Background

The Runneymede Hotel, located in Egham, is a luxury hotel offering a range of services and amenities to its guests. To maintain its high standards, the hotel sought to optimise its energy efficiency, enhance guest comfort, and streamline the management of its facilities. 

This necessitated the integration of a Building Management System (BMS) that could centrally control and monitor the hotel's various mechanical and electrical systems.

Daniel Harvey Consulting Limited was employed by Design Haus Services Limited www.designhss.com to review energy management and deliver BMS cost analysis, systems design,  commissioning and project management.

Objective

The primary objective was to integrate the BMS to effectively manage the following systems:

Air Handling Units (AHUs)

Heating and Cooling Systems

Room Temperature Regulation

Bar(s) Temperature Regulation

Challenges

Legacy Systems: The hotel had several legacy systems that needed to be integrated into a new, unified BMS.  Compatibility between different systems and equipment was a major concern.

Energy Efficiency: The hotel aimed to reduce energy consumption while maintaining or improving the comfort levels in guest rooms and common areas.

Real-time Monitoring and Control: The hotel required a system that could provide real-time data and control capabilities to adjust the settings based on occupancy and external conditions.

Minimising Disruptions: Integration work needed to be carried out with minimal disruption to hotel operations, ensuring guest comfort and business continuity.

Solution

BMS Integration / BMS Controls Panels:

A modern, BMS was chosen that could interface with the existing mechanical and electrical systems, including AHUs, heating, cooling, and room temperature regulation systems.

The BMS was equipped with communication protocols (e.g., BACnet, Modbus) to ensure seamless integration with different subsystems.

MCP01 panel with Trend IQ4E and CP01 panel with Trend IQ4E system, full design and build with  BACnet to AE200 compatibility and BACnet/Modbus compatibility for integration with the high-level interface of the new Air handling units.

The IQ4E controller uses Ethernet and TCP/IP networking technologies with embedded XML and is fully compatible with other Trend IQ controllers. The IQ4E supports BACnet over IP as standard.  

Centralised Control: 

The BMS provided centralised control that allowed hotel management and facility operators to monitor and adjust settings for all integrated systems. The system enabled real-time adjustments to the HVAC systems based on occupancy data, weather conditions, and time of day.

Energy Management: 

The BMS was configured to optimise energy usage by automatically adjusting heating, cooling, and ventilation based on occupancy and other factors. Energy consumption data is continuously monitored, and the BMS provides reports and analytical interventions to help identify areas for further energy savings.

Room Temperature Regulation: 

Individual room controls  were linked to the BMS, allowing for personalised settings for guest while ensuring energy efficiency when rooms were unoccupied.

The system could pre-cool or pre-heat rooms before check-in, enhancing guest comfort.

Minimal Disruption: 

The installation and integration process was carefully planned to avoid disruptions to hotel operations. Work was scheduled during off-peak hours and in phases to ensure that guests were not inconvenienced.

Results

Improved Energy Efficiency: 

The hotel saw a significant reduction in energy consumption, particularly in heating and cooling  costs. The BMS's optimisation capabilities led to more efficient operation of the HVAC systems.

Enhanced Guest Comfort: 

Guests experienced improved room temperature regulation, with the ability to control their environment according to their preferences. Common areas of the hotel also maintained a consistent and comfortable climate, improving the overall guest experience.

Operational Efficiency: 

Facility management benefited from real-time monitoring and control, reducing the need for manual adjustments and interventions. The BMS provided actionable insights through data analytics, allowing for proactive maintenance and further optimisation of building operations.

Sustainability Goals: 

The integration of the BMS supported the hotel’s sustainability goals by reducing its carbon footprint and enhancing overall energy management.

Conclusion

The integration of the BMS at the Runneymede Hotel in Egham successfully addressed the hotel's needs for energy efficiency, guest comfort, and operational control. 

The project highlights the importance of a well-designed and integrated BMS in modern hospitality settings, demonstrating significant benefits in both operational performance and environmental impact.
