Birmingham – Scale of Opportunity
Public Sector• Local Authority Offices• Schools• Health Buildings• Colleges & Universities • Leisure Buildings
Private Sector• Industrial• Commercial• Retail• Leisure
Non-domestic buildings account for circa 20% of carbon emissions
Birmingham’s business energy costs are £500m pa
> 40,000 businesses in Birmingham
450 schools with 10% growth required
BES - 1000 non-dom buildings originally envisaged in 8 yr period

• Few case studies to date – although a number of lighting retrofits
• BES Phase 1 – PV on industrial units
• DECC ‘Go Early Pilots’ : Birmingham : Schools & Community Centres Solihull : Library (listed building) – switch heating from electricity
to gas or biomass – 39% - 62% carbon savings – 5-7 yr payback : School 1 – replacement boilers 4 yr payback - 50 Kw PV – 7 yr payback (FiT) : School 2 - effective energy bills reduced to zero thro’
biomass RHI and PV (FiT)
• Solihull College – Lighting, BMS upgrade, Insulation – under 5 yr payback

Minimum standards
• All marketing particulars of property must include an EPC• Minimum building energy performance standards by 2018 :
Current intention - minimum EPC rating of E (18% of stock)• ‘Building the Future Today’ (Carbon Trust) – EPC rating must be 4
grades higher by 2050 than today
Resulting in risks to property owners of : Obsolescence and loss of value Negligence claims through not exercising.. ..’the fiduciary duty of
trustees and investors to understand and consider sustainable investment issues when looking at investment in real estate ‘.

Barriers to non-dom retrofit
• Long lifecycles of buildings• Multiple ownership/occupancy & tenancy• Operational Issues - disruption• Information related issues – poor data on energy use• Commercial Issues – varied and uneven distribution as between landlord
and tenant of costs, benefits and control over energy use• Legal Issues - constraints within leases on how costs and benefits can be
allocated between tenant and landlord• Cost of Finance• Reversion Risk• Low awareness and apathy

Practical Areas for Action – 10 Point Checklist
• Sign a Green Lease• Sign a Green MoU• Set up a Green Group for building(s)• Measure & Report Performance• Use ‘Smart’ Metering• Undertake an Energy Audit• Undertake no cost initiatives• Undertake Retrofit Works• Celebrate & Communicate Results
