Why Green Is GoodGreen, the iconic color of plants, is the symbol forsustainability in buildings. Green is good for the triplebottom line (people, planet, and prot). Green build-ings are:

Good for occupants (healthier and more comfort-able working space)

Good for our environment (reduced resourcedepletion and higher sustainability, which helpspreserve the earth for future generations)

Good for business (higher employee productivity,lower energy and life cycle costs, higher client at-traction/retention, higher resale value, and en-hanced public relations)

A signicant goal for greener buildings is reducingenergy and water usage while enhancing the qualityof indoor air. This goal is attainable largely by optimiz-ing the buildings automation system.

Wachovia Bank Building, Tampa, Florida(ENERGY STAR Labeled and pursuing LEED Gold)

Controls and Building CerticationsAlthough any building may be built or retrotted withvarious enhanced green characteristics, signicantadvantages exist in obtaining building certicationby one of the green organizations , such as ENERGYSTAR and the U.S. Green Building Councils Leadershipin Energy and Environmental Design (LEED ) GreenBuilding Rating System. A buildings certication pro-

vides proof of its triple bottom line.KMC Controls has been a member of the U.S. GreenBuilding Council (USGBC) since the early days of theorganization. The USGBC is a non-prot organizationcommitted to a prosperous and sustainable future forour nation through cost-efficient and energy-savinggreen buildings. According to the USGBC, buildingsin the United States are responsible for 39% of CO 2 emissions, 40% of energy consumption, 13% waterconsumption, and 15% of the gross domestic productper year, making green buildings sources of signi-cant economic and environmental opportunity.

Green buildings are found in many sectors, and KMCproducts have been minimizing energy use while opti-mizing occupant comfort in many government, school,hospital, hotel, office, and other commercial buildingsfor decades. To help you obtain green certication aswell as ensure that your facility operates as it was initiallydesigned, KMC provides a comprehensive approach toautomating systems within commercial and institutionalfacilities. Our systems can manage heating, ventilating,and air conditioning as well as smoke control, lightingcontrol, daylight harvesting, rainwater harvesting andlandscape irrigation, monitoring/management of poweruse and (alternate energy source) generation, data col-lection with logging and trending, and a host of otherapplications.

Whether your green building is small or large, KMCsproducts can play critical roles in attaining certi-cation in the LEED, ENERGY STAR, or other ratingssystems. For example, KMC controllers, sensors, andsoftware can play key roles in satisfying the prerequi-sites and credits in the Energy and Atmosphere (con-stituting 25% of the total points) and Indoor Environ-mental Quality (22% of the total) categories for LEEDNew Construction and Major Renovation.

When attaining (the highest) LEED Platinum certica-tion, the Merry Lea Environmental Learning Centerof Goshen College had KMC direct digital controllers,sensors, and software working together to monitorand log building system performance factors such asheat pump uid temperatures, current generated byphotovoltaic arrays and a wind turbine (to get creditfrom the utility company), as well as other environmen-tal conditions.

When attaining the ENERGY STAR label, the WachoviaBank Building in Tampa Florida used software andover 300 BACnet controllers manufactured by KMCControls. The HVAC controls retrot, which replacedan obsolete system, provided an additional monthlyenergy savings of 10% over the previous system. In ad-dition to energy savings, it also included CO 2 monitorsto enhance the air quality and help meet qualicationsto pursue LEED Gold certication.

On the following two pages are visual examples ofKMCs controls used within different networks of alarge building automation system.

Higher Energy Efficiency Controllers optimize HVAC efficiency (by methods such as resettingsetpoints of boilers according to outside temperature, optimizing start/ stop times for occupied periods, using economizers for free cooling,and maintaining ventilation at the most efficient ow rates)

Motion sensors allow automatic setback override during unoccupiedperiods as well as adaptive occupancy scheduling

Lighting controls reduce unnecessary articial lighting via motion sen-sors and schedules and as well as (not shown) by controlling daylightharvesting louvers

Controllers save water and energy by controlling rainwater harvestingand landscape irrigation (not shown)

Lower Operating and Maintenance Costs Trends and logs provide information for further optimization of thesystem as well as for documentation requirements for building certi-cation

Individual room control allows setpoint adjustments only where needed Based on sensor data, software alarms and notications alert servicepersonnel to issues before they cause discomfort to building occu-pants and escalate into bigger, more costly problems

Remote network monitor, control, and troubleshooting via the Internetor modem reduces service calls

Sensors with data ports also allow quick network access and controlto service personnel using a laptop computer and a network interface

About KMC Controls and Additional Resources

KMC Controls, an ISO-9001 registered company, is theonly privately held manufacturer of a full line of HVACand building automation controls inthe USA. At KMC Controls, peopleand the planet matter, and in thelong-term, whats good for peopleand the planet prots everyone. Joinus in the sustainability revolution!

For more information about KMCControls, see our CorporateCapabilities Brochure (SB-052).

For denitions of green building terms,see our award-winning and very popularpocket-sized Green Building and ControlsGlossary (SB-046).

For the latest information aboutKMC Controls and sustainablebuildings as well as download-able PDFs of the mentioneddocuments, see the award-winning KMC Controls web site(www.kmccontrols.com).

For monitoring thermal comfort, air quality, lightingrequirements, and energy usage, the eyes and earsof controllers are switches and sensors that detecttemperature, humidity, pressure, air ow, CO 2, CO,smoke, occupancy, and electrical current. Actuators,valves, relays, and other outputdevices (not shown on the pre-vious spread) perform neces-sary electronic, electrical, andmechanical actions (as directedby the controllers). These actions controlthe ow of air or hot/chilled water or con-trol external electrical circuits such as forlighting, fans, pumps, compressors, boilers,and chillers. Other KMC tools include rout-ers, repeaters/isolators, surge suppressors, computerinterfaces, transformers, power supplies, enclosures.

For stand-alone applications and small buildings, aTier 2 network can sustain operations without a dedi-cated computer or LAN, but for networking capabilities,

controllers can be interconnected via economical wiring.When needed, technicians can use convenient on-sitenetwork connections or use dial-up modem connectionsto check status or change programming. Larger com-mercial building installations typically use networks ofTier 2 controllers within each zone and also intercon-nected zones of Tier 1 controllers. For campus-typeor geographically dispersed applications, Internetsolutions connect systems and workstations. Opera-tors can monitor and control the system with eitherbrowser-based or directly connected workstations.

For additional information about contacting a supplier,see the KMC Controls web site.

About BACnetBuilding automation controls are increasingly usingBACnet, the only communications protocol that wasdesigned for open-system interoperability and speci-cally intended for building systems. Interoperabilitymeans that products from different manufacturerscan communicate with each other and work together.The concept of interoperability blends well with theintegrated project design of LEED and other greenapproaches.

An open system helps reduce future risk. If a vendorfor an installed proprietary BAS goes out of business,future maintenance and upgrades might require theold BAS to be torn out and entirely replaced by some-thing new. Interoperability, however,means that new can build on old,helping future-proof life-cycle costs.
