We provide design, energy modeling, and simulation services to our clients, framing our recommendations within existing legislation and future climate data. Nearly Zero-Energy Buildings (nZEB) and Energy-Positive are at the core of our services. Our holistic approach is based on Life Cycle Assessment, balancing passive and active solutions, building performance, and environmental impact of materials. Human comfort (thermal and visual) guides our energy-efficient recommendations.
The Portuguese building stock is a priority for the European Commission within the Renovation Wave initiative. Based in Porto, Portugal, at Dosta Tec we create solutions at the forefront of the transformation.
Mateo Barbero
co-founder
Industrial Engineer, specialised in Sustainable Energy Systems through the MIT Portugal program at the University of Porto. BREEAM Associate.
As a Researcher at INESC TEC’s Centre for Power and Energy Systems (CPES), he developed research projects in the area of building energy services, energy efficiency, and sustainable cities, in both the private and public sectors.
Graduated from the Buenos Aires Institute of Technology (ITBA, Argentina), he first worked in software development and later in consultancy for the energy sector. He has developed and held training courses and practical workshops on decision support, stochastic analysis, and energy modelling, with experience working on-site in Latin America, China, and Europe.
Adrian Krężlik
co-founder
Architect graduated from the Technical University of Łódź (Poland), worked for Zaha Hadid Architects in London (2009-2011), and later for Fernando Romero (2011-2012) and Rojkind Arquitectos (2013-2014) in Mexico City. In Poland, he founded the Contemporary Architecture Foundation which has organized more than seventy events dedicated to parametric design.
He is interested in science-based architectural
design, especially based on building performance, and its impact on the environment. He lectured in Barcelona, Cairo, Copenhagen, Helsinki and Warsaw, to list some. He was a Visiting Assistant Professor at Weißensee Kunsthochschule in Berlin. He is an architecture curator for the Polish Pavilion for the EXPO 2020.
Adrian has started PhD research at FAUP in 2019 and joined CEAU in 2020, in 2021 he joined MIT Portugal PhD Program.
Jordana Moreira
Carbon and Energy Analyst
Born in Brazil, holds a Master’s Degree in Architecture from Lusófona University of Porto (ULP). Her thesis, titled “Parametric Design as a Methodology Supporting Architectural Practice: The Example of Optimizing Thermal Comfort in Buildings,” centered on optimising natural lighting within building interiors through the use of parametric tools and genetic algorithms applied to facade design.
Jordana is an BREEAM AP.
Evandro Barros
Carbon and LCA Analyst
Born in Luanda, Angola. Recently, graduated from a Master´s Degree in Architecture at Lusófona University of Porto (ULP) with a dissertation entitled A Reflection on structure as a Form of Architecture: Los Manantiales – Félix Candela. This academic research introduces structural efficiency as a form-steering method to achieve organic and more sustainable architectural designs. Furthermore, he has an academic project published by Politécnico di Milano on high-way constructions.
His interests involve design and structural development, materials, and environmentally based solutions. As such, he is currently an intern at Dosta Tec to further develop his understanding of sustainable concepts, the impact of design decisions and different ways to address sustainability within the construction sector.
Julia Karnaś
Energy and Comfort Analyst
Julia graduated from the School of Form in Warsaw with a degree in Industrial Design. She defended her thesis entitled “Neighbourhood Climate Shelter. Research of thermal discomfort in the era of the climate regime.”. In 2022 she spent a semester at the University of the Arts in Reykjavík, where she developed an interest in material radicalisation in design and architecture. Her work links climate change and social issues.
In 2022, she organised the OSSA workshop in Gdynia. Her work participated in the exhibitions at Gdynia Design Days 2021 and Lódz Design Days 2021 in Poland. After completing her bachelor’s degree, she started an internship at Dosta Tec, where she continued her research on embodied carbon in the construction sector.
