Systems engineering is a holistic approach that considers the entire lifecycle of a system, from design to disposal. By taking a systems engineering approach, organizations can reduce waste and minimize environmental impact.
Effective systems engineering involves identifying and mitigating potential risks and inefficiencies early on. This can be achieved through the use of modeling and simulation tools, which can help predict and prevent problems before they occur.
A well-designed systems engineering process can lead to significant cost savings and improved efficiency. For example, a study found that the use of systems engineering principles in the design of a new factory resulted in a 25% reduction in construction costs.
By applying systems engineering principles to building design and operation, we can create more sustainable and efficient buildings that meet the needs of occupants while minimizing environmental impact.

Why Building Matters
Building systems are a crucial aspect of reducing energy consumption in buildings, as they account for almost 40% of primary energy use in the U.S. and globally.
The buildings sector is a significant contributor to energy consumption, and significant energy efficiency gains have been made through policies and programs that focus on individual building components or whole buildings.
However, building energy consumption continues to rise globally due to growing floor space and increasing electricity demand from new devices and equipment, including plug loads/miscellaneous electric loads.
To achieve the next level of efficiency, a systems approach is required, considering interactions among building components, multiple buildings, and between buildings and the electric grid.
A systems-efficient building is one in which multiple building systems are designed, installed, and operated to optimize performance collectively to provide a high level of service or functionality for a given level of energy use or input.
Here are the key strategies for building systems efficiency:
- Breaking down silos: Collaboration across stakeholders, including architects, engineers, designers, developers, and building operators, is essential.
- Integrating systems: Integration within and among systems operating in a building is vital to maximizing efficiency gains and opportunities.
- Optimizing operations through technology: Controls and smart technologies are important for improving the efficiency of many types of systems.
- Incorporating systems strategies: Strategies to incorporate a systems approach should be applied during building design and construction, as well as during the operations and maintenance phases.
- Thinking outside the building: Opportunities for systems approaches exist beyond a building itself, across multiple buildings and between a building and the electric grid.
Designing for Efficiency
Engineers can advise architects and developers on designing commercial buildings that are more efficient. Selecting materials that minimize thermal gain or loss is an important factor in deep retrofits on buildings.

By incorporating natural ventilation or maximizing daylighting, buildings can reduce their reliance on mechanical systems for temperature regulation. This approach saves time and money down the line.
A residential building's HVAC operational effect can be modeled and simulated using Model-Based Systems Engineering. This approach allows for easy requirements verification and validation while creating a truly optimized system.
The EIA estimates that building energy consumption could be reduced by 10%-18.5% within the residential and commercial sectors by 2035. Reducing building energy demand is a necessary step in curbing the greenhouse gas issue.
The parameter of insulation R-Value has the greatest cost-to-efficiency benefit, while window U-Value has the second most impact on energy efficiency. This is according to a study that used trade-off analysis to optimize cost and energy efficiency.
