There are a number of different LEED ® products . Whilst the strategies and categories assessed remain the same , the point distribution varies to address different building types and application needs , for example according to New Construction , Schools , Core & Shell , Retail and Healthcare . All programmes now use the same point scale .

110 possible LEED points

80-110 points

40-49 points Certified

50-59 points Silver

60-79 points Gold

Platinum

The new 30XWHV units from Carrier can assist building owners to earn LEED ® points in the Energy & Atmosphere ( EA ) credit category and help address the following prerequisites and credit requirements :

■■

EA prerequisite 3 : Fundamental Refrigerant Management The 30XWHV does not use chlorofluorocarbon ( CFC ) refrigerants satisfying the prerequisite statement

■■

EA credit 1 : Optimise energy performance ( 1 to 19 points ) One component for this credit requires the energy cost reduction of the proposed building compared to ASHRAE 90.1-2007 minimum tables and beyond the performance level required to meet EA prerequisite 2 .

The 30XWHV is designed for efficient part-load performance and therefore satisfies this LEED ® credit . In addition , the Carrier HAP ( Hourly Analysis Program ) can be used in the energy analysis component of this credit . The HAP program can run analysis programs that comply with the modeling requirements for this credit and produce reports that are easily transferable to LEED ® templates .

■■

EA credit 4 : Enhanced refrigerant management ( 2 points ) With this credit , LEED ® awards systems that minimise the Ozone Depletion Potential ( ODP ) and Global Warming Potential ( GWP ) of the system .

HEATING

The majority of credits in LEED ® rating systems are performance-based and achieving them is dependent on the impacts to the overall building . The contribution any product or system may make to the points achieved depends on how it impacts the entire building and its operations .

Whilst the LEED ® green building certification programme does not certify products or services , the selection of products or service programmes is critical to obtaining LEED ® certification for a registered project because the right products or service programmes can help meet the goals of green construction and ongoing operation and maintenance .

The choice of heating , ventilating and air conditioning ( HVAC ) products in particular can have a significant impact on LEED ® certification , as the HVAC system directly impacts two categories that together influence 40 % of the available points .

Overview of LEED for new construction and major renovations

The 30XWHV uses a reduced R134a charge and therefore contributes toward satisfying this credit under LEED ® .

Note : This section describes the prerequisites and credit requirements in LEED ® for New Construction and is directly related to the 30XWHV . Other prerequisites and credit requirements are not directly and purely related to the air-conditioning unit itself , but more to the control of the complete HVAC system . i-Vu ® , Carrier ’ s open control system , has features that can be valuable for : --

EA prerequisite 1 : Fundamental commissioning of energy management systems

-- EA credit 3 : Enhanced commissioning ( 2 points )

--

EA credit 5 : Measurements and verification ( 3 points )

Note : Products are not reviewed or certified under LEED ® . LEED ® credit requirements cover the performance of materials in aggregate , not the performance of individual products or brands . For more information on LEED ® , visit : www . usgbc . org .
