AWARD-WINNING RESULTSOUR CLIENTS HAVE ACHIEVED:
• World #1 status in the Dow Jones Sustainability Index for Real Estate for four consecutive years
• No1 status in the 2012 Global Real Estate Sustainability Benchmark (GRESB) for both office and retail categories – Oceania Region
• 4 CIBSE Building Performance Awards in the last 3 years for energy efficiency
CURRENT CHALLENGESUSING DATA FOR ENERGY EFFICIENCY
• Sustainable Design perceived as a panacea• CHP/District heating schemes poorly metered• Bad implementation = bad data = no savings• Fit for purpose systems and metering• Lack of FM expertise• Big data
COLLECTING BIG DATA
• Multiple User Remote Access via Internet
• Water Meters (Pulse) • Gas Meters (Pulse)
• Direct Access
• Temperature Senso
