There are many reasons to use these energy efficient products to provide only heating to a building via the delivery method of air
- Many buildings do not need cooling, for example schools and student accommodation
- Heat pump air conditioning systems offer a simple, flexible and efficient method of delivering heat to a building
- Help with Part L Compliance by removing all power consumption related to cooling

Guide to
Long Term Building EfficiencyPresented by:
Rob Bowden
COPYRIGHT © 2013 MITSUBISHI ELECTRIC EUROPE B.V. ALL RIGHTS RESERVED.
Energy efficient design
• Think beyond design and handover
• Part L 2010 – and beyond
• Tighter targets on carbon performance
• But there is a longer term challenge
COPYRIGHT © 2013 MITSUBISHI ELECTRIC EUROPE B.V. ALL RIGHTS RESERVED.
Existing buildings, new targets
• Government aims to reduce UK carbon emissions by
80%
• Built environment a key part of this target
• Impossible to achieve with new-build alone
• 60% of 2050 commercial floor space was already
built in 2010
COPYRIGHT © 2013 MITSUBISHI ELECTRIC EUROPE B.V. ALL RIGHTS RESERVED.
Long term energy performance
• Refurbishment and long-term efficient
operation are crucial
• Building owners and operators need to pay
close attention
• Benefits are reduced carbon emissions and
lower energy costs
COPYRIGHT © 2013 MITSUBISHI ELECTRIC EUROPE B.V. ALL RIGHTS RESERVED.
Long term energy performance
How the figures add up:
• About 40% of a building’s operational costs are related to energy
• Around 80% of the total costs of a building occur during its operation
• Half of those are energy-related
• Only around 20% of costs during the design and construction phase
COPYRIGHT © 2013 MITSUBISHI ELECTRIC EUROPE B.V. ALL RIGHTS RESERVED.
The good news
• The advantage is that users and owners have control over operational costs
• Energy is one of the most controllable overheads
• Several important areas of energy usage:
• Heating
• Hot water production
• Lighting
• Cooling and ventilation
• Auxiliary energy (eg for PCs and other
office equipment)

Step-by-step efficiency
Achieving long-term efficiency means examining all these areas:
1. First step – find out where energy is being used
2. Metering and sub-metering
3. Measure, monitor and then manage

Quick wins are possible
Three main opportunities to save energy:
1. Better control (turn down or switch off when necessary)
2. Good maintenance
3. Refurbishment or replacement
COPYRIGHT © 2013 MITSUBISHI ELECTRIC EUROPE B.V. ALL RIGHTS RESERVED.
Quick wins are possible
Quick wins for early payback:
• Get control of your controls – avoid energy drift
• Meter and measure
• A walk-around check pays dividends in energy saving
• Sensors – working and correct positioning?
• Manual overrides – are they off?
• Check timers – are they set to match office hours?
COPYRIGHT © 2013 MITSUBISHI ELECTRIC EUROPE B.V. ALL RIGHTS RESERVED.
Make the most of your control system
Understand the capabilities of your control system:
• More equipment supplied with advanced
built-in controls
• Air conditioning can be linked to lighting
• Seven-day time clocks included
• Make sure the FM team knows what can
be achieved
COPYRIGHT © 2013 MITSUBISHI ELECTRIC EUROPE B.V. ALL RIGHTS RESERVED.
Maintaining savings
• Good maintenance will save money in the long-term
• Energy consumption of an air conditioning system can increase 60% without regular maintenance
• Cutting maintenance is a false economy
• Start with simple checks
• Comply with legal requirements on air conditioning system checks
• Reduce heating by a few degrees – but talk to
occupants first
COPYRIGHT © 2013 MITSUBISHI ELECTRIC EUROPE B.V. ALL RIGHTS RESERVED.
Quick wins – low and no-cost ideas
• Set time clocks to match building use
• Limit set-points on air conditioning (21oC and 23
oC)
• Lock controllers
• Ensure lighting is off at night
• Get staff buy-in for energy saving measures –
this can greatly increase your success in reducing energy waste

Long-term energy management is a virtuous circle

New technologies
• Refurbishment and replacement –
next steps
• Once savings with existing equipment have
been optimised
• Replacing older technology may be a useful option to
consider
COPYRIGHT © 2013 MITSUBISHI ELECTRIC EUROPE B.V. ALL RIGHTS RESERVED.
Energy-savings options
Heat recovery technology:
• Substantial savings
• Recovers ‘waste’ heating or cooling energy
• Applies it to incoming air
• Reduces the need for mechanical heating and cooling
COPYRIGHT © 2013 MITSUBISHI ELECTRIC EUROPE B.V. ALL RIGHTS RESERVED.
Automatic waste reduction
Consider technologies that prevent waste automatically:
• Window controls that shut down air conditioning automatically
• Prevents running of heating/cooling with open windows
• Particularly useful in the hotel sector
COPYRIGHT © 2013 MITSUBISHI ELECTRIC EUROPE B.V. ALL RIGHTS RESERVED.
New system, new energy savings
Replacing older air conditioning systems:
• Modern equipment is substantially more energy efficient
• Can see 45–50% energy savings against ten-year-old equipment
• Existing pipework and wiring may be used in some cases
COPYRIGHT © 2013 MITSUBISHI ELECTRIC EUROPE B.V. ALL RIGHTS RESERVED.
Replacement
Other reasons for new air conditioning systems:
• New rules on use of R22 – phase out of
virgin refrigerant
• Complete ban on all HCFC by January 2015
• Price of R22 already rising as supplies of recycled R22 diminish
COPYRIGHT © 2013 MITSUBISHI ELECTRIC EUROPE B.V. ALL RIGHTS RESERVED.
Replacement
Substantial savings can be made by replacement of old air conditioning:
• HSBC bank invested £16 million on new equipment at 800 branches
• Other technologies such as heat recovery and new controls
• Halved energy bills at branches
• Saved over £2 million a year on energy costs

Thinking of renewables?
• Heat pumps offer a useful solution for
commercial buildings
• Low carbon solutions
• Lower energy use on heating which accounts for
half of energy used
• 1kW of electrical energy input = 3.2kW heat produced
• Commercial solutions now available
