Buildings get efficient with data-driven solutions
INDUSTRY : Industrial Products


A specialty manufacturer of high-performance pressure independent control valves for industrial applications created a subsidiary to focus on creating innovative solutions for energy-efficient, cost-effective and comfortable buildings. The spinoff, which functions as a start-up company, incorporates these valves into heating, ventilation and air conditioning (HVAC) systems to allow for a more intelligent method of controlling the climate in individual rooms, buildings and office parks. By considering each element of an energy ecosystem and how they work together, the new company focuses on next-generation solutions, harnessing the power of the Internet of Things (IoT) as it defines a strategy for its clients to help identify and manage energy risks and opportunities so they can improve the bottom line.

IoT technologies are dramatically changing the way computing is woven into everyday business operations.


The company’s founders began with a vision to leverage their hardware breakthroughs to provide precision control of commercial heating and air conditioning systems. HVAC systems are important in the design of medium and large industrial and office buildings to ensure safe, healthy and comfortable building conditions and to allow them to operate at peak efficiency. A large office park or university setting can consist of hundreds or thousands of HVAC units managed by a variety of systems. Maximizing the efficiency of these systems can result in a considerable savings for an organization – industry estimates are that HVAC systems account for 35 percent of energy used in manufacturing facilities4 and 40 percent of commercial building energy consumption worldwide.5

The client was driven to help organizations better manage costs related to commercial heating and air conditioning control systems. Statistical analysis of data collected via climate-control systems and existing building automation systems affords the opportunity to more precisely control the climate of a building or group of buildings. This level of control allows senior management to determine where energy is being used – and, correspondingly, where money is being spent. It allows building operators to better manage the climate in individual rooms, buildings or campuses. Precise control also reduces the resources needed for troubleshooting and addressing problems with the HVAC system due to central control of the systems and the ability to better pinpoint issues with the system.

To address these challenges, the new company needed to create a proof of concept for its vision, define the minimum viable product, then develop the first production product, so its executives decided to tap into PK’s expertise to reach these milestones.


Through its partnership with PK, the client was able to bring its ideas into fruition and help building management and owners meet today’s rapidly evolving energy challenges via a data-driven solution.

Because the client needed a way to communicate value, collect data and control a distributed hardware network remotely, PK helped create a streamlined data-driven solution that allowed it to collect the information required, display the correct information to the clients who owned the data and give engineers access to devices from a central location.

Throughout the development of the proof of concept, then the product, the PK team utilized an Agile development methodology to achieve quick turnaround during continuous development, both taking into account feedback from the client and also from its first customer, a Midwestern university, once the initial production run was underway. The solution, which utilized relational databases, sensors and Linux boxes that reported to the database using a web API, was built on a Windows server using .NET, Java, Python (for the embedded systems), SQL Server 2008 and iOS.

The end solution included an extensive feature set that allowed multiple consumers to benefit. C-level executives could view information about the building at the campus or building level to determine where money was being spent on energy use. Because the data-driven solution worked with existing building-operation systems, building operators could log in to the app to better control building climates, choosing when to override the existing automated controls and responding to occupant comfort. A field engineer suite allowed technicians to monitor, analyze and update the control system, and enabled remote management and firmware updates for the system hardware—reducing the time and resources needed to send engineers out to examine individual connections for problems. PK also created an app that allowed technicians to scan a Quick Response (QR) code to quickly identify a piece of equipment and the associated information.

By working with the client from ideation to production over the seven-month engagement, PK was able to develop a state-of-the-art holistic architecture that allowed for rapid market expansion of the client’s product to new customers and partners. These customers, in turn, were empowered with the tools and data they needed to optimize their controls, saving money and reducing energy use.
