BATir Sustainability Research Tracks 1&2 Research Tracks IDSAU framework with 6 thema?c and disciplinary rela?onal tracks § Educa&onal contribu&on + organizing and structuring the development of individual
PhD student’s research trajectories.
2. Design involves research by design & urban design track into building & urban form, infrastructure, density & land-‐use rela&onship at different scales (building, cluster, neighborhood to city & region) & their transforma&ons for developing new concepts, strategies & scenarios for ID (Integrated Design)
1. Theory involves theory-‐building track on the rela&onships between sustainability pillars (3Es – economy, ecology, equity), values and ethics, and their reinterpreta&ons in the design, policy and technological discourses reflected in the prolifera&ng transi&on strategies for enhancing theore&cal underpinnings of ID
3. Planning involves research into the rela&onships between various substan&al sustainability issues, land-‐use change dynamics, mul&-‐level governance, and their policy dimensions for ID & sustainable urban development
BATir Sustainability Research Tracks 1&2
4. Strategic Assessment -‐Indicators / Models
involves research into the rela&onships between different sustainability measurement systems (indicators & indexes) at different scales and their underlying methodological base (LCA, ecological/carbon foot-‐print, embodied energy to eco-‐indicators & externali&es) for developing new integrated models & simula&on methods for ID
5. Infrastructure, Mobility, Transport
involves research into the rela&onships between infrastructures of all kind, mobility, mul&-‐modality, u&li&es (energy, water, gas, communica&on, etc.), transporta&on modes (hard & soP i.e. road, rail, water & air-‐ways; and pedestrian, bicycle, etc.), and the way they influence urban morpholology, and shapes urban forms that require integrated models & simula&on methods for ID
4. Ecology, Climate Change, Ecosystems
involves research into the rela&onships between ecosystem services (par&cularly the urban ones), material and immaterial urban ecologies, urban metabolism, bioclima&sm, in the context of climate change (UHI, HW, etc) in order to develop new integrated design, planning and policy responses

negotiated and designed in a bottom-linked manner. Through its ongoing democratic practice involving a
wide diversity of neighbourhood, city, etc. actors, it improves relations between individuals and
organizations both within and outside the neighbourhood. Processes of SI are steered through socially
innovative governance [Mac Callum, D., et al. 2009]. In this regard, as mentioned earlier, we propose
the establishment of a ‘European Social Innovation Network’. The following illustration shows how the
philosophy of SI through IAD works: it reacts to deprivation or poor service provision, is based on the
mobilisation of local and supra-local resources, and depends for its effectiveness on multi-scalar
governance [Moulaert, et al. 2010].
Illustration 6.2: Dynamics of social innovation

Accessibility to social resources through SI and IAD promotes social inclusion, overcomes spatial
fragmentation, supports capabilities’ acquisition and ameliorates the urban environment towards
cohesion and sustainability. It may stir a renewed interest in social issues at all levels [local, national,
EU], and social cohesion as a worthwhile concern in itself and not only functional to economic
development. In our recommendations, the conceptual and analytical apparatus of SI and IAD [Moulaert,

PhD Title: Integrated design process through triangulated analysis of Urban form, Energy and Bioclimatism for sustainable urbanism PhD Candidate: Séverine Hermand
BATir Sustainability Research Tracks 6
§ Developing a context-specific and scale-sensitive Integrated Design Process (IDP) for sustainable urbanism (SU) through triangulated analysis of urban form (including infrastructure), bioclimatism and energy efficiency in the context of Brussels CR.
§ Within this framework, explore IDP at the level of neighbourhood as the first stage of the research and the district and the city scales are the next two stages.
§ Focus is the design of open space structure in terms of its capacity in regulating the energy performance in Brussels.
§ to develop an assessment framework for unfolding differentiated design, planning and policy responses to facilitate an energy efficient and sustainable urban development in BCR.

§ Our intention behind the choice and the
overlapping of the structural indicators is to keep the complexity of the city’s structure while structuring it in order to understand the mechanisms.

Research Track Development of a set of spa&ally explicit and dynamic indicators for scenarios tes&ng by: • GIS-‐based environmental modeling
(to describe heat flux and water reten&on behavior) and;
• survey and proximity analysis (for accessibility and experien&al/cultural issues);
Research-‐by-‐Design Track In parallel, a research-‐by-‐design stream will be maintained through organizing a series of workshops with key stakeholders for: • the valida&on of the analysis and indicators; • co-‐produce further knowledge on ES and
urban design interac&on; • and shared scenarios development.
Design will thus be used as an integra?ve and interdisciplinary component of the research, but also as a trans-‐disciplinary mode of research involving stakeholder par?cipa?on and co-‐produc?on.
