficient building system (equipments) Efficient i control systems Eco-materials Protection of ozone layers Longer building life expectancy Hydrological cycle Greening (vegetation, landscape, etc.), bio-diversity Atmospheric heat waste Surface of ground and buildings Wind environment

23 TMG Green Building Program 3 Sister Programs Labeling programs based on the GBP Green Labeling Program for Condominiums i (2005~) Energy Efficient Certificate System for non-residential buildings (2010~) Incentive planning and zoning Utilizing the GBP ratings as a prerequisite Prerequisite for the incentive zoning

24 District Planning for Energy Efficiency Launched January 2010 Coverage : New developments with total floor area >50,000m 2 Obligations: Submission and Disclosure of the planning information on energy conservation 180 days prior to the building permission application Disclosure: Planning information is disclosed by TMG

25 District Planning for Energy Efficiency (2) For Deeper Green Solution Renewable Energy District Heating &Cooling Deeper Green Measures in Buildings Beyond A Building District Energy Plan Earlier in the Planning Stage Approaching both Supply and Demand sides of Energy Disclose the Information and Promote

26 3. Achievement

27 Tokyo Cap-and-Trade Remarkable Results In total23% t Reduction from the base-year emissions Cf. Their obligated reduction: 6 % or 8% 93% of the covered facilities reduced more than the obligations

28 Tokyo Cap-and-Trade Improvament in BEE MJ/m2

29 Tokyo Cap-and-Trade Remarkable Results: Measures Taken Category # of measures Examples AIr Conditioning & Ventilation Lighting, other power use equipments 1,602 System Upgrade, tempreture-humidduty control, Control of air intake... 1,436 Introduce Hf, LED, low-eenrgy guidelight, sensors for controlling, high efficient transformer... Heat source 897 System Upgrade, Introduce inverters, Hot water, water supply, refregerator General management 302 Introduce water-saving toilet, upgrade refregerators, vending machines Tenant inclusion(joint EE team, data sharing...), tunings,control system upgrade

Peak Power Consumption (from 1 July to 31A Aug.)

35 Preparedness for the Power Crisis Cumulative results and efforts in buildings responding to Tokyo cap & trade and other initiatives helped to cut power consumption Green Buildings Already introduced d measures Prodctivity & Confortability Business Continuity Already have action plans Already have communications
