Managing Indoor Air Quality

Clean air is a safety concern.

For building owners and managers, ensuring tenant and visitor welfare is always of paramount importance. And while there is only so much that can be done to control the quality of the air that enters into a building, it is still important to frequently filter and refresh the air for optimal tenant and visitor health.

Regulations such as the Clean Air Act have saved thousands of lives from diseases such as emphysema, asthma and heart disease. However, there is still much that can be done to control air pollutants to allow everyone to enjoy cleaner air.

What are some of the main contributors to air pollution?

  • Carbon monoxide is odorless and tasteless but very poisonous in large quantities. Facilities that operate furnaces and/or automobiles need to provide adequate ventilation and install carbon monoxide alarms to ensure safety.
  • Particulate matter is basically “stuff” in the air. This can be man-made or naturally caused, resulting from sources as diverse as burning fossil fuels and power plants to dust storms and wildfires. Particulates have wreaked havoc on the human body since ancient times.
  • Nitrogen oxides are the brown plumes of “haze” that can be seen downwind of major cities. The result of high-temperature combustion, such compounds produce smoggy reddish-brown skies.

Before embarking on new policies and procedures for improving a building’s air quality, it’s important to record a baseline. Testing for radon, carbon monoxide and particulate levels can help guide you about unsafe conditions and provide guidance on the priority order for steps to clean the air.

What kind of policies can a company institute to improve air quality?

  • If your company is relocating or expanding, avoid purchasing office space that is in close proximity to industrial areas which might produce toxins. Of course, if your property is already located in this type of area, you can take steps to safeguard the air in the interior of the building.
  • Don’t allow smoking either in or around your building. Cigarette smoke contains an alarming number of toxins which can remain suspended in the air for long periods of time.
  • Review furniture choices in tenant offices. Pieces made of out cheap particle board may contain formaldehyde, which is a known carcinogen.

Cleaning and maintenance tips for air quality:

  • Proper cleaning of carpets is essential. Carpets act as a filter or trap for dust mites and other allergens. Without frequent vacuuming with appropriate filters, carpets can outgas airborne toxins.
  • Follow suggested maintenance and cleaning guidelines for HVAC systems. Ductwork should be cleaned to remove mold or other contaminants. Filters should be the highest-quality to effectively remove particles down to the smallest micron.
  • Janitorial staff should be allowed to open windows or other ventilation, whenever feasible. Fumes from high-grade cleaning products are a serious irritant.
  • For residences and businesses in high-humidity areas, consider utilizing dehumidifiers to inhibit the growth of mold.

Unlike other disasters that can be seen or heard, air quality is (by its very nature) a typically invisible problem. As such, it can pose detrimental health effects over long periods of time, making it a silent but deadly killer. Taking steps to clean the air will have a direct effect on tenant happiness and productivity.

When a disaster strikes, prior planning and clear decisive action can help save lives.  For the latest emergency management training for facility/building managers, contact Allied Universal, Inc.

Going Green with HVAC

While we are not experts at HVAC, here are some basic tips. For more information, please contact your HVAC professional.

In previous posts in this series, we’ve discussed green roofs and recycling programs. Today we are looking at more “behind the scenes” ways you can reduce your building’s carbon footprint.  According to the U.S. Department of Energy, commercial buildings account for 18 percent of total U.S. energy consumption. In a typical office building, energy use accounts for 30 percent of operating costs, which is the single biggest category of controllable costs. Reducing energy usage can result in significant long-term reduction of building expenses, freeing up capital you could use for other improvements such as landscaping or painting.

Today’s blog covers ways you can improve your building’s HVAC and other systems to improve energy efficiency and save on costs.

Reduce the need for heating and air conditioning:

  • Review building insulation and fill gaps with the most efficient materials.
  • Reduce the building’s “solar gain” by installing reflective roofing materials and tinted windows. These are especially important in buildings located in sunny climates.  Examine office equipment to make sure tenants use the latest technology that produces a minimum of heat. Pay special attention to data centers which require substantial cooling.
  • Simple solutions are best.
    • Encourage tenants to open blinds/curtains where feasible to let in warm sunlight.
    • Ask tenants to close/open windows to warm/cool office spaces before adjusting thermostats.

Selecting and maintaining the heat and AC systems:

  • Review older systems against more efficient, modern units. For many buildings, the initial outlay for a new system could potentially be recouped through annual energy savings. Talk to an HVAC specialist about potential savings.
  • Don’t purchase a system that is too big for your building. Your installer can test to make sure the “load” recommendation is met for your building.
  • Consider dehumidification systems for humid climates and evaporative coolers in dry climates. As the saying goes, “It’s not the heat. It’s the humidity.”
  • Install quality control systems:
    • Programmable thermostats are important for reducing heating/cooling during off hours. Work closely with facility managers to make sure thermostats are set for the correct temperature.
    • Multiple zones are essential for multi-room and multi-floor buildings. Tenants will inevitably have different needs. Some might have 20 employees working in one space, while others might have only a few employees who work in small, individual offices.
    • CO2 sensors dynamically adjust heating/cooling by measuring CO2 amounts.

Proper maintenance:

  • As with all mechanical systems, proper maintenance can extend life and performance.
  • Replace air filters frequently with high quality filters.
  • Inspect all ductwork and piping for any leaks, which can contribute to heat/cooling losses.
  • Check thermostat function to make sure everything is functioning as it should.

Beyond the benefits to the planet and your profits, improving your building’s HVAC systems will lead to comfortable, content tenants. This is great because no one likes to hear disgruntled employees complain about being too hot or cold. And an unhappy employer is a tenant who might not renew his lease in your building! Modern HVAC systems are designed to provide controlled temperatures at maximum comfort.
