Version 5.3 Build 01

Athena Impact Estimator for Buildings 5.3.0111
- released September 2018
(hotfix for 5.3.0110 - September 2018)

  1. LEED v4 Whole Building LCA Credit Report: in the "LCA Software Inputs" section on page 5 had the following issues:
    • Building Height was always reported in "m" even when the reference project units system was Imperial and "ft" was expected
    • Gross Floor Area was always reported in "m2" even when the reference project units system was Imperial and "ft2" was expected
    • Bill of Materials Unit of Measure values were always being reported in terms of the reference project units system, even when the proposed building values were in SI

    To correct the above issues, all values are now converted to the units system of the reference building and the appropriate unit of measure has been added to the Building Height and Gross Floor Area value cells.

    This bug was introduced with the release of version 5.2.0116 in December 2016.

  1. Pre-Engineered Roof and Wall Assemblies were using the wrong Materials for Cladding. This bug was introduced with the release of version 5.3.0105 in July 2018. In particular:
    • 24 Ga. Metal Roof Cladding was replaced by "H.D.B"
    • 26 Ga. Metal Roof Cladding was replaced by "Granulated Blast-Furnace Slag" and was causing a divide by zero error to be thrown
    • 24 Ga. Metal Wall Cladding was replaced by "H.D.B.C."
    • 26 Ga. Metal Roof Cladding was replaced by "Cement"

(scheduled update)

In 2017, the Canadian Ready Mix Concrete Association, CRMCA, published an Industry Wide EPD. We have updated the database to include the CRMCA's 2017 EPD benchmark mixes.  We also added the other CRMCA 117 EPD mixes to the Bulk Product Projects folder under the File menu.  Details of the EPD mixes and how to use them in projects can be found in a PDF document that is available when you choose this option.

The benchmark mixes for each strength class in the EPD are included in the database and are available once the tool is installed.  Six benchmark mixes are available in the assembly dialog boxes for all concrete assemblies, and details are explained in the help file for each assembly.  The remaining benchmarks are available in Extra Basic Materials and can be used in the assemblies as user defined mixes (see the help files for instructions).

General Changes

  1. The 6 CRMCA benchmark mixes are now tied to the following assemblies. When a project location is a Canadian city, then choosing a particular concrete strength using the radio buttons in the assembly dialog boxes will use the CRMCA benchmark for that strength in the model, and if the project location is an American city, then the NRMCA benchmark will be used.
    • Columns & Beams
    • Composite Metal Floor
    • Concrete Hollow Core Floor
    • Concrete Parking Garage Floor
    • Concrete Precast Double T Floor
    • Concrete Suspended Slab Floor
    • Open Web Steel Joist Floor
    • Composite Metal Roof
    • Concrete Hollow Core Roof
    • Concrete Parking Garage Roof
    • Concrete Precast Double T Roof
    • Concrete Suspended Slab Roof
    • Open Web Steel Joist Roof
    • Concrete Footing Foundation
    • Concrete Slab on Grade Foundation
    • Cast in Place Wall
    • Concrete Tilt Up Wall
    • Insulated Concrete Form Wall

Database Changes

  1. New Material: Added Concrete Benchmark CAN 15 MPa to the database with mix information from the NRMCA Industry Wide EPD since the CRMCA’s EPD did not include a 15 MPa mix.
  2. New Material: Added Concrete Benchmark CAN 25 MPa to the database with mix information from the CRMCA Industry Wide EPD.
  3. New Material: Added Concrete Benchmark CAN 30 MPa to the database with mix information from the CRMCA Industry Wide EPD.
  4. New Material: Added Concrete Benchmark CAN 35 MPa to the database with mix information from the CRMCA Industry Wide EPD.
  5. New Material: Added Concrete Benchmark CAN 40 MPa to the database with mix information from the CRMCA Industry Wide EPD.
  6. New Material: Added Concrete Benchmark CAN 45 MPa to the database with mix information from the CRMCA Industry Wide EPD.
  7. New Material: Added Concrete Benchmark CAN 50 MPa to the database with mix information from the CRMCA Industry Wide EPD.
  8. New Material: Added Concrete Benchmark CAN 55 MPa to the database with mix information from the CRMCA Industry Wide EPD.
  9. New Material: Added Concrete Benchmark CAN 60 MPa to the database with mix information from the CRMCA Industry Wide EPD.

- released August 2018
(hotfix for 5.3.0105 - July 2018)

General Changes

  1. Concrete Block Wall: assembly should only support 200mm (8") concrete block thickness. Version 5.3.0105 introduced 100 mm (4"), 150 mm (6"), 200 mm (8"), 250 mm (10"), and 300 mm (12") concrete blocks, but we presently only have concrete block wall assembly rebar data for for the 200 mm (8") concrete block.

- released July 2018

General Changes

  1. Operating Energy was double converting energy quantities if Imperial units were specified in the Operating Energy form.
  2. Concrete Footing Foundation was updated. Rebar options were changed, width and thickness constraints were removed.
  3. Concrete Block Wall was updated. Rebar is now constrained to just #15M (#5), five new concrete block thicknesses are now available, and material calculations have been updated. New material Grout-Coarse is now use to fill hollow cavities and Mortar is now only used to joints.

Database Updates

  1. TRACI Measures: Updated TRACI measure characterization factors for Global Warming Potential and Acidification Potential. Methane and N20 factors for GWP and Ammonia and Sulphur Oxides factors for Acidification Potential were aligned with the current values used in LCA software. The EPA has not updated those TRACI factors, our software had been using values updated to more recent IPCC values, but our SimaPro LCA software is using the previous values, so we’ve reverted them back to be in line with those values.

    Even if material LCI data hasn’t changed, the GWP and Acidification results will change solely due to the changes in the characterization factors, and will depend on the material. For example, Portland Cement results are barely changed, decreasing 0.2% for both GPW and Acidification. Bitumen GWP results decrease by 3%, while Acidification results increase by 75%.

  2. Crushed and Natural, Coarse and Fine Aggregates and Lightweight, Natural and Manufactured Aggregates: the Manufacturing Transportation energy consumption and effects had previously been rolled up into the Manufacturing Material life cycle stage. They are now separated.
  3. Updated Materials: Updated LCI data for Crushed and Natural, Coarse and Fine Aggregates: There are no industry wide LCA reports available, but these LCI data were updated to use the same Ecoinvent profiles that have been used in recent years for the NRMCA and CRMCA ready mix concrete industry wide LCAs. Aggregates have relatively low effects on a per unit basis compared to other materials, but compared to the previous profiles, GWP and Energy results have increased by approximately 90-100%, with similar increases in the other LCA measures.
  4. Ready Mix Concrete Process: The energy profile for Ready Mix Concrete was updated to the profile developed in the Industry Wide NRMCA Ready Mix LCA of 2016.
  5. Updated Material: Updated density value for GluLam Sections.
  6. Updated Material: Updated LCI data for Sika Sarnafil© G410 PVC Membrane 60 mil.
  7. Updated Material: Updated LCI data for Sika Sarnafil© G410 PVC Membrane 72 mil.
  8. Updated Material: Updated LCI data for Sika Sarnafil© G410 PVC Membrane 80 mil.
  9. Updated Material: Updated LCI data for Sika Sarnafil© S327 PVC Membrane 60 mil.
  10. Updated Material: Updated LCI data for Sika Sarnafil© S327 PVC Membrane 72 mil.
  11. Updated Material: Updated LCI data for Sika Sarnafil© S327 PVC Membrane 80 mil.
  12. Updated Material: Updated LCI data for Mortar: Updated the LCI data for US and Canadian regions with mix information from the CCMPA CMU review.
  13. New Material: Added Grout-Coarse to the database with mix information from the CCMPA CMU review.
  14. New Material: Added Grout-Fine to the database with mix information from the CCMPA CMU review.
