The document describes D.I.E.G.O. TOOL, an Excel-based options appraisal tool that generates optimal energy strategies for buildings and developments. It assesses combinations of low and zero carbon technologies to advise on energy policies. The 5-step tool evaluates energy production, sizing, and emissions reductions for technologies. It provides quick, low-cost feasibility analyses to help clients evaluate projects and make "go/no-go" decisions earlier. The tool has been used successfully on many of the firm's projects.

3. Originality Why? What?

4. Originality Why D.I.E.G.O.Tool To advise developers on appropriate responses to the various energy policies under the climate change agenda To asses combination of L&ZC technologies and the effects of gradual tightening of policy against project phasing towards Zero Carbon To overcome the barriers to energy technology implementation at the preliminary feasibility stage. Originality

5. Originality What is D.I.E.G.O.Tool In summary the tool is: An options appraisal tool that generates best energy strategy for multiple buildings or multi-phased masterplans Designed to provide energy strategy before individual building designs have developed beyond accommodation schedules Typically deployed as part of outline planning stage Very well suited to phased developments Helps engineers understand scope, cross-sell services, and avoid scope-creep Originality

7. Reproducibility How Works?

8. The model was designed with standardisation and robustness in mind. A 5 step standard analysis procedure is used to evaluate the energy production, pre-sizing and carbon dioxide emission reductions for various types of proposed energy efficient and renewable energy technologies.

13. Value to MMG’s Business How helps? When helps? Where helps?

14. Energy project developers, investors, and financers continually grapple with questions like “How accurate are the estimates of carbon costs and energy savings in a EOA?” EOA faces with two conflicting requirements: Value to MMG’s Business How D.I.E.G.O.Tool helps Value to MMG’s Business Energy Option Appraisal EOA Keep the project development costs low in case funding cannot be secured, or in case the project proves to be uneconomic when compared with other energy options . Spend additional money and time on engineering to more clearly delineate potential project costs and to more precisely estimate the amount of energy produced or saved

15. The usual procedure for tackling this dilemma is to advance the project through several steps. At the completion of each step, a “go/no-go” decision is usually made by the project developer as to whether to proceed to the next step of the development process.

16. Each step of this process could represent an increase of one order of magnitude or so in expenditures and a halving of the uncertainty in the project cost-estimate Value to MMG’s Business How D.I.E.G.O.Tool helps Value to MMG’s Business

17. MMG’s ability to provide clients with high quality, low-cost pre-feasibility and feasibility studies is critical to helping them achieve cost and risk certainty, by “screening out” projects that do not make financial sense.

18. In this regard the D.I.E.G.O. Tool, which can be used to prepare both pre-feasibility and feasibility analysis, specifically addresses these issues by providing quick and valid results at low cost, on which “go/no-go” decisions can be made.

19. The Sustainability Masterplanning team have used the resulting tool in every sustainability masterplanning project on its books since the tool's creation. Use of the tool on the South Shields project for Turner and Townsend enabled the Sheffield project team to complete the energy strategy commission well within the budget. The tool was included in the Newcastle Science Central bid as one of our USP’s, and we subsequently won the next project phase over the incumbent engineers, Arup. The tool has contributed to the fact that we are one of the preferred consultants for the well known developer Crest Nicholson, from whom BFL had £600k of turnover since 2005.

21. CIBSE - currently being considered as the basis for an industry wide LZC technology toolkit Leading edge in the market – there are no proprietary tools on the market that even come close to the level of analysis made possible by the D.I.E.G.O. Tool. BIM - can be adopted as part of the integrated multidisciplinary technologies used to produce a BIM. In fact, it generates information such as the energy-carbon life cycle which represents one of the essential quantities encompassed by BIM.
