As the population on Earth grows, we need more space and buildings to house all the humans. As we move forward to create these spaces, it is important to keep thinking about the impact these buildings have on Earth. We only have one Earth, so we have to take care of it.
As new buildings are being created, ecodesign becomes key in designing sustainable buildings. Ecodesign takes into account the impact it has on Earth. This design method tries to be green and sustainable.
There are many criteria provided by the LEED to determine if a building is green. Builders try to include these criteria in order to get the LEED certificate. This certificate lets others know that from start to finish and beyond, the building is environmentally friendly.
The first criterion looks at the location of the building. It should provide access to public transit. This way, people do not have to drive all the time, and this could greatly reduce carbon emissions.
It is also important to think about where the building is being developed. It is more green to develop on land that has been developed previously rather than on new land. Builders can also retrofit an existing building by adding green features.
In order for a building to be sustainable, it needs to reduce its water usage. This is key to fighting climate change. This starts with using less water during construction. Low-flow toilets or rainwater collection systems can be put in place to optimize water usage as well.
Green buildings are required to reduce energy use. There are many ways to achieve this, including making sure all buildings are well insulated. This can also include using clean energy to heat the homes, like geothermal energy.
The construction materials have to be carefully considered as well. Ideally, local, sustainable, and recycled materials would be used for green buildings. Durable materials are also chosen, since they won't need to be replaced as often.
Bigger homes are not as sustainable. According to LEED, a carbon-neutral home ranges from 900 to 2850 sq. ft. For homes above this threshold, it would be harder to obtain the LEED certification.
Being sustainable doesn't stop with the building itself or the amount of energy it uses. It also keeps the occupants in mind. The indoor environment quality is just as important. This can include air cleanliness, temperature control, and noise pollution. Some paints and building materials can be toxic and detrimental to our health. Builders have to consider improving ventilation and using clean materials.
Windows are great for when we want to check out what's outside. They can also provide great views. Have you ever thought about where windows are placed? Window orientation needs to be taken into account when thinking green. Depending on which direction the window faces, it could affect your energy use. A south-facing window is generally more green in Canada, since it brings in heat during the winter.
Green buildings are more cost-effective to maintain. It may be difficult to go green all of a sudden. We could try to take little steps towards being green. We could start by consuming locally and in moderation. You can choose materials that do not need to travel a long way to their destination. It is important not to use up materials before they can be replenished.
Maybe changes in zoning laws and restrictions could encourage more green buildings in the city. With more green buildings, maybe it would be feasible to reach carbon neutrality soon. What else can we do to promote green buildings?
