| Johnson Controls global headquarters holds bright prospects for LEED Platinum certification on expansion |
The 33-acre complex includes 306,359 square feet of new and completely renovated office space. Two existing buildings with a combined 160,000 square feet were renovated for the corporate headquarters, and three new buildings were constructed: a 114,599-square-foot headquarters for its Power Solutions business; a 31,700-square-foot building that includes a cafeteria, meeting rooms and fitness centre; and a new four-level parking structure for more than 400 vehicles including space for plug-in hybrids.
Years of green building experience
Johnson Controls is no newcomer to green. On top of more than a century of making buildings energy efficient, a decade ago its Brengel Technology Centre was one of the first LEED certified buildings in the world. It also was the very first building in the world to be re-certified LEED Gold-Existing Buildings.
"We have been involved in more than 100 of our customers' LEED-certified or registered projects around the world. We know what technologies provide the best financial investment while having the least impact on the environment, and at the same time create a productive workplace for employees," says Ward Komorowski, Johnson Controls director of facilities and building services.

"It's important that our employees, customers and the public understand every aspect of our commitment to the triple bottom line. The new corporate campus helps that happen," he says.
For instance, that means incorporating geothermal heat pumps, photovoltaic energy, under floor heating and cooling. Skylights and bigger windows increase the use of natural light and reduce dependence on artificial illumination. Rainwater is collected and used to flush toilets. A parking lot surfaced with permeable pavers allows rain and snowmelt to filter through. And a diverse workforce trained in sustainable construction helped put it all together in a cost-effective way.
Modelling from the start
For any green project, it's vital to get the entire project team on board from the beginning. "LEED encourages everyone to be involved much sooner in the process because there is so much interconnection between the different environmental credits," according to Komorowski.
He says early planning was especially important at this site because of the use of Building Information Modelling (BIM), which involves three-dimensional, building modelling software to provide exact design and construction measurements that are shared by all project members.
Using BIM made it a more cost-effective project because it helped avoid costly mistakes that can happen in traditional construction. BIM also provides:
- Financial security: The system's technical accuracy means precise measurement and fewer change orders. That certainty allows for more automation when fabricating materials, which also saves money. It also reduces the financial variables on a project, as all the details are worked out early.
- Condensed timetable: Because of the automation, contractors can do a tremendous amount of off-site work in clean, dry factory environments, which reduces weather-related delays while other work is done on-site.
- Project satisfaction: The 3-D modelling assures that the customer gets exactly what they want before construction begins. It's right there on the screen.
Technical innovation
Debbie Vander Heiden, the Johnson Controls on-site project manager, says other planning technology was crucial to one innovative environmental element of the project: geothermal heat pumps.

"The heat pumps reduce winter heating costs by about 29 percent versus current natural gas boilers. We are using geothermal to remove condenser heat in summer and reduce chiller operating costs by 23 percent," says Vander Heiden.
By using global positioning system navigation, the team could determine every geothermal well site along with the measurements for all the pipes. That meant the 180,000 feet of piping could be manufactured to precise specifications, a simpler and more cost-effective process than fabricating each one by hand.
Long-term energy costs key
Although sometimes concerns are voiced about the upfront cost of green projects, the financial benefits on this project are proof of sustainability's value. While overall campus space will almost double, the company expects a minimal increase in energy costs.
- Solar generation supplements electricity needs while reducing greenhouse gas emissions by 1.1 million pounds per year for the campus. A 1,330-square-foot solar thermal installation on the roof annually saves 2,837 therms of energy.
- Skylights and increased window space reduce the use of energy for indoor lighting.
- A 30,000-gallon cistern captures rainwater from roof surfaces on new buildings for reuse, reducing potable water consumption for new bathroom fixtures by 77 percent or 595,000 gallons.
- A number of on-site recycling strategies are saving money and resources. Almost 90 percent of new construction waste and more than 75 percent of demolition waste from existing buildings was recycled.
Commitment to supplier diversity
The project includes contracts with 35 diverse businesses in an effort to help the suppliers create green jobs, build expertise in sustainability, and develop the capacity to handle other major green contracts. The $18.5 million in expenditures exceeded the company's goal of spending at least 20 percent of its budget with firms that were owned, operated or controlled by minorities or women and certified either by the National Minority Supplier Development Council (NMSDC) or the Women's Business Enterprise National Council (WBENC).
The diverse suppliers provided products and services such as:
- Site electrical services
- Green landscape services
- Low-voltage cable installation
- Aluminium glazing
- Deck installation
- Steel fabrication
- Liner installation and stone for pervious lots
"The contracters and subcontracters on the job were trained in sustainability practices that they can use with other LEED jobs. We are creating the green collar workforce of tomorrow," Komorowski says.
The project also provided economic development by using locally harvested and manufactured materials for more than 25 percent of project materials, including the raised floor, concrete, steel and limestone.
"We have learned the best practices for developing green projects, making best use of contracters, and managing the process," he says. "These are lessons we are sharing with our partners on this project - and down the line, our customers and many others will benefit from our experience."
Security management
Vander Heiden notes that even the security features at the headquarters were developed with energy savings in mind.
The Johnson Controls P2000 security management system and Digital Vision Network provide protection throughout the headquarters campus. It's designed to use energy efficiently by integrating access control with lighting and HVAC systems.
Additionally, digital closed circuit TV cameras across the campus take advantage of advanced analytics to notify facilities operators of abnormal events, plus some 150 card access and biometric readers provide a high level of protection. A Johnson Controls Intelligent Fire Control system features full analogue reporting from smoke detectors, along with digital voice evacuation functionality. Infrared camera technology is used at the solar array field to create an "electronic fence".
Building automation
Everything is tied together using the Johnson Controls Metasys® building management system to coordinate all activities across the facilities and provide a single point of access to performance indicators - the information required for optimising building efficiency, comfort and safety.

"The integration of the building systems and the information technology infrastructure into one intelligent network is an important part of our strategy for sustainability," notes Komorowski, who leads the facilities management team. "Our Metasys Sustainability Manager provides a dashboard that delivers information, including greenhouse gas emissions estimations, to our management team who can make informed decisions that save energy and money and help the environment."
Powerful statement
Johnson Controls is preparing for thousands of people to visit this site in the coming years to see how the company is brimming with innovation and sustainable technology.
"It will be easier for our own customers to see value in this approach, when we can show how well we are putting it into effect here at home - and how we are doing it cost effectively," Komorowski says.
"This campus is a powerful statement about how Johnson Controls is committed to sustainability. It's a showplace of excellent work environments, energy efficiency and facility management initiatives," he adds. "We are looking forward to accommodating many years of business and employee growth."
The company began demolition in Fall 2007, and had a grand opening in Fall 2009. The campus is a continuation of Johnson Controls legacy that began in 1885. Its three global businesses - Automotive Experience, Building Efficiency and Power Solutions - continue to drive toward its mission of delivering a more comfortable, safe and sustainable world.
