Carbon Footprint: Also known as the climate-change metric, the carbon footprint is the number of greenhouse gasses emitted during a human prompted process and is expressed as the equivalent tons of CO2 (Carbon Dioxide) generated.

Pro Tip: Cove.tool can help understand the impact of energy and energy cost which is a good indicator of the carbon impact of the element.

Impact on Exterior Space: Facades not only impact the energy use of the buildings they belong to but depending on the material reflectivity, they also add a burden to the exterior world by creating hot spots. An extreme example of this is the Walkie Talkie in London, whose bulge and mirrored surface microwaves nearby buildings and public spaces resulted in a number of lawsuits and other urban issues. 

Energy Use: A building’s energy use refers to the energy required to operate and sustain it. Depending on the facade design, the active and passive strategies implemented, the energy use of the building can drastically vary. This leads to a much high Energy Cost, making the building expensive to operate.

(Pro Tip: Cove.tool can help understand the impact of energy and energy cost of specific façade decisions. A user can study the impact of varying glazing percentages, adding overhang, fins, or other façade elements on energy use and cost.)

Comfort: Occupant comfort is the final test of the success or failure of a project. Doing Daylight and Glare studies during the early stages of the design process can create a better design.

Acoustic Comfort: Acoustic comfort is the well-being perceived by a building occupant in regards to the acoustic quality of their environment. Acoustics have the ability to significantly reduce occupant productivity. Despite its impact, this metric is typically considered only when the project type is a theater or auditorium. One great factor of acoustic comfort is the façade's materiality. Providing noise-reducing insulation or materials with similar properties can minimize noises and enable higher productivity levels in the building users.
