Want SMARTER AEC Projects? Building Enclosure Commissioning and AI Can Help!

Key Concepts

• Building Performance: Ensuring buildings meet design expectations for structural integrity, thermal efficiency, air leakage, water penetration, and MEP systems.
• Commissioning: A documented process to bring a building into working order, starting from pre-design through operations, involving owner requirements, design feedback, construction verification, and testing.
• Building Enclosure: The physical separator between the interior and exterior environments of a building, including walls, roofs, windows, and foundations.
• Quantified Building Performance: Using data and testing to verify and optimize building performance in various aspects.
• AI in AEC: Utilizing artificial intelligence to improve efficiency, coordination, and decision-making in the architecture, engineering, and construction industry.
• Forensic Engineering: Investigating existing building conditions to understand performance, failures, and inform renovation or retrofit projects.

Challenges in Translating Design to Reality

• Bridging the Gap: The primary challenge is ensuring that a building's actual performance aligns with its design intent.
• Collaboration: The heart of ensuring building performance lies in human collaboration throughout the entire process, from initial design to construction and operation.
• Verification: Rigorous testing and verification are crucial to confirm that materials and systems are installed correctly and meet performance standards.
• Evolving Performance Aspects: Building performance now encompasses more than just structural integrity, including thermal efficiency, air leakage, water penetration, and MEP systems.

Building Commissioning: A Detailed Process

• Definition: Commissioning is a process to bring a building into working order, ensuring it meets the owner's requirements.
• Historical Context: Commissioning originated in maritime and aviation industries, where safety was paramount, before being adopted by the building industry in the late 1980s and early 1990s.
• Owner's Project Requirements (OPR): The process starts with defining the owner's needs and expectations for the building's performance.
• Design Phase: Develop a test plan to verify building performance, focusing on critical transitions like window-to-wall, wall-to-roof, and wall-to-below-grade.
• Testing Methods: Utilize various ASTM standards and tests to verify water penetration resistance, air tightness, and thermal performance. Examples include infrared scans to verify roof watertightness.
• Example: For a renovation project at Penn State, the owner specified air tightness requirements to improve energy efficiency and indoor air quality, and to protect the structure from condensation and mold.
• Factors Influencing Commissioning: Owner's requirements, risk appetite, and budget all influence the scope and intensity of the commissioning process.

Emerging Technologies: AI and Their Impact

• AI Task Force: Ishkenir's company has formed an AI task force to explore and implement AI solutions to improve workflows.
• Efficiency Gains: AI is expected to drive significant efficiencies in the construction process, from design to operations.
• Coordination: AI can improve coordination between different teams and stakeholders involved in a project.
• Repetitive Tasks: AI can automate repetitive tasks, freeing up engineers and architects to focus on more complex and creative work.
• Experimentation: Companies should experiment with AI tools to identify specific pain points and develop tailored solutions.
• Enterprise vs. Individual Productivity: There's a difference between individual productivity gains and enterprise-wide improvements, which require training and strategic implementation.
• Addressing Pushback: Encourage hesitant individuals to try AI tools to overcome initial resistance.
• Use Cases: AI is well-suited for text-based tasks like report generation, specification writing, and email management.
• Business Model Implications: AI may change traditional billing models, shifting from hourly rates to value-based pricing.
• Recruiting Advantage: Companies that embrace AI and train their employees will have a recruiting advantage.

Engineering for Existing Buildings vs. New Construction

• Forensic Approach: Renovation projects require a forensic approach to understand existing conditions and performance.
• Existing Drawings: Existing drawings are often inaccurate, necessitating on-site investigation to determine actual conditions.
• Change of Use: Changing the use of a building, such as converting a parking garage to residential, requires structural analysis to accommodate different loading scenarios.
• HVAC Systems: Understanding how HVAC systems interact with existing conditions is crucial for enclosure consulting.
• Underappreciated Space: The existing structure restoration and forensics world is often underappreciated compared to new construction.
• Learning from Failures: Investigating existing buildings provides valuable insights into what works and what doesn't, informing better design and construction practices.
• Smaller Pond: The restoration space offers opportunities to develop internal solutions or partner with startups.

Advice for Young Professionals

• Embrace Discomfort: Put yourself in uncomfortable situations to foster growth and learning.
• Ask Questions: Don't hesitate to ask questions in meetings, even if you feel unsure.
• Assert Yourself: Be confident and assertive in your ideas and opinions.
• Emotional Quotient (EQ): Develop strong communication and human coordination skills.
• Technical Writing: Improve technical writing skills to effectively convey your message.
• Irreplaceable Skills: Focus on developing skills that are not easily replaced by technology.

Conclusion

The discussion highlights the critical importance of collaboration, verification, and continuous improvement in the AEC industry. Emerging technologies like AI offer significant opportunities to enhance efficiency and coordination, but strategic implementation and a focus on human skills remain essential. By embracing discomfort, asking questions, and developing strong communication skills, young professionals can navigate the changing landscape and contribute to creating durable, high-performing buildings.
