Zone 1: Kitchen/Living

Zone 2: Bedroom 1

Zone 3: Master Bedroom

Windows / Doors

Triple-Glazed Windows:

• Energy efficient; low U-value of 0.9-1.0 compared to Single pane (5.8-5.9)
• The lower the U-value = better insulator
• Great sound barrier, on major road (28th Ave)
• Extra layers of glass reduces energy transfer
• 50% more efficient than single pane; 20% more than double pane
• Safety net; thicker windows overall.
• Can be hit with baseball bat 30 times before breaking
• CON: Ranges from $500-$1000, plus labor.
• Energy savings will eventually average this out.

Fiberglass Exterior Door

• Very energy efficient material to use for a door
• Poor conductor of heat & electricity
• Providing 4 times the insulating R-value of a wooden door.
• Resists extreme temperature fluctuations
• Highly weather resistant
• Longer overall lifespan
• CON: Ranges from $800-$1000 per door
• Resale value of 77%; saves on monthly energy costs.

Solar Infographics

There are 27, 370W panels being used to power this home.

Panels

04

The solar panel battery will be placed on the side of the home to connect to the panels.

To power the home, monocrystalline solar panels will be used.

The most sunlight will be received from the south direction.

Electrical Components

Different components of the home will use different amounts of energy

Cylindrical silicon ingot grown from a crystal of silicon of high purity

The total power needed to charge this home is a little over 16,000 Watts

Usage Percentages
