Challenges & Constraints of Refurbishment• Limited insulation with existing façade
retained
• Accessibility for passengers increases open areas to outside – issue for thermal comfort
• 28 new escalators, 31 new lifts – increase of energy demand – from 9GWhr to 14 GWhr/Year
• Open track area below concourse with Overhead Lines – limited areas to insulate
• Limited space for renewables ideas (i.e. Biomass space and sub-surface regs) and many third party interfaces

Low / Zero Carbon Technology Study• Consultant Atkins carry out a study to establish viability
of low carbon technology (Sep’t 09’)• Solar Photovoltaic Solar Photovoltaic • CHP – (reduce CO2 & costs)• Ground Source Heat Pumps• Solar thermal• Biomass Boilers

Challenges for CHP• Complicated contract for ESCO – Works and
maintenance elements• Unfamiliar contract and risk to Network Rail• Integrate design & operation into a complex Gateway
project• High electrical load / low heat demand• Asset Protection for station operations
• Long terms contracts – 25 years typical• Asset owners and RAMS acceptance is critical• Third party access rights and protocol required

Possible Routes – use of sub platform tunnel Networks
![Page 12: The Birmingham Gateway Project: Feasibility and implementation of CHP Azhar Quaiyoom](https://reader035.fdocuments.in/reader035/viewer/2022062520/56815858550346895dc5b3d3/html5/thumbnails/12.jpg)
Benefits for CHP at New Street• Significant reduction in Carbon emissions >3,000Ton/yr
& supports BCC carbon reduction targets
• Provide model case for role out to other managed stations
• Reduction in energy bills
• Use of strategic tunnel network avoiding disruptive infrastructure works around the city
• Potential for significant expansion of the system with heat provision to adjacent buildings
• Provision for South side to be ‘CHP ready’
• CRC benefits to Network Rail
