Energy codes and compliance

More energy codes: Chicago 2022, Minnesota 2024, New York State 2020, New York City 2020 and 2025, and Oregon 2021 and 2025, with their own rules and building performance factors. See Energy codes and compliance paths.
Each code lists only its own compliance paths under Rating System. To use the ASHRAE 90.1 alternative an IECC edition allows, choose that 90.1 edition as the energy code.
Performance Calculations (formerly “PCI & PCIt Calculations”): pick the cost index or an energy index. ASHRAE 90.1-2022 and Oregon 2025 offer site energy, source energy or carbon, with optional local conversion factors. 90.1-2022 also counts the code-required on-site solar.
Energy Cost Budget Method and Total Building Performance have their own calculations, with each edition’s limit and renewables rule.
Pinned project cards on your Home tab show the rating system under the name and lead with the conclusion’s main figure, such as LEED points or the PCI with Pass or Fail. See Your Home tab.
LEED v4, 2024 Update: source energy is worked out with both ASHRAE 90.1-2022’s and ENERGY STAR Portfolio Manager’s source-to-site ratios, and the one giving the higher savings is used and named in the conclusion. Canadian projects use Portfolio Manager’s current ratios for Canada. Propane and gasoline entered in gallons now use their own energy content, and fuel oil and diesel in gallons the same GHG factor as in MBtu. See Show compliance.
LEED in Canada: choose the project’s province or territory under General Information. GHG emissions use its electricity factor from the LEED calculator and natural gas at 116.4 lb CO₂e per MMBtu. Electricity had no emissions before. See How results are calculated.
LEED v4 pilot credit (ACP 110): General Information now shows the eGRID subregion, which its GHG metric uses. On an existing project, check it: while the field was hidden, the first subregion in the list, ASCC Alaska Grid, could be saved.
Conversion factors in the conclusion: a conclusion that uses GHG factors, source-to-site ratios or a code’s own source or carbon factors lists them in a small line at its end. See Show compliance.
Archiving is now for modelers only. Archiving a project unpins it and hides it from the client, whose lists leave it out and whose review link no longer opens it. Your Projects tab hides archived projects unless you tick Show archived. See Projects and phases.
Massachusetts: MA Energy Code 2021 Targeted Performance checks each use type’s heating and cooling TEDI against the code’s limits, entered when you add the conclusion (it compared site energy with the baseline). Relative Performance no longer subtracts on-site renewable energy, and both it and 2020 Pathway 1a ask for a BPF first. 2020 Pathway 1b passes on a site or a source energy basis. See Show compliance.
NGBS with IECC 2018: the conclusion gives the 2020 NGBS Energy Efficiency points and level, Bronze to Emerald. See Show compliance.
LEED 2009 Core and Shell now gets its own points for Optimize Energy Performance, 3 to 21. It was scored on the New Construction table, 1 to 19.
Living Building Challenge, ILFI Zero Carbon and ILFI Zero Energy: the conclusion checks each certification’s energy targets for a new building, renovation or interior, and sets out the renewable energy required and provided. See Show compliance.

Fill Baseline from Energy Code

The baseline HVAC system now follows the compliance path. The Energy Cost Budget Method uses the budget systems and IECC Total Building Performance the standard reference design systems, both pre-selected from your proposed design.
IECC 2009 and 2012 now fill the envelope and lighting from their own tables.
Chicago 2022 and New York State 2020 fill Total Building Performance from their base IECC edition.

SimReader

Drag files onto the Baseline and Proposed tiles, and reorder them with the arrows or by dragging.
Next: Results reads the files for you. SimReader warns when the baseline and proposed rate names differ.
Unmet load hours and process loads are shown as tables. Unmet load hours upload to InverseHub, where an Unmet Load Hours card can show them.
On-site renewables and exceptional calculations get their annual cost from the proposed design’s rate until you type your own.
One design only: a Parametric Analysis with just the base design reports that design on its own, and the project lists and the client’s Home show it as Base Design Only. SimReader says so in its hints, and warns when the baseline and proposed lists hold the same file. See Choose the analysis type.
New off-site renewable energy: a new section on the Results page, between on-site renewables and exceptional calculations, for Tier 2 new off-site and community renewable systems. For LEED v4 with the 2024 energy update, InverseHub counts it toward the GHG emissions reduction only, and shows each system’s offset and its share of the proposed design’s site energy and GHG emissions for your Renewable Energy credit. See LEED and other programs.
Every project in SimReader: Project Name lists all your projects, pinned ones first, so a project no longer has to be pinned first. + New InverseHub project… creates one without leaving SimReader. See Read and upload results with SimReader.
Share right after uploading: Copy Review Link copies the report’s link for your client or reviewers, and Open in InverseHub opens the project. A new project’s first upload no longer asks to replace results it doesn’t have.
Create a free account in SimReader’s sign-in dialog opens InverseHub’s sign-up page.
Stay signed in until you sign out: with Remember me, now ticked to start with, SimReader keeps an encrypted sign-in instead of your password. Changing your password on InverseHub ends it. After this update, SimReader may ask you to sign in once.
Open InverseHub signed in: the new InverseHub menu on SimReader’s toolbar opens the project, Home, Projects, Subscription or Account settings in your browser without signing in again, and so does Open in InverseHub after an upload. See Open InverseHub from SimReader.
A new phase isn’t a new project: uploading a phase from SimReader no longer counts toward your plan’s new projects. Only projects you create on the Projects tab count, as the plan says.
Read again after a rerun: when a run rewrites the report files, SimReader waits until it’s done, reads them by itself and shows what changed: the savings and costs before and after, the end uses that changed, and tinted cells. Compare with the results before the rerun, your last upload or an earlier read. Include? and Process ticks and typed ECM names are kept. You can turn it off in Settings. See When you rerun the model.
The analysis type comes from the project: SimReader takes it from the InverseHub project you choose and locks it, and InverseHub refuses an upload of another type. You can change a project’s type in its menu (⋮) on the Projects tab, even after results are uploaded; then upload each phase again. See Change the analysis type.

Reviews and comments

LEED ID+C, 2024 Update: when you add the conclusion, choose the baseline envelope you modeled (new construction or existing conditions before renovation). The conclusion and the summary give that envelope’s points only. See Show compliance.
Conclusion out of date: after a change that moves a conclusion’s figures, such as a new eGRID subregion, InverseHub lists what changed and offers Refresh to add the conclusion again; the Conclusion card reminds you until then. See Show compliance.
Shorter conclusions: each result comes first with its numbers, then the requirement, and key numbers are in bold. After a pass, the conclusion states that the building performance meets the minimum performance the compliance path requires. LEED conclusions list the points for each metric. See Show compliance.
A summary at the top of the review page: the status and the steps to come, the modeler, the savings, the energy code, the upload date and the start of the conclusion, then links to each section with its open comments. See Reviewers.
The summary shows what matters for the project’s purpose: LEED points with energy cost and GHG reduction, the performance against the code’s target, the 179D deduction, or the annual cost savings. The figures come from the conclusion, or from the results for a conclusion added earlier. See Reviewers.
Send my comments to the modeler on the Comments tab emails the modeler your open comments in one message. Commenters get an email when the modeler replies or resolves a comment.
The Comments tab filters by All, Open or Resolved, and Show in the table jumps to a comment’s value.
Clients see Your modeler and Needs your attention on their Home page, and Open review and Update status on each project. See Clients.
A review page opens from its link, or from Open review for the project’s client. A review page saved by its project number, without the link, asks for the link again. An archived project’s report, comments and PDF open only for its modeler.
Comment without a PIN: anyone with a review link comments after confirming their email once with a 4-digit code, so your clients can pass the link to their own clients. Invitation emails let people comment in one click, and the page shows Commenting as with Not you?. The Comments tab takes a general comment on the whole report. See Review a shared project.
Choose who can comment: after Copy Link, pick Anyone with the link, My client and invited reviewers or My client only for the project. Your client, signed in, can always comment. Invitations no longer carry a PIN. See Share and handle comments.
Your Home tab lists the projects whose comments Need your reply, filters your pinned projects by status, and shows each one’s cost savings, results date and open comments, with your plan’s use alongside. See Your Home tab.
The Projects tab is one list, grouped by client, with each project’s status, phase, results date and open comments. Search by name, client or description, and filter by status or Pinned only. See Your Projects tab.
Click a status to change it, on a Home card or in the Projects list.
Two statuses have shorter names for every kind of project: Accepted (was Awarded/accepted) and Archived (was Inactive/archived). Projects keep their status.
Clearer phase names: “Construction Documents: Final Model” instead of “Construction Documents-Final Model”, and the review phases are now Preliminary Review Model, Final Review Model and Approved Model, for LEED and plan review alike. Projects keep their phases. See Modeling phases.
Clients’ Projects tab uses the same list, grouped by modeler, with archived projects at the end. See Clients.
Clients can remove a project from their Home with the × on its card, with Undo. It stays on the Projects tab. See Clients.
On the client’s Home, a parametric project no longer shows Cost savings, which read 100% with no baseline to compare. Its Energy costs shows the base design’s cost only.
