Indoor air quality in schools directly impacts the health, comfort, and performance of students and staff. Poor indoor air quality (IAQ) is more than just an inconvenience—it can contribute to a range of health issues, from allergies and respiratory problems to fatigue and difficulty concentrating. According to the Environmental Protection Agency (EPA), indoor air pollution consistently ranks among the top five environmental risks to public health. This makes HVAC systems for schools a crucial component in maintaining a healthy learning environment.

Why Indoor Air Quality Matters in Schools

Children breathe in more air per pound of body weight than adults, making them more vulnerable to airborne pollutants. Schools often house hundreds or even thousands of students, teachers, and staff, all of whom rely on a clean and well-ventilated environment to stay focused and healthy. 

Poor indoor air quality in schools can lead to:

• Increased asthma and allergy flare-ups
• Higher absenteeism rates
• Reduced concentration and learning capacity
• Greater risk of respiratory infections
• General discomfort such as headaches, fatigue, and irritation of the eyes, nose, and throat

The HVAC System’s Role In Indoor Air Quality In Schools

An effective heating, ventilation, and air conditioning (HVAC) system is the first line of defense in maintaining good indoor air quality in schools. 

The primary functions of an HVAC system include:

• Ventilation: Bringing in fresh outdoor air and removing stale indoor air
• Filtration: Capturing airborne pollutants, including dust, mold spores, and allergens
• Temperature Control: Maintaining comfortable and consistent indoor temperatures
• Humidity Regulation: Preventing mold growth and excessive dryness

A well-maintained HVAC system ensures that air is continuously cycled and filtered, preventing the buildup of contaminants that can impact student health and performance.

Key Strategies for Improving Indoor Air Quality In Schools Through HVAC Systems

Regular HVAC Maintenance and Inspections

Routine HVAC maintenance is essential for keeping air quality at optimal levels. This includes:

• Cleaning and replacing air filters regularly to remove dust, pollen, and bacteria
• Inspecting and maintaining ventilation ducts to prevent blockages and mold buildup
• Ensuring heating and cooling systems operate efficiently to maintain proper air circulation

Action Tip for Schools: Establish a preventative maintenance plan with scheduled HVAC inspections and filter replacements to prevent air quality issues before they arise.

Enhancing Ventilation

Proper ventilation dilutes indoor air pollutants and provides a steady flow of fresh air. Schools can enhance ventilation by:

• Using mechanical ventilation systems that meet ASHRAE Standard 62.1, which sets the minimum ventilation rates for acceptable indoor air quality in schools
• Installing energy recovery ventilators (ERVs) to improve air exchange while reducing energy costs
• Opening windows and doors when outdoor air conditions permit to increase airflow

Action Tip for Schools: Evaluate classroom ventilation rates and consider upgrading systems to meet modern ventilation standards.

Upgrading to High-Efficiency Air Filtration

Air filtration plays a crucial role in removing harmful particles from the air. Many school HVAC systems still use outdated filters that do little to improve IAQ. Upgrading to high-efficiency particulate air (HEPA) filters or MERV 13-rated filters can significantly reduce airborne contaminants.

Action Tip for Schools: Review HVAC filter ratings and invest in high-quality filters that capture smaller airborne particles for improved air quality.

Managing Humidity Levels

Excess humidity can lead to mold growth, while low humidity can cause respiratory discomfort. Schools should aim to keep indoor humidity levels between 30-50% to prevent these issues.

Ways to regulate humidity:

• Use dehumidifiers in humid climates to prevent mold
• Utilize humidifiers in dry climates to maintain comfort
• Monitor humidity levels regularly with indoor air quality sensors

Action Tip for Schools: Incorporate humidity sensors into the HVAC system to maintain optimal levels year-round.

Using Smart IAQ Monitoring Tools

Advancements in technology have made it easier to track and improve indoor air quality in schools in real-time. 

Schools can use wireless IAQ monitors to detect issues such as:

• High levels of carbon dioxide (CO2), which can cause drowsiness and reduced cognitive function
• Elevated particulate matter (PM2.5) from dust, pollen, or pollution
• High volatile organic compounds (VOCs) from cleaning supplies or building materials

Action Tip for Schools: Implement IAQ monitoring devices in classrooms and shared spaces to track air quality and adjust ventilation as needed.

Addressing IAQ Concerns in Older School Buildings

Many schools, especially older buildings, were not designed with modern IAQ standards in mind. Outdated HVAC systems, poor insulation, and aging infrastructure can contribute to indoor air pollution. To improve indoor air quality in schools in these settings, schools should:

• Upgrade old HVAC systems to meet current ventilation and filtration standards
• Seal leaks and gaps in the building envelope to prevent outdoor pollutants from entering
• Use portable air purifiers in classrooms where HVAC improvements are not immediately possible

Indoor Air Quality for a Healthy Learning Environment

A well-functioning HVAC system is critical in controlling pollutants, regulating temperature, and ensuring adequate ventilation. By prioritizing regular maintenance, upgrading filtration, and improving ventilation, schools can create a safe and comfortable environment for students and staff.

For school administrators and parents looking to improve indoor air quality in schools, investing in modern HVAC solutions and proactive maintenance plans is the best place to start. A commitment to cleaner indoor air today means a healthier, more productive learning environment for generations to come.

Conveyor belts are the backbone of many agricultural and industrial operations. Whether moving grain in an agricultural facility or transporting materials in a manufacturing plant, a well-functioning conveyor system is essential to keeping business operations running smoothly. However, just like any mechanical system, conveyors are prone to wear and tear. A broken conveyor can result in costly downtime, strained client relationships, and increased labor costs. That’s why regular conveyor belt repair, maintenance, and custom fabrication solutions are crucial to extending the lifespan of your equipment and keeping operations efficient.

Understanding Conveyor Belt Life Expectancy

Every conveyor belt is different, and its lifespan depends on several factors: frequency of use, the type of materials it handles, environmental conditions, and maintenance practices. If your belts are failing prematurely, there may be underlying issues such as misalignment, improper installation, or worn-out rollers. Identifying and addressing these issues early can save money and prevent operational disruptions.

Regular Conveyor Belt Maintenance: Prevent Problems Before They Start

Scheduled maintenance is one of the most effective ways to avoid unexpected breakdowns and extend the life of your conveyor belt. Here are some key maintenance practices that will help keep your conveyor system in top shape and prevent the need for costly conveyor belt repairs:

• Inspect Rollers and Bearings Regularly: Worn-out rollers can cause uneven belt wear and premature failure. If a roller is damaged, it should be replaced immediately to prevent additional stress on the belt.
• Keep the Belt Properly Tensioned: Improper tensioning can lead to belt slippage or excessive strain, causing unnecessary wear. Adjust tension as needed to maintain proper performance.
• Tracking Adjustments: Misaligned belts lead to uneven wear and potential damage. Regularly check and adjust belt tracking to ensure smooth operation.
• Lubrication and Cleaning: Dust, dirt, and debris buildup can significantly impact performance. Keep components clean and lubricated to reduce friction and prevent overheating.

Tessiers Successfully Installed 22 RTU Units with a Helicopter!

Recently, our Tessiers team was tasked with the safe and efficient installation of 22 RTU units, weighing between 650 and 2500 pounds, on a 330,000 square warehouse, located in Sioux Falls, SD. Our initial obstacles were identified: 150-foot reach from the building’s edge, and units spanning roughly 450 feet east to west and 250 feet north to south, and 42-foot-high walls.

Typically, such installations would involve the use of a crane. However, our experienced preconstruction team determined that using a rotorcraft would be more effective.

Safety was our top priority. Working alongside one another, the Operations Manager, Safety Director, Foreman, and Project Manager noted that the parapet wall was less than 42 inches and identified rooftop openings with drops exceeding 6 feet. To avoid potential falls and safely navigate across the rooftop we determined the best application for this task would be using two mobile fall protection devices (raptor carts).

Our foreman Robert Burns, noticed each cart would require a team of four, North Team and South two members to move the cart and two to place each unit and disassemble the rigging. The roof top navigation plan was put on paper.

The night prior to the pick, a plan pre-task session was conducted by Tessiers with the GC, and all operation leaders. Tessiers ensured our safety plan would be enforced, and the job site was prepped, and all hazards have been addressed. We discussed procedures and identified additional hazards. The signalers played crucial roles in directing the helicopter and providing communication with the pilot and our team members.

Having identified potential hazards and implemented safety measures, we proceeded with the pick plan early the next morning. Tessiers took control

of the job site, blocking access to the building, setting up extraction points, distributing personal protective equipment (PPE), and staging the units. A final review of the pick plan was conducted with the collective staff.

As an audience gathered outside the protected zone, our plan was implemented. Our rooftop team efficiently moved across the building while the ground team prepared for the next pick. Each member was vital to ensure the operation was completed seamlessly. We were able to set each unit in under three minutes.

Addressing all aspects of safety, communication and preplanning by our team made this task a success.

As a commercial property manager, you know how important it is to keep tenants and guests comfortable. Balancing heating and cooling can be tricky, especially with varying needs across different areas of a building. Factors like the number of occupants, heat from equipment, and insulation levels all affect how your HVAC system performs. It’s not just about setting a temperature; it’s about managing different needs and ensuring consistent comfort throughout the building. Efficient climate control is crucial for maintaining satisfaction and attracting tenants, making it essential to address these challenges effectively.

HVAC system zoning can help by dividing your building into different areas, each with temperature controls. This allows for more precise climate management, improves comfort, and can even reduce energy costs. For instance, the upper floors of an office building might need cooling while the lower floors stay warmer, and a computer lab may require extra cooling. Zoning helps ensure each area gets the exact temperature it needs.

How HVAC System Zoning Works

An HVAC zone control system uses thermostats, a central control panel, and zone dampers installed in the ductwork. Each zone has a thermostat that communicates with the control panel, which adjusts the dampers to regulate airflow. This setup allows each zone to control heating and cooling independently without affecting others. 

Commercial HVAC companies insert dampers into the ductwork to enable HVAC system zoning. These dampers isolate various parts of the building so that conditioned air cannot enter them. A satellite thermostat is included in each zone to adjust the local temperature without affecting the temperature elsewhere. 

For example, a zone with many computers requiring extra cooling will not influence the temperature in adjacent zones. This system is efficient, especially in buildings with varying temperature needs, as it targets only the areas in use, optimizing comfort and reducing energy consumption.

 Elements for HVAC System Zoning 

• Zone Dampers: Installed in the ductwork, these dampers open or close to direct airflow to specific zones, enhancing energy efficiency and temperature control.
• Thermostats: Each zone has a separate thermostat to monitor temperature and send data to the control panel, which adjusts the dampers and HVAC equipment accordingly.
• Control Panel: This is the system’s central unit, processing thermostat data to manage dampers and equipment, often with digital interfaces for setting preferences and schedules.
• Ductwork Modifications: Installing zoning may require changes to the ductwork, including additional dampers and bypass ducts for balanced airflow.
• Damper Actuators: These mechanisms control the dampers based on signals from the control panel, enabling precise temperature regulation.

Benefits of HVAC System Zoning

The benefits of a well-designed HVAC zoning system include focused, consistent heating and cooling, customized temperature control for better employee comfort, and significant energy and cost savings. Adjusting heating and cooling based on each zone’s specific needs can reduce energy waste and potentially lower costs by up to 25 percent.

• Energy Efficiency: HVAC System zoning allows you to heat or cool only the areas that need it, reducing energy consumption and lowering utility bills, especially in rooms that are not frequently used.
• Longer Equipment Lifespan: By preventing your HVAC system from working harder than necessary, zoning reduces wear and tear on the equipment, extending its life.
• Reduced Temperature Swings: Zoning eliminates large temperature fluctuations when a single system tries to balance multiple needs simultaneously.
• Targeted Temperatures: Zoning enables precise temperature control for different areas, such as providing extra cooling for heat-generating equipment without affecting other parts of the building.
• Increased Comfort: Personalized climate control means everyone can enjoy their preferred temperature, enhancing overall comfort.
• Improved Property Values: Modern zoning systems add appeal to your property, making it more attractive to potential buyers or tenants due to the enhanced comfort and energy efficiency they offer.

Considerations When Planning a Commercial Zoning System

Careful planning and design are essential to maximizing the benefits of a commercial HVAC zoning system. Keep individual zones manageable—ideally, no larger than a single floor or a few rooms. Zoning systems are less effective in open spaces or areas with frequent temperature changes, like warehouses or spaces with open doors. Place thermostats in each zone’s most frequently used room to ensure accurate temperature control. Group rooms with similar energy efficiency features and thermal characteristics within the same zone for optimal HVAC performance.

While a zoning system offers many benefits, there are some potential drawbacks. One is the higher initial cost of installation compared to traditional HVAC systems. Setting up an HVAC zoning system can also be more complex, often requiring professional expertise and additional installation steps. Regular upkeep is important to address any issues that may arise, and it’s best to work with experienced technicians to keep the system running smoothly.

Adding HVAC System Zoning To An Existing System

Before considering HVAC system zoning, evaluate your existing system’s readiness. Ensure your HVAC equipment is modern and robust enough to handle zoning, and check if your ductwork can accommodate it with minimal modifications. An HVAC specialist can evaluate your setup and recommend a suitable zoning plan based on your building’s layout, sun exposure, and usage. Installation typically involves adding zone dampers to direct airflow, equipping each zone with a thermostat, upgrading the central control panel, and fine-tuning the system to ensure proper operation.

For property managers, weighing the investment against potential returns is essential. While zoning can improve energy efficiency and tenant satisfaction, it also involves initial costs and possible disruptions. Plan for downtime during installation and be prepared for increased maintenance needs due to the added complexity. Working closely with HVAC professionals will help ensure that HVAC system zoning enhances your system’s performance and aligns with your property’s needs.
