Building Certifications

There are a few organizations that provide certifications for buildings that are built and operated more sustainably. Just like food getting certified as organic, humane, or non-GMO, it allows consumers to know that the building has met certain guidelines and requirements, influencing their decision to buy it. Developers use these certifications because they want to do good things for the environment but it also allows them to market the building to environmentally conscious consumers. An individual can even get a certification for their own home to know that they are living in a home that is more sustainable and to prove that for the next buyer. More recently, governments are adopting building development codes that require certifications or have similar requirements. 

However, there is still a wide difference between basic building codes and how sustainable you can build and operate a building. Certifications for buildings mostly look at the materials used to build the building, if the appliances being used are electric, and how much energy it takes to operate the building. Reducing the energy used in materials and operating a building takes many different things into account. For example, you can orient your building to reduce sunlight heating the interior or add more insulation to require less heating.
