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.

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 report presents the results of a state-by-state analysis of the potential energy and cost savings from improving compliance with building energy codes to 100 percent from current levels. The report also examines 45 statewide compliance evaluation studies, providing a summary of evaluation methods and key findings. Evidence in most states indicates that staggering rates of non-compliance, as high as 100 percent in some jurisdictions, have eroded the gains from energy code development and adoption.

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.

Focusing on the voluntary LEED and ENERGY STAR environmental certification schemes in the United States, we investigate whether price premiums exist across all building value categories or are localized to specific value segments. We find that the largest value building segment does not demonstrate any price premiums, while the smallest value categories do. The concentrated supply of eco-labeled offices in large, high-quality buildings likely contributes to this phenomenon.

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.
