AbstractSolar access plays an important role in everyday lives of residents such as thermal comfort, lighting and various household activities. Guidelines and standards for the provision of sunlight have been formulated in the past few decades in low-density living environment. In sub-tropical high-density living environment like Hong Kong, there is generally a lack of associated guidelines and standards and it has become a growing concern for better provision of sunlight to residential units. Residents’ preference of solar access is very important to the formulation of standards for solar access and daylighting, as well as urban planning and building design. The present paper presents the results of a questionnaire survey regarding residents’ preference of solar access in terms of time, amount, place, and purpose of the exploitation of sunlight in the winter months in Hong Kong, as well as an exploratory factor analysis (EFA) which examines the influence of environmental parameters on residents’ preference. Results indicate that over 50% of the respondents surveyed were satisfied with the current situation of solar access in their households. Nevertheless, about 20% of the respondents still felt unsatisfactory about solar access of their flats. Sunlight penetration into their households in the morning was preferred by over 50% of the respondents. Respondents were in favour of solar access in the morning and expected about 2-3 hours of solar access in general. The EFA results indicate that observed microclimatic parameters such as relative humidity and solar radiation are the dominant factors influencing residents’ preference of solar access and closely followed by visual elements of residents’ subjective feelings about their flats. The consideration of microclimatic parameters is therefore important to the formulation of design standard and guidelines. Policy-makers, as well as planners and architects, should therefore take the findings into account when establishing appropriate guidelines and standards in order to provide residential units with better sunlight environment.
