- Numerous field studies conducted in different locations have demonstrated that comfort conditions vary due to adaptation to the local climate. This study aims to investigate how preferences for the indoor environment change when the climate context changes and how thermal history influences comfort conditions in a new thermal environment. A new halls of residence complex in the south of England, housing occupants from various climatic regions, is used as a case study. Two thermal comfort surveys were conducted in October and December 2015 (N=53 residents) within the first three months of the occupants. Air temperature and relative humidity measurements were collected during this period. Results show a range of comfort temperatures of over 10°C across the study period. The first survey (October) found no significant difference between residents when grouped by previous climate of residence. The second survey (December) found that the mean comfort temperature for residents from the UK had dropped by 1°C, despite an unseasonably warm winter, and mean comfort temperatures for residents from other climates remained the same. This could be an indication of psychological adaptation whereby residents accustomed to the UK climate expect cooler temperatures moving from October to December and thus come to prefer this.

- Post-occupancy evaluation (POE) is a process that can reveal the interrelations between key building performance factors and successfully integrate indoor environmental quality, thermal comfort, functionality, environmental strategy and occupants' satisfaction. POE has become a prerequisite for several building certification systems and it is often presented as a method to improve the commissioning of buildings and as a user experience feedback mechanism. This paper is based on a POE undertaken through stages at the University of Southampton Mayflower Halls of Residence complex. The first stage included the evaluation of occupant satisfaction, indoor environment quality and energy use. Results from temperature and relative humidity monitoring and an online POE questionnaire were analysed in the context of energy use, thermal comfort and building controls' functionality. The second part of this study monitored the air temperature in a sub-sample of 30 rooms where the residents participated in a thermal comfort survey with a "right-here-right-now" questionnaire and a portable instrument that monitored air temperature, relative humidity, globe temperature and air velocity in the rooms. This paper presents the results of the POE and discusses approaches for the improvement in the buildings' energy performance and the environmental conditions in the living spaces of the students. Results suggest that current use of controls is not always effective, with implications for the buildings' energy use. Large variability was found in occupants' thermal perception and preferences, which points to a need for occupant-centric solutions. In this study, POE is approached as a dynamic process that could be used to facilitate the responsive interaction of occupants with building systems and deliver through their engagement high energy performance and comfort.

- Social housing retrofit is often seen as a way to contribute to carbon reductions as it typically encompasses large-scale interventions managed by one landlord. This work investigates the carbon savings potential of a deep retrofit in a local authority owned 107-flat tower block, taking into account the tenants' pre-retrofit heating strategies. Prior to the retrofit, temperature and relative humidity monitoring were undertaken in 18 flats for 35 days. The measurements were then used to develop occupant heating profiles in the 18 homes. Dynamic thermal simulation of the flats pre- and post-retrofit using the identified user heating profiles highlights that for these fuel poverty-constrained flats, the estimated carbon savings of retrofit will be typically half those predicted using standard rules for temperatures in living spaces.Practical application: The findings presented in this paper demonstrate the impact of fuel poverty on the expected benefits from social housing retrofit schemes, providing information relevant to multiple stakeholders: (1) building industry: The study highlights the need to use empirical data in building energy modelling, as typical conditions could be far from representative in social homes (2) Policy makers and social landlords: Targets for CO2 reduction may not be achieved through retrofitting, but the social impact could be much greater and more critical than assumed. The findings under this work help to direct incentives for retrofit schemes towards the social and health benefits achieved.
