Energy use and optimisation in commercial
buildings and how investment decisions can
be assisted
My background
• Aerospace degree specialising in fluid and thermo dynamics
• 5 years working for Michelin Tyre PLC
– Fluid design engineer typically designing building services
– Started to do more and more energy efficiency work after identifying
numerous opportunities
• 5 years working for JBA Consulting carrying out work for:
– Councils
– Commercial organisations
18
Presentation content
• Common problems leading to poor efficiency
• Optimisation of energy usage
• Assessing investment decisions
19
Energy use in commercial buildings
• Having assessed the energy use of numerous buildings / processes:
– Manufacturing sites
– Offices
– Community use buildings
• Common problems:
– Building managers / users not understanding their installed equipment
– Oversized equipment from poor specification or reduced loads.
– Building or equipment users that are able to override settings and many
other bad practices – all leading to poor efficiency

There are things you can do
• Optimising (reducing) energy usage and considering alternative
technologies or fuels can lead to significant cost and carbon savings.
– It is vital that we look beyond simple payback when considering these
options as viable solutions may well be dismissed otherwise.
• However, alternative technologies are not always required.
•
Careful sizing of equipment through accurate design
•
Considering a duty / assist approach, and
•
Automated management systems which optimise and prioritise
Can also lead to significant savings.
23
Investment decisions
By considering whole life cycle costs
and presenting other financial
indicators to decision makers, projects
are likely to be looked on more
favourably.
24
Energy use in commercial buildings
• Designers need a new approach to specifying and sizing equipment.
– Focusing more on whole life costs, less on initial capital costs.
– The proposed options should be shown to be financially viable.
» In a way that is comparable to other investment options
• Buildings need to be more intelligent, self-sufficient and sustainable.
– This includes being less easy to impact by staff / members of the public
• In the future the energy performance of a building will have a direct
impact on the resale value and rental income of a building.

Unlocking Investment in

What is the BPF?
> ‘Representative organisation for those
who own and invest in property in the
UK.’
> ‘We aim to create the conditions in which
the commercial property industry can
grow and thrive, for the benefit of our
members and of the economy as a
whole.’
The voice of property
Traditional Barriers to Energy
Efficiency Investment
> Path dependency
> Operational issues
> Information related issues
> Commercial issues
> Legal issues
The voice of property
So…
> Whilst unlocking investment in energy
efficiency is important, there are other
barriers we need to negotiate in
parallel to ensure a) we are able to
invest and b) reap just rewards.
The voice of property
Overcoming Path
Dependency
> Question mark over requirements for
consequential improvements within Part L 2013
on major renovation
> Green Deal launched in October 2012, but loan
rates unattractive for larger owners and nonfinancial barriers remain (operational issues,
legal issues) which have been left to industry to
solve
> Non-invasive retrofit solutions?
The voice of property
What if we made
performance more visible?
> Traditionally, energy performance has remained hidden because of complex
energy procurement use and control patterns. However, efforts are
underway to encourage greater release of information:
> Display of energy performance certificates (likely theoretical ratings) in
commercial properties visited by the public >500m2 where one has
previously been issued
> Article 7 of the Energy Efficiency Directive requiring energy efficiency
audits for ‘large organisations’ and roll-out of smart metering
> Still potential for a roll-out of operational ratings to non-public sector
occupied commercial buildings
> Proposals for mandatory emissions reporting for listed companies
(possibility of extension to non-listed large companies from 2015)
> CRCEES League Table
The voice of property
What if sustainable buildings
performed better financially?
> Valuation Information Paper 13: valuation
practice may begin to suggest that sustainability
performance is a facet of prime real estate, and
that a failure to mitigate environmental risk may
lead to fiduciary risk
> ECOPAS
> Energy Act 2011 may specify that poorer
performing buildings are unlettable pending
upgrade
The voice of property
Retrofit During Building
Occupation?
> Disruption caused by retrofit can act as a
disincentive
> Leads to landlords and tenants preferring to
undertake retrofit when buildings are vacant
> But non-invasive retrofit is possible. Potentially
to be explored via Institute for Sustainability
Climate KIC (e.g. abseiling rather than
scaffolding, LED replacement lamps for fittings)
The voice of property
Can we green the lease?
> The lease’s approach toward retrofit (is it an
improvement or a replacement? Cost implications)
> Green Leases: sign in haste, repent at leisure.
MOUs more popular but non-binding and time
limited. BBP experiments showing some successes
and no need to wait for leases to come up for
renewal
> More fundamental reform of L&T Act? Not there yet
but unpalatable truth may be dawning
