1 IFPI (International Facilities and Property Information Ltd.) are proud to offer this new and unique model to prospective building developers/owners and designers across the international scene. A sister program to IFPI's highly successful 'EstatesMaster' Facilities Cost Prediction and Benchmarking Program 'COMBICYCLE' is a user-friendly web-enabled tool for use at every stage of the development It is available from the twinkle-in -the-client's-eye to last minute alterations to a scheme under construction. For further details about the program, what it can do for you, how it works and how to get a user licence please use the site map on the Home page. Welcome to

2 Why CombiCycle? Combines : Whole-life cost Whole-life sustainability

3 What is CombiCycle? Web-enabled predictive whole-life modelling tool for: cost planning and control resource consumption planning and control evaluating sustainability implications sensitivity testing of cost and environmental impacts

4 Enter web-site – Home If you are intending to use CombiCycle for a new project you need to register here. If you already hold a licence to use CombiCycle for this project you just have to login with the user name and password allocated when your licence for the project was issued

5 About This brand new program has been developed for IFPI Ltd. by Bernard Williams and Malcolm Lay - authors of 'Whole-life Economics of Building Services'. COMBICYCLE ' 'enables users to predict the whole life costs and sustainability of any building type before a single line has been drawn ' and then at any stage in the design process. It may be used to set budgets and to give both the Employers and their designers best- performance targets against which to testsubsequent design proposals. With COMBICYCLE ' you can see the cost effects of different design and facilities management strategies in respect of Maintenance Quality of manufacture Specification of components Performance requirements etc. on the costs and sustainability of all the components and systems over any period you wish to choose.

6 About It is intended to make COMBICYCLE' universally available and internationally applicable. To this end the tool will be dialled up on a pay-as-you-go basis from any developed country by any user. COMBICYCLE' ' will also used as a teaching aid in one of IFPI's in-house Training Programme modules whereby users can learn about whole-life issues whilst testing one or more of their new projects for cost and sustainability against the program. At present this superb tool is only available as part of a consultancy offering but it is being web-enabled for users to access and operate independently - available October 2011.

7 Technological Enquiries IFPI has a team of experienced building and facilities economists on hand at all times to answer your queries about how to use the program. They can also help you with the interpretation of the answers you are getting if they are not exactly what you were expecting or you are not sure how they have been derived.

8 Technical Enquiries The program is hosted on a very secure stand alone dedicated linux server running apache; the application is written in PHP using mySQL databases. The set-up is as follows: User Browser and server hosting the PHP source code and Firewall and 1 server hosting the database. Questions regarding the functioning and updating of the program will be dealt with direct by the programs designers.

9 The CombiCycle Modelling Tool - Capability Applicable from inception to completion Prediction of : whole-life capex/opex cost component life - expectancy resource consumption embodied carbon carbon emissions from energy-in-use other noxious emissions/substances interaction between resource drivers tax implications DCF implications

10 Enter CombiCycle web-site Access to the program is via the Internet Users pay a licence fee per project according to: Size of building Period of use Nos. of seats using the program Users nominate the category and size of building A default analysis of this building category is presented once General Data Entry is complete………

11 The Default Result This is the primary output from the program and shows the whole – life predictions for: - capital construction and life-cycle replacement cost - hard fm service costs - CO 2 emissions from energy-in-use -CO 2 emissions from embodied energy - Sustainability rating ……all this before anyone has even drawn a line on paper!

12 The Default Result This is the Primary Results Screen which is generated as soon as you have completed the General Data Entry Page. However this is just the starting point for exploring the many analysis options available from CombiCycle including the elemental, cash flow and sustainability analyses.

13 Login as existing user……..

14 ……or registration as new user

15 Fill in principal user details

16 Select CI/SfB project category CombiCycle has been pre-populated with detailed whole-life cost and sustainability analyses of all the principal CI/SfB building categories. When you insert the details of the project you are planning a generic analysis is modelled to your bespoke requirements by the program.

17 Building category selected The licence fee is the same for any category of building – it only varies with the size (Gross Internal Area). Having selected the category you then need to purchase the licence. You can do this by credit/debit card if you wish or IFPI will invoice you following a direct application by telephone or e-mail.

18 Calculating the licence fee The licence fee is pre-set according to the Gross Internal Area (GIA), the number of users who will have access to the program for the project and the scope of the Licence. The Licence is either for 1 month (Level 1) or 1 year (Level 2) with options to extend from Level 1 to Level 2 with full credit for the Level 1 fee.

19 Selecting the Licence Level Level 1 is best for users who merely want to carry out feasibility studies on alternative design strategies before committing to a full Project Licence. You have a months use of the program so there is plenty of time to use it for the early stages. Level 2 is for when you are sure the project is going ahead: use it right through design and construction development – and beyond if you have the time.

20 Purchase Licence or review options You can go straight ahead and purchase your Licence for the figure quoted or see what other Licence options will cost. The cost of increasing the numbers of users is not in direct proportion to the numbers involved and may be a better – value option for larger projects. Unless sure you will want the program for more than a month go for Level 1 in the first instance ; you convert to Level 2 later if you want to.

21 Licence fee calculated You can see what the fee will be for each level by clicking on the Price Calculator tab. You can select any number of users within a licence fee for a specific project. Only one user can work on a particular survey at any one time but Individual users may also Copy and Save project surveys to work on for specific aspects of the project e.g Sustainability ratings or particular elemental costings.

22 Payment on-line You can purchase a Licence on-line or, if you prefer, do so by phone, e-mail or general post. Once licensed you will be given an access code to activate the program; this will then take you to the Control Panel from where all survey creation and navigation commences.

23 Create a new project Having completed the purchase you are ready to set up the details of the project you are planning to build. When you select New Project you will be asked to name the Project and the Building to be surveyed – see next screen.

24 Naming the project The GIA is automatically introduced from the details given on the Licence application. The text on the screen explains what you may and may not do here. After naming the Project and Building you will be taken straight to the General Data Entry screen

25 General Data Entry At this point you are now just ½-hour or so away from having a full-blown whole-life cost and sustainability prediction of your selected building. But first you need to provide some simple but very important information about the sort of building you are planning. The program will then calculate the quantities and costs based on the Default building specification and the data you provide here.

26 Physical Dimensions The first folder requires you to provide the program with sufficient indicators of the probable shape and nos. of storeys etc. to generate a reasonable projection of the quantities involved in constructing each of the building elements. Most of this data may be updated in later surveys so you dont need to worry if you dont have the precise details to start with.

27 Physical Dimensions The Helptexts for each item will clarify any queries you may have about providing the data. The GIA is automatically introduced from the data you provided at the Licence application stage. You may not change this by more than +/- 10% without the formal permission of the Licensor but all the others may be adjusted in later surveys.

28 Geographical data The Location is fixed once you have inserted it – again the Licensor will not refuse a reasonable request to allow you to alter it. The regional cost index is shown and this can be overridden. The effects of orientation will be included in the next version of CombiCycle as will the effects on the external services of the distance from the boundary – i.e. in the External Works and Services element.

29 Occupancy data The effect of the numbers of users, contractors, visitors the building on the extent of services, cleaning etc.will be incorporated in the next version of CombiCycle. However the hours in occupation is already functional and adjusts the predicted amount of energy consumed and the maintenance and cleaning of the building.

30 Design attributes The performance level pre- selected in the Default survey will be typical for a building of the category chosen. By altering this you raise or lower the performance of every component; where this impacts on cost, maintenance, energy consumption etc. the program automatically makes an appropriate adjustment.

31 Refining the fm predictions – work in progress. The prototype version of CombiCycle sets the maintenance, cleaning the same quality and cost index as you selected for the building itself. This is already adjustable for each component but the upcoming Version 1 of the program will allow you to set these factors independently in a folder dedicated to each of the facilities services. You will also be able to override the assumptions by Element, Sub-element, System or Component.

32 Key analysis details You can set all of these factors where they are live- as they will be future versions of CombiCycle. The Preliminaries on new construction (and on replacement in the next version) may be set as a percentage here; however the Preliminaries have been included in the same format as the other building elements in the upcoming Version 1 of the program enabling you to select options and quality.

33 Fail-safe navigation CombiCycle is designed to be very user-friendly and that includes making sure that you dont accidentally navigate away from a part of the program you are working with. You navigate through the General Data Entry folders using the menu (top-left); each topic turns from blue to red as it is addressed and you get this warning if you try to navigate through the menu using the next tab.

34 The Default result As soon as you have completed the GDE folders and clicked next you are taken immediately to the Results screen. Here the program displays the complete set of whole-life cost and sustainability predictions based on the typical Default specification and the particular data you have provided in the GDE folders. (This screenshot actually shows a later survey by the user based on this Default ). But this is just the entry-point to a far more detailed set of analyses instantly available.

35 Navigating Results Screens Having reviewed the overall results you now have 3 further options: the Element Review, the Cashflow Review and Survey Management. Selecting Element Review will take you to an Elemental Analysis of the cost and sustainability predictions relating to those results. Remember, at this stage you are still reviewing the typical Default specification but it is now framed in the bespoke data you entered on the GDE page

36 Elemental Cost Analysis – Primary Elements etc. The Superstructure Elemental Cost Analysis opens up at Group Element level from where you can explore in depth by cascading through the options available. You can keep going right down to the full component level reviewing one topic at a time as you go or go directly to the hierarchical analysis where you can see the whole picture in one place – albeit a lot of it and less easily navigated. Again you can export to Excel for ease of access to the detail and easier navigation

37 Elemental Cost Analysis – 2 Options The Element Review can also be accessed directly at any level in the elemental hierarchy. You simply click on one of the 2 tabs giving you the choice.

38 Component environmental analysis The Embodied Energy per component in each element is shown on this part of the analysis together with the predicted CO 2 emissions and its contribution to the Building Sustainability Rating /10. Version 1 will show a Rating at each level in the hierarchy as well. The quantity of each component as predicted by the program is also shown. Other systems are able to calculate the CO 2 values for individual buildings but CombiCycle does so for any building of any shape or size more or less instantaneously. Clearly this makes sensitivity analysis a quick and straightforward task – as well as a very accurate one.

39 The Element Review options The note on this page is self-explanatory

40 Component environmental analysis The values assessed for each component over the analysis period (selected by you on the General Data Entry screen) are given under these headings. In the Ratings the score is better when the number is high. The methodology by which these results are achieved is described later in this presentation.

41 Viewing the Cashflow projections Another option available at this initial stage is to review the Cashflow projections for the schemes Default analysis. The results reflect a building of your selected shape and size but are still, of course, based on the Default specification of the components. At the next stage this screen can show the predictions for your bespoke requirements.

42 Cash Flow Projection – life-cycle replacements and facilities services When you open the Cash Flow you have the option of opening it up to show the detail for the number of years you have selected. To do so click on Show Years This screen shot shows the cashflow at component level.

43 Cash Flow Projection – life-cycle replacements and facilities services This screen shot shows the cashflow at component level after opening up to the specified number of years. Later, when you have created your bespoke survey, you may use this screen to build your Asset Register. Version 1 will also offer Discounted Cash Flow calculations for any rate of return.

44 Cash Flow graph Many people like to have a visual image of the cashflow; there is access to this image via a tab Cashflow Graph on the Cashflow Review screen itself. Upcoming versions of CombiCycle will incorporate dcf at your chosen rate and any Corporation Tax relief available plus.VAT.

45 Survey Management – you take over Now you have seen the detailed output from the program in respect of the Default survey you will certainly want to see what specifications have been used to reach these results – and to bespoke them. By clicking on the Survey Management tab on the Results screen the full capability of CombiCycle will be at your disposal.

46 Survey Management – 3 choices At present you only have the Default survey to work with but you will obviously want to see what is going on in it. There are 3 options to open up the Default survey: Copy and Edit, View Results (i.e. back to where you just came from) or View Answers. Edit & Copy lets you set about adjusting the specification to your specific requirements; it also saves the Default and gives your new survey a title.

47 View various stages of the Elemental hierarchy You can access the program at any level I,e, Group Element, Primary Element, Sub-element, System or Component. Filters dropping out of each level will allow you to open up the contents of topics under the headings.

48 Viewing the Group Elements By clicking on any of the Group Elements you can call up the Primary Elements within them. So, for e.g. if you click on Superstructure you will be able to access all its Primary Elements……

49 Viewing the Primary Elements ….or you can go straight into the filtered list of all the Primary Elements and explore any one of them for the Sub- elemental content. In this screenshot the Wall Finishes (part of the Group Element Internal Finishes) is being selected; when it opens up you will see the extent of this Element and the Sub-elements, Systems and Components it comprises.

50 Reviewing the Primary Elements in a Group Here we have clicked on the Primary Element Wall finishes within the Group Element Finishes Internal. This screen reveals all 3 of its Primary Elements. The 100% figure against each indicates that each Element is fully present across the whole of the GIA. This would normally be the case unless all or part of the building was left in a completely unfinished state in which case the percent would be different ;or the user may change it – BUT NOT HERE. Otherwise, to delve further and adjust the quantities and basic resource drivers currently impacting on Wall finishes click on Wall finishes.

51 Reviewing /adjusting the extent of the Element This screen confirms that the Wall Finishes Element has been selected and applies to the whole of the building. In Copy and Edit mode you can amend these assumptions on this screen. If you want to see how the actual quantity has been calculated you must access the Element Folder…….

52 Opening the Primary Element folder This screen tells you that the Wall Finishes Element has been selected as one of the Primary Elements in the Group Element Finishes Internal and applies to the whole of the building. To see how the quantity of I has been calculated you must access the Element Folder by clicking on its title……….

53 Adjustments to be made at the Primary Element level Normally the only adjustment to be made here will be to the quantity of the Primary Element; the other options in the Navigation Pane here are for use when users want to take a broadbrush overview of the impact of changes in assumptions for these topics across the whole element. The Primary Element is where the basic factors affecting the quantities of every component in the element are displayed and may be adjusted. To delve further click on Element EQF Adjustment

54 Reviewing/adjusting the Primary Element quantities Many of the quantities adopted in the Default survey stem directly from the information included at the General Data Entry page; others come from quantity factors built into the survey based on typical designs for that type of building. Here we are about to enter the Wall finishes Element; note that it is in green as it has been selected to view and Maintenance Assessment is in brown as it has already been inspected. Note also that this menu is available at every level in the Elemental hierarchy so you can adjust Default or edited quantity assumptions at any level.

55 Reviewing the Element Quantity Factor (EQF) The Element Quantity Factor is the ratio of the area of the element to the GIA. The factors used by the program to calculate the quantity of Wall finishes are displayed here. The EQFs of the External Walls and the Internal Divisions are copied down from the calculations for those elements. In this prototype version you cannot adjust those other EQFs here – you have to go back into their folders to do so. However, in Version 1 this will happen automatically

56 View selection of Sub-elements The Wall Finishes Element (unusually) does not have separate Sub-elements so the title carries through to that level in the hierarchy. The Wall Finishes Sub-element has been selected at 100% which means that it is present in its entirety to fulfil its function within the building. You cannot adjust either of the percentages on this screen. To do so, or to make other fundamental adjustments to current assumptions in this Primary Element, you need to open up the Wall finishes folder as shown above; or you may start amending at Sub- element level by clicking on Wall finishes.

57 View selection of sub-elements The quickest way to explore the Sub-elements is to use the filter on the Primary Elements column. However, you may, if you wish, simply filter down and find the Primary Element you wish to explore or run down the list of Sub-elements (as here) until you spot the one you want. You may then open up the Sub-element folders by clicking on the appropriate heading.

58 The Wall Finishes Sub-element Using the Sub-element filter you may now click on the link to Wall finishes Sub-element to find out what has been pre-selected and the quantities thereof. The 100% pre- selected for the Wall finishes Sub-element means that it applies to the whole of the GIA in the currently viewed survey. It would be unusual for it to be otherwise but once the percentage has been selected the area of finished wall is generated by the program. How the program knows the quantities was explained earlier.

59 Reviewing and adjusting the quantities By clicking on the Wall Finishes Sub-element you can access the part of the model where the original quantity selections were made. You could see from the previous screen that 100% had been selected and when you are in the Copy and Edit mode you have the opportunity to change the preselected assumptions to fit your own requirements. You probably will not want to alter this one though.

60 Reviewing the Systems - Wall Finishes Within the Sub-element Wall finishes there are 2 Systems – Wall base applied and Wall finish applied. They have both been selected at 100% which means that each system applies to the whole of the area of Wall finishes calculated for that element. Again although you can see the Selected Percentages of each of these Systems you have to go into the System folders to alter them. Also, at this stage you can review and adjust the actual components included in the Systems.

61 Adjusting the Systems quantities This is the part of the model where the default System quantities were pre-selected. You have the opportunity to adjust these in the Copy & Edit mode. Again you probably will not want to alter these assumptions but other Systems may well be the subject of deletion or change of scope.No further adjustment of the quantities is available or needed at this point in the elemental hierarchy.

62 Reviewing the Wall finish applied System You can now find out what was in the Wall Finishes by way of Wall finish applied. Clicking on Components tab a filter drops out of the Systems heading allowing you quickly to select the System you want to review. This opens up the engine room of the CombiCycle program where all the built-in features affecting the whole-life cost and sustainability result may be explored and adjusted by the user as required.

63 View the type and quantities of the components In this survey the pre-selection is for 90% of the Wall finishes applied System to be Decoration only and 10% to be Ceramic tiles. The program has already calculated the area of the Wall finish applied System so this apportionment has applied quantities to each type of finish. The prototype model has an adequate menu of the more common types of building components but is a long way from being exhaustive - further specification options will be available in forthcoming versions of CombiCycle.. Again, these quantities cannot be altered on this screen so you must click on one of the headings…

64 Accessing the specification and performance data By simply clicking on any of the components in the Wall finish applied System - e.g. Ceramic Tiles as shown here – you can open up the Components Selection screen. This is where the Systems are analysed into the quantity to be allocated to each component and from where you can open up the Specification Adjustments folder.

65 Adjusting the applied finishes and their quantities Again, you have seen the quantities selected for the current survey but by clicking on the System you open up the Component Selection screen and can start to develop your own bespoke Wall finishes applied System. Note that the total may neither exceed nor be less than100%. Any areas not having applied finish will have been omitted by the percentage of the Wall finishes Sub-element ascribed to Wall finish applied in the previous stage of analysis. You will be barred from exiting until this is correct. Next you can open up any folder to review and adjust the performance characteristics.

66 The Specification Adjustments folder – ceramic tiles To see what sort of Ceramic tiles have been pre-selected and their performance characteristics you just need to click on Ceramic Tiles in the Wall finish applied Systems menu. This opens up details of all the key assumptions built into CombiCycle and allows the user to adjust any of them as required

67 The Specification Adjustments folder Having opened up the Component folder for Ceramic Tiles you will find a menu of 9 topics for you to explore under the title Adjustment Navigation. If you open up the text under …read more… you will find out more about this folder.

68 The default component unit rate The first section shows the price per sq.m. used in the program for the component – in this case the Ceramic Tiles. This is the base rate adjusted to reflect all the bespoke conditions you set on the General Data Entry screen e.g. quality, location, date etc. Professional cost consultants may wish to alter this rate for reasons of their own but have to leave behind a valid explanation as to why.

69 Viewing the selected performance factors The pre-selected thickness may be varied; this will change the price and any environmental factors depending on the weight of the material. The Functional Performance and all the other factors in this section are pre-set by the overall Performance level you chose on the GDE screen. Each may be changed here by selecting an alternative level from its drop-down menu. Many of these factors interact within the program e.g maintenance and manufacturing regime. More of this later.

70 Life-cycle replacement – CombiCycles risk analysis sub-program For each major component: a default life is set based on the conventional wisdom a schedule of generic risks to life-expectancy (e.g. poor installation, inadequate maintenance, exposure to elements etc.) The user assesses the level of exposure to each risk (based on design and operating decisions taken) the default life is replaced with CombiCycles calculated life

71 Viewing the life-cycle assumptions One of the many unique features of CombiCycle is the intelligent assessment of the likely life- expectancy of components; this is based on the risks to which they are exposed and the risk- containment strategies adopted by the developer. The typical life expectancy is built into the program as average but the Risk Analysis Factors on this screen may be assessed on an ad hoc basis and will affect the outturn. You may either accept the programs calculations or put your own prediction in – but you must say why you have chosen to overrule the programs predictions…….

72 Justifying a bespoke selection …..the reason why you are required to state your reasons for overriding CombiCycles set values is that some users may be tempted to alter the results to suit their own agenda. They may have very good reason to do so but their reason will remain attached to the component and will be shown in the Report of the survey (available in the next version of CombiCycle ).

73 Allowing for buildability Buildability is a term describing the effect of the design on the ease or otherwise of constructing the building. The prototype version of CombiCycle does not have the facility to adjust the capex for this factor but it will be built into future versions at a high level at first and later on an analysed basis. It has particular relevance to off-site fabrication.

74 Sustainability Assessment – Interim Measures Research by Ph D. students from Uni. of Lagos Components grouped according to typical production characteristics – e.g. natural timber, rigid tiles, upvc Environmental impact scored specifically for each component Weighted scores for each component multiplied by the quantity of each component and brought back to a score out of 10 This gives both the sustainability rating of the component and its significance in the building in quantitative terms.

75 Sustainability Assessment – Interim Measures: CombiCycle benefits Against each of these factors: Components and systems scored, weighted and quantified for sustainability risk pre-design. Cost v sustainability sensitivity carried out in detail pre- design Process repeated continuously throughout design development

76 Sustainability ratings- impact matrix The factors affecting the environment (green highlight) are taken from the Green Guide to Specification (BRE) and are weighted one against the other in terms of their perceived impact on the environment. The materials on the list have been scored by our team of researchers from University of Lagos, Nigeria. This first phase of research has been restricted to analysis of the generic building materials; phase 2 will extend to more detailed consideration of the manufacturing processes of all materials.

77 Reviewing the sustainability scores Researchers from the University of Lagos, Nigeria, have made a preliminary assessment of the impact of the generic processes involved in extraction/ manufacturing of each component on each of the environmental risk factors identified in Green Guide to Specification (BRE). Scores have been made against each factor for each component. The factors are weighted according to their perceived importance and the weighted scores give a Rating out of 10 for each component and the whole the building. Weighted scored Ratings may be reviewed at each level in the hierarchy so you can see where any problems are lurking. Again, users may override the scores but must state their reasons.

78 Adjusting the facilities services As explained earlier this prototype version of CombiCycle sets the cost and performance levels to follow the capex assumptions on the General Data Entry page; they can of course be altered in the performance section of this folder (see above) but Version 1 of the program will allow the facilities services data to be set and adjusted independently and altered in these dedicated sections.

79 Save and Return to Answers When you have finished exploring/adjusting the component attributes you click on Return to Answers to continue this process at will. You may also explore how the basic quantities for each element have been derived …….

80 Reviewing the Internal partition walls Sub-element The Primary Element Internal partition walls has 3 Sub-elements selected. The Primary Element quantity included in the Default survey (or a later adjustment by the user) is apportioned on the Primary Element

81 Adjusting the Element Quantity Factor (EQF)- Internal Divisions The authors of the Default survey had included an EQF of 0.6 which means that the area of this Primary Element is 60% of GIA. If you wish to amend this ratio you do so in the bespoke box – 0.8 has been included here. Once you Save and Close this will recalculate and the new EQF will be applied to the GIA. This results in a new quantity for the Internal Divisions Primary Element of 1372 sq.m. which will show when you open it up again. The Results change to suit this adjustment and quantities of other Primary Elements depending on this quantity (like the Wall Finishes) will also be revised and their Results varied..

82 Reviewing the quantitative calculations – External walls The quantities for the External walls Primary Element are based on the data provided by the user in the Physical Dimensions section of the GDE page. You can see that the survey incorporates the whole of the Element and if you want to see the actual quantity involved you just click on the heading and the Adjustmets screen will open up for you.

83 Elemental Quantity calculation/adjustment In this Default survey the External enclosure has been calculated by the program from the information you included in the Physical Dimensions section of the General Data Entry page. However the proportion which is External Apertures (doors and windows) has been assessed by the authors of the Default survey and is also revealed here. Again, you may change the External Enclosure but have to give a valid reason. The External Apertures percentage is not generated by the program so you can alter that at will. The new quantities replaces the current areas of both the Walls and the Apertures.

84 Helptexts Extensive Helptexts are being written to cover all component selection criteria In the case of the building services (a black art to many developers and consultants alike) full descriptions of the systems available and how they work will be included from the text of Whole-life Economics of Building Services by Bernard Williams and Malcolm Lay. These will be introduce in Version 1 commercial release.

87 Results of Sensitivity Testing of life-expectancy of components Sensitivity – Default : £93m Sensitivity A – 30% worse than expected : £153m Sensitivity B – 30% better than expected: £13m N.B. Costs do not change – but when they occur does

88 Early CombiCycle appraisal - £1/2 bn feasibility study in 13 different building types

89 Unique Features of CombiCycle Incorporates all key resource use, cost and sustainability drivers such as : date location performance processes management occupancy use climate orientation etc. etc.

90 Unique Features of CombiCycle Allocates system-specific cost drivers to components E.g. Boilers : adjust size or quantity performance specification energy-efficiency rating manufactured specification maintenance regime component life – default and risk life-cycle drivers heating load etc.

91 Gives effect to all quantitative impacts of building design Structural elements : all element/GIA ratios calculated from Data Entry Finishes elements : all element/GIA ratios pre-set with Helptext to assist in modification as required (see Element Folders) Services elements : all geared to GIA following cost curves for system components as researched in depth by the authors

92 Gives effect to resource-use curves per m²GIA for all building services

93 Building Services There is extensive coverage of the normal range of building services installations which are dealt with at the same hierarchical level of detail as the fabric components. Here the selection of the available Space heating and Air-conditioning Systems is shown; choices of components within these Systems is made in detail and amendable in the various hierarchical folders as for the fabric elements.
