Maximizing Solar Gain for Custom Home Building in North Stonington, CT

As daylight hours shorten in late fall, window orientation becomes a critical factor in maintaining comfort and energy efficiency in your home. For those considering custom home building in North Stonington, CT, understanding how to harness solar gain can make a significant difference in warmth and utility costs.

• South-facing windows are ideal for capturing the sun’s lower angle during late fall and winter, maximizing passive solar heating throughout the day.
• Positioning windows within 5–15 degrees of true south ensures optimal solar gain, helping to naturally warm living spaces as the days grow shorter.
• Homes designed with their longest dimension facing south allow more rooms to benefit from sunlight, reducing reliance on artificial heating.

1. Prioritize South-Facing Glazing

• Place major living areas and large windows on the south side of the home to absorb the most sunlight during late fall.
• Even a slight shift—up to 30 degrees east or west of south—still provides effective solar gain.

2. Use Thermal Mass Strategically

• Incorporate materials like masonry or concrete floors near south-facing windows. These absorb heat during the day and release it after sunset, maintaining warmth overnight.
• Avoid carpeting over thermal mass surfaces to ensure maximum heat absorption and release.

3. Minimize North-Facing Fenestration

• Limit windows on the north elevation to reduce heat loss, as these receive minimal solar gain and can contribute to colder indoor temperatures.

4. Optimize Overhangs and Shading

• Design overhangs to allow sunlight in during late fall and winter, while blocking higher summer sun to prevent overheating.
• void excessive shading from trees or structures on the south side during fall, as this can reduce valuable solar gain.

• The region’s climate benefits greatly from passive solar design, especially as temperatures drop and sunlight hours decrease.
• When planning custom home building in North Stonington, CT, select a site that accommodates south-facing living areas and consider local sun angles for optimal window placement.

Key Takeaways for Custom Home Building
