EIS Headquarters, Moray Place, Edinburgh
The Brief
The Educational Institute of Scotland (EIS) wanted to implement a sustainable energy solution for their historic, 250-year-old headquarters in Edinburgh. Their goals included cutting energy costs, reducing their environmental footprint, and aligning with their commitment to sustainability. However, the project presented several challenges. The building’s limited roof space and shading from heritage architectural features posed significant obstacles to solar panel installation. Additionally, it was critical to preserve the architectural integrity of the listed building and ensure compliance with strict conservation regulations. EIS required a solution that was both innovative and sensitive to these unique constraints.
Your Approach
Ceiba Renewables approached the project with a customised solar solution designed to address the specific challenges of the EIS headquarters. After detailed site assessments and planning, 24 high-performance SunPower Maxeon 425W AC panels were strategically installed across four distinct roof areas. To maximise energy output despite partial shading, Enphase microinverters were integrated into the system, ensuring optimised performance under challenging conditions.
Beyond the technical aspects, Ceiba Renewables worked closely with conservation authorities to ensure full compliance with preservation regulations, maintaining the historic character of the 250-year-old building. The team meticulously planned and executed the installation, balancing cutting-edge technology with the delicate demands of heritage preservation. The process included thorough risk assessments, precise equipment placement, and careful coordination to avoid any disruption to the building’s operations.


The Result
Ceiba Renewables approached the project with a customised solar solution designed to address the specific challenges of the EIS headquarters.

The solar energy system at EIS headquarters has delivered significant and tangible benefits:
- Annual Energy Production: Generates up to 14,000 kWh of clean energy each year.
- Cost Savings: Reduces electricity expenses by approximately £4,500 annually.
- Carbon Footprint Reduction: Lowers CO₂ emissions by over 3,000 kg every year.
- Real-Time Monitoring: Provides live performance tracking and data collection for sustainability reporting.
This level of transparency enables the organisation to showcase its commitment to environmental stewardship while maintaining operational efficiency. By combining cost savings, reduced emissions, and an optimised design, the project exemplifies how renewable energy can be seamlessly integrated into historic buildings, setting a benchmark for sustainable innovation.
The Ceiba Renewables team delivered exactly what we needed—an energy solution that reduced our costs while fitting perfectly with our historic building. The process was smooth from start to finish, and the team’s attention to detail was exceptional.
