Bought a domestic
appliance recently?
What energy rating was it?
If you really wanted to buy
an F-rated appliance where
would you go?
Bought a property recently?
What energy rating was it?
If you really wanted to buy
an ++A rated building could
you?

11. • EPBD, directive 2002/91/EC
• EPCs
• DECs
• Air Conditioning inspections

12. EPBD: II
MINIMUM ENERGY EFFICIENCY STANDARDS (MEES)
• The Minimum Energy Efficient Standards (MEES) came into force in 2016 under the Energy Efficiency Regulations 2015.
• From 1 April 2018 landlords of non-domestic private rented property are prohibited from granting new lease of any “sub-standard”
properties.
• From 1 April 2023, these requirements will also apply to all existing lettings.
• A number of exclusions and exemptions that will enable a landlord to let, or continue to let, a substandard property include leases of
less than six months or more than 99 years, properties where an EPC is not required. Otherwise a landlord may be able to register an
exemption. The key exemptions are:
• The seven-year payback test: where the capital cost of required energy efficiency measures is not cost-effective within a seven-year
payback period.
• Third-party consent: where despite “reasonable endeavours” necessary third-party consents to carry out the energy efficiency
improvements cannot be obtained.
• Property devaluation: where the measures proposed would reduce the value of the property by 5% or more.
• Recently becoming a landlord (a temporary six-month exemption): this applies in limited circumstances, including the grant of a lease
due to a contractual obligation, pursuant to the Landlord and Tenant Act 1954, or the grant of an overriding lease under the Landlord
and Tenant (Covenants) Act 1995.
EPBD (Directive 2010/31/EU)
or EPBD II

13. Community Goals
• Reduce pollution, CO2 air quality etc
• Reduce demand on the energy network,
energy security
Landlord
• Capital value/return on investment
Tenant
• Opex savings
• Enhancing Control
So why make buildings meet MEES

15. • auditing portfolios to understand which
properties are within scope of the MEES
Regulations and whether exemptions
might apply
• check whether the EPC ratings for their
properties are correct especially E, F & G
• understanding how lease terms, break
dates, renewals dates and planned refit
periods fit with the MEES timetable
• reviewing their leases to understand their
rights.
Landlords can prepare now by:

16. • 85% of non-domestic properties can be
brought up to an E EPC using measures
that meet the green deal’s golden rule.
• Which is “ The expected financial savings
must be equal to or greater than the costs
attached to the energy bill”

17. Building envelope:
• Insulation roof coverings and cladding – saving
<20%, cost and disruption medium/high, pay back
poor
• Glazing average, saving <30% , cost and
disruption medium/high, pay back poor
• HVAC & controls, saving >10-30%, cost and
disruption low, payback good
• Lighting & lighting controls, saving >30%, cost
and disruption medium, pay back excellent
• Renewables: PV, solar thermal and wind,
saving<20%, cost and disruption high, pay back
poor
Renovation Measures

18. Relationship between Lighting
HVAC, IT and Occupancy Loads

19. • Installing LED lighting can be a cost
effective, quick fix
• Lighting controls can save run time and
maintenance costs
• Double whammy, saving on lighting load
also saves on 10-15% on HVAC in an air
conditioned bulilding
Lighting

20. • New IT is always cool
• IT department pay for it
• Saves power (you are metering the under
floor power separate from the lighting and
HVAC?)
• Saves more power on HVAC
Or
• You can save money on rent by increasing
occupancy!

• Targeting and Monitoring
• Meter it
• Record it,
• MS Excel is your friend
• Normalise it degree days and occupancy
• Publish it
• Inform the end users
• Inform management
• Cost very low, saving30%, payback initially
excellent then tapers off!
