AIR-COOLED LIQUID CHILLERS 30XAV 500-1150
There are a number of different LEED® products.
While the strategies and categories assessed remain 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
Platinum
60-79 points
Gold
50-59 points
Silver
40-49 points
Certified
The majority of credits in LEED® rating systems are
performance-based and achieving them is dependent on
the impacts of each component or sub-system to the overall
building.
While the LEED® green building certification programs do not
certify products or services, the selection of the right products,
systems or service programs is critical to obtain 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.

30XAV and LEED® certification
The LEED® (Leadership in Energy and Environmental Design)
green building certification programme is a pre-eminent
programme to rate the design, construction and operation
of green buildings with points assigned in seven credit
categories:
-- Sustainable Sites (SS)
-- Water Efficiency (WE)
-- Energy & Atmosphere (EA)
-- Materials & Resources (MR)
-- Indoor Environmental Quality (IEQ)
-- Innovation in Design (ID)
-- Regional Priority (RP).

The new 30XAV units from Carrier can assist building
owners to earn LEED® points in particular in the Energy
& Atmosphere (EA) credit category and help address the
following prerequisites and credit requirements:
■■ EA prerequisite 2: Minimum energy Performance
The 30XAV exceeds the energy efficiency requirements
of ASHRAE 90,1-2007; therefore it complies with the
presequisite standard.
■■ EA prerequisite 3: Fundamental Refrigerant Management
The 30XAV does not use chlorofluorocarbon (CFC)
refrigerants thus satisfying the prerequisite statement.
■■ EA credit 1: Optimise energy performance (1 to 19 points)
Points for this credit are assigned depending on the
energy cost reduction virtually achievable by the new
building, compared to ASHRAE 90,1-2007 reference. The
30XAV, which is designed for high performance especially
during part load operation, contributes reducing the
energy consumption of the building and therefore helps
gaining points within this credit. In addition, the Carrier
HAP (Hourly Analyses Program) can be used as an
energy analyses program complying 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 Globlal Warming
Potential (GWP) of the system. The 30XAV 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 30XAV. 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.

AIR TREATMENT
A number of green building certification programs exist in the
market and offer third-party assessment of green building
measures for a wide variety of building types.
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.
CONTROLS
The air conditioning system can use between 30 and 40%
of the annual building energy consumption. Selection of
the right air conditioning system is one of the main aspects
to consider when designing a green building. For buildings
with a variable load throughout the year 30XAV units offers a
solution to this important challenge.
