The Birmingham Gateway Project: Feasibility and implementation of CHP Azhar Quaiyoom
Birmingham City Centre and New Street Station – current station
Enhanced platforms Opening of walkways 21st century feel Improved platform connectivity 4x concourse Atrium Enhanced retail Iconic cladding Improved connections Airport style lounges 3 new entrances Extension to footbridge Support 150% growth The Proposed Station - £600M refurbishment - 5 year construction programme
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 • Legislation • Building Regulations • Planning Policies • EU Buildings Directives • CRC / RHI • 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 Design/Engineering 7
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 • 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
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
