Taking into consideration the LEED Rating system, Energy and atmosphere (EA) contributes the most number of points. The opportunity to achieve EA credits involves initial design consideration to reduce building air conditioning needs up to selecting the most efficient air conditioning system.

Increasing efficiency can be accomplished with more efficient building envelope, building lighting, and HVAC systems, and by appropriately sizing HVAC systems. These actions contribute to a more efficient system; reduce energy demand and energy use. VRF systems powered by Digital Scroll technology is able to conserve 35% energy which helps green building developers optimize energy performance.

The Digital Scroll compressor is available in R410A. R410A has become the refrigerant of choice which deliver higher efficiency and less Total Equivalent Warming Impact.

VRF central air-conditioning systems powered by Copeland Digital Scroll™ have been specified in many prestigious projects in Asia including Tongji United Plaza in China — an 80,000m2 complex building with office, hotel, conference and commercial functions.  With VRF systems powered by Copeland Digital Scroll compressor using R410A, the project design demonstrated energy efficiency and integrated design as well as high reliability and flexible control and cost allocation.  It is already pre-certified under the Leadership in Energy and Environmental Design (LEED™) Core & Shell and is expected to achieve the Gold level.  The LEED Green Building Rating System is the nationally accepted benchmark for the design, construction, and operation of high performance green buildings.
