全球

为使得GBPN四大重点地区(欧洲、美国、中国和印度)达到节能减排的目标,GBPN正在开展全球研究项目。

全球中心一直致力于研究基准信息和最佳实践,并推动地区内和地区间的知识和经验共享,以便:

  • 支持迅速发展和严格实施的能效规范以及同新建和既有建筑有关的能效政策
  • 建模、确定目标以及监控减排进展
  • 为地区能效政策创新提供最佳能效实践政策参考
  • 为建筑行业提供有关建筑能耗和政策绩效的最可靠数据
  • 制定策略以获得整个建筑物价值链的温室气体减排潜力、发展广义绿色建筑以及可持续城市政策所产生的巨大的共同效益
  • 最大化的促进地区间交流学习

研发知识和获取数据以支持发展“深度途径”

全球研究项目旨在研究和收集建筑节能减排的知识和数据以推动各地区建筑按照“深度途径” 发展,从而在2030年前达到减少2.2 兆吨CO2排放以及2050前达到减少3.2兆吨CO2排放的目标(与当前的碳排放相比)。

正如下图所示,如果我们的四大重点区域如果能够发挥自己的减排潜力,2050年节能与温室气体减排的“深度途径”的目标是能够在全球范围内实现的。

达到这一潜力需要各个地区采用最先进的建筑能效规范和配套政策,使新建建筑达到零能效目标以及对既有建筑物进行深度改造。对最佳实践行动进行战略性识别,并为达到以下的目的要鼓励采纳新的政策框架:

  • 新建建筑零能耗
  • 提高对既有建筑物的深度节能改造比重

研究重点

我们所关注的四大地区处于不同的起点,因此通过对共同存在的重点问题进行研究可为各个地区制定建筑节能减排的路线图。这包括对新建建筑零能耗目标政策和既有建筑物的深度改造进行最前沿的研究,其中涉及以下几个课题:

  • 融资与共同效益
  • 能效规范、数据和强制评级以及披露政策
  • 建筑物可再生能源开发和综合利用政策
  • 强制遵守能效标准要求

Glossary

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

Deep retrofit or Deep Energy Retrofit implies replacing existing systems in a building with similar ones that are of higher quality and performance, which leads to a better energy performance of an existing building. The primary energy consumption includes energy used for heating, cooling, ventilation, hot water, lighting, installed equipment and appliances. After the deep retrofit the buildings consume 50% less primary energy compared to the status of theexisting building/s the retrofit (Definition mainly used in US). [Source: GBPN, 2012]

Policies mandated to accelerate climate change mitigation and adaptation measures. [Source: UNFCC]

The calculated or measured amount of energy needed to meet the energy demand associated with a typical use of the buildings, which includes inter alia, energy used for heating, cooling, ventilation, hot water and lighting (EU). [Source: EPBD recast, 2010/31/EU]

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.)
