The Economist Intelligence Unit (EIU) report "Achieving scale in energy-efficient buildings in India: A view from the construction and real estate sectors" commissioned by the GBPN explains the challenges and opportunities of investing in energy efficiency in buildings in India.
A report from the Economist Intelligence Unit (EIU), commissioned by the GBPN finds that while India’s commercial building sector has blazed the energy-effiency trail in the building sector, achieving significant scale will depend on efficiency measures becoming standard practice in the commercial middle market, retrofit and, particularly, the residential building segment.
Executive Summary
GBPN conducted a study on the factors affecting the use of ESCO models for the retrofit of existing buildings in China, identifying current barriers to the development of the Chinese ESCO market, while also researching best-practice examples of ESCOs globally and investigating the feasibility of introducing those examples to China.
This report assesses the extent to which it would be feasible for the non-residential building sector as a whole, and for individual building forms, to achieve net zero energy and/or greenhouse gas emissions by 2050.
The potential strategies to reach this goal that are analysed in this study include:
Building energy efficiency is an important strategy for reducing greenhouse gas emissions globally. In fact, 55 countries have included building energy efficiency in their Nationally Determined Contributions (NDCs) under the Paris Agreement. This research uses building energy code implementation in six cities across different continents as case studies to assess what it may take for countries to implement the ambitions of their energy efficiency goals.
In order to achieve long-term targets for energy savings and emission reductions, substantial savings will be needed from existing buildings. For example, a recent analysis for the USA examines aggressive strategies to cut carbon emissions in half by 2040 and finds that in order to achieve this emission reduction target, more than half of existing buildings will need comprehensive energy efficiency retrofits. Germany is targeting an overall primary energy consumption reduction of 50% in 2050 including increasing building renovation rate to 2% per year.
Key messages 1. The Buildings sector of today has an oversized ecological footprint. The buildings sector is the single largest contributor to global greenhouse gas emissions (GHG), with approximately one third of global energy end use taking place within buildings. Furthermore, the construction sector is responsible for more than a third of global resource consumption, including 12 per cent of all fresh water use and significantly contributes to the generation of solid waste, estimated at 40 per cent of the total volume.
It is clear that city must be part of the solution if an urbanizing world is to grapple successfully with ecological challenges such as energy depletion and climate change. A system dynamics model was developed in this study using STELLA platform to model the energy consumption and CO2 emission trends for the City of Beijing over 2005–2030. Results show that the total energy demand in Beijing is predicted to reach 114.30 million tonnes coal equivalent (Mtce) by 2030, while that value in 2005 is 55.99 Mtce, which is 1.04 times higher than the level in 2005.
