Past – Present - Future Copyright: Jeremy Towler
Why do buildings matter? • 60 -90% of our time spent in buildings • Live - learn - work - create - heal - consume - entertain… • Buildings and construction together account for: • 36% of global final energy use and • 39% of energy-related CO 2 emissions 1 1 Copyright: Jeremy Towler When upstream power generation is included.

In buildings we meet – collaborate - consume • We want to: Optimise this experience Find the best place to collaborate Locate each other & equipment Be safe - secure - comfortable Enhance productivity and creativity through greater comfort and convenience • Attract and retain talent • Stay flexible • • •
Buildings protect valuable assets • Hospitals • Data centers • Industry • Laboratories • Food & pharmaceuticals • Museums and galleries Copyright: Jeremy Towler
Technology keeps us safe – secure comfortable
What do these solutions comprise? • Switches, sensors, cameras, readers, controllers • Motors, actuators • Valves, pumps, fans • Microprocessors & computers • Software (local & remote) • Services • Advice & design • Installation & commissioning • Maintenance & optimisation
Networked systems
We shape our buildings; thereafter they shape us. Winston Churchill
New technologies are human-centric • Indoor location • Personalisation • Self-learning, adapting • Software & cloud-based • App-based • Use analytics • Artificial Intelligence (AI)
Construction costs • Example for a • 15 -20 storey building • Floor area 250, 000 - 300, 000 ft 2 (23, 000 – 28, 000 m 2) • Total cost $40 -50 m • Costs and splits vary by building type and location (Based on various sources)
Building lifecycle • 10 – 15 years between refurbishments • Some 80% of total building lifetime costs result from building operation • Move away from CAPEX to OPEX • Smart buildings do not have to cost more than traditional! Copyright: Jeremy Towler
Enormous renovation potential • 80% of the buildings that will exist in 2050 have already been built • Energy Performance of Buildings Directive (EPBD) Copyright: Jeremy Towler
Operational costs The 3 -30 -300 ratio • Rule of thumb: Total occupancy costs per ft 2 • $3 for utilities • $30 for rent • $300 for employee costs (salaries, benefits, etc. ). • So a 10% • Increase in energy efficiency yields $0. 30 savings per ft 2 • Decrease in rent would save $3. 00 • Gain in productivity is worth $30! Copyright: Jeremy Towler
Internet of Things • Individual building devices becoming intelligent • Processing data “at the edge” • Transmitting info to the “cloud” • Remote analytics of “big data” • > 50% of world’s data created in the last year! • But < 0. 5% was analysed or used
Digital twins • Design twin • Construction twin • Operational twin • BIM – Building Information Modelling
The future • Sustainability, performance, reliability • Buildings as an integral part of smart cities • Integrated to a smart energy grid • Buildings as “prosumers” • Integrated to a smart transportation infrastructure • Integrated with our individual profiles Copyright: Jeremy Towler
