    • Setting new standards in communication
    • Sean Lockie POE results Cheshire Oaks
    • Overview of POE Tasks • 1 year’s worth performance monitoring • Assess building envelope • Benchmark against other M&S stores • Assess the sustainable features • Survey staff & customers • Review biodiversity • Disseminate the good practice lessons
    • Questions the POE aims to answer • Which features work, and which do not? • Is the extra effort worth the investment? • Are operational costs reduced? • Do the store’s features attract more customers & generate more sales? • What are the key lessons for future developments?
    • Performance Targets for the Store
    • Building Performance – Electricity Trade lighting 16% Stock lighting 13% Other lighting 11% External Lighting 2%Refrigeration 21% HVAC 8% Mechanical handling 2% Catering 14% IT / Communications 1% General power 2% Miscellaneous 10% 42% elect load = lighting HVAC only accounts for 8% of site demand - half as much as typically seen in retail

    • Water Use – Daily Profile 0 1 2 3 4 5 6 7 6 Nov to 21 Nov 1 Mar to 16 Mar Significant reduction in water consumption due to the rainwater harvesting
    • Building Fabric Performance High levels of insulation Only £180/y savings identified
    • Building fabric performance The building losses less than 1°C over night when external temperatures less than 0°C 21.30°C 20.65°C 23:00 07:00
    • Biodiversity findings All Development stage targets in the bio-diversity action plan met, including: • No loss of amphibian breeding, foraging and shelter habitat. • Retain and protect hedgerows where practicable • Contribution to local black poplar target • No net loss of black poplars on site Good management process established for Operational targets. • Some tension between pest control and biodiversity. • Site requires specialised maintenance to deal with green wall and swale
    • Customer feedback – First stage • A customer survey undertaken at Cheshire Oaks & Warrington • Customers asked their view on sustainable features • Was the store found to be any more appealing? • Did the design of the store affect their decision to visit?
    • Some key findings from the spring survey  The vast majority like the layout, calling it “spacious” and enjoying the “wide aisles”.  People also particularly like the “airy” and “spacious” feel.  96% of people found the temperature in store to be just right throughout.  40% of people knew about rainwater harvesting – and referred to it directly as a ‘Sustainable feature’.
    • Some key findings from the spring survey (continued)  40% of people had noticed the biodiversity and landscaping outside – the Green Wall, Swale, or Wildlife Meadow.  84% of people thought there was good daylight in Cheshire Oaks – the majority of those who did not, wanted more  87% of customers found the artificial lighting to be good.
    • Lessons learnt from Cheshire Oak Key factors that contribute to the successful operation of the building: • Clear vision for the building expressed through Plan A and the Sustainable Construction Manual. • Detailed hand-over process with clear operation and maintenance manuals. • Post occupancy workshops which bring together designers, contractors and facilities staff to examine the building’s performance in use.
    • Lessons learnt (continued) The fundamental principles of energy efficient building design have been well adhered to • Good insulation • High levels of air tightness • Limited thermal bridging • Maximise natural light • Reduce solar gains • Simple HVAC systems with easy controls
