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

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
