The Compass Project in Aberdeen is an inspiring initiative led by the Camphill Wellbeing Trust, transforming the former Waldorf School into a vibrant centre dedicated to healthy, sustainable living.

The site now serves as a community hub, offering workshops, volunteer sessions, product pop-ups, and educational events, all focused on practical sustainability. To support this mission, the Trust required a renewable, efficient, and future-ready heating solution that could meet the demands of the site’s growing activities while embodying the environmental values at its heart.

The Requirements

Transforming the historic school into a modern, low-carbon facility came with unique requirements:

• Deliver reliable and efficient heating and hot water across a range of community spaces.
• Ensure flexibility and scalability for varying heating demands.
• Operate effectively in the Scottish climate, maintaining performance even in low temperatures.

The Solution

To achieve these goals, the Compass Project installed a cascade Air Source Heat Pump system centred around:
6 × CTC EcoAir 622 Air Source Heat Pumps Controlled by the intelligent CTC EcoLogic L Controller.
