Architect and public health researcher

I started doing architecture in 2002 and for health environments since 2007. Early in my career, I visited many hospitals in my home country Venezuela where technical-medical planning was unquestionable and patient and staff-centered designs completely absent. To convince facility managers about doing architecture for health required proof of concept and show ROI. It was necessary to learn public health research and methods to produce evidence, and I did. Training at the Berlin School of Public Health at Charité was a big step, it helped me propose interventions to improve health outcomes at the urban scale.

At TU-Berlin, I currently contribute to capacity-building in Urban Health at the Urban Management Program and the Department of Design and Building Sciences van Rijs.

I also founded the Building Health Lab in 2018, a Think & do Tank with the mission of applying health strategies to reach sustainable urban developments. The Lab bridges academia with practice with a framework called UrbanCare, a pedestrian health approach with transdisciplinary problem-solving techniques.
Through the UrbanCare project, our team helps other researchers develop case studies across Europe to support urban ecosystem regeneration and human health at the neighborhood level. Globally, we also collaborate with climate and health advocacy groups such as the Architects Declare and the Global Health Hub.

Born in Venezuela, Alvaro spent most of his childhood in the U.S.A. to later return and achieve an architecture diploma in Caracas. In Spain, he completed construction management and then moved to Berlin, Germany. His vision to combine health and architecture got him accepted to study at the Charité Medical University of Berlin, the first architect to achieve a Public Health master at this institution.
In academia since 2011, Alvaro has been an Evidence-based Design Researcher at the Technische Universität Berlin, where he has conducted numerous pedestrian evaluation projects in various countries. At the TU-Berlin Urban Management Program, he teaches Urban Walkability, and at the Architecture faculty, he conducts research on healthcare delivery environments in collaboration with WHO Téchne.
In practice, Alvaro is the founder and manager of BHL Building Health Lab, a Think & Do Tank that creates health strategies to integrate sustainable development goals in urban planning and architectural design.
At BHL, he conceptualized and developed UrbanCare, a methodology to assist city planners in structuring cases for urban health in different climate zones such as the Oceanic in Gothenburg, Continental in Berlin, Intermediterranean in Florence, and the Mediterranean climate in Nicosia.

Alvaro also acts as commissioning editor for the Cities & Health Journal, collaborates with the German Architects Declare for Climate and Biodiversity, and is a member of the German Alliance for Global Health and the pedestrian advocacy group “Fuß e.V.” in Berlin.

Evidence-based design in healthcare settings

Healing architecture concept and evidence based design research

This chapter develops on the premise that Healing Architecture works but cannot explain its curing capacities without support of an Evidence-based Design (E-bD) approach. A field redefined in this essay as the process that ensures architecture develops to enhance human health.

City Development for health

Principles for Assessing population health; Walkability evaluation; Streetscape Design

City Development is a teaching research project that started in the Winter Semester of 2013 with a course titled Building Health. 

Understanding Walkability

An urban form and street pattern comparison


This descriptive study provides information indicative of the interaction between physical features of neighbourhood environments with health behaviours such as walking and biking which consequently affect disease rates related to lifestyle.

Urban Medical Neighborhoods

Considerations on building neighborhood health ecosystems

Aiming transformational change in healthcare, this study elaborates on how sustainable health systems be acheived when built on the strongest pillar of any country’s economy: the building sector.
