Corporate real estate management (CREM) is complex due to an increasing number of real estate (RE) added values and the tensions between them. RE managers are faced with trade-offs: to choose a higher performance for one added value at the cost of another. CREM research mainly deals with trade-offs in a hypothetical sense, without looking at the characteristics of the RE portfolio nor the specific context in which trade-offs are made. The purpose of this paper is to further develop the concept of real estate value (REV) optimisation with regard to tensions between decreasing CO₂ emissions and supporting user activities.

Mixed method study. REV optimisation between user activities and energy efficiency for police stations in the Netherlands built between 2000 and 2020 is analysed. This is complemented by interviews with an RE manager and senior user of police stations and analysis of policy documents.

The characteristics of the police station portfolio indicate no correlation between user activities and energy efficiency for the case studied. This is complemented by interviews, from which it becomes clear that there was in fact little tension between supporting user activities and energy efficiency. The performances of these two different added values were optimised separately.

This study combines different scales (building and portfolio level) with different types of data: portfolio analysis, document analysis and interviews. This creates a comprehensive image of whether and how the Netherlands police optimised the two RE values.

The present study, based on a comparative analysis of several historic houses in Shiraz, presents a new perspective on uncovering the role of the social lives of homeowners in the formation of the spatial configurations of their houses.

Twelve plans were selected and analyzed using space syntax techniques. The spatial characteristics were compared mathematically using integration, intelligibility and axial synergy.

The results of the research showed that spatial configurations reflected the social identity of their homeowners as well as their cultural and private beliefs. The results further highlighted the syntactical differences between different types of one courtyard houses, two courtyard houses and three courtyard houses. While privacy was maintained across all housing layouts, centralized one-courtyard typography had the highest synergy while the three-courtyard typology had the highest intelligibility.

This research advances the use of space syntax approach in the design of contemporary housing by recognizing the socio-cultural values of its occupants.
