8,760-hour cooling & power analytics

We transform cooling into compute power
This simulator will show you exactly how

Your power envelope has one weak point: your mechanical cooling (AKA chiller plant). It drives your peak PUE, and on the hottest afternoon of the year it decides how much IT your site can carry. IceBrick changes how that cooling operates — in a way no other system can. Give us a few details about your data center and we'll run all 8,760 hours of your year to show you exactly how much headroom you can reclaim: typically 5–15% more IT capacity behind the grid connection you already own.

Question 2 of 8
Where does your data center live?

Aside from compute, weather is the single biggest driver of cooling cost. Click the hub closest to your site — we will synthesize 50 years of hourly dry-bulb and wet-bulb from that location's climate normals.

Question 3 of 8
Name Your Power Envelope

Every project starts from one of two numbers — the substation connection you were offered, or the IT nameplate you want to install. Type yours into its box and continue from that box: the other quantity is derived for you at the design day. The two sliders below the boxes apply to both paths.

Choose your Substation feed (MW)
Type a number above and this column reads it as your substation connection.
Choose your IT-Nameplate (MW)
Type a number above and this column reads it as your IT nameplate.
How much of the connection operations may actually use at the worst hour.
UPS losses, distribution, white-space fans, lighting, security, offices. A modern site with efficient UPS lands near 8–10%; older estates run 12–16%.
Question 4 of 8
How do you reject that heat today?

Pick the cooling cascade that matches your plant. This decides how much of the year is free, how much runs on water, and how much lands on a compressor.

True Waterless Cascade

What leaves the plant. Return is always 10 K warmer. The same water temperature as the hall sliders on the next question — move either.
Question 5 of 8
Is your data hall air-cooled or liquid-cooled?

This decides what the next question even means. A liquid hall has a CDU between your facility loop and the chips, and the temperature that matters is the one the cold plates are promised. An air hall has chilled water going straight to coils, and the temperature that matters is what leaves the plant. Pick one and we will draw your loop.

Inside the data hall

What leaves the plant and enters the coils. The same slider as in the next question — move either.
Hot air that short-circuits the containment and lands on the server inlet. Raises the inlet and outlet shown here; the plant itself is priced on the chilled-water temperature, which this does not change.
Outdoors: the chillers’ own discharge recirculating over their intakes on the 2nd–5th day of a heat wave. Mirrors the slider in the next question and is applied by the engine above the trigger threshold.
Question 6 of 8
What water do your racks actually get?

Your IT does not see facility water — it sees whatever comes out of the CDU, one heat exchanger later. So we ask for the number your racks are promised and the step the CDU adds — the SLA ceiling comes on the next page, where IceBrick makes it usable. Facility water is then whatever the plant has to make to deliver it, and that is the loop the entire before analysis runs on.

“We're seeing many of our largest customers are talking about water temperatures that are more in the 80–86 °F (27–30 °C) range, not 104–122 °F (40–50 °C)”

On the 2nd–5th day of a heat wave the condensers stop seeing the weather station's ambient — their own discharge recirculates over the intakes. Estimate the degrees that adds. It is applied only in hours above 90 °F (32.2 °C), and only to the kW/ton of the chillers IceBrick avoids: once the Storage cuts more than ~30% of the plant's load, the recirculation cell collapses and the surviving machines get the real ambient back. Leave at zero to model no recirculation.
The ambient above which the recirculation cell establishes and the factor is applied. Below it the condensers breathe the true weather-station air.
Question 1 of 8
What is this run for?

This simulator runs two distinct advanced thermal-management methodologies, for two separate use cases. The IceBrick system can be deployed as a means of acquiring power flexibility — a firm curtailment you commit to the grid for a demand-response event — or to optimize your power envelope — more IT behind the connection you already own, every hour of the year. Pick the use case; the questions that follow describe your plant, and the same weather, the same chiller and the same 8,760-hour baseline serve either one.

Speed to Power — acquire power flexibility Size IceBrick to the night before an event and commit a firm curtailment for a demand-response window — the number you can put in a utility contract, on the day the grid actually peaked.
Power Envelope Optimization Size IceBrick to shave every design-week peak, unlock IT capacity under the same connection, and report PUE, water and the freed megawatts hour by hour.
Where does the ice plant charge from?
The site's own connectioncharging must fit under the same ceiling the store protects
A separate non-firm feed — night onlya second substation or a non-firm agreement carries the charging draw; it never appears on the site meter, and it cannot be relied on by day
Question 7 of 8
The demand-response event

Utility calls are usually 13:00–19:00 and run four hours. The store is sized to what the night before can freeze under your own operational limit; the grid picks which ten hours of the year we show you first.

hour the window opens · discharge ramps up over the 7 minutes before it
preset 4 h · adjustable 1–8 h
the site's default grid is preselected · official 2025 peak hours where published, the site's hottest days otherwise
Question 7 of 8
Go higher

The same loop with IceBrick tied in at the CDU. Watch the same spike again: the DCIM sees it the moment it starts, IceBrick is dispatched, and the cold wave reaches the CDU HX ahead of the heat — the hall never feels the hour. That interception, guaranteed under SLA, is what lets you commit to the warmest supply your rack architecture allows.

Question 8 of 8
One last look before we run the year

This is the baseline operating matrix we will simulate. Change anything you like — you can also come back and re-run with different answers at any time.
