Data Annex

Discover where things stand regarding building energy data quality and availability in our four regions, this report reminds us of how far we have to go before a robust and comprehensive set of building data is in place and provides some recommendations of how we can get there.

Case Study

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. 

Briefing

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 rapid review identified two results extracted from the eight studies (published between 2013 and 2018) that fulfilled our inclusion criteria. Firstly, our analysis identified five common themes across the included studies which provide tentative information for what would be needed to make low carbon residential retrofit/renovation policy work. Secondly, we make an overall observation that the included studies did not provide sufficient evidence or establish conclusive results about the effectiveness of specific low carbon policies compared to other policies.

Energy efficiency (i.e., the ratio of output of performance to input of energy) in office buildings can reduce energy costs and CO2 emissions, but there are barriers to widespread adoption of energy efficient solutions in offices because they are often perceived as a potential threat to perceived comfort, well-being, and performance of office users. However, the links between offices' energy efficiency and users' performance and well-being through their moderators are neither necessary nor empirically confirmed.

Cities in developing countries seldom consider the cost increases that regulations impose on development. To build legal housing, developers must meet a high minimum cost threshold established by mandatory standards. Many standards impose costs on building construction, make them less affordable to low-income households, deprive them access to legally built housing, and fuel the formation of slums.

Rapid urbanization poses a significant challenge of accommodating the poor, particularly in developing countries such as China where affordable housing has only been initiated a few years ago and will continue to be developed in the coming years. Two major considerations in affordable housing programs are cost and time, as the ability to meet the needs of low-income households is the main target of these programs. However, it is not a common strategy to address affordable housing shortage by means of incorporating sustainability features.

Thanks to new insights on the impacts that dwellings have throughout their life cycles, there has been increased attention to retrofitting innovative energy systems (IES) in existing housing. This paper uses an explorative case study design to gain more knowledge about the governance aspects of this under-researched topic. The central research question is: Which factors influence the adoption of innovative energy systems in social housing sites during renovation projects? To answer this question, eight large-scale renovation projects in The Netherlands were investigated.

On an average, India has more than 3000 Cooling Degree Days (CDD). The multifamily public housing being constructed under India’s Prime Minister Awas Yojana (PMAY) is aimed at providing formal housing to the society’s Economic Weaker Section (EWS). It is essential that this housing delivers thermally comfortable in-doors to the occupants. This study mapped the design and construction practices followed under PMAY Urban (PMAY-U) against India’s Residential Energy Building Code, Eco Niwas Samhita (ENS). The metric prescribed in ENS is Residential Envelope Transmittance Value (RETV).
