For this flagship project, our team delivered a fully bespoke HVAC and heat recovery ventilation solution to a large-format clothing store in a busy Weymouth shopping centre. The system was meticulously designed to maintain optimal climate control and impressively reduce energy use, supporting both tenant comfort and operational objectives. By leveraging the highly efficient Mitsubishi Heavy Industries VRF (Variable Refrigerant Flow) units, complemented by intelligent zonal controllers and advanced heat exchangers, we provided seamless integration of heating, cooling, and energy recovery—all in one robust installation. This project exemplifies how forward-thinking engineering and premium components drive lasting value for retail environments.
The Challenge
The client required not just comfort, but consistency—a major challenge for such a high footfall space. Maintaining precise temperatures across over 3000 ft of retail floor meant overcoming variable weather, occupancy fluctuations, and large glass shopfronts. Efficiency was equally vital: the system needed to cut utility costs and carbon footprint significantly. Our solution demanded carefully calibrated air distribution, real-time adaptive control, and a commitment to sustainability from the outset.
The Solution
As part of an expanding portfolio of large commercial projects, our approach focused on advanced system capabilities and proven results. The installation (June–August 2025) included:
- High-Efficiency VRF from Mitsubishi Heavy Industries: State-of-the-art City Multi Series offers superior energy performance, intelligent load balancing, and variable speed inverter compressors. This setup provides considerable energy savings and reliable comfort compared to conventional systems.
- Centralised Touchscreen Control: User-friendly Mitsubishi Heavy Industries Diamond Controllers enable instant adjustments and scheduling for multiple temperature zones, optimising comfort in real time.
- Heat Recovery Ventilation (HRV): Using Lossnay heat exchangers, exhaust air pre-conditions fresh supply air, reducing the overall heating and cooling demand for lower operating costs.
- Demand-Controlled Ventilation & Sensors: CO₂ and occupancy sensors adjust airflow and temperature automatically, enhancing indoor air quality, maximising comfort, and increasing system lifespan.
- Quality Electrical Integration: All power, distribution, and control wiring undertaken by our certified team, following the latest IET Wiring Regulations for full compliance and safety.
- Comprehensive Lifecycle Support: The project included a five-year warranty, regular scheduled maintenance, 24/7 service support, and extensive training for store managers and building administrators to maximise system performance.
The Results
Within weeks of commissioning, temperature measurements showed a consistent 19°C across all retail zones—even during peak summer crowds. Initial monitoring indicates a significant reduction in annual HVAC energy consumption compared to typical retail setups, supporting both lower energy bills and a reduced carbon footprint. Customer feedback has been overwhelmingly positive, citing an inviting environment that encourages longer dwell times. The system’s heat recovery feature now continuously reuses otherwise wasted energy, transforming it into useful heating or cooling and optimising operational efficiency.
This project is a showcase of advanced mechanical engineering, intelligent application of Mitsubishi Heavy Industries technology, and commitment to sustainability—all tailored for a dynamic retail environment.
