Key Terms

volatile organic compounds, hvac, iaq, dual-band wifi, +2 more

6 terms

volatile organic compounds medical

"the smart thermostat monitors humidity, tracks volatile organic compounds and estimates"

Volatile organic compounds (VOCs) are carbon-based chemicals that easily evaporate into the air at room temperature, like the strong-smelling fumes from paint or gasoline. Investors should care because VOCs can trigger health and environmental regulations, cleanup obligations, fines, and restrictions that raise costs, limit operations or reduce property values; think of them as invisible liabilities that can affect a company’s finances and reputation.

hvac technical

"you won't have a surprise HVAC system failure, and seamlessly saving money"

HVAC stands for heating, ventilation and air conditioning — the systems that control temperature, airflow and indoor air quality in buildings. Investors care because HVAC drives operating costs, energy use, tenant comfort and regulatory compliance; like the engine and insulation of a building, efficient modern systems can lower bills, reduce repair and replacement spending, and preserve property value, while outdated units can create unexpected expenses and vacancy risk.

iaq technical

"indoor air quality (IAQ) information, design themes and color combinations"

IAQ stands for indoor air quality, the measure of how clean and healthy the air is inside buildings and enclosed spaces, including levels of pollutants, humidity, ventilation and odors. Investors care because IAQ influences operating costs, regulatory compliance, tenant and employee satisfaction, and demand for related products or services—think of it like the health of a building’s “breathing” system, which can affect occupancy, productivity and long‑term asset value.

dual-band wifi technical

"supports a wide range of HVAC system configurations and has dual-band WiFi compatibility"

Dual-band Wi‑Fi is a wireless networking setup that broadcasts on two different radio bands—one lower-frequency band for longer range and one higher-frequency band for faster speeds over short distances—like a road with both slow, wide lanes and fast, narrow lanes. Investors watch it because products, offices and retail sites with better, more reliable Wi‑Fi reduce downtime, improve customer and employee experience, and can be a competitive or cost factor for companies that sell connected devices or depend on heavy, real-time data use.

energy star technical

"Honeywell Home ENERGY STAR ® certified thermostat users, in 2023, who adopted"

A government-backed label that indicates a product, appliance or building meets set energy-efficiency standards. For investors, an ENERGY STAR rating signals lower ongoing utility and maintenance costs, stronger appeal to cost- and eco-conscious buyers or tenants, and possible access to incentives or reduced regulatory risk—think of it like a fuel-efficiency sticker that helps compare long-term operating costs and market desirability.

msrp financial

"U.S. and Canadian retailers for $219.99 (U.S. MSRP). Nearly half of consumers"

MSRP is the price a manufacturer recommends retailers charge for a product, like a suggested sticker price on a car or appliance. For investors it signals pricing strategy and potential profit margins: if retailers sell above it demand may be strong or supply tight, while deep discounts below it can indicate weak sales or margin pressure. Comparing MSPR to actual selling prices helps assess revenue realism and competitive dynamics.
