For the new building of the State Congress of Puebla, an iconic and forceful architecture was conceptualized within the urban context, making the most of its location in one of the most historically important points in the state. The 23,846 sq m project was built from 2023 to 2024, it is located on Cerro Acueyametepec in the Fuerte de Loreto park, next to the Ignacio Zaragoza Olympic stadium.

The selected property is based at the beginning of the volcanic stone bed of the hill. In conjunction with the National Institute of Anthropology and History (INAH), a strategy was defined to integrate the building into the natural context providing continuity to the Cerro de los Fuertes with a green slope with the intention of incorporating the natural landscape of the historical context into the project. The building was partially buried in the hill and has green roofs that integrate with the natural environment, covering a percentage of 59.92%. This helps reduce the heat island, the volumetric impact of the building in the context and the maintenance consumption for air conditioning of the facility.

The space generated between the two blocks creates a central atrium that links all the activities within the premises. The configuration and scale of this space is governed by free height and natural lighting, resulting in a dynamic space for integration and coexistence of users. It presents as an innovation factor the creation of an internal street covered with natural light, designed for meetings and avoiding a sedentary lifestyle, where murals and art are displayed in public areas. The interior street at the same time creates a connecting space that filters the different users in an organic and safe way. This space breaks with the typical corporate environment of repetitive and isolated spaces with an urban gesture where the connection between the interior and exterior of the building is direct.

Sustainability is the central axis of this project, resulting in a functional, sustainable and avant-garde complex. The requirement of 40% permeable area and 60% free area is met, prioritizing the natural environment over the building. The envelope of the volumes is made up of a series of mullions that adapt to t
he climatic conditions of the area.

Regarding water use, a saving of 45.4% was achieved for all services. In addition, there is a wastewater treatment plant that processes 100% of the gray and black water, reusing it in bathroom furniture and maintenance of garden areas, 100% of the rainwater captured on the roofs is also reused for the same purposes. Landscaping includes native and endemic plants that do not require potable water for irrigation.

The design seeks to reduce costs through a model designed for energy efficiency, mitigating the heat island effect and recovering green spaces. The envelope, with sunshades and terraces, reduces solar incidence, while the green roof recovers green areas providing good insulation.
