The study conducted in this paper is focused on a predominantly residential area of the City of Ljubljana—Koseze, which is characterized by generally favorable (bio)climatic conditions. Nonetheless, thermal satellite images showed that residential neighborhoods within the Koseze district display unexpected variations in summer temperatures. This observation called into question the benefits of existing bioclimatic features and indicated the need to investigate and compare two neighborhoods with similar urban parameters, with the aim to identify morphological differential characteristics impacting urban heat island (UHI) intensity. By applying the study methodology based on a literature review, surveys of key precedents, detailed mapping in two Koseze locations, in situ measurements, observations and recordings, thermal imagery, and the analyses of statistical data, as well as by defining the four main categories of morphological urban parameters—structure, cover, fabric and metabolism, it was concluded that both neighborhoods have common morphological elements mitigating the UHI effect. Additionally, it was found that the neighborhood with higher UHI intensity has several less favorable features, such as busier roads, larger surface of parking corridors, and the existence of underground parking space. The traffic as an element of urban morphology hence represents the main cause of differences among UHI levels in the two Koseze neighborhoods.

Lack of financial resources has become one of the main issues in fulfilling social and physical needs in urban development. The declining levels of public resources make the collaboration between public and private investors necessary. When facing the challenges of ageing population, shared investment may contribute to the appropriate development of sheltered housing to meet the goals of spatial planning as well as certain standards at the level of urban design. By ensuring appropriate living conditions for all generations such urban PPP projects may contribute to the fulfilment of the public interest. The paper presents practice of PPP implementation in Ljubljana, Slovenia, where local authority with the collaboration of private partners ensured more than 400 sheltered apartments in the last years. Examples show the extension of the idea from the 70s onwards in finding new models of housing for the aging population. The development of new models can be a good example of strengthening the cooperation between public and private partners in the field of urban development practice.
