Climate change is one of the largest threats both for the global economy and the local community. It is predicted that, by 2100, average temperatures could rise as much as six degrees Celsius. The UK is anticipated to become hotter and drier in summer and milder and wetter in winter even under low carbon emissions […]

Further occupant surveys conducted by the group have shown that compromising one aspect of the indoor comfort conditions can lead to a perceived compromising of all other measures of indoor comfort. A survey conducted in June 2005 inside existing offices adjacent to the PV atrium (c in Figure 1) reveiled a significantly worse perception of indoor […]


1960s building in need of refurbishment

In industrialised countries building refurbishment is generally considered to be vital in order to achieve major carbon emission reductions in the built environment. At high latitudes the largest single consumer of energy in buildings continues to be space heating required for creating comfortable indoor conditions. For example, a typical 3 bedroom UK house has, on […]


Carbon dioxide monitoring data

The carbon dioxide concentration levels normally observed in indoor environments range from 350 to 2,500 ppm and are typically between 500 and 1,500 ppm. Current literature suggests that a building’s carbon dioxide concentration can be seen as an indicator for both volatile organic component (VOC) concentration and general indoor air quality. However, the potential to […]


PV facade leading to internal gain

The question of how to qualify and quantify good building performance is not trivial to answer. A well performing building from a carbon footprint perspective may not automatically be well performing in terms of occupant satisfaction (Figure 1). Similarly building performance may be understood quite differently by different groups of building users as ‘performance’ can […]

The group’s research has highlighted that at present environmental control facilities are often not correctly applied, or more usually, incorrectly used due to their complexity or unintuitive mode of operation. It has been shown that there is often lack of interaction between users and their buildings. Façade interaction studies of an office building highlighted rather […]


Building envelope refurbishment

Within the framework of the IDCOP research project a pre-refurbishment tool for assessing buildings was developed (Figure 1). This tool which is termed B-space assesses the energy demand of multi-storey office buildings taking into account occupier comfort. B-space is targeted at asset mangers as main user group. It enables calculation of a building’s carbon footprint […]

Human-made emissions be it from buildings, business, agriculture or transport are now commonly accepted to be the main cause of the global warming trend which is currently being experienced. The Sustainable Energy Research Group is conducting research on climate change issues by assessing future climate impacts in particular in terms of the future performance of […]


The University of Southampton has three permanently grid connected PV systems on its Highfield Campus designed and serviced by the Sustainable Energy Research Group. The installed capacity of these three facilities is about 20 kWp: (a) George Thomas Building – 12.2 kWp atrium (b) Building 2 – 7.2 kWp vertical façade (c) Eustice Building – […]
