| Summary/Abstract |
Axon et al., (2012) argue that maximizing the potential for energy efficiency and demand reduction in tenanted commercial properties requires a "building communities" approach. This paper develops and extends Axon et al.'s proposed framework in two ways. First, by extending its applicability from tenanted to owner-occupied properties. Second, by situating it within the literature related to organizational culture, occupant behaviours, and technology adoption. The paper begins with a brief review of the existing research on people, energy and commercial buildings. This literature tends to address either organizational choices, or occupant behavior, but it rarely crosses the analytical boundaries between these two groups. The paper then explores these different levels of analysis within a 3Cs - "concern, capacity, and conditions" - framework, which was developed to describe and distinguish organizational responses to an energy crisis. The combination of the "building communities" and 3Cs frames reveals gaps and grey areas between organizational culture, occupant behaviour, and technology adoption where further conservation opportunities may lie. These understudied areas suggest that there may be "social potential" for change that is between and beyond the frames used by previous research in the field.

| Summary/Abstract |
Much focus is put on measures to improve the building envelope system performance to reduce the impact of the building sector on the global environmental degradation. This paper compares the potential of building envelope improvements to those of a change in the occupant's behavioural pattern. Three cases of improvements together with a base case were analysed using exergy analysis, because the exergy concept is useful to understand the underlying processes and the necessary adjustments to the calculation of the heat-pump system. The assumptions for the occupant behaviour were set up based on our field measurements conducted in a dormitory building and the calculation was for steady-state conditions. It was found that the potential of occupant behavioural changes for the reduction in exergy consumption is more affected by the outdoor temperature compared to building envelope improvements. The influence of occupant behaviour was highly significant (more than 90% decrease of exergy consumption) when the temperature difference between indoors and outdoors is small, which is the case for long periods in regions with moderate temperatures during summer and/or winter. Nevertheless, both measures combined lead to a reduction from 76% up to 95% depending on the outside conditions and should be the final goal.

| Summary/Abstract |
Much of the social housing stock in southern Europe is obsolete in energy terms, with users who also present very specific socio-economic profiles requiring in-depth study. Proposals for this type of housing stock of current energy retrofitting policies, based on standardized user patterns, will only contribute to increasing the ‘performance gap’ between real and estimated consumption.

| Summary/Abstract |
These days the number of projects trying to urge a change in the occupant's behaviour towards a sustainable one is increasing. However, still less is known about the effect of such measures. This paper describes the findings of two investigations, a field measurement and an Internet-based survey, both including the dissemination of information about strategies for a high level of comfort without much energy usage. The focus was on the ability to quantify the effect of such measures on the heating and cooling behaviour. As a result, those who participated in a workshop were more likely to change their behaviour than those who received an information brochure only; whether this was due to the method employed or the type of participants could not be ascertained. However, the workshop participants reduced their cooling device usage by up to 16%. The concept of exergy was used to show how this reduction affects the exergy consumption of the cooling device, because it enables us to consider the qualitative aspect of energy as a quantity to be calculated. This showed that the exergy consumed by the workshop group was reduced by up to 20% comparing their behaviour before and after the information dissemination.

| Summary/Abstract |
A conceptual framework for occupant behaviour as a driver of fuel poverty is presented, comprising: housing and use of the home; heating and energy arrangements and thermal comfort; household structure and dynamics; health and well-being; household finances; and social activity and relations. This framework informs longitudinal analysis of movements into and out of fuel poverty among households in deprived communities in Glasgow. Household surveys across ten years yielded a longitudinal sample of 3297 cases where initial and subsequent fuel poverty status was recorded using an experiential measure. A third of households changed their fuel poverty status over time: 18% moving out of fuel poverty and 16% moving in. Factors strongly associated with movements into fuel poverty included: being a single parent (OR 2.27); experiencing a mental health problem (OR 2.74); and remaining out of work (OR 1.89). Movement out of fuel poverty was less likely among those with infrequent family contact (OR 0.55) and who moved home (OR 0.66); home improvements had no effect upon the experience of fuel poverty. It is argued that the policy problem should be considered one of ‘warmth and energy deprivation’, accompanied by a broader interpretation of vulnerability to as well as from fuel poverty.
