Sustainable houses also tend to be cheaper to run and better for your health.
Read on for tips to improve your house sustainability whether renovating or not.
What is a sustainable house?
There are 3 main factors which define a house as sustainable. Energy consumed, how long the house will last and its size.
There are 3 types of home, standard, passivhaus, and zero carbon principals house. A standard house uses a lot of energy. A passivhaus will significantly decrease your energy consumption, by improving its heating efficiency and minimizing the need for heating and cooling. Zero carbon houses are designed to minimise energy use and produce any additional energy need.
The average lifespan of a house is 70-80 years. A sustainable house will take into account the materials used and their life span. It should last more than a 100 years.
While impossible to leave no impact, house construction can be mindful and reduce its impact as much as possible.
Size matters. The larger a house the more materials and potential energy will be used. Every additional room will use more energy both in construction and everyday use. The design is important to ensure what’s built is what’s needed. It will also need to be easily adaptable for future occupants.
