What you see in Sefaira Architecture vs Sefaira Systems

Sefaira includes 3 different product types and depending on the products you are entitled to you will see different parts of the product. 

The three products are:

  1. Sefaira Architecture (just have common features and Sefaira Architecture features)
  2. Sefaira Systems (just have common features and Sefaira Systems features)
  3. Sefaira Architecture + Systems (have all features)

This article explains what you see with different products when they are allocated to you.

1A. Common to all products - Plugin to upload models and tag entities / generate views

The Plugin is used by both products to upload custom geometry into the Web-application. Both products can:

  • Tag entities
  • Draw lines to create zone boundaries (SketchUp)
  • Use rooms to set zone boundaries (Revit)
  • Generate views to simplify geometry sent to Sefaira (Revit)

1B. Architecture Only - Analysis in the drawing environment

Architecture users get the analysis features available in the 3D drawing environment (Revit or SketchUp). This analysis occurs in the Sefaira Plugin and includes

  • Energy Analysis using EnergyPlus with a single-zone-per-foor model
  • Daylight Analysis using Daysim

This is visible only to users who have:

  • Architecture
  • Architecture + Systems


2A. Common to both products - Web Application.

Architecture and Systems have the same basic Web App. This web-app has the following attributes:

  • It runs on EnergyPlus
  • Projects can be shared in this web-app regardless of the product that you have
  • Results for a shared project are always the same regardless of the product you have

The image below shows what the basic web-application looks like. 

2B. Systems Only - Additional Web App features.

Although in Systems the Web App is the same as Architecture, there are more input controls and more outputs that are visible. All having Systems does is make these inputs and outputs visible to you.

This is visible only to users who have:  

  • Systems
  • Architecture + Systems

The 4 key areas where inputs and outputs differ for Systems are:

  • More HVAC Systems (the HVAC System type dropdown offers 13 system choices instead of 3)
  • Air-side and Water-side Input tabs. These input tabs (on the left side) offer extra control of the HVAC system configuration. If the project is shared, these settings are remembered for the Architecture user if they Clone the Iteration, Copy the Project or make edits to other parts of the project.
  • Plant Sizing and Zone Sizing Output tabs. These output tabs (on the right side) provide extra detail for outputs such as HVAC equipment size, chiller size, boiler size and zone equipment sizing.
  • Results Grid and Response Curve Options. Systems users see more outputs available for the dropdown in the Results Grid and when running response curves. They essentially see variables that exist in the Plant Sizing and Zone Sizing output tabs.
