We as a LEED Consultant, LEED-certified buildings can potentially have highly efficient envelopes with complex glazing systems because they are high-performance constructions. The amount of energy required for heating and cooling is reduced using these features. Your building will be 40–70% more energy efficient when you include additional energy-saving elements like LED lighting and Energy Star appliances. Over time, this can save a significant amount of money on operations. Tight building envelopes and cutting-edge filtering systems that raise interior air quality are prerequisites for LEED certification.
