Today is the summer solstice. This is the longest day of the year, even though the summer is only getting warmer for the next three months. Download my free Triangle Sundial that you can print and test the sun angles yourself.
Due to the thermal lag of the earth’s mass, the days will continue to get hotter despite the sun being the highest in the sky today. As discussed in the previous article, using solar angles can be very helpful for reducing energy costs in architect considers them in the design. Of course, the opposite is also true. A home can actually face into the warm summer sun and increase the cooling costs. The sundial illustrates just how much these solar angles change througout the year.
Please send me photos of your sundial in action!
