Melbourne Cricket Ground

The Melbourne Cricket Ground (MCG) is Australia’s best known sporting facility. Founded on its current site in 1853, the ‘G’ has undergone many changes over the last 150 years, the most recent of which is the $430 Million Northern Stand redevelopment, which was finished on schedule in time for the hosting of the 2006 Commonwealth Games.

The Auto-Matrix System at the ‘G’ consists of over 560 Controllers and is responsible for the control and management of all of the Mechanical systems including:

  • Over Six Chillers and Boilers
  • Melbourne Cricket Club (MCC) & MCG Monday through Friday offices
  • 180+ Corporate Boxes
  • 16 Dining Rooms
  • 10 Bars
  • 157 Cool Rooms & Freezers

The Auto-Matrix System is trusted with the control of the Lighting System and the Monitors around the Grand Stand. Also entrusted is the monitoring and alarming of the Cool Rooms and Freezers that supply the 100,000 guests on match day with their food and drinks.

Interesting Fact: There are currently 55,000 Full Members, 34,000 Restricted Members and over 210,000 people on the waiting list to become members of the MCC (which equates to a 12 – 15 year wait for a Restricted Membership!)

A Smart Building Solution for Maximized School Comfort

Challenge

Pendergast Elementary School District (ESD), located in west Phoenix, Arizona, set out to decrease harmful emissions, as well as lower inflating operating costs. The climate in Arizona made this a challenge, as it is estimated that every summer, Arizona will have 30 or more consecutive days of temperatures over 110 degrees.

Knowing that HVAC accounts for nearly half the energy consumption for each building, key decision makers at Pendergast ESD began to determine how Building Automation Systems can maximize the efficiency of existing systems. The new BAS had to lower energy consumption, decrease harmful emissions, and help save critical funds with every utility bill.

 

Solution : AspectFT

Pendergast ESD turned to a local firm for their expertise. After working to identify the needs of the district and create a budget, it was determined that AspectFT, the Building Automation Integration and Energy Control Solution from American Auto-Matrix was an ideal application, and proposed a district-wide implementation.

Utilizing various digital control sequences, the American Auto-Matrix solution controls the HVAC equipment according to weather conditions as well as tenant-specified comfort levels. Along with controlling energy management functions, AspectFT provides diagnostic information based on factors relevant to energy consumption and generates reports usable by facilities management, the governing board, and others for tracking energy usage and the operational status of the system.

The DDC system uses fully-distributed intelligence for all control functions. Individual occupancy sensors disable lighting and cooling systems when rooms are not in use, and scheduled preconditioning ensures comfort for anticipated occupancy.

The AspectFT system uses technology including iCalendar for scheduling, RSS feeds and Twitter® for reporting and alarming, as well as other everyday technologies that make it easy for staff to utilize, as well as get the information needed to ensure energy management goals are on target. Buildings are now programmable and manageable by on-site facility staff, and accessible by web-enabled devices, giving the ability to control and diagnose what is going on in each building, down to each room.

 

Outcome

The implementation of AspectFT qualified Pendergast ESD to receive over $200,000 in energy reduction rebates from one of Arizona’s largest utility providers, APS. This rebate incentive substantially lowered the cost of implementation, and qualifies the district for continued cash-back opportunities.

City of St. Louis

A Smart Solution for City-wide Integration

 Challenge

The city of St. Louis, Missouri faced two major challenges when looking to upgrade the buildings that housed the city’s top officials.

The first was the severe climate that St. Louis faces throughout the year. Temperatures have been known to fluctuate double digits within a single day. The winters are brutally cold, with many days never getting out of the single digits. The summer months are equally harsh with extended periods often reaching over 100 degrees, coupled with high humidity. Comfort is hard to come by, but was much needed for the officials who ran the city.

The second was taking old and often failing systems individually installed in each building, and replacing them with a dependable, central system; encompassing ten buildings and thousands of points. The new building automation system also had to be durable enough to survive the harsh mechanical rooms of buildings that dated 50 to 100 years.

For this, Automation Solutions Group (ASG) was called upon to take on the challenge of providing a solution for the city which was reliable, easy to use, and achieved the comfort they were looking for.

 

Solution

ASG utilized American Auto-Matrix® products in ten buildings throughout the city which include City Hall, housing Mayor Francis Slay’s Office, the Mel Carnahan Courthouse, The Juvenile Detention Center, Civil Courts, City Hall West Bonds, St. Louis Streets Department, and three recreation centers.

 

Results

Concentrating on the ease of use and scope of the project, Automation Solutions Group and American Auto-Matrix worked together to implement AspectFT® throughout the buildings; tying everything together with one easy-to-use front end system.

With thousands of points through the various buildings, the system is using both PUP and BACnet® protocols and is controlling boilers, chillers, large air houses, rooftop units, and more.

The project utilized over 650 AAM controllers, 4 AspectFT-Nexus™, 1 MatrixPNC™, and 1 AspectFT-Enterprise™. ASG is also able to monitor equipment from other manufactures throughout the buildings using the AspectFT system.

There are plans for Automation Solutions Group to add two more buildings to the system, and hopes to control all of the city operated buildings over time.
