Comfort Mood: Making MEP Central to Occupant Comfort

In many post-COVID-19 projects, occupant comfort has transitioned from a “nice to have” to a “must have.” It’s infused into collaborations from the earliest phases of design and preconstruction.

That puts mechanical, electrical and plumbing (MEP) front and center. MEP contractors deliver the essentials of a comfortable experience. Whether they are controlling temperature, air quality, acoustics, lighting or water pressure, they impact the building’s livability and the well-being of its occupants. 

This article explores the rise of occupant comfort and MEP contributions, project-specific considerations, integrating smart technology and leveraging occupant comfort for competitive advantage. 

Dialing Up Occupant Comfort

Project owners are prioritizing occupant comfort in building construction. Human-centric design exceeds codes in its drive toward sanitary, habitable spaces where people breathe with confidence, gather without fear and bring their best selves to work or play.

Fortunately, occupant comfort can easily align with sustainability and operational efficiency goals for seamless integration into the top priorities of today’s sophisticated construction projects.

Key MEP Factors in Building for Comfort

Operating out of sight, earshot and mind, each MEP factor contributes to the finished building’s comfortable and welcoming experience.

Mechanical

Encompassing temperature, humidity and ventilation, it's the job of mechanical contractors to make sure all the rooms and zones in a building lack cold or hot extremes. They help manage humidity and — depending on geography — prevent mold growth. 

They are central to the vital concept of indoor air quality, to prevent the transmission of diseases and toxic particles. 

Mechanical contractors also manage acoustic comfort. By insulating and isolating ductwork, process piping and equipment rooms to dampen rumble and rattle, they lessen noise that can distract people from their work or rest.

Electrical

Proper lighting levels encourage efficiency and reduce stress. The right designs reduce glare and, depending on the project, maximize natural light to calm the atmosphere. 

Electrical contractors are also central to power reliability, preventing fluctuations and power losses that disrupt occupants’ days. 

Plumbing

Clean, safe, potable water is essential to every project. Appropriate temperature controls promote comfort, safety and sanitation. Correct pressure delivers a steady supply of water while also preventing the damage and consequences of backflow.

Like their HVAC colleagues, plumbing contractors can enhance occupant comfort by controlling any noise and “water hammer” knocking from their pipes and installations. 

Building-Specific Comfort

Different projects present different demands for occupant comfort.

• ---

  Healthcare

  In health systems, indoor air quality and infection control are paramount for the well-being of patients, staff and visitors. Rooms might be positively pressurized to protect surgery patients from airborne contaminants or negatively pressurized to withdraw contaminants. 

• ---

  Data Centers

  In structures housing thousands of servers, equipment needs outrank human comfort. Precise cooling prevents overheating, for optimal efficiency and performance. As mission-critical facilities, data centers, like hospitals, need unerring power reliability and redundancy.

• ---

  Offices & Institutions

  Office buildings, universities, hotels and sports facilities rely on MEP for thermal comfort as well as pleasing aesthetics. Venues and gathering rooms require flexibility that accommodates varying occupancies. 

Planning and Design Collaboration

Early integration with the building information modeling (BIM) team eases occupant-comfort principles into planning and design. Because occupant comfort is highly dependent on intricate details, this is the place for MEP contractors and all stakeholders to agree on the model’s level of design. 

From there, coordination determines execution among the trades as the schedule unfolds. Essential elements at this phase are clash detection and federated models to identify issues early, all delivered on a cloud-based collaboration platform that’s updated in real time. 

Smart Technologies and IoT Integration

Advanced technology has given rise to the intricate systems delivering true occupant comfort. The internet of things (IoT) and smart controls essential to building operations are embedded into the design from the beginning.

In this atmosphere, MEP contractors are inserting elements into an interconnected, responsive building. Their collaborative relationships with controls-systems contractors go smoothly with clearly delineated scopes — maybe assigning mechanical contractors to install pressure differential sensors as part of their oversight of inline devices, while controls contractors manage exterior installations.

When the building is operating, real-time monitoring will provide continuous feedback that feeds into AI and machine learning for predictive maintenance. These systems minimize downtime and create self-optimizing buildings that automatically adjust heating, cooling, lighting and plumbing based on trends in occupant behavior and demands on the spaces. 

And on the horizon: Personalized comfort controls at individual workstations or zones, where HVAC, especially, is tethered to IoT for automatic adjustments.

Building for Comfort: The Impact on MEP Contractors

Given the demands of occupant comfort, MEP contractors play key roles in helping engineers optimize designs, sizing and layouts based on performance and comfort parameters. 

As comfort grows more granular, MEP teams will need the expertise and enhanced skills to install increasingly complex systems. MEP contractors striving to keep pace should remain adaptable and present themselves as problem solvers with expertise in the growing field of occupant comfort.

MEP contractors who properly execute strategies to upskill their teams and create a culture of collaboration can gain a competitive edge in a world where every project rests on energy efficiency, smart systems and better occupant comfort.
