Why the Discrepancy?

Goes up to 65% in offices

Bridging the Discrepancy

Gap between predicted andactual performance can be closed

to 5-10%

Untapped Data AssetToday increasing volume of Data is available at every

stage of the building life cycle

Untapped Operational Data

How much data

• Monthly kWh 12 points annually• HH kWh 48 points x 30 days x 12 months = 17,280 points• HH gas, heat… water……. = 50,000 points• Sub-meters, typical new office building might have 50• ……..data points increase exponentially = 2.5 million already• Portfolio of buildings…. 100 buildings large client, hundreds of

millions of data points• What about BMS?

• Typical office building with heating/cooling might have 300 relevant BMS points recording data (5 million for 1 building)

• What are we doing with this data?

Digital Built Britain – BIML3• “The Information Economy Strategy identifies that our

most pressing societal challenges manifest themselves in our cities.

• Rapid urbanisation is a critical issue in emerging markets, which are demanding cleaner, more sustainable and healthier urban environments, with reliable sources of energy and less congestion.

• City leaders around the world are turning to integrated and intelligent smart systems and associated big-data concepts to deliver vital public services”

Digital Built Britain – BIML3

“The ability to measure “in service” performance and compare it to “as briefed” and “as delivered” assets - providing the single biggest opportunity to improve both cost and carbon performance.

The ability to bring together through open data standards from design, construction and operations and across market sectors - offering the ability to analyse and create the learning feedback loops that industry needs to be able to deliver sustainable long-term improvements in asset performance.”

Digital Built Britain – BIML3“Recent work in connection with the Government Soft Landings (GSL) initiative has highlighted that commercial mechanisms are not currently able to facilitate a greater focus on the absolute achievement of performance requirements.

The involvement of multiple parties employed on a skill and care basis makes it currently difficult to enforce performance requirements. This is a partial explanation of the widely observed ‘performance gap’ in buildings and is a key driver behind the introduction of GSL.”

Snippets from ‘what does the future look like’..

• Data-enabled collaborative working in the design, construction and operation of assets enabling best use of capability in the supply chain to deliver value to customers

• Use of data recording asset operation and condition to understand asset performance, define better project briefs and to form the basis of new performance contracting models

• Application of remote monitoring, telemetry and control systems to the real time operation of assets and networks

Data OverloadIncreasing Volume, Variety & Velocity of Data

• Organise & manage it to reduce risk• Make sense of it to find opportunities • Deliver added value and save ££

More data captured and managed = clearer picture of your building’s performance

Using Data to build a complete picture

With Analysis, Data is Powerful

John Lewis York, UK

Outstanding CollaborationCIBSE Collaborative Working Partnership Award

“John Lewis, York slashed its absolute carbon emissions by a massive 43.8%.”

• 4 Year Collaboration: Lateral Technologies, IES & Next Control Systems• Next Generation operational monitoring and energy management• IES-ERGON reads data from BMS and refines it with the design model to highlight

performance gaps

Final Thoughts

Implications• Technology is available now• Barriers = commercial politics & lack of skillset • Owners will start demanding buildings which

operate closer to design predictions – BIML3• Operational Data can feed (or re-seed) into
