Scope of ISO 16745‐2015

• The requirements for determining and reporting a carbon metric of an existing building, associated with the operation of the building.

• sets out methods for – the calculation,– reporting, – communication, and – verification

• of a set of carbon metrics for GHG emissions arising from the measured energy use during the operation of an existing building, the measured user‐related energy use, and other relevant GHG emissions and removals.

Scope of ISO 16745‐2015 (continued)

• not include any method of modeling of the operational energy use of the building

• not an assessment method for evaluating the overall environmental performance of a building or a building‐rating tool

• not include value‐based interpretation of the carbon metric(s) through weightings or benchmarking.


What is common carbon metric of building?(ISO 16745)

Carbon metric• sum of annual greenhouse gas emissions and removals,

expressed as CO2 equivalents, associated with the use stage of a building

• measured by kgCO2e/year.

Carbon intensity• carbon metric expressed in relation to a specific

reference unit related to the function of the building• measured by

– kgCO2e/m2/year, – kgCO2e/occupant/year or etc.

Calculation of of CCM(ISO FDIS 16745)

: the emitted mass of GHG expressed as kg CO2 equivalent per kg emission: the delivered energy for energy carrier ci,: the energy produced onsite for the energy carrier ci, : the GHG emission coefficient for delivered energy carrier ci : the GHG emission coefficient for on‐site energy carrier ci

ISO16745: Example of System Boundary

Only have to measure delivered energy and generation on site,based on bills, Invoices, provider reports and contracts, etc.

Anybody can calculate Carbon Metric.


Required to be measured

NOTRequired to be measured

System boundary of CCM(ISO 16745)

• Carbon metric 1 (CM1) – the sum of annual GHG emissions from building‐relatedenergy use;

• Carbon metric 2 (CM2) – the sum of annual GHG emissions from building‐ and user‐related energy use;

• Carbon metric 3 (CM3) – the sum of annual GHG emissions and removals frombuilding‐ and user‐related energy use, plus other building‐related sources of GHG emissions and removals.

CM quantification

CM study report

Independent ThirdParty verification ? CM claim

CM disclosure report CM declaration

NO

YES

Two types of communication

• a Carbon Metric declaration• a Carbon Metric Claim


Possible use of ISO 196745

• The carbon metric may be used for a variety of purposes, which can include internal or external benchmarking, public information, property evaluation, policy information asset evaluation, etc

• Benchmarking for;– Property management strategy– Investment strategy (short listing of targets)– Energy management service contract– Post occupancy evaluation– Education etc.

• Baselining– Cap and Trade Program (Tokyo Metropolitan government)

• Monetising– International carbon trading (CDM in building related sectors)
