This chapter is part of a research on algorithmic approaches to sustainable urban design. It focuses on the use of computational tools to provide quick and dynamic assessment while planning and discussing interventions in urban areas. The objective is to address the use of algorithmic systems to formulate effective strategies for sustainable urban projects, guided by Transit Oriented Development (TOD) principles. TOD is an urban development model that considers geometric principles and measurable parameters for designing sustainable cities. It advocates the creation of mixed-use neighborhoods within walking distance to a variety of transportation options and amenities, so that basic urban needs are easily accessible. In addition to establish a theoretical framework connecting algorithmic-parametric concepts and geometrical features of TOD, this chapter describes an experimental employment of algorithmic models working on TOD principles, in order to enhance a systematic and dynamic testing and subsequent argumentation for sustainable urban projects.

This chapter examines the requirements for heritage spatial representation to suggest design guidelines for these interpretive environments. It focuses on the concept of play and its role in the construction of place, or meaningful space, by means of rituals and regulated actions. Examples are given not only from virtual heritage applications but also from other digital works, especially video games, whose implementations to foster user engagement must be regarded as possible key strategies towards creating virtual places in their broadest sense, that is, spaces of multiple possible meanings.
