  • One of the key stages of BIM currently being heavily implemented due to its relative infancy is the pre-build engagement, optimising and specifying stage. During this process BIM requires a collaborative 3D model with all materials and items containing specification information with them.Mitsubishi Electric provide Autodesk Revit (most popular software for this stage) models for the majority of our equipment. They not only contain 3D geometric data but also specification data such as capacity, sound levels, refrigerant charge and electrical requirements.
  • Whilst not fully utilised yet, an ideal BIM building project would fully incorporate energy analysis to aid in the selection the correct solution for the building.Accurate and dynamic modelling of performance of heating, cooling and ventilation equipment within buildings goes a step further in understanding true efficiency and effectiveness. Environmental Design Solutions Ltd (EDSL) has partnered with Mitsubishi Electric UK to enable full integration of City Multi, Mr Slim, Lossnay and Ecodan products within the Tas Thermal Analysis Software.The software enables systems to be simply added to a project and the buildings performance to be modelled with the actual equipment to be installed. The software can not only size equipment but can demonstrate energy consumption and efficiency and create Part L compliance reports and Energy PerformanceCertificates (EPCs).
  • At the start of the BIM process, specification / detailed design etc we have some new products and solutions which can push to achieve the most efficient buildings
  • The YKM models for the UK replace the current YJM models but only for the High CoP EP range of outdoor units. The YKM is available for both the Y Series (heat pump) and the R2 (simultaneous heating and cooling) range of equipmentThe standard range of City Multi stays as it is (YJM)
  • Seasonal efficiency is becoming the new driver and units above 12kW in capacity will be affected from 2015 by the revised EuP Eco-design directiveMitsubishi are introducing the new YKM range as a starting point for the seasonal range of VRF equipment which has ben introduced in to the UK.Comfort,Control and Flexibility bring together VRF as a total integrated solution
  • The majority of the time A/C systems don’t run at full capacity during the working seasonThe graphs for the cooling and heating represent the respective seasons.As the graph shows the VRF system will work at part load for the majority of the time and therefore work for more efficiently.So in the UK typically the cooling season is somewhere between 15 and 30 deg C and for the heating season between 0 and 10 deg c, Although we may get conditions outside these ranges they are rare and tend not to last more than a few days in a year.
  • A lot of the drivers for more seasonal efficient equipment are been driven by the some of the legislation shownFor EuP the Eco-design requirements will change in 2015 to include all units above 12kW (with no upper limit) – This will affect the larger split range of equipment and have a big impact of the VRF/VRV equipment brought in to the European Market from this date.Our own Green Gateway also pushes systems that are based around real life seasonal performance
  • NEW Optimised Energy Saving Cooling ModeAs the ambient temperature in the cooling mode reduces (i.e early morning or late afternoon) the system alters the refrigerant temperature which results in a milder off coil temperature atthe indoor unit, this improves efficiency, and gives a more Comfortable Internal Condition
  • The standby power has an impact on the overall running costs of a systemThe new YKM saves an estimated 20% saving over the YJM model it replaces when the system isn’t operating and is sitting in standby.
  • There are many reasons to use these energy efficient products to provide only heating to a building via the delivery method of airThey offer the inverter technology and the efficiency of our split system range but as a heating only optionHeating only splits are one of the most efficient solutions available to provide heat to a building.
  • Available to order nowThe heating only splits come in a range between 3.5kw to 45kwThe model reference is defined as a CUHZ and is the same spec and price as the heating and cooling modelsThe full indoor range is available for the CUHZ range of splits alsoA PAR-31MAA controller must be used for the heating only function to operate correctly. If other controllers are used the function cannot be guaranteed.
  • Controls are a critical part of controlling a buildings services and it is not just crucial to ensure the correct controls are selected at the start of the building process. It is key to ensure they are installed and commissioned correctly and then continually monitored, reported on then controlled further throughout the operation of the building to ensure they are performing as the building and its occupants require in the most efficient manner.Controls therefore are very important in all stages of the BIM process and also help with optimising with Government Soft Landings.
  • Provisional information for the replacement of the M-Net PAR-F27MEA controller which will be released in October 2013The new controller has a touch screen and backlight as standardThere is also a PIR occupancy sensor within the remote and a screen brightness detectorWhen the PIR occupancy sensor detects that a room or zone is unoccupied the controller uses an internal function to reduce the energy consumption used.The remote can also detect both temperature and humidity It can control up to 16 indoor units in one groupAt the bottom of the controller is a colour indicator which uses lights to show what the system is doingOrange shows the unit is heatingBlue shows the unit is coolingGreen – Fan (or dry)Red unit in faultFurther details and features will be made available for the PAR-U01 as soon as they are made available
  • New simplified remote controller is now available and replaces the outgoing PAC-SE51CRAIdeal for Hotel Bedrooms, Meeting Rooms or OfficesNew design with flush fitting (no back box required) Back light as standard with the addition of a mode and louvre button with a brilliant white coverAvailable Ex Stock
  • In October we will also be adding a variance to the PAC-YT52CRA called the PAC-YT52CRASSame flush fitting, backlight and Mode button is availableHowever the louvre button has been removed for the main purpose of hotel bedrooms that have ducted fan coils fitted where a louvre button is not required.The design is a silver frame with a black face.This is for the UK Market requirements.
  • MELCloudis a new Cloud based solution for controlling your Mitsubishi Electric Air Conditioning systems either locally or remotely by PC, Tablet or Smartphone via the Internet. The MELCloud service can be accessed by a wide range of the latest Personal Computers (PC), Tablets and Smartphones from the leading manufacturers. The application detects which device you are using and dynamically adapts the display to maximise the screen available.All the main mobile device manufacturers are supported by MELCloud, either by dedicated applications which can be downloaded free of charge from the various App stores or if your device is not supported by App, then the MELCloud Web application will work on most devices via one of the latest Internet browsers from Microsoft, Google, Apple and others.MELCloud allows you to take control of your Mitsubishi Electric systems from anywhere in the world as long as you have Internet access. So forgetting to turn off your Air Conditioning when you are away on holiday is no longer a problem.MELCloud has been designed for a wide range of users from single users with single Air Conditioning systems in a single building, up to larger user who may have multiple properties and multiple systems that they wish to monitor and control.Whichever type of user you are, MELCloud can provide you with required control and access you need for modern living.
  • The MELCloud includes such features as:Unit control - allowing the selection of system on/off, operation mode, fan speed, vane (both horizontal and vertical), room and set temperatures.A reports section lists all the available reports that you can see and access. This is where more detailed information regarding the operation and status of your equipment will be shown, such as error logs.Live Local Weather information shows the current and future weather predictions for the location via a third party weather data service.Frost Protection allows you to set a minimum room temperature that if detected, will then initiate the system to switch on and to warm the room to protect the room contents or building fabric from a low temperature.Timer Function allows you to set a control event condition based on a 7 day weekly schedule. A Holiday Mode allows you to tell the MELCloud service about any period of non use which you want to set to prevent waste of energy or unauthorised use of the system whilst you are not at the property
  • MELCloud – stage 1 a/c (june 2013) – We have a compatible list of the M Series and Mr Slim units that can be used on MELCloud (to be issued shortly)stage 2 Ecodan will be available - End 2013 stage 3 Finally VRF – likely to be early 2014
  • You will need to purchase a WiFi Interface (MAC-557IF-E) to connect your system to MELCloud, You will also need a compatible Mitsubishi Electric system to connect to the MELCloud service, there is a list of compatible models available from us. Compatible systems will have a CN105 terminal which the WiFi Interface MAC-557IF-E can be connected to.Please contact your local Mitsubishi Electric branch, Sales Representative or Distributor for more information on how to purchase this.

    23. 23. COPYRIGHT © 2013 MITSUBISHI ELECTRIC EUROPE B.V. ALL RIGHTS RESERVED. Guide to Long Term Building Efficiency Presented by: Rob Bowden
    24. 24. 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
    25. 25. 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
    26. 26. 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
    27. 27. 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
    28. 28. 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)
    29. 29. COPYRIGHT © 2013 MITSUBISHI ELECTRIC EUROPE B.V. ALL RIGHTS RESERVED. 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
    30. 30. COPYRIGHT © 2013 MITSUBISHI ELECTRIC EUROPE B.V. ALL RIGHTS RESERVED. 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
    31. 31. 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?
    32. 32. 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
    33. 33. 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
    34. 34. 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 23oC) • 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
    35. 35. COPYRIGHT © 2013 MITSUBISHI ELECTRIC EUROPE B.V. ALL RIGHTS RESERVED. Long-term energy management is a virtuous circle
    36. 36. COPYRIGHT © 2013 MITSUBISHI ELECTRIC EUROPE B.V. ALL RIGHTS RESERVED. 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
    37. 37. 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
    38. 38. 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
    39. 39. 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
    40. 40. 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
    41. 41. 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
    42. 42. COPYRIGHT © 2013 MITSUBISHI ELECTRIC EUROPE B.V. ALL RIGHTS RESERVED. 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
