Читать книгу Creating an Eco-Friendly Home & Workplace - Paul Hymers - Страница 12

An eco-friendly home is a home blessed with light.

Light brings with it security, serenity and good health. It reacts with chemicals in our skin to create vitamin D, feeding our bodies with calcium, but much more than that it engenders a sense of wellbeing that feeds our minds, and lifts our hearts and our spirits. It is no coincidence that when homes are judged for fitness under public health laws, the amount of daylight afforded to rooms is measured. A minimum of ten per cent window area to floor area has been considered the minimum for habitable rooms for some time, and if you’ve ever had to spend time in a basement away from daylight, you’ll understand why that is. With advances in glazing, such as Low-e glazing (see diagram, below) we can stretch that ratio much further to give us the best possible exposure to natural light.
