IEQ monitoring for new build projects

A new building is your only chance to wire monitors in the easy way. Hardwire indoor environmental quality monitors into the fabric of the building itself: powered over Ethernet, speaking BACnet to the BMS, and upgradeable for decades without ever touching the wall again.

Which IEQ sensors are best for a new building?

For new construction, wired monitors are the better choice: one low-voltage cable (Power over Ethernet or 12–30V DC) carries both power and data, so there's nothing to plug in and no batteries to replace. Connectivity stays Ethernet-stable, and the device speaks BACnet/IP natively to the building management system. Choose a modular monitor so new sensors can be added later without any new wiring.

Four questions to ask before deploying monitors into a new building

One of the biggest mistakes projects make is treating IEQ monitors as an afterthought, which leads to expensive fixes later. Ask these questions from day one.

Power

How will each sensor get power?

You shouldn't have to put a monitor where an outlet happens to be, or hang an adapter off a brand-new wall. Plan one low-voltage cable now so you can place each monitor exactly where the space calls for it.

Connectivity

How will the data get out?

For a wired solution, your best option is setting up Ethernet from the start. Skip it now and you'll have to run cables later, or rely on the office Wi-Fi, where every password change means updating every sensor on the network.

BMS Integration

Can it feed data to my BMS?

Pick monitors that speak BACnet to the BMS and stream to the cloud at the same time. Otherwise, you’ll install a second set later: one for the integrator, one for the workplace team.

Maintenance

What will need maintaining in year three?

Batteries die. Wi-Fi passwords change. Hardwired power and connectivity eliminate those headaches: install once and leave it alone. The only maintenance is sensor calibration (required for any monitor), which is easy with a modular sensor design.

Air Quality Pillar-why measure with Kaiterra-Accurate and calibrated-4

PoE or low-voltage. One clean install.

One Cat5e/6 cable can carry both power and data over standard PoE, or connect directly to a 12–30 V DC low-voltage circuit like any BMS field device. Flush-mount it on a standard electrical box so there’s nothing hanging off the wall.

Ethernet-first for stable connectivity.

Run data over standard Ethernet at up to 100 Mbps. No Wi-Fi onboarding, no gateway, no dead zones behind a plant-room wall. Wi-Fi is there as a backup when wiring isn’t practical. Readings are pushed every minute, stable and frequent enough to run your control logic.

Cloud analytics. Native BMS. One monitor.

Kaiterra monitors support BACnet/IP and Modbus over RS-485, with BTL certification for native BMS integration. The workplace team gets cloud-based analytics and insights, while the BMS integrator gets a native device: no gateway, no middleware, no translation layer.

Install now. Measure more later.

Kaiterra monitors feature a modular design that lets you add sensors later without touching the wiring. Get new monitoring capabilities like inorganic gases or sound by adding new modules, instead of buying and installing an entirely new monitor.

Building already occupied?

Skip the cabling: our wireless monitors peel and stick to the wall and run for years on batteries.

FAQ for new construction projects

Should I use wired or wireless IEQ monitors in a new building?

Wired, wherever you can. In new construction the cabling cost is marginal, and you get permanent power, Ethernet-stable connectivity, native BMS integration, and no batteries to replace for the life of the building. Use wireless for later tenant fit-outs or spaces you can’t cable.

Can air quality monitors be powered over Ethernet (PoE)?

Yes. The Sensedge Mini (PoE) is powered and connected over a single Cat5e/6 cable from a standard IEEE 802.3af or 802.3at switch (Class 3, under 10 W). Midspan and endspan power sourcing are both supported. Alternatively, wire it to a 12–30 V DC low-voltage circuit.

Do Kaiterra monitors integrate directly with a BMS?

Yes, natively. The Sensedge Mini is BTL-certified under the BACnet Smart Sensor (B-SS) device profile, speaks BACnet/IP over Ethernet and Modbus/RTU over RS-485, and can publish to cloud or on-premise MQTT.

How many IEQ sensors does a new building need?

A common design rule and the WELL v2 requirement is at least one monitor per 325 m² (3,500 ft²) of regularly occupied space, placed at breathing height in representative zones, plus in-duct monitors on air-handling units where you want supply-air data. Our team can help you specify placement during design.

Do wired monitors support WELL, LEED, RESET, or Fitwel?

Yes. The Sensedge Mini is RESET Grade B certified and Works with WELL. The Kaiterra Data Platform provides the continuous monitoring reports required by those certifications.
