The Birmingham Gateway Project: Feasibility and implementation of CHP Azhar Quaiyoom

2 Birmingham City Centre and New Street Station – current station

Atrium Extension to footbridge Iconic cladding 4x concourse Opening of walkways Improved connections 3 new entrances 21 st century feel Enhanced platforms Enhanced retail Support 150% growth Airport style lounges Improved platform connectivity The Proposed Station - £600M refurbishment - 5 year construction programme

Date Moor Street Link

Date North West Entrance

6 View through Atrium to allow natural daylight

7 Drivers and approach to Sustainability Environment / NR Policy NR & Mace sustainability Policy New builds – BREEAM ‘Excellent,’ refurb ‘Very Good’ – GATEWAY PROJECT Pollution and climate change Economic Payback / IRR / NPV Whole Life costs Drive for efficiency Rising cost of fuel Cost/benefit Social responsibility Community engagement Design with future in mind Carbon footprint reduction Social inclusion Legislation Building Regulations Planning Policies EU Buildings Directives CRC / RHI Design/Engineering

8 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

9 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
