summary	Our awareness of the earth's depleting resources has directed focus towards biomaterials, which can be extracted sustainably and biodegraded after use. Current fabrication of biomaterial structures is still restricted in strength and geometry, limiting its use in construction. This paper presents a novel two-phase multi-material fabrication process to create mycelium composite structures of higher porosity and complexity with speculated improvements in strength. First, cellulose pulp inoculated with mycelium is extruded. Then, each layer is filled by a secondary supporting material. This material, in the form of a gravel- and sand-slurry, acts as an inhospitable medium steering mycelial growth, additionally improving aeration to produce stronger structures. After an intermediate growth period, the secondary material, reusable in a closed-loop production model, is removed to reveal the fully-grown mycelium structure. The paper reports on each of the three aspects: the fabrication process, material experimentation of primary and secondary substrates, as well as geometry of varying porosity and performance.

title	Towards a framework for emotional tactile interaction design

summary	This study aims to explore the possibility of maintaining intuitive behavior patterns and the most natural relationship coming from physical touch between human and object as interaction behaviors in interaction designs. Such an interaction will convey affection while providing brand new applications and innovative experiences offered by digital technology. Interactive behavior is natural, but the experience of affection is novel is the core idea of the interaction design in this study. The study aims to use a familiar artifact in daily life as the main carrier and embed technology in them and activate them, enabling them with sensitive sensing ability. With such an ability, the interaction between human and objects is thus sensed in a pattern of touch, which itself is affective and interactive. Interactions at the proper time can be provided as feedback, allowing users to experience emotional interaction. Through the analysis of the authors six interaction design projects and experiments over 10 years, the design process and framework for emotional tactile interaction design in using a familiar artifact is proposed.

title	Land Use Type Allocation Informed by Urban Energy Performance: A Use Case for a Semantic-Web Approach to Master Planning - A USE CASE FOR A SEMANTIC-WEB APPROACH TO MASTER PLANNING
doi	https://doi.org/10.52842/conf.caadria.2021.2.679

summary	Cities are growing fast and facing unprecedented challenges as urban populations grow and resources are becoming scarce. A citys master planning involves a series of decision-making processes and requires knowledge from various domains. Urban planners are seeking computational support. We present a use case of land use type or building function allocations informed by urban energy performance as a pilot demonstrator for a semantic-web approach to these challenges. The software used for energy performance assessment was the City Energy Analyst. Using a quarter in downtown Singapore as an example, the results indicated 70% to 80% residential supplemented by other land use types favours efficient use of district cooling systems and photovoltaic panels. Urban planners may use the results to narrow down the search space of land use type ratios for the selected mixed-use area in Singapore. The use case serves as a pilot demonstrator for a broader research scope, the project Cities Knowledge Graph. To support master planning, the project aims to build an extendable plat-form to integrate more datasets and evaluation software for various urban qualities and domains.
