GBC ScreenShots Calculator
About:

---

GBC ScreenShots:

• Some of the worksheets are to some degree stand-alone, but most are also interlinked within this one spreadsheet so decisions made on earlier worksheets feed into later worksheets to carryout calculations.
• Later worksheets require more information or decisions by the user to make use of the earlier decisions, in more calculations.
• One sheets “UToWattsToCO2” require few inputs by the user, it assembles and calculates most things for you, you only need to choose the fuel source.
• The user is required to assess the results and decide if they wish to reconsider earlier decisions and go back to adjust values and to instantaneously improve the overall results.

Welcome:

---

About:

• This page, is about the scope and ambitions of this Calculator

---

Development:

• Described what the calculator is about and how parts interact and future development

---

Instructions:

• 
• Line by line or cell by cell instructions to edit the worksheets to make them project specific

---

Revisions:

• Record of changes and levels of completion during development by GBE

---

Project revisions:

• Keep your own records of application in projects for audit trails

---

Schedule Accommodation:

• Whole Building’ and

Room by Room Schedule of Accommodation

• Users add sizes, hours of operation, design temperatures, inside and out
• It works out areas and volumes,
• ‘Room by room heat loss’ calculator to determine radiator or under floor heating requirements
• Or start with a boiler size and work out how much insulation is needed to ensure the boiler is enough

Form Factor:

• A quick analysis of the building form factor and set target U values to respond to them.
• To be added or developed:
• Correlation between form factor and insulation thicknesses
• Form Factor could be developed to adjust for dormers, bay windows, porches, conservatories, riel windows, colonnades, etc.

---

Building Elements Scope:

---

Building Element Area Calculations

• List of 29 building elements and 12 secondary-elements and their areas
• The user identifies which are included in their project design and any of their respective dimensions and areas missing from the schedule of accommodation
• To accommodate a multitude of secondary element sizes an additional schedule is included

---

U values Etc.: 

• Comparisons between Building Regulations (E, W, S, NI and others), Energy Standards, FEES, AECB carbonLite, Passivhaus, EnerPHit, EAMs, etc.
• Including: U values, Airtightness, Form factors, Primary Energy, etc.
• Allowing users to choose and apply chosen set of targets to projects.

---

Insulation: Material k to U Value Thicknesses

Wide view:

Close up:

• Lists of insulation materials organised by material groups with best average and worst k values
• Applying the chosen U values this provides an instant comparison of materials and thicknesses
• To be developed:
• more materials and more k values

---

Insulation: Materials to Decrement Delay

• Includes the first stages of development of the Decrement Delay calculator (incomplete)

---

Legend & Terms:

• Legend of cell colour codes, cell fills and Schedule of terms and insulation materials to help understanding
• Not a functioning part of the calculator (incomplete)

---

Elements:  Assemblies of Components & U value

• Detailed descriptions of 24 of 29 potential elements and 12 secondary-elements making up the external envelop of a building and includes their functional components
• Allows the user to choose elements and assemble them by choosing their combination of functional components and then choosing the materials for each component.
• Where possible a default size is added and where necessary the user adds insulation and other component thicknesses.
• Using each materials k values and set resistances it calculates all of the R and U values automatically
• Costs of insulation and windows are added here to help persuade architects and clients to spend money on insulation and higher performance windows and glazing
• To be completed: 5 elements to be added

---

Elements: Bill of Materials Quantities Costs

• To allow Architects to cost plan their projects a Bill of materials, quantities, labour and costs is added based on building fabric only so far.
• To be added: Non-envelope items, Services

---

Resistances:

• Is an information resource for default surface and cavity resistivity’s;
• ‘Element’ obtains values from here

---

Conductivities:

• Is an information resource for materials and their properties for use in Components of ‘Elements’
• The user can copy information manually into Elements (Automated cell population to be implemented)
• Its is to be developed as a look up table to automatically populate Component of ‘Elements’

Products:

• Lists of Products with characteristics, intending to develop into a Look Up Table to populate ‘Elements”

---

Insulation Cost Thickness:

• Is an information resource for materials, their properties and costs for use in Components of ‘Elements’
• The user can obtain their own information or copy information manually
• Its is being developed as a look up table to automatically populate Component of ‘Elements’

---

Secondary Elements Costs:

• Is an information resource for secondary elements (Windows doors rooflights) and their properties for use in Components of ‘Elements’
• The user can obtain their own or copy information manually
• Its is to be developed as a look up table to automatically populate Component of ‘Elements’

---

Element Summery:

• Summarises 24 of 29 Elements and 12 Secondary Elements calculated U values,
• Compares with targeted U values, highlighting any shortfalls
• More elements to be added

---

UToWattsToCO2:

• Assembles elemental areas and U values to calculates energy losses from each element and total secondary elements to give total losses and each as a % of the whole so comparisons can be made by the user and gives a chance to reconsider earlier decisions
• Particularly useful is the comparison of basement, walls, roofs, floors and all glazing

---

FuelCarbonFactor:

• Is an information resource developed as a look up table used by ‘UToWattsToCO2’
• Needs up to date factors

---

Cost Per m2:

• This is a converter:
• If the information provided by Manufacturers/Suppliers is not in £/m2
• This will help with converting the information provided to the required format

---

Drop Down List:

• Used to populate cells with readymade answers to avoid typing, avoid errors and limit choices
• Lists can be added to, as long as the last two cells remain at bottom of sets

---

Supplier Request Form:

• Used to request information on products from manufacturers or suppliers

---

Condensation Check:

• To be developed

---

EE EC SC Calculator:

• To be developed: Embodied Energy Embodied Carbon Sequestered Carbon calculator

---

Readymade Competent Elemental Assemblies

• To be developed: 892 Competent Elemental assemblies ready to use

---

User Feedback

• An opportunity for users to highlight any problems or opportunities for improvements

---

User Survey

• There are many planned stages of development, have we go the order right?
• What are your ambitions and priorities?
