A New Energy Management System
for the Next Era in Building Automation & Control
Greg Shank,
Altura Associates


A single, integrated engineering team should collaborate on all software programming and optimization tasks - controls, analytics, and workflow management - during design and construction. The resulting data platform can evolve into a building energy management system that will serve the building’s on-going commissioning needs through its useful life.

In the new data-driven life cycle of modern commercial buildings, building automation and controls services can be an effective bridge between design, construction, and operation. Gone are the days when building controls functionality was locked within a construction subcontract and squeezed into the chaotic final days of construction and initial occupancy. Open network architecture and employment of a connected building commissioning (CBCx) approach have opened a new landscape.

Today, optimal operating sequences and relationships can be built into the “smarts” of a building, and performance requirements can be made software-enforceable. However, these software aspects need to be considered early and repeatedly throughout the design/construction cycle by a multi-disciplinary project team. In effect, the team is defining a software data platform that will extend into the normal operations phases of the building’s life.  Done correctly, it will serve as the building’s next-generation Energy Management System (EMS) and will adapt to the needs of the owner and occupants over time without costly hardware changes or massive software overhauls. It will put the most useful and valuable information at the fingertips of the building managers and operators and empower occupants and the facilities staff to get the most out of their building.
The path to this vision for a next-generation Energy Management System does require new approaches to project delivery for both new construction and retrofits. According to Smart Building Research firm Memoori, the traditional supply chain for building automation system (BAS) services is in the midst of a major restructuring. The critical piece of this restructuring is the separation of the contracts for hardware installation from the contracts for software, including controls, analytics, and workflow management.

This separation enables building owners to take advantage of the explosion in software services that mine building data to reduce energy costs, improve occupant comfort, streamline operations workflow, and automate corporate environmental reporting. No single company or product category can drive the full potential of this industry shift. Instead, it will be built on top of open network architectures, where a variety of innovative service providers can easily leverage the data from the myriad connected devices throughout a building.

When taking our clients through this process, they often initially respond, “This sounds great, but are you telling me I now have to manage even more subcontracts and spend more money?” I’m happy to report that the answer is “No.” Altura has facilitated and executed a range of strategies to control complexity and costs as you progress toward this new EMS vision.  Here are a few of our key recommendations:

Reliable Controls A common theme in these recommendations is the need for simple and continuous lines of accountability. For example, the simple step of separating controls hardware procurement from the software programming, optimization, and maintenance creates powerful opportunities, but these opportunities can be destroyed if the responsibilities are handed off between parties throughout the process. For example, we have a project transitioning from construction to occupancy right now where Altura is responsible for commissioning of the building systems, building the controls programming, integrating HVAC controls with lighting, security, and windows, and building the energy management dashboard for the owner. While it has been a challenge to play this unique role with the various subcontractors and manufacturers on the project, we are driving a level of integration and performance that is a complete game changer for the owner/developer.
