APPLICATIONS IN SMART AND SUSTAINABLE CITIES by Gabriel Novaes

APPLICATIONS IN SMART AND SUSTAINABLE CITIES Cesar Massaro City Laboratory, Technologies and Urbanism (LCTU/ Conecticidade) Polytechnic School - University of Sao Paulo – Brazil CLUST-ER BUILD

Smart and Sustainable Cities - BIM related applications • On behalf of LCTU/Conecticidade • Present some potential applications related to BIM and other Digital AEC Technologies • Snapshot of many different initiatives on Smart Cities in Brazil • A very personal view of topics of smart and sustainable cities according to the recent but intense experience of LCTU/Conecticidade

• A much more personal view on some opportunities to apply new approaches for research and professional applications on the topic of Digital Technologies for a Smart City • A small contribution for a Research Agenda?

Some Brazilian challenges Size

Brazil x Europe

Uneven Distribution

Urbanization

Inequality

Among and within Regions

Dealing with Digital Technology at the City scale • GIS+ Expanded Geotechnologies • BIM • Integration • Coordination • Collaboration

• BIM in Infrastructure • CIM (City Information Modelling)

• Smart City Approach is dependent of a particular representation of the city and its elements and GIS + BIM are the basic foundation of that 4

Elements of concern • CIM as City Representation (GIS+ / BIM / Digital Twins and beyond) • Planning, Modeling, Simulating, Emerging Structures • Environmental Challenges • • • •

Natural Environment Built Environment Climate Change Energy – Material Efficiency

• How many adjectives for a CITY? • Digital - Smart – Sustainable – Efficient – Innovative – Democratic – Inclusive – Resilient – Happy

• Some concrete, pratical and solution oriented (broad) approach 5

Open Data in São Paulo – different potential applications GeoSampa is not only a Digital Map provided by the Municipality of São Paulo (Brazil) , but it is actually a Digital Portal for Open Data of São Paulo colleted, organized and making available for researchers, professionals, planners and citizens

Looking at Open Data and applying for Smarter City Approach • • • •

Institutional arrangements of data collecting and availability Transparency and different opportunities for understanding a big city Types of data and their use Capabilities for organizing data for planning and management different services in city • Role do GIS • Role of BIM

• What is making available? • 2D information • 3D like information • LiDAR generating set for 3D model and Digital Terrain Model (DTM) of the City

3D Data (LiDAR) available for São Paulo

•

3D cartography of the entire city of São Paulo is available on GeoSampa. With the new platform update, citizens will be able to visualize buildings, trees and works of art in a threedimensional way on the digital map of the city.

• Data were obtained through an aerial survey carried out between May and July 2017 using laser technology. LiDAR (Light Detection and Ranging). • The technology does not just present a satellite image or area photograph of the territory, but a high-resolution geometric representation of the city.

Areas of interest of Conecticidade/LCTU research group and the 3D Modeling of the City of São Paulo (CIM) possible applications • • • • •

Public Lighting Systems and Services Security Cameras (CCTV) Systems Microclimate Simulations Smart Mobility and Transportation Infrastructure, Assets and Utilities Systems Management and Governance • Risk Management and Resilience • Building and Infrastructure Management, Operation & Maintenance Process and Simulation 9

Public Lighting Systems and Services • Integrated GIS + BIM • Planning, Design, Implementation and O&M Management • City- and District-wide modeling and simulation on quality of service, safety and efficiency for users • Integration of different utilities infraestructures and networks • Trends in innovation and new technologies of produts and processes

Security Cameras (CCTV) – Secutrity Services • Integrated GIS + BIM • Simulation on position points of view and coverage • Different equipments and software tools • Prevention and law enforcement

• Protection of privacy and community safety • Integration with other systems and networks

Infrastructure, Assets and Utilities Systems Management and Governance • Dealing with urban infrastructure networks (streets, utilities and open areas) • “Unknown underground” mapping and existing underground utilities networks • Interference of systems: costs and risks • New types of solutions and business arrangements (Management and Governance) • Using BIM for planning, designing, simulation and “as built” repository

Microclimate and Urban Forms • Research on microclimate and urban forms – simulation and assessment for design guidelines and effects on energy and environmental conditions • Gabriel Bonansea de Alencar Novaes (MSc) • Leonardo Marques Monteiro (PhD)

• Variability of shapes and heights of building as factor for improving the city´s thermal and energy performance (Proposed PhD Thesis) • Impacts of city morphology on the microclimatic conditions of consolidated urban areas in São Paulo during hot days (MSc Dissertation) • NOVAES, G. B. A. Impactos da Morfologia da Cidade nas Condições Microclimáticas de Áreas Urbanas Consolidads de São Paulo em Dias Quentes . São Paulo: Dissertação de Mestrado apresentada à Faculdade de Arquitetura e Urbanismo da Universidade de São Paulo (FAU USP), 2020.

Initial research: Five different areas in São Paulo (Brazil) This research carried out an evaluation of the potential impacts that different morphological compositions of consolidated urban areas can cause on the local microclimate conditions during hot days perceived on the pedestrian scale, based on simulations of the thermal conditions of open urban spaces exemplifying neighborhoods in the city of São Paulo.

Mesuring actual conditions and preparing a model Using the ENVI-met Software on 3D model, calibrated from empirical measurements of microclimate variables collected in an existing city environment

Campbell Scientific Station and HOBOs

3D Models 15

Using 3D Modeling: applying analytical and simulation tools The results of the evaluations of five different models, comparing their different occupation aspects, allowed verifying that the morphological conditions are capable of contributing to the alteration of the main thermal variables of the open urban space and pedestrian thermal comfort index.

In the studied models, it was found that, the greater density and verticalization, the milder the thermal conditions of open urban spaces during the daytime, due to the shading caused by the buildings, and the air temperature values at night are higher, due to the higher emission of long-wave radiation by the urban canyon at night

Smart Urban Mobility – Beyond the 2D simulation models • Multi dimension simulation models • Integrating Urban Infrastructures and Building and Systems Assets • Assessing solutions with large scale simulation models of multimodal mobility • Micromovement behavior of citzens • “Consumption” of Urban Structures Souce: Autodesk

• Occupation, Usage and Urban Forms • Dynamic os built environment • Smart city for smart population 17

Some Final (Maybe...Intermediary) Remarks • Development of professional competence and capability on: • • • •

Spatial Representation, Analysis and Thinking Approach Complex Systems BIM/CIM as a “language and common tool” for AEC and Urban Professionals Integrating Planning, Designing Implementation and Management Activities

• What do we mean abour SMART cities? • Digital City is very different of a Smart City • Smart City is also different of an Intelligent City

• Both in Italian and Portuguese (Latin languages) we have that lost in translation • Smart city (in Portuguese) seria “uma cidade esperta para os seus cidadãos espertos” • Smart city (in Italian) sarebbe “una città astuta per la sua gente astuta” 18
