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.
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.
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.
This paper introduces the major state-level regulations and policies for improving energy efficiency in buildings. The purpose of the review is to discuss the challenges and issues in policy implementation and the latest trend in adopting innovative instruments. The implementation of customer efficiency programs increasingly incorporates non-price instruments to encourage participation and deep savings. States pay attention to not only code adoption and update but also compliance and evaluation.
This study examines the sources of evidence that influence decision-makers who design or develop office buildings, and aims to explain why some managers engage more in evidence-based practice (EBP) than others. A mixed methods approach is conducted that combines quantitative results from 187 senior managers in the built environment and qualitative data from 18 interviewees. The respondents evaluated the use and trustworthiness of different sources of evidence, followed by an assessment of practitioners’ adoption and understanding of EBP.
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.
This paper outlines the approach and the cost-effectiveness potential for designing and retrofitting residential buildings to be energy-efficient in Bahrain. The analysis is focused on residential buildings since these buildings consume over 48% of the total electricity used in Bahrain. The optimization analysis has the benefit to assess both at the individual building and the national building stock levels, the potential of the application of currently proven measures and technologies to improve the energy efficiency of the building sector in Bahrain.
Energy efficiency policies have the unique capacity to contribute to a more sustainable energy future at an economic net benefit even when co-benefits are not included in the evaluations. The purpose of this paper is to present quantitative and comparative information on the societal cost-effectiveness and the lifetime energy savings of all light eight building energy efficiency policy instruments.
Energy Efficiency Retrofit (EER) of existing buildings is a key program for improving building energy efficiency in northern regions of China. This paper presents a methodological framework to conduct an economic cost-benefit analysis for EER projects, based on the calculation of costs and benefits over life cycle. By conducting a case study of a retrofit project located in Huixin Western Street Residential Area, Beijing, China, this research empirically examines its economic sustainability.
This report is the first report of the ‘Energy Savings 2030’-project which seeks to help the Coalition for Energy Savings to produce a robust and timely input to the 2030 policy discussion. It brings together and summarises recent empirical evidence on costs and benefits of energy efficiency measures. The evidence gap in terms of reliable ex-post data is well known. In the majority of cases results from ex-ante modelling studies inform the debate. The research carried out for this report confirms the persistent gap in publicly available ex-post evaluations of energy efficiency programmes.
The Energy Efficiency Financial Institutions Group (“EFFIG”) identifies the need to engage multiple stakeholder groups, scale-up the use of several financial instruments within a clear and enforced “carrot and stick” legislative framework. This report identifies a number of approaches and instruments that have proven to encourage investments and multiple market barriers that stand in the way of an energy efficient Europe.
The EU and Australia have instituted significant new public policies to promote energy efficiency in the “built environment.” Many of these public policies were motivated by the same concerns that led to the pioneering voluntary initiatives of Green Building Councils (especially the LEED design certification program) and the U.S. Department of Energy’s ENERGY STAR system for buildings. However, policy initiatives on both continents are relatively new, have been recently modified, and are yet to be finalized.
