Abstract

Around the world, engineers, architects and policymakers have been exploring ways to deliver highly efficient buildings whose reduced energy demand is satisfied by clean, renewable energy. Building off of the broader concept of a green or sustainable building, the concept of the “net zero building” focuses on the energy dynamics and performance of the building. And as policymakers and leaders align toward the net zero concept, the focus on achieving deep energy efficiency has centered on integrated technologies as well as ways to connect buildings to the natural environment.
Since 2010, United Nations Environment (UNEP) has produced annual Emissions Gap Reports based on requests by countries for an independent scientific assessment of how actions and pledges by countries affect the global greenhouse gas emissions trend, and how this compares to emissions trajectories consistent with the long-term goal of the United Nations Framework Convention on Climate Change (UNFCCC). The difference has become known as the emissions gap.
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.
EU member states have been encouraged to introduce energy efficiency obligation schemes (EEOS) to help meet energy saving objectives. As a result, there are now 15 EU EEOS in existence, compared with just six prior to the introduction of the 2012 Energy Efficiency Directive. At the same time, the long-standing EEOS in Denmark and the UK have faced challenges because of concerns over increasing costs. This paper considers the role of EEOS in current and future EU and national policy. Firstly, this paper sets out in more detail the place of EEOS in EU energy policy.
This paper provides an overview of the Malaysian Energy Efficiency regulatory framework as well as current financing and incentive mechanisms available to the building sector. The review has found that some of the existing financing schemes have been successful while others could leverage on other existing schemes to improve its effectiveness. The review will explore the strengths and gaps of the available schemes and will propose some ways to increase the uptake up rate of the schemes.
The work carried out by Copenhagen Economics for the Renovate Europe Campaign broke new ground in the debate around the benefits of investing in energy efficiency and has, in several ways, advanced the EU agenda in this topic. In executing the contract for us, Copenhagen Economics were professional, impartial and eloquent. I would unhesitatingly use their services again.
In this study, we analyze the demand for green office building features among office tenants in the United States. An online survey of a random sample of office tenants in 17 major U.S. markets is employed. Respondents provided their perspective on green buildings and their willingness-to-pay (WTP) for green features. They have the highest WTP for improved indoor air quality and access to natural light. The results show that public firms, along with those in the energy and information technology industries are most likely to pay for green-labeled buildings.
