Stop guessing tonnage.
Engineer the equilibrium.

Hi, I'm Dia Shah, an incoming Junior at Round Rock High School, Texas and an individual passionate about sustainability, energy efficiency, and contributing to a greener environment! Based in Texas, I'm dedicated to helping individuals and businesses optimize their energy consumption through smart, tech-based solutions like the Energy Optimizer and Zone Planner.

Breeze is my vision to help people with the tools and knowledge they need to make informed decisions about energy usage, particularly in HVAC systems which account for 52% of building energy consumption. Additionally, as a person who could never live without an AC, I'm driven to achieve a level of comfort and sustainability through every-day appliances!

How Load Calculations Work

Breeze uses the ASHRAE Manual J method to calculate how much cooling your home needs. It measures heat flowing in through walls, windows, and the roof, then adds heat from people, lights, and appliances.

What is the Equilibrium Index?

The Equilibrium Index is a single score that balances four things — how comfortable your home will be, how much it costs to run, the carbon footprint, and whether the equipment is the right size. A higher score means a better overall balance.

What-If Analysis Explained

What-If Analysis lets you test upgrades before spending money. Toggle options like better insulation or a higher-efficiency system to see how much you could save each year without committing to anything.

Understanding Peak Demand

Peak demand is the time of day when your AC works hardest: usually 3–7 PM in summer. Running your AC heavily during these hours costs more because electricity rates go up. Pre-cooling your home beforehand is a simple way to shift that cost.

Tons of Cooling — What Does That Mean?

"Tons" in HVAC doesn't mean weight — it's a measure of how much heat your AC can remove per hour. A 1-ton system removes 12,000 BTUs of heat per hour. Most homes need 2–5 tons depending on size, climate, load, and insulation.

Why Do HVAC Systems Use So Much Energy?

HVAC systems account for roughly half of all energy consumed in US buildings. This waste stems from leaky ductwork, older equipment, poor insulation, and schedule misalignments that continuously heat or cool empty spaces.
