Fuel-Efficient Driving

How to support fuel-efficient driving? (2018) by Ekaterina Gilman et al. published in IET Intelligent Transport Systems doi: 10.1049/iet-its.2016.0280  There are many ways in which the emissions from road transport can be reduced. An appropriate initial choice of vehicle, together with suitable maintenance, may be thought of as a strategic decision. This paper concentrates on tactics and operation; issues of route selection and driver behaviour, and in particular the technical systems available to inform them.  The authors acknowledge that cultivating sustainable change in driving behaviour is difficult, and that this needs to be reflected in the design of any form of technical assistance. (Readers may notice points in this study which are analogous to issues in other areas of energy saving, such as domestic heating). The paper reviews the literature on driving assistance systems, and notes some general points. Feedback to the driver on the fuel saving achieved is usually of great inter…

Quantitative application of Infrared Thermography

Some earlier posts referred to the importance of improving the thermal efficiency of existing buildings in order to reduce carbon emissions associated with heating.
Retrofit 2050 concentrated on methods of measuring the thermal performance of buildings when the thermal properties of the materials used are unknown.
Retrofit of buildings: citations and extracts referred to recent work on improving methods of thermal measurement.
Energy Efficiency in Buildings provided links to energy performance standards.
Many papers on thermal measurement focus on assessing the U-values of existing structures. Standard methods involve the use of both temperature and heat-flow measurements and are typically time-consuming and demanding. Effort has been directed to reducing the difficulties and producing quicker results, in some cases by eliminating the need for heat flow measurement. Reducing measurement time without loss of accuracy remains a goal.
The infrared thermography technique (ITT) has been widely…

Electric Cars and On-street Charging

The link between ownership of electric cars in the UK and the provision of charging facilities is explored in the following articles.This is Money, 23 February 2017, reported that the Office for Low Emission Vehicles (OLEV) made £1 million available to fund installations during the current financial year and an additional £1.5 million for 2017/18. Residents who want one of the twin charge points added on their street need to ask their local authority to take up their case, funding then being allocated on a first-come first-served basis. See: A BBC news article on charging EVs (February 2018) opened with the question “What if you live in a flat?” The option of asking the local authority to install a street charging point is described, OLEV having set aside £4.5m to support such applications over the next two years, and offering to pay up to 75% of the costs of installation, to a maximum of …
