The Challenge

The Challenge

BOTA 75 is a shared office building that hosts multiple charitable and nonprofit organizations. The building relied on a gas-based heating system and offered significant opportunities for operational improvements and renewable energy integration. The challenge was to reduce emissions while accommodating the needs of multiple tenants and maintaining a functional workplace environment.

Why this building

BOTA 75 demonstrates how shared office buildings can be transformed into low-carbon workplaces. Because the building serves multiple nonprofit organizations under one roof, the project creates impact beyond a single tenant and provides a replicable model for similar multi-tenant office buildings across Europe.

Frictions encountered

  • Coordinating decarbonization measures across multiple occupants.

  • Replacing existing fossil-fuel-based heating infrastructure.

  • Balancing operational improvements with daily building use.

  • Integrating renewable energy systems into an existing building.

  • Aligning technical solutions with the needs of diverse tenant organizations.

Measures planned/ implemented

  • Operational energy optimization.

  • Replacement of gas heating with a renewable alternative.

  • Ventilation improvements.

  • Rooftop photovoltaic installation.

  • Building controls optimization.

  • Energy monitoring and performance management.

Co-benefits

The project improves comfort and energy performance in student housing while supporting UConn's pathway toward a zero-emissions campus. The resulting retrofit strategies can be replicated across the university, amplifying climate impact well beyond the initial buildings.
