Who we are?
• Independent.
• National charity.
• Based in Milton Keynes.
• Established in 1988.
• At the forefront of improving
the use of energy in buildings.
We aim to give people, organisations and governments the knowledge, support and inspiration, to understand and improve the use of energy in buildings.
How we work
to identify and
address market
failures
driving forward the frontiers of understanding,
innovation and practice
to deliver practical projects – using our
experience and technical expertise
to achieve
better
performing
buildings
Who we work with
• Businesses
• Community Groups
• Energy and Facilities Managers
• General Public
• Government Bodies
• Local Authorities
• Manufacturers
• Property Owners, Operators and Landlords
• Research Establishments
• Service Providers
• Social Landlords
• Trade Associations
Commercial and Non-domestic buildings
In theory, theory and practice are the same – in practice they aren’t!
Buildings often don’t perform as expected

Non-domestic energy performance

Committee on Climate Change – 2016 progress
UK non-domestic buildings account for 18% of emissions, 20MtCO2e annually. Non-residential building emissions remain similar to 2003 levels. New policy, stronger implementation and a focus on low-carbon heat recommended.
ESOS – first deadline December 2015
• Required for UK companies (or overseas companies with UK
establishment) that either:
o employ 250 or more people, or
o annual turnover in excess of 50 million euro
• ESOS process includes:
o Energy audits
o Site visits
o Energy modelling
o Opportunity costing
o Reporting
o Optional implementation
ESOS findings
• Energy surveys of existing buildings
typically identify no/low cost savings
of up to 20%
• Larger, longer term projects and
whole building targets in excess of
30%
• Beyond that – low carbon and
renewable energy
• Reducing costs now, reducing risks
around future energy cost and supply
uncertainty
MEES – Minimum Energy Efficiency Standards
• From April 2018, properties with
EPC ratings of F &G cannot be
re-let
• What will be the impact on:
o asset values,
o ‘work arounds’,
o leasing periods,
o rental incomes?
MEES – Minimum Energy Efficiency Standards
• What responses are anticipated?
o Legal avoidance
o Minimum compliance
o Maximised benefits
Maximum benefit: The business case for good building performance
• Reduce cost of occupancy – energy cost approaching rental cost per m2
• Meet growing market demand (1/3 companies expect to have at least
60% of their buildings certified green by 2018)
• Demonstrate impact on health and productivity for developers and
owners – especially in face of increasing ‘occupant power from data’
• Improve staff recruitment, retention and productivity
• Rapid re-letting – lease periods reducing
• Future proofing leases – since trends to reduce emissions continues
• Energy can therefore be a good proxy for major performance
parameters
• And more…
A ‘win win win’ opportunity
• Better for tenants:
• Lower tenant energy bills
• Better working environment leading to improved productivity
• Overall reduced occupancy cost
• Building prestige
• Better for landlords:
• Lower landlord energy bills
• Potential increase in rents due to overall occupancy model
• Potential increase in rents due to building prestige
• More reliable and respectful tenants
• Easier and faster to let space
• Better for councils and area:
• Cross borough programme enhances business destination, increasing inward investment, enhancing
property market
• Improved building stock since MEES suits all types of buildings – older and less sophisticated can rival
‘prestige’ buildings
• Higher rateable values
• Better air quality
• Better environment for all
How to deliver MEES?
• Building and system upgrades
• Management practices
• NEF can help through:
o MEES
o VolDEC
o Energy Audits
o Feasibility Studies
o ESOS / ISO 50001 – Energy Management Systems
VolDEC – www.voldec.com
Developed for tenanted offices in
association with Legal & General
VolDEC – current issues for landlords & tenants
• No split between landlord and tenant energy use.
• Display Energy Certificates show whole building performance only.
• DECs use one benchmark for all offices.
• Cannot show improvements (or lack of) in what each party (landlord and
tenant) controls.
• Many offices are ‘stuck’ at G, and cannot show improvement.
• GRESB – Global Real Estate Sustainability Benchmark is now increasing in
penetration, requiring monitoring.
• VolDEC highlights energy performance as a clear driver for improvement.
• VolDEC identifies anomalies and the need for detailed investigations.
Easy access, quick, low cost
No lodgement, no site visit, no advisory report required
Uses the existing DEC methodology as the basis, with an improved layout
Includes a certificate quality rating: HIGH/MEDIUM/LOW
Better (& improving) benchmarks and categories, that are sector specific
VolDEC characteristics
VolDEC certificate
Legal & General have found VolDEC makes GRESB reporting quicker, easier and less costly.
VolDEC methodology
Statutory DEC VolDEC
Methodology Produced using the methodology described in CIBSE TM47
Produced using the methodology described in CIBSE TM47
Benchmarks Uses CIBSE TM46 benchmarks. This provides only one benchmark for all office types.
Uses ECON19 benchmarks for offices. Provides four different office types plus energy is broken down by end use.
Landlord / tenant split
Unable to provide a separate landlord tenant DEC in the same building
Uses the granular energy breakdown in ECON19 to provide composite landlord and tenant benchmarks for 5 different building scenarios.
