Case Study: City Inn

A Building Energy Management solution to reduce energy waste.

City Inn, located in the heart of Westminster, is taking steps to improve on its already efficient energy systems by cutting energy consumption, improving efficiency and minimising utility bills by using t-mac Technologies.

The hotel has installed the t-mac building energy management systems to monitor and meter the building’s energy use.

t-mac is able to identify the key energy consuming areas of the hotel by remotely logging live metering data from the building The City Inn team is then able to identify areas of high energy waste or excess energy consumption by logging on to a dedicated t-mac webpage. This interactivity allows the hotel to remotely manage its heating and lighting equipment and undertake action to reduce energy use and cost.

Up to 11 activity areas have been identified for City Inn, which are being sub-metered through t-mac. Including the plant room; external lighting; conference room; private dining; kitchen and staff room lighting as well as the first and sixth floors of the hotels.

Sub-metering via t-mac enables City Inn to:

  • Determine which parts of the hotel use the most energy when activity is at its highest.
  • Assess where there are areas for energy saving opportunities.
  • Undertake evasive action to improve the excess energy consumption.

David Orr, Chief Executive and Co-Founder of City Inn said: “Reducing our impact on the environment is instilled within our corporate culture and we are making sure we only use utilities and equipment when they are needed and we are committed to reducing waste.

“With a hotel which is operational 24 hours a day, seven days a week, minute by minute monitoring of energy use is almost impossible to manage, but t-mac offers the ideal solution. t-mac can monitor multiple and specifics areas of the hotel and by applying day-night profiles for each individual area we can set energy consumption benchmarks to enable us to determine problem areas. Another major benefit is that we can also uncover opportunities to improve the overall efficiency of the hotel which helps us to reduce consumption, minimise our environmental impact and also save money.”

Following the first few weeks of installation, the team has already identified areas for improved energy efficiency by tweaking consumption patterns for most of the 11 activity areas being metered and monitored. Plans are currently in place to implement change of the hotel’s BMS and t-mac will be used to identify potential cost and carbon savings.
