IBED

International Building Emission Dataset (IBED)

A multi-regional dataset aims to monitor energy trends, emissions mitigation, and building stock on a global scale.

IBED was initially proposed by Dr. Minda Ma in 2021, and now it is a project led by Lawrence Berkeley National Laboratory(LBNL, operated by UC Berkeley for U.S. DOE), Tsinghua University, and Chongqing University.

About IBED

We are pleased to announce the release of a public version of our dataset, which is accessible at http://ibed.world. Our dataset is established based on the IEA database, which has clear distinctions between the end uses relevant to residential and commercial energy activities in its energy balance sheet.

To ensure the reliability of our database, we used the IEA dataset as the primary reference to compile comprehensive and trustworthy data tables for each carbon-emitting country. For major emitters such as China, the United States, and India, we accounted for and calibrated the building energy consumption data and the corresponding carbon emissions data based on the baseline dataset. For other carbon-emitting countries, we collected, cleaned, and validated survey reports and statistical results from regional governments and research institutions, which were then integrated with the baseline dataset to build a unified and standardized database.

PyLMDI

Python-LMDI: a tool for index decomposition analysis of building carbon emissions

A timely analysis for carbon emission reduction in buildings is an effective global response to the crisis of climate change. The logarithmic mean Divisia index (LMDI) decomposition analysis approach has been extensively used to assess the carbon emission reduction potential of the buildings sector. In order to simplify the calculation process and to expand its application scope, a new open-source Python tool (PyLMDI) developed in this article is used to compute the results of LMDI decomposition analysis, including multiplicative and additive decomposition. Users can quickly obtain the decomposition result by initializing the input data through a simple class data structure. In addition, the carbon emissions from commercial buildings are used as a numerical example to demonstrate the function of PyLMDI. In summary, PyLMDI is a potential calculation tool for index decomposition analysis that can provide calculation guidance for carbon emission reduction in the buildings sector. The data and codes for the numerical example are also included.
