In a prior study entitled “Mapping of Existing Energy Efficiency Standards and Technologies in Buildings in the UNECE Region”, the UN Committee on Housing and Land Management (CHLM) and the Committee on Sustainable Energy (CSE) commissioned a comparative study on building standards in the UNECE region. The current report follows up on this by analyzing the actual prevalence of specific types of energy-efficient technologies in the buildings sector in the UNECE region, along with the levels and types of public policy interventions supporting their implementations. The study objectives are to evaluate UNECE countries vis-à-vis their adaptation of these technologies, identify implementation gaps and possible causal barriers, and recommend country-specific rectifying actions. We gathered data for this study mainly through desktop research of both internet and print media, including official governmental communiques, NGO-published reports, academic publications, energy databases, and public news outlets. We validated and further augmented these data sources through consultations with various subject-matter experts and organizations.

Chapter 1 documents the objectives and scope of this study. The methodology used, as well as perceived limitations is also detailed. In Chapter 2, the authors focus on the energy used in the building during its operational life, and relevant existing energy efficiency technologies in six broad categories: building envelope (insulation and glazing), space heating, air conditioning, water heating and cooling, appliances, and lighting. These technologies are mapped in relation to existing building standards. Chapter 3 documents a review of the application and adaption of the relevant technologies, nation-level assessment, and the gap analysis. Gaps are identified and analyzed with respect to several perspectives, including: knowledge, technical, regulatory, institutional, and financial. The authors end with Conclusions and Recommendations, which are based on the mapping and gap analysis, focusing on priority actions countries in the UNECE region should take to increase the uptake of technologies to enhance energy efficiency in buildings. Recommendations include, but are not limited to, aspects surrounding policy and legislation, investments and financial incentives, technology adaptation, and capacity development.
