Top eco-friendly home design features to consider
There are many eco-friendly luxury home design features that designers and architects employ when sustainability is a top priority. Most buildings don’t utilize all eco-friendly features but instead use a mixed bag most conducive to the area and its resources. Features may include:
- Smart home technology: Smart thermostats, appliances, and other lighting systems ensure you’re only using energy when absolutely necessary.
- Rainwater harvesting: Recycling rainwater and using it as drinking, cooking, or bathing water makes for greener hydro use.
- Energy-efficient glass: Double- or triple-pane windows prevent heat loss or gain, so your energy systems don’t need to work as hard and damage the environment.
- Non-toxic finishes: Low-VOC paints or adhesives improve indoor air quality by lessening exposure to harmful chemicals.
- Renewable energy: Sources, such as wind turbines and solar panels, help lower your home’s carbon footprint through eco-friendly power generation.
- Green walls or roofs: Vegetation on your home’s roof or walls provides natural insulation, reduces rain runoff, and boosts indoor air quality.
Final thoughts
Wanting a more sustainable home doesn’t have to be the impossible feat you may perceive it to be. Luxury homes like Slip House, MO House, Casa Nirau, and Edgeland don’t employ every eco-friendly feature in the book, but they do utilize solar paneling, rainwater harvesting, and natural means of supporting airflow and heat transfer.
You can start small with smart home technology or a few solar panels, and when you’re in the market to buy, you just might find that more sustainable home design features are more commonplace.
