Workplace sensors help to get the job done

Healthy workplaces with optimal temperature and air quality can boost productivity. A 2014 study published by the National Center for Biotechnical Information measured a 38.56% impact on job performance as a result of temperature extremes.

In commercial and office buildings, sensors help ensure comfort and safety within the environment.

Here is how they boost workplace wellness:

Providing safety

Smoke detectors are required in most commercial buildings because they save lives! Among the common building code requirements, the sensors must be powered through building wiring with a battery backup. They are tagged with the dates of the most recent maintenance and when backup batteries were replaced.

Carbon Monoxide presents a risk wherever fossil fuels are burned. That includes boilers, as wells as stoves and fryers in many commercial kitchens. Also, CO detectors must be installed if vehicles run in an attached garage or warehouse. Several states require them in all commercial lodgings.

Maintaining or monitoring temperature


The thermostats that control Heating, Ventilation, and Air Conditioning (HVAC) systems are the most familiar but the sensors can have other purposes as well. In certain industrial spaces, warehouses, tool sheds, and other areas lacking HVAC equipment, the sensors may warn of extremes when portable heat or cooling fans can save inventory or plant production.


Replacing stale air

Even at an ideal temperature, stale air hinders concentration by triggering headaches and sleepiness. Extreme CO2 concentrations above 40,000 parts per million (ppm) can cause brain damage, and even be fatal. Occupied Indoor spaces will typically have 350 – 1,000ppm.

If office air seems stale or worker health seems affected, an initial assessment may determine if CO2 sensors should be installed. CO2 monitors and meters may be wired, wireless, or handheld. Some, integral to HVAC components, may control the fresh outdoor air being supplied to the system.

Controlling humidity

At different temperatures, excess humidity in an office environment brings chills or perspiration, guaranteeing complaints in any season. Relative humidity sensors are most common in industrial and commercial applications. They remain reliable even at high temperatures and when condensation or chemical vapors have occurred. Available solutions include hand-held hygrometers for occasional assessment to wall-mounted or duct-mounted transmitters.

HVAC systems are designed for heating and cooling, not for efficiently controlling humidity. Relative humidity sensors should control dehumidification systems, not HVAC, which can cool the air too much while removing humidity from it.

If not required for fire and smoke detection, sensors can be installed without wiring. Batteries can supply the power for months, and readings can be transmitted via wi-fi.

The minor expense and simple installation can pay dividends. In its Office Building Occupants Guide to Indoor Air Quality (IAQ), the EPA reports that improved IAQ brings improved productivity along with fewer lost work days. The agency advises that poor indoor air could cost tens of billions of dollars each year in lost productivity and medical care.

AWARE of CDC and NIH guidelines

The Baseline Property Condition Assessments described in ASTM E2018-15 do not specify consideration of infectious disease transmission concerns. In a pandemic and post-pandemic environment, that inspection and documentation is essential.

Buildings open to the public must comply with local regulations. For best results and greatest public acceptance, any planning for building repairs and maintenance should not overlook current CDC and NIH guidelines.

Optionally, ecoPreserve's can assist with a comprehensive GBAC STAR™ Accreditation which extends beyond the building to include the goals, actions, equipment, and supplies needed to implement best practices for outbreak prevention, response, and recovery.

An OPTIMIZED Assessment

Certified Sustainability Consultants on a facility assessment team can discover ways to lower energy costs. Their understanding of HVAC equipment suitability and condition along with the specifics of LED lighting retrofits can provide offsets for needed investments in upgrades and replacements.

Knowledge of water systems can bring further savings while averting water waste. It can all be part of an assessment which might otherwise overlook water fixtures and irrigation schedules.

How should a facility be ASSESSED?

A thorough facility assessment finds the issues - on the surface or below - which have a potential negative impact on the building. That brings the facility to meet building codes. Beyond that, the assessment proactively addresses the deficiencies not covered by code.

The occupants of a building benefit as the assessment reveals conditions having a potential impact on their health or safety. The assessment must not overlook those conditions, nor fail to consider the frequency and duration of occupant visits.
