In order to pave the way for the best possible building energy and GHG emissions abatement in our four priority regions, the GBPN runs a global research programme. 

The GBPN conducts global research and analysis to advance knowledge and expertise that can initiate and foster the implementation of ambitious policies in the regions. Our global research aims to: 

  • Support the rapid development and implementation of stringent energy performance codes and supporting policy-packages for new and existing buildings;
  • Model, define and monitor progress toward achieving the abatement potential of the building sector;
  • Identify best-practice policy pathways which serve as benchmarks for regional policy innovation;
  • Provide the industry with the best reliable data on building energy and policy performance;
  • Develop strategies for capturing the GHG abatement potential of the entire building value chain and the significant co-benefits of broader green building and sustainable city policy;
  • Maximising the learning between regions.

Creating knowledge and data to support the Deep Path

The Global Research Programme aims to create knowledge and data that support the development of practical roadmaps that can move each of the regional jurisdictions towards the Deep Path of energy savings in buildings to achieve more than 2.2 Gt CO2 abatement globally by 2030 and 3.2 Gt CO2 by 2050 compared to today’s carbon emissions.

A ‘deep path’ of energy and GHG emission reductions and savings is possible at the global scale by 2050 if our four-priority regions unlock their mitigation potential.
Achieving this abatement potential requires today’s state of the art building energy performance codes and complimentary policies to be optimized in regional jurisdictions towards net zero energy targets for new buildings and deep renovation for existing buildings. This translates into a strategic definition of best-practice actions that encourage adoption of policy frameworks for achieving:
  • Net zero energy performance in new buildings;
  • Increased rate of deep renovation of existing buildings.

Research priorities

Each of our four regions is starting at a different point, so the development of each regional roadmap is informed by global research on common priority issues. Our research on state of the art policies towards Net Zero energy for New Buildings and Deep Renovation of the Existing Building Stock, will cover the following topics:

  • Financing and co-benefits
  • Performance codes, data and mandatory rating and disclosure policies
  • Policies for integrated renewable energy in buildings developments
  • Compliance with mandatory performance requirements

In the context of climate change mitigation, the abatement potential is the amount of mitigation that could be reduced over time. [Source: IPCC]

Deep Renovation or Deep Energy Renovation is a term for a building renovation that captures the full economic energy efficiency potential of improvements. This typically includes a focus on the building shell of existing buildings in order to achieve very high-energy performance. The renovated building consumes 75% less primary energy compared to the status of the existing building before the renovation. The energy consumption after renovation for heating, cooling, ventilation, hot water and lighting, is less than 60 kWh/m2/yr. (Definition often used in Europe) [Source: GBPN, 2012]

NZEB are buildings that over a year are neutral, meaning that they deliver as much energy to the supply grids as they use from the grids. Seen in these terms they do not need any fossil fuel for heating, cooling, lighting or other energy uses although they sometimes draw energy from the grid. [Source: IEA (Laustsen J.)
