Métodos de avaliação de projetos de Habitação Social: apoio à tomada de decisão participativa e baseada em evidências

Autoria SCIMAGO INSTITUTIONS RANKINGS

Resumo

Infraestrutura inadequada e espaços públicos de baixa qualidade em Empreendimentos de Habitação de Interesse Social (EHIS) afetam negativamente o bem-estar dos moradores, agravado pela falta de participação que prioriza a redução de custos em detrimento das necessidades do usuário. O design baseado em evidências, comum na área da saúde, pode melhorar a qualidade do SHP integrando evidências em processos de design, mas seu uso é limitado. Este artigo apresenta um estudo sobre métodos de avaliação, destacando métodos recomendados para processos de projeto participativo e tomada de decisão envolvendo partes interessadas multidisciplinares. Uma oficina com profissionais e acadêmicos explorou os processos de projeto e aprovação de EHIS, revelou desafios como prioridades orientadas pelo mercado, regulamentações pouco claras e colaboração insuficiente, destacando a necessidade de abordagens mais transparentes e baseadas em evidências. Uma revisão de literatura identificou ferramentas para alinhar decisões de design com as necessidades do usuário, mas questões como complexidade, falta de conhecimento, custos e barreiras culturais dificultam sua implementação. Esta pesquisa destaca a necessidade de refinar e adaptar essas ferramentas ao contexto de EHIS, promovendo integração de evidências e colaboração em projetos habitacionais.

TOOL	REQUIREMENTS FOR USE	INTERFACE AND PRESENTATION OF RESULTS	DESIGN PROCESS	POSITIVE POINTS	LIMITATIONS
AEDET Design Evaluation Toolkit	User-friendly open tool	Paper or Excel spreadsheet with automated scoring. Intuitive interface. Results in graph form.	It can aid in the design process by improving stakeholder communication and evaluating existing buildings for improvements.	It is an easy-to-use tool with an intuitive interface, evidence-based criterion descriptions, a supported evidence database, shared scoring for multiple users, and an overall score for trade-offs.	No quantitative resources or parameters for comparison
DQI Design Quality Indicators	A DQI-accredited facilitator is required.	The results are presented in radar and doughnut graphs for easy comparison, domain balance, and facilitator feedback.	It can be used throughout the construction life cycle	The DQIfFH replaced the AEDET tool in 2010. It has parameters for scoring, more objective criteria, and criteria relating to the surroundings and buildings.	The results are not easy to visualise or evaluate. The system could have a more automated and user-friendly interface.
HQI Housing Quality Index	No facilitator is needed.	The evaluation is available in MS Excel and paper versions. It displays scores for each criterion but does not allow comparison or visualisation through graphs.	It can be used throughout the construction life cycle	It is an adaptation of the DQI for housing projects, providing guidelines for unit development and objective scoring parameters.	The focus is more on the housing unit. The results are not easily visualised or evaluated. The system could be more automated and user-friendly.
SPeAR Sustainable Project Appraisal Routine	ARUP recommends a facilitator for the evaluation phases, but it is not mandatory.	There is a web version and a desktop version. The results are presented in a radar graph with the score from a traffic light system.	This tool can be used at various stages: to assess and pinpoint gaps, compare pros and cons, and for post-construction and post-occupancy evaluation.	It is an interactive, easy-to-use system that can also be adapted. It uses indicators from other guides and standards as a model.	It could contain a general score to give an overview of the fulfilment of the criteria and the enterprise’s score to facilitate trade-offs.
VALiD Value in Design	Needs an external facilitator	The evaluation interface includes dashboards with criteria, target values, a radar graph, and user and customer questionnaires.	It has a similar structure to CABE and RIBA. Its three stages can be applied throughout the entire design process.	It involves meeting with stakeholders to understand the project’s goals, objectives, and values and obtaining individual assessments from each stakeholder.	There are no pre-defined criteria or parameters for evaluation.
Building for Life	Ventures are not required to hire an external consultant for evaluation, but they can do so.	The results are shown in a radar graph with the score from a traffic light system.	It can be applied at all stages, from initial to discussion.	It includes use cases, questions, principles, and guidelines for application.	It does not have quantitative parameters that allow the objective measurement of locations.
Place Standard Tool	No facilitator is needed; anyone can fill in the forms.	Intuitive and easy-to-use interface available in both paper and online versions. Results are displayed as feedback on evaluation sheets, forming a final radar chart with stakeholders’ scores.	It can be used in the initial phases, during the project process as an action plan to aid community decision-making, and as a tool for monitoring and continuously improving the site.	It has a guide for the designer and the community, as well as materials on how to organise the workshops, and it has a database that supports the evidence; more than one respondent can access it, and the score is given jointly; it has an overall score that helps with trade-offs	It does not have quantitative parameters that allow the objective measurement of locations
Place Value & the Ladder of Place Quality	The British government conducted the audit, but the materials for the evaluation and evidence are available.	The results include scores by category, criterion, and overall score using a value scale, information about the socio-economic profile, and general location observations.	The tool and its criteria can aid project decision-making and evaluate existing and constructed sites.	The assessment is based on case studies and evidence, with a public evidence bank for reference. It considers aspects that add value to the location, provides examples for evaluation, and includes socioeconomic and geographical characteristics of the cases.	The available materials do not fully explain the evaluation process or provide a detailed document outlining the evaluators’ assessment parameters and specific actions.

Problems	Solutions	Design tools
Lack of Consideration of Evidence and Users’ Needs	Use of a tool to mediate discussion, capture, and record user requirements directly through a participatory process or indirectly through evidence from previous research or cadastral analysis.	VALiD - Value in Design, Place Standard Tool, Place Value & the Ladder of Place Quality, Building for Life
Market-Driven Decision-Making and Low Profitability	Consideration of other important stakeholders and decision-making supported by consistent information.	AEDET – Design Evaluation Toolkit, Place Standard Tool, VALiD - Value in Design, SPeAR – Sustainable Project Appraisal Routine, Place Value & the Ladder of Place Quality, BREEAM Communities
Stakeholder Complexity and Collaboration Issues	Use of collaboration and communication tools.	AEDET – Design Evaluation Toolkit, SPeAR – Sustainable Project Appraisal Routine, DQI – Design Quality Indicators, VALiD - Value in Design, BREEAM Communities
Lack of Best Practices and Quality Criteria	Establishment of guidelines and regulations to ensure higher quality.	DQI – Design Quality Indicators, HQI – Housing Quality Index, Place Value & the Ladder of Place Quality, Living Community Challenge, One Planet Communities, Building for Life, Place Standard Tool, SPeAR - Sustainable Project Appraisal Routine, BREEAM Communities
It is an informal, Evidence-lacking, and Non-systematic Design Process.	Use tools that indicate necessary information, the interrelation between requirements, and the impacts of decisions.	AEDET – Design Evaluation Toolkit, Place Standard Tool, Place Value & the Ladder of Place Quality, BREEAM Communities
Need for Culture Change and Tool Implementation	Staff training and the use of tools supported by workshops are also needed.	Place Value & the Ladder of Place Quality, VALiD - Value in Design, Place Standard Tool, BREEAM Communities
