Metrics Bar

back to top
Displays the high level metrics for your project.

 

PREDICTED 

The PREDICTED EUI value units are kBtu/sf/yr. The value displayed is based on the "Define Baseline" approach and the value displayed based on selections or entered in Section 3. Baseline & Target Energy Use Intensity.  If the "Status of Energy Model" is "Will NOT Be Modeled" or "Will Be Modeled", but a EUI has NOT been established, then "Not Determined" will be displayed.  If the "Status of Energy Model" is any other option the value displayed will be the EUI entered in PREDICTED field in Section 3. 

BASELINE 

The BASELINE EUI value units are  kBtu/sf/yr. The value displayed is based on the "Define Baseline" approach used for the project in Section 3 - Baseline & Target Energy Use Intensity.  The calculated or manually entered value in the BASELINE input field is what is displayed here.

GOAL

The GOAL EUI value units are kBtu/sf/yr. It is automatically generated once a BASELINE has been determined.  The formula is BASELINE X CHALLENGE (the current Architecture 2030 Challenge %).

SAVINGS 

The energy savings % for the project, which is either calculated by (BASELINE EUI - PREDICTED EUI) / BASELINE EUI or if the "Energy Model Status" is "Will NOT Be Modeled" or "Will Be Modeled", but a EUI has NOT been established, then "CODE EQUIVALENT" is displayed, and the percentage displayed is based on the "Design Energy Code" (Section 2) selected. 

CHALLENGE

Displays the Architecture 2030 Challenge table of the percentage reduction values for each of the milestone years to NET ZERO in 2030. The current percentage reduction level is highlighted for the current reporting year, which the value used to determine the value displayed in GOAL.

 

Input Screens - Common Inputs
back to top

The input fields displayed vary based on the Project Category that is selected for the project.  General Inputs: Section 1 contains the same common input fields, while the other sections on this screen and the optional detailed input screens will have different input fields
 

Section 1: Input Building Specifications 

  • Project Name* - 

    Associate a name with your project.  By default the input field is blank.

  • Project ID* - 

    A required field. Provides the unique identifier for the project.  A default Project ID is assigne when a project is created, but you can change it by directly entering a new value into the input field.

  • Project Category* - 

    The category designation for the project that determines the input fields displayed and the minimum input requirements for the AIA 2030 Commitment. The three AIA 2030 Commitment category types are: 
      -  Non-Residential (Non-Res) 
      -  Residential (Res) 
      -  Interior Only (IO)

  • Construction Type

    The construction type field, which is a required field, enables the AIA 2030 DDx to effectively capture if the project is “New Construction” or a “Major Renovation of Existing Building”.  The field is required to be completed for all Project Category types.  A default value is not provided, so one of the two options is required to be selected before a project can be saved. 

    The construction type field is also included in the DDx API and Batch Import.

    Country* - 

    The Country where the project is located. If a country other than the United States, Canada, China or India is selected, then the State/Province field is not displayed.  For projects in other countries, see International Guidance section.

  • State/Province* - 

    The state or province where the project is located.  The field is displayed if the Country selected is the United States, Canada, China or India.  The drop-down list will also vary based on the country selected.  If any other country is selected this field will not be displayed. 

  • Zip/Postal Code* - 

    The 5-digit zip code where the project is located, if in the US.  International zip codes that are number based can be entered as well.

    City* - The city where the project is located.  For countries where the State/Province field is not available (all except for the United States, Canada, China and India), the city is a required field.

    Year of Occupancy* - 

    The assumed year the project is to be occupied.

    Climate Zone - The United States ASHRAE climate zone set provide the drop-down list selections.  A climate zone is automatically associated with a project when a recognized zip code is entered for a US or Canadian location.  The automatic selection can be changed by selecting another climate zone for the project.   

    ASHRAE Climate Zone Map for United States

    Reporting Year - The 2030 Commitment Reporting Year associated with the project.  When a new project is created the default value is the current reporting year.  The current AIA 2030 Commitment Reporting Year schedule is from April 1st to March 31st the following calendar year.   

    Office Location - The Office Location that is running the project for the firm.  By default the primary (headquarters) office for the firm will be the default selection, but it can be changed by selecting an alternative office from the drop-down list.  Each firm account is required to have one Office Location associated with it, and if the firm only has one office location that is the only one that will be displayed.  The Office Locations can be edited, added or deleted in Section 5 on the > My Account screen.  

    Project Phase* - The current design phase for the project.  Projects can have one, multiple or all phases saved for a project.  Each project phase will appear as a separate row on the Portfolio screen, but they will be grouped together.  The design phase options include (phase abbreviations that will appear in Project View drop down):

    -  Concept (CC)
    -  Schematic Design (SD)
    -  Design Development (DD)
    -  Construction Documentation (CD)
    -  Construction Administration (CA)
    -  Design Closeout Final (Final)* - the final design record when a project has been completed.  
    -  On-hold - selected when the project has been put on-hold.

    Design Closeout Final

    An important and critical project phase for each project!  It establishes a design performance reference point for each project that can enable comparisons, such as:
    -  Comparing the performance of the design phases
    -  Comparing the project to other projects
    -  Comparing design performance to actual performance data  (when actual performance data can be associated with projects in the AIA 2030 DDx)

    The Design Closeout Final project phase will be the reference point for all of these comparisons!  

    Benefits the overall AIA 2030 DDx dataset

  • By creating and submitting a Design Closeout Final phase for each project, the DDx can track additional metrics that can be useful to all signatory firms, such as the number of completed projects each reporting cycle, the GSF of completed projects, the project category and the project use types as well 
     

    PORTFOLIO Tracking
    Based on the importance of the Design Closeout Final phase, the AIA 2030 DDx allows firms to track if a design closeout final stage for a project has been submitted or not.  In the project table on PORTFOLIO is a column called “Final”.  This column tracks if a “Design Closeout Final” phase has been submitted for a project or not, so that you can see which projects need to be addressed.  An orange dot appears on the rows for project phases that do not have a “Project Phase = Design Closeout Final” AND “Reporting Status = Submitted”.   

    Once a project with a Design Closeout Final stage is submitted, then the orange dots for all of the project phase rows for that project will disappear.  One thing to note, if you see an orange dot in the “Final” column for a project that has a Design Closeout Final phase created, it is being displayed because the project is “In Progress”, and has not been “Submitted”. 

    When and How to Use
    Use scenarios for the Design Closeout Final phase

Use Types Input Fields and Table
 

  • Use Types Table
  • This is where the Use Types for the project are setup and can be edited, which influence the input fields displayed in other areas within DDx. The portion of the table on the right (see example below) is auto-generated and is intended to provide you some initial feedback on what the BASELINE EUI and LPD will be for the Use Types and the areas associated with them for the project. Note: They do not determine the baseline values associated with the project. That is done in Section 2. Establish Design Target and Baseline. Although it should also be mentioned that if you select the National Average baseline option, the values will be the same.

  • Use Type* 
    Note: Each project is required to have at least one Use Type

    The main program areas in the project. There can be multiple use types associated with a project to effectively capture mixed use projects, but at a minimum there has to be one. If there is only one use type, it will be the same as the overall building use type. Although there can be more than one, they are required to be stacked on top of each other and one floor cannot contain multiple use types. The source of the dropdown list is the list of building types that were included in the previous AIA 2030 Commitment spreadsheet tool. Multiple use types cannot only be effective in assisting to shape a more relevant Baseline EUI target, but if the project is exported to DOE's Building Asset Score, it can create a more refined EnergyPlus model and resulting analysis.

  • Area* 
    Units = ft2

    The overall area for each use type in the project.

  • ADD Use Type

    Selecting the "+" icon will add a new row for a new use type to the table.

  • DELETE Use Type

    Only appears when there is more than one use type displayed. Selecting the "x" icon deletes the use type in that row.

  • BASELINE (National Average) 
    Units = kBtu/sf/yr

    An auto-generated value determined by the Use Type selected, which is "looked up" in the use type table to determine the BASELINE CBECS Average value displayed.

  • GOAL (2030 Challenge) 
    Units = kBtu/sf/yr

    An auto-generated value determined by multiplying the BASELINE CBECS Average by the Architecture 2030 Challenge percentage reduction target (60% for 2014)

  • Lighting Power Density BASELINE 
    Units = W/sf (Watts per square foot)

    An auto-generated value determined by the Use Type selected, which is "looked up" in the use type table to determine the BASELINE Lighting Power Density (based on ASHRAE 90.1-2007 values) value displayed.

  • Lighting Power Density GOAL 
    Units = W/sf (Watts per square foot)

    An auto-generated value determined by multiplying the BASELINE LPD by the AIA 2030 Commitment percentage reduction target (25% for 2014)

  • Weighted Totals

    The auto-generated totals that are influenced by the use types and the areas associated with them. An example is provided in the figure below. In this example the Retail use type accounts for 22% of the overall building area (50,000/225,000) and the Office use type accounts for 78% (175,000/225,000). The weighted total in the BASELINE CBECS Average column is therefore determined by multiplying the Retail BASELINE EUI (72) by 22%, then multiplying the Office BASELINE EUI (104) by 78%, and then adding them together. The same calculation is performed for each of the four columns.


    Section 2: Energy Analysis

    Status of Energy Model*


    PREDICTED
    Active for direct input of the Predicted EUI.  If it remains unchecked, "Not Determined" is displayed in PREDICTED, and the field cannot be edited.


    Will NOT be modeled
    All the Energy Model inputs are hidden, and PREDICTED displays "Not Determined".


  • Determines if the project has an energy model developed or not, and what input fields in Section 2 and Section 3 are displayed.  The selection options include: 

    HAS BEEN Modeled
    All Energy Model input fields and the link to the Design Energy and Emission Inputs dialog box are displayed.  In addition PREDICTED (Section 3) is active for direct input of the Predicted EUI.

    Will be modeled
    The inputs for "Responsible Party for Energy Model" and "Energy Modeling Tool" are displayed.  In addition a checkbox question appears in Section 3 below BASELINE, GOAL and PREDICTED, asking if an EUI has been established yet?  If so, and the checkbox is selected, then 

  • Responsible Party for Energy  Model 
    Note: Displayed when "Status of Energy Model" is "HAS Been Modeled" or "Will Be Modeled". 

     

    Identifies what party is doing the modeling for the project.
    Options: : Architectural Team, Design Engineer, Modeling Consultant, Other 

  • Energy Modeling Tool 
    The field is displayed when "Status of Energy Model" is "HAS Been Modeled" or "Will Be Modeled", and it is a required field.  It documents the analysis tool that was used for energy modeling/analysis during the specific project phase.  The energy modeling tool may vary across the separate phases of the project.  The list of options is not comprehensive, but is intended to be updated periodically to provide a set of common and relevant tools in the industry.   

    The field is also a filter on RESEARCH, allowing the DDx project database to be queried for a single or set of energy modeling tools.

     

  • Time spent on Energy Modeling 
    Note: Option only available when HAS BEEN Modeled is selected for the "Status of the Energy Model"
     

    The estimated range of hours spent by the responsible energy modeling party on developing, refining and analyzing the energy model. If your firm did not create the energy model, and it is challenging to obtain the information, estimate the amount of effort for this reporting cycle
    Options: 0-20, 20-40, 40-120, 120-300, 300+ .

     

  • Design Energy and Emissions Inputs 
    Note: Option only available when HAS BEEN Modeled is selected for the "Status of the Energy Model"

    Selecting the checkbox launches a dialog box that allows you to enter the the relevant values for some or all of the input fields to determine the Design SIte Energy Use Intensity, Design Source Energy Use Intensity, the Design Greenhouse Gas Emissions and the Design Greenhouse Gas Emissions Intensity.  Once the relevant input values have been entered, select the "Calculate" button and the metrics will be calculated based on the values. to develop the auto-generated metric values displayed at the top of the dialog box.  

    Design Energy and Emissions Dialog Box

  • The input fields are to determine the fuel sources utilized on the project, which can range from eletricity to steam to diesel to on-site renewables. Note the units for electricity (kWh/yr) and Natural Gas (Therms/yr) differ from the other fuel source units (MBTU/yr).

    Zip Codes and eGRID - The caclulations are based factors on the project zip code entered, which is matched to electricity emissions factors obtained from the current versions of the US EPA's Power Profiler eGRID Subregion and the GHG Emissions Finder Tool.  



    Design Energy Code
    A required field that documents the design energy code for the project.  The drop-down list contains a periodically updated set of design energy codes, but is not comprehensive. 

    If the project's "Energy Model Status" is either of the following options, then the PREDICTED field will not be active, and display “Not Determined”.  The Design Energy Code selected determines the code equivalent savings associated with the project, which is displayed at the top in the SAVINGS section of the metrics bar. To review a table of the current design energy code selection options, and their associated code equivalent % savings assumptions, see
    Input: Code Equivalent.

    Energy Model Status options that utilize Design Energy Code equivalent savings:
      1)  "Will NOT be Modeled"
      2)  "Will be Modeled", with the "Has the project established an EUI yet?" checkbox remaining unchecked (see figure)


  • What to do if design energy code is not on the list? - If the design energy code for the project is not included on the list, please refer to the Code Equivalent, review the code options, and select the one that is the most appropriate.  Also, please select the Feedback button on the DDx, and input information similar to the information displayed in the figure below,to let AIA know of design energy codes that should be considered for inclusion.



    Will Energy Use Data be Collected?
  • A checkbox input that establishes if energy use data will be collected for the project. An important component of successfully bringing a building on-line effectively and tracking performance moving forward.


Varying Input Fields
 

For each of the three possible project categories (Non-Residential, Residential and Interior Only), General Inputs: Section 1: Input Building Specifications are all the same input fields.  The input fields start to differ at Section 3, as well as for the optional added detail screens.  The table below provides links to the main sections for Non-Residential and Residential, and Interior Only are included in a separate section.

Section: Baseline & Target Energy Use Intensity

The first step is to select the "Define Baseline" approach, which establishes the BASELINE and GOAL EUIs.  Next the PREDICTED EUI can be entered for modeled projects, and not modeled projects will display "Not Determined".  Once Section 2 and 3 are completed the key metrics (displayed at the top of the screen) are effectively defined.  



 

  • Define Baseline 


    You will need to select one of three options (radio buttons) for how the BASELINE EUI will be determined for the project.  It will either be through calculation, natural average based on building type or your direct entry. The BASELINE EUI is displayed in this section as well as in the Metrics Bar at the top of the screen. 


    Note: An energy model baseline value (ASHRAE 90.1 Appendix G compliant or other) could also be entered in the "Other" field.

  • Option 1: Zero Tool

    Selecting this option uses the Zero Tool to incorporate regional weather files to determine a baseline based on 2003 CBECS. Use default values or click to the "opional inputs" button to provide additional information.  If using the optional inputs pop-up to calculate, each use type must be completed (with the exception of the optional Annual Heathing and Cooling Degree Days). By completing the inputs and selecting > Calculate, the Zero Tool API is utilized to calculate the Zero Tool EUI. The result populates the BASELINE field in section 3, and is displayed in the metrics bar at the top of the screen.

    Option 2: National Average (CBECS)

  • This option simply looks up the 2003 CBECS Averge (Commercial Building Energy Consumption Survey)that corresponds to the use type selected in section 1.  See help section National Average for the table of use types and National Average EUIs.  If more than one use type has been selected for a project, a weighted total calculation is done to develop the National Average EUI for the project.

     ((Use Type 1 EUI X Use Type 1 GSF) +  
    (Use Type 2 EUI X Use Type 2 GSF)) / (Use Type 1 GSF + Use Type 2 GSF)
     

  • Option 3: Other

    This option is provided for project types and cases that don't lend themselves to effectively using Option 1 or Option 2. Also if a detailed baseline energy model has been developed for the project in alignment with ASHRAE 90.1 Appendix G, then you can input the EUI manually in the BASELINE Input field.

  •  
  • Predicted EUI 
    Units = kBtu/sf/yr

    The current design energy use intensity (EUI) for the project. Typically the manually entered design EUI will be the result of an energy model simulation and/or a parametric simulation assessment. The value entered here will be designed on the Metrics Bar in the DESIGN area.

  • BASELINE 
    Units = kBtu/sf/yr

    The EUI value that is determined by the option selected in BASELINE TARGET to develop the BASELINE.

  • GOAL 
    Units = kBtu/sf/yr

    Once the Baseline EUI has been established, then the GOAL EUI is displayed for a quick reference. The calculation is just the BASELINE EUI multiplied by the current Architecture 2030 Challenge % reduction. The GOAL EUI is also displayed in the metrics bar.

    Define Baseline approach using Target Finder for a project that has not been modeled

Section: Additional Inputs

  • Lighting Power Density (LPD) for whole-building/addition projects 
  • Units: Watts/Square Foot (W/sf)

    The lighting power density for your overall building as compared to the overall square footage of the building. Provides a useful comparison metrics for your projects, as well as energy use indicator

  • Occupancy Sensors Included?

    A checkbox input that establishes if occupancy sensors were used on the project.

  • Daylighting Sensors Included?

    A checkbox input that establishes if daylighting sensors for daylight dimming controls were used on the project.

  • Window-to-Wall Ratio % 
    Input Type/ units: Manual Input/ % (percentage)

    The window to wall ratio is the percentage of glazing per wall area for all sides and all floors of the building. Provides an interesting comparison metric for firms for their projects and portfolio, and also provides a useful energy use indicator.

  • Reduction in Potable Water per LEED?

    A checkbox input that establishes if reducing potable water, along the lines of the requirements in the LEED for Building and Construction Rating system, was pursued as a strategy for the project. Why flush potable water?

  • Only non-potable water used for irrigation (or no irrigation)?

    A checkbox input that establishes if a strategy for the project was to use only non-potable water for irrigation or to include no irrigation. Why spray potable water on a lawn?

  • Water collected for reuse (eg. Rainwater, graywater or blackwater)?

    A checkbox input that establishes if water harvesting of various types was a strategy for the project? Why not use the rainwater for the first time or other types of water again?

  • Renewables

    Establishes if renewable energy sources are an energy savings strategy and part of the project.  Select all that apply.  The current options are PV (Photovoltaic), Wind Turbine, Solar Thermal, and none. 

  • ASHRAE 90.1 Appendix G Baseline Energy Model 
    Input Type/ units: Manual Input/ kBtu/sf/yr

    You can associate an additional Baseline EUI value from an ASHRAE 90.1 Appendix G model with your project for reference, if you have determined the Baseline EUI for your project using another approach.  If you are interested in using the result from an ASHRAE 90.1 Appendix G model for your project, you can enter the BASELINE EUI in Section 2 using the User Defined approach.  Note:  the entry of a value here is only for reference and comparison, and does not influence any calculations within the AIA 2030 DDx.  

  • Section: Inputs Responsibility

    A user for the firm can be associated with the project, which could be used for internal coordination to identify who is responsible for completing the project inputs, review, submission or other.  The options on the drop down list displayed are the users that are associated with the firm's account.

Non-Residential: Building Envelope

A workspace that is influenced by the use types created on General Inputs for the project. This area of the workspace is configured as an accordion, so that the Building and Envelope inputs for each Use Type can be contracted or contracted depending on the active Use Type. Each use type for the project will have "Building" and "Envelope" tabs that will allow you to define different types for your project.


Use Type Name
The use type name will display in the tab above section 1.  A tab will be displayed for each use type that is a part of the project.

1. Building
Defines the building shape, orientation, zone configuration and operating hours for each use type

  •  
  • Footprint Shape

    Options: Rectangle, L-shape, H-shape, T-shape, U-shape 
    To create the basic geometry for the building, select the desired shape from the available icons displayed with the diagram. Each diagram has A, B, C, D Defines the shape of the building footprint for the use type. The shape selection and definition identifies the basic geometry for the project energy asset model that is created, and informs the amount of building envelope area for the project

  • Bounding Box Width

    Units: Feet (ft) 
    The overall width of the project if you were to lay a box over the top of the footprint shape.
     

  • Bounding Box Length


    Units: Feet (ft) 
    The overall length of the project if you were to lay a box over the top of the footprint shape.

  • Area


    A field reporting the area of the use type entered in General Inputs. It is for reference only and not editable.

  • Starts on Floor


    The number of floors associated with the use type. The order of the use types is important, because it determines how the model is constructed from the ground up. The first use type starts the count.


    Example 1: If the first use type was three floors, all above ground, then the second use type would start on floor 4. 
    Example 2: If the first use type was three floors, with one floor below ground, then the second use type would start on floor 3.

  • Number of Building Stories ABOVE ground


    The number of stories of the project that are above the ground plane. To minimize inputs a single input value is provided for ABOVE ground stories, so you will have to use your discretion on the number of stories to include if partial floors. 

  • Number of Building Stories BELOW ground


    The number of stories of the project that are above the ground plane. To minimize inputs a single input value is provided for BELOW ground stories, so you will have to use your discretion on the number of stories to include if partial floors. 

  • Occupants

    Establishes the overall occupancy number for the use type..


  • Orientation (degrees from North)

    Units: Degrees (from north); default = 0 
    You can enter 0 to 360 degrees in the input field on the lower left of the building shape diagram to set the orientation for your project. 0 = North, 180 = South. This also establishes the orientation and the starting point for the building block shape that is created using the width, length and building footprint shape. 
    Notes: the resulting form will most likely not be an exact representation of the project. The intent is that it will provide a representation that is ‘close enough’ to still be very useful.

  • Floor to Floor Height 

    Units: Feet (ft) 
    The typical floor to floor height for the floors associated with this use type. Although projects can potentially have varying floor to floor heights, you should input the floor to floor height that is most typical for the project.

  • Floor to Ceiling Height 


    Units: Feet (ft) 
    The typical ceiling height for the floors associated with this use type. Although projects can potentially have varying floor to floor heights, you should input the floor to floor height that is most typical for the project.

Operating Hours and Occupancy %

  • Open and Close Times


    By selecting the check box for any or all of the three options (Weekdays, Saturdays and Sundays), it activates the row and you can select the operational time of Open and Close from the drop down lists.

  • Occupancy %


    In the same row as the operational times, you can enter a % of occupancy for that day, which sets the peak for the assumed occupancy schedule. The number of occupants assumed at each time = Number of occupants X occupancy %.

2. Envelope

  • Ground Floor Type

    Input Type: Choice 
    Options: concrete over un-conditioned space; Slab on grade; Steel joist; wood frame

    Establishes the type of ground floor construction that is predominately being used for the ground floor.  Information for intermediate floors on projects is not needed, so this input focuses solely on the ground floor.  This input helps establish the ground floor construction assembly as well as a default R-value, which is also based on the location and type of the building that have been input earlier. 

  • Floor R-Value
