INTRODUCTION There is a nationwide trend toward constructing green buildings that meet sustainable design construction standards. To help identify and promote standards for environmentally responsible construction and high- performance operation, the U.S. Green Building Council (USGBC) developed the LEED® (Leadership in Energy and Environmental Design) rating system.

The LEED rating system is a widely recognized third-party certification standard that offers voluntary certification for buildings and accreditation of professionals. Although certification is voluntary, many federal, state, and local governments now require that the design architects or engineers on official projects demonstrate that they have performed the data collection and analysis necessary to meet the requirements of the LEED standard. (See Fig. 1.)

LEED® RATING SYSTEM OVERVIEW The LEED rating system includes several specific standards covering all aspects of the design, operation, and construction of buildings. The LEED for New Construction (LEED-NC) standard covers new commercial construction and major renovation projects and issues points for achieving credits in six categories of building design: Sustainable Site (SS), Water Efficiency (WE), Energy & Atmosphere (EA), Materials & Resources (MR), Indoor Environmental Quality (EQ), and Innovation & Design Process (ID). The LEED for Existing Buildings (LEED-EB) standard includes guidelines for sustainable efficiency and maintenance and for upgrades to meet current performance requirements. The LEED-EB system can be used to certify existing non-LEED buildings as well as buildings that had received certification under LEED-NC and are seeking re-certification. The USGBC encourages building owners to enroll in LEED-EB at the time of LEED-NC certification in order to achieve sustainable building performance. Carrier Commercial Service product and service offerings can contribute to meeting the goals of the LEED-EB standard through sustainable preventive maintenance solutions and planned upgrades to equipment and systems. Preventive Maintenance Service Agreements are available for all brands of rooftops, chillers, boilers, compressors, air-handlers, cooling towers, pumps, variable speed drives, controls and accessories. Carrier Commercial Services can also install and service building automation and control systems and energy saving solutions including microturbines and variable speed drives. These products can contribute to sustainable, efficient operation of a building and should be considered by owners seeking LEED-EB certification. The following two LEED standards are designed to address situations in which responsibility for sustainable choices is split between building developers/owners and tenants. The LEED for Commercial Interiors (LEED-CI) standard includes categories that are similar to those found in the LEED-NC standard, but with a focus on categories that may be under the control of the building owners or tenants. For instance, energy performance optimization addresses lighting and lighting controls, while resource utilization addresses interior building systems and furnishings.

The LEED for Core and Shell (LEED-CS) standard is complementary to the LEED for Commercial Interiors and establishes standards for basic building elements, such as structure and building level systems, which are under the control of the building developer. Other LEED standards specifically address green building requirements for Homes, Schools, Multiple Building Campuses, and Retail Operations. A pilot program is currently underway to establish a LEED rating system for Neighborhood Development. LEED FOR NEW CONSTRUCTION This paper will focus on the LEED rating system for New Construction. As noted earlier, LEED-NC 2.2 issues points for achieving credits in the following categories: Sustainable Site, Water Efficiency, Energy & Atmosphere, Materials & Resources, Indoor Environmental Quality, and Innovation & Design Process. Buildings and systems can achieve basic certification or reach the silver, gold, or platinum level of certification, depending on the number of points awarded. (See Fig. 2.) The LEED system does not certify products, however, the selection of products is critical to obtaining LEED certification for a building, because the right products can help meet the goals of green construction and contribute to earning LEED points. The choice of HVAC products, in particular, can have a significant impact on LEED certification, as the HVAC system directly impacts two categories that together contribute to 40% of the available points. (See Fig. 3.)

The achievement of points in any particular credit area depends on the combination of products selected and the specific application of those products. Therefore, no products or programs can claim that their use will guarantee that LEED® points will be awarded. Carrier HVAC products, which are built to high standards of energy efficiency and indoor air quality, can help building owners earn LEED points by contributing to the achievement of credits in the important categories of Energy & Atmosphere (EA) and Indoor Environmental Quality (EQ). Success in the category of Energy & Atmosphere recently became essential to LEED certification when the USGBC decided to institute a new requirement. The mandate requires that all newly registered LEED projects achieve at least two points in the Optimize Energy Performance area. These points are awarded under the EA category. Another LEED-NC category to which Carrier products may make a contribution is the category of Innovation & Design Process. In this category, Credits 1.1

through 1.4 allow points for exceeding requirements in one of the other 5 categories of the LEED-NC rating system (i.e., Sustainable Site, Water Efficiency, Energy & Atmosphere, Materials & Resources, Indoor Environmental Quality). Points in the ID category may also be earned by demonstrating innovative performance in other Green Building categories. One innovative Carrier product that may contribute to a credit in the ID category is the Carrier Microsteam® turbine generator. The Carrier Microsteam turbine provides sustainable energy recovery by using existing steam sources to generate usable electric energy. The following outline lists the sections in which the application of HVAC equipment can contribute to EA and EQ credits and identifies the LEED points available if the credit standard is met. Contact your Carrier Sales engineer to discuss an innovative HVAC system that may contribute to earning ID Credits.

Energy & Atmosphere (17 points) HVAC Contribution 12 of 17 points

Material & Resources (13 points)

Innovation & Design Process (5 points)

Sustainable Site (14 points)

Water Efficiency (5 points)

Indoor Environmental Quality (15 points) HVAC Contribution 5 of 15 points

ENERGY & ATMOSPHERE (EA) 12 HVAC-RELATED LEED® POINTS POSSIBLE NOTE: Two of the three prerequisites in the EA category relate to HVAC equipment. Carrier products can meet the applicable requirements of each of these relevant prerequisites. EA Prerequisite 2 – Minimum Energy Performance Establish the minimum level of energy efficiency for the building or system by specifying Carrier equipment that meets the energy efficiency and control requirements of ASHRAE 90.1-2004. EA Prerequisite 3 – Fundamental Refrigerant Management Reduce ozone depletion by specifying units that do not use CFC refrigerants. All new Carrier equipment uses non-CFC refrigerants. EA Credit 1 – Optimize Energy Performance 1 to 10 Points Reduce energy cost of proposed building compared to ASHRAE 90.1-2004 minimum tables. Carrier units that are designed for good part-load performance, heat reclaim, or system energy saving features such as demand control ventilation (DCV) can contribute to earning points. In addition, the Carrier HAP (Hourly Analysis Program) is an approved program for determining compliance with these requirements.

EA Credit 4 – Enhanced Refrigerant Management 1 Point Minimize the Ozone Depletion Potential (ODP) and Global Warming Potential (GWP) of the system. Carrier units that use reduced refrigerant charges and environmentally sound refrigerants, such as Puron® R-410A refrigerant, can meet the requirements for this credit. ODP/GWP calculation for acceptable charge of R-134a

• packaged unit—2.8 lb/ton • scroll or reciprocating chillers—3.30 lb/ton • centrifugal or screw chillers— 3.03 lb/ton

ODP/GWP calculation for acceptable charge of R-410A

• packaged unit—1.98 lb/ton • scroll or reciprocating chillers—2.11 lb/ton • centrifugal or screw chillers—2.17 lb/ton

EA Credit 5 – Measurement & Verification 1 Point Develop and implement a plan to account for building energy consumption over time. Carrier equipment control systems, such as the Carrier Comfort Network® (CCN) controls, can be configured to track energy usage and monitor the performance of fans, compressors, or heating devices. Data can be collected and used to develop trend logs.

INDOOR ENVIRONMENTAL QUALITY (EQ) 5 HVAC-RELATED LEED® POINTS POSSIBLE NOTE: There are two prerequisites in the EQ category, but only one relates to HVAC equipment. Carrier products can meet the applicable requirements of this prerequisite. EQ Prerequisite 1 – Minimum IAQ Performance Establish minimum indoor air quality (IAQ) performance by specifying units that meet the ventilation rates described in ASHRAE 62.1-2004. (applies to all airside equipment). Carrier units covered by this standard can meet the applicable construction and performance requirements. EQ Credit 1 – Outdoor Air Delivery Monitoring 1 Point Provide capacity for ventilation system monitoring. This credit requires monitoring of CO2 in densely occupied spaces and monitoring of outdoor airflow in other spaces. Carrier units that use DCV (when output can be monitored) or air-handling units with airflow stations can help qualify for this point. EQ Credit 2 – Increased Ventilation 1 Point Improve IAQ by increasing the outdoor air ventilation to 30% above that required by ASHRAE 62.1-2004. Carrier offers system options, such as energy recovery and outdoor humidity control, that can contribute to meeting this requirement while maintaining energy efficiency. EQ Credit 5 – Indoor Chemical & Pollutant Source Control 1 Point Minimize and control pollutant entry into building systems. Carrier air-handling units can be provided with a MERV (Minimum Efficiency Reporting Value) 13 filter system.

EQ Credit 6.2 – Controllability of Systems: Thermal Comfort 1 Point Provide individual comfort control for 50% of the building’s occupants. Carrier systems that may meet this requirement include VVT systems designed for small zones; underfloor air distribution systems; and individual room terminal units. EQ Credit 7.1 – Thermal Comfort: Design 1 Point Control and maintain humidity as well as temperature and comply with the requirements of ASHRAE 55-2004. Carrier rooftop units and air handlers coupled with Carrier controls can help to meet this requirement. CARRIER COMMERCIAL PRODUCTS AND LEED CERTIFICATION The chart on pages 8 and 9 lists the key components of the major types of HVAC systems and shows how Carrier products can contribute to points required for LEED certification. The achievement of points in any particular credit area depends on the combination of products selected and the specific application of those products. Therefore, no products or programs can claim that their use will guarantee that LEED points will be awarded.
