This paper reviews empirical data from evaluations of the influence of residential energy efficiency retrofits on indoor environmental quality conditions and self-reported thermal comfort and health. Data were extracted from 36 studies described in 44 papers plus two reports. Nearly all reviewed studies were performed in Europe or United States. Most studies evaluated retrofits of homes with low-income occupants. Indoor radon and formaldehyde concentrations tended to increase after retrofits that did not add whole-house mechanical ventilation.
This paper aims to review the state of the art technologies for the energy efficiency within the hospitals sector. Hospitals are liable for an unstable amount of energy demand and joint emissions, because of their 24/7 nature of operation and hence resulting larger energy consumption than a typical commercial building. Additionally, they need high quality and warranted supplies of electricity. Due to increased energy demand and therefore the depletion of existing fossil fuel based sources, it is required to use the energy more efficient.
Naturally ventilated buildings have been worldwide increasingly welcomed, given the current global awareness toward environmental sustainability, indoor health-quality and renewable energy. As Natural Ventilation (NV) performance relies on building design and interaction with the local environment, its potential benefits are not always easy to take advantage of, and thus sets up a vital field of study. This paper provides an overview of investigations on the subject by collecting researches focused on thermal comfort, energy efficiency and indoor air quality.
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.
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.
