Future FM Objective and WPs
• Objective: improve energy performance of non-domestic
buildings by focusing on analysing multiple data streams
that are captured by systems embedded in these sites
• Work Packages:
WP0 – Virtual Test Bed Development
WP1 – Data mining for FM
WP2 – Model Design Through Global Sensitivity Analysis
WP3 – Smarter Control Algorithms for FM
WP4 – New business plans for building management
• Partners
Modelling UK electricity prices
• UK consumers face rising electricity costs

•
Projected +50% rise from 2011 to 2020
Costs and policies guaranteeing security of supply
Billing structure is complex and evolving
Customers need knowledge to make informed decisions

Some thoughts
• Comprehending energy bills is a complex task
• Updates on energy markets and policies is key
• Regional real-time prices of electricity allows us to
assess carefully cost reduction investments and hence
define best practice on managing buildings/assets
• Energy cost foresight allows stakeholders to develop
long term investment plans

WP0
Virtual Test Beds
• Objective: Simulate indoor thermal
environment and HVAC performance of
case study buildings
WP2&3
WP1
Data Mining for FM
• Objective: Understand HVAC performance and detect faults
using data gathered from FM logs, BMS, and occupational
data collected
WP3
WP2
Model Design Through Global Sensitivity Analysis
• Objective: Apply global sensitivity analysis to HVAC systems
to identify most important parameters and develop reduced
order models
WP3
WP3
Smarter Control Algorithms for FM
• Objective: Feed WP1&2 into a model predictive control
strategy for test bed buildings
WP4
New Business Plans for Building Management Services
• Objective: Review business models that provide added value
to building owners and operators, while enhancing services
offered by energy service/BMS providers
