Staying warm in winter and cool in summer, without auxiliary heating and cooling.
Two big factors in keeping your house both warm in winter, but also cool in summer are correct window shading and thermal mass.
Correct shading greatly reduces the inside temperature of your house throughout the warmer summer months, improving your comfort levels without any auxiliary cooling. However, did you know that incorrectly positioned and sized shading could also block out the warming winter sun, leaving you with a fridge for a house during winter?
Window and wall shadings are crucial in reducing unwanted heat gain during the hot summer months. Many people are unaware that unprotected glass is actually the greatest source of heat gain to a house. Effective shading such as window awnings or shutters, eaves, pergolas and even plantings can block up to 90% of the summer heat.
It is crucial that window shading be designed to block out all summer sun, whilst still allowing the winter sun to penetrate deeply into the home. This is easily done through correctly sized and located shading, paired with good planning and good design. Poorly designed fixed shading structures can end up blocking out the winter sun and natural winter heating, resulting in a cool house during summer but an even colder house in winter. During the winter months, the sun is at a much lower angle, which means that with the correct shading devices; this lower angle winter sun can penetrate through or under the shading and enter deep into your home. However, it is a fine balance with the specific shading for each specific window size, location and orientation.
