# EUI & Intensity

> Rank sites by energy use per square foot and spot the outliers in your portfolio.

</Tip>

The EUI & Intensity dashboard ranks the sites in your portfolio by [energy use intensity](/platform/glossary#energy-use-intensity-eui) — energy use per square foot — so you can quickly see which buildings are outliers for a chosen commodity and time window.

You'll find it in the **Sites** area, alongside Portfolio and Compare: open [**Sites > EUI & Intensity**](https://dash.nectarclimate.com/analytics/intensity).

## Filters

All three views share one filter bar at the top of the page:

| Filter         | Description                                                                 |
| -------------- | --------------------------------------------------------------------------- |
| **Date range** | Month-range selector with presets (Last 12 months, This year, Last 2 years) |
| **Commodity**  | Choose which utility type to analyze (electricity, gas, etc.)               |
| **Sites**      | Optionally narrow the analysis to specific sites                            |

Until you pick a date range, the page shows preset buttons to get you started.

## Views

The dashboard has three tabs that share the same filters.

### Ranking

A horizontal bar chart with one bar per site, sorted from highest to lowest intensity. The longest bars at the top are your outliers. Click any bar to open the site's [intensity breakdown](#site-intensity-breakdown).

### Size vs consumption

A scatter plot of building size (square footage) against annualized usage. This helps you tell apart a site that's genuinely inefficient from one that simply uses more energy because it's larger.

### Over time

A trend view of intensity across the selected window, useful for spotting seasonal patterns or the impact of an efficiency project.

## How intensity is calculated

Intensity is your site's usage divided by its **gross floor area**, scaled to a full year. Nectar uses each site's gross square footage as the denominator — it does not adjust for occupancy. This is intentional: if a site's occupancy hasn't been applied yet, it will stand out as an outlier here, which is exactly what you want when auditing your portfolio.

To set or correct a site's area, edit the site in **Settings > Company > Sites**.

## Sites without square footage

A site needs a floor area to have an intensity figure. Sites that have usage but no square footage (or an area of zero) are listed in a separate **Missing square footage** section below the charts, rather than being shown with a misleading value. Add the area in site settings to bring them into the ranking.

## Site intensity breakdown

Clicking a site opens a breakdown panel showing how its intensity figure is built — the total usage for the period, the gross area, the number of days with data, and the resulting annualized intensity. This makes it easy to verify a number or understand why a site landed where it did.

## Frequently asked questions

<AccordionGroup>
  <Accordion title="Why is a site missing from the ranking?">
    A site needs a floor area to appear in the charts. Sites with usage but no square footage are
    listed in the **Missing square footage** section. Add the area in **Settings > Company > Sites**
    to include them.
  </Accordion>

  <Accordion title="Why does intensity use gross area instead of occupied area?">
    Using gross square footage means a site whose occupancy hasn't been applied yet still shows up as
    an outlier — which helps you catch sites that need attention. The breakdown panel shows the exact
    inputs behind each figure.
  </Accordion>

  <Accordion title="Can I analyze more than one commodity at once?">
    The dashboard shows one commodity at a time. Switch the **Commodity** filter to compare a
    different utility type.
