How 75F Improves Heat Pump, Fan Coil Unit, & PTAC Energy Efficiency

By Sarah Baker on Jun 11, 2019 6:00:00 AM

Imagine a residential smart thermostat with machine learning, remote control, and a mobile app. Apply that to commercial buildings and you get the wireless-networked 75F Smart Stat: the world’s smartest commercial thermostat. Then combine the 75F Smart Stat with a full Building Automation System (BAS) and you get an incredible combination of group controls for several HVAC systems, along with lighting and boiler and chiller plant controls for a unified, wholistic commercial BAS at half the cost of the competition.

Let's take a look at how it works.

4 Energy Conservation Measures for Energy Consultants

By Sarah Baker on May 21, 2019 10:29:27 AM

Frustrated about how few of your Energy Conservation Measures (ECMs) get implemented? Change the payback equation with a simple, low cost Building Automation System (BAS) from 75F that can support nearly all ECMs, prescriptive and custom. With modern technology, such as cloud computing, machine learning, wireless networking and mobile apps, 75F can rapidly implement ECMs with little or no programming and at half the cost when compared to a traditional BAS, with energy savings from 30% to 50%, a lower installation cost and a one to three-year payback.

How the 75F System Works with VAV Systems

By Sarah Baker on Apr 18, 2019 6:13:00 AM

There's a lot of waste involved with VAV systems commonly used in office and commercial buildings. Typically, VAV systems operate with roof-top units (RTUs) in cool-only mode. The supply air temperature is held constant at 55°F and, when a zone falls below its setpoint, the damper closes and reheat is enabled. When a zone is above its setpoint, the damper opens fully to allow as much 55°F air as possible into the zone to cool the space quickly. This cycle often involves first cooling and then heating the same air. Since the RTU operates in cool-only mode, the 55°F air must again be reheated before it is discharged back into the space to keep the zone's air temperature in balance.

See the waste?

How Can Class B Buildings Get Smarter?

By Sarah Baker on Oct 17, 2018 7:52:14 AM

Could your office building be described as… average? Maybe it doesn’t have a fountain in the lobby, or a view of the ocean – but you have four solid walls, a non-leaking roof, and only a few drafty cubicles. Have you ever tried to make your building work with an HVAC hack? Maybe you even taped a piece of cardboard over the vent to manage the airflow. That would be pretty clever of you, MacGyver.

So, if your office building is around 10-20 years old, has some wear and tear, but is generally in good shape, you probably have a Class B building. This is good news. Investors tend to target these buildings since, with a few upgrades, they can easily become Class B+ and compete readily with Class A properties. One of those upgrades is making your Class B smart – and it’s probably easier than you think.

Occupant Experience: Optimize Air Quality, Comfort & Zone Control

By Ben Wallace on Jul 30, 2018 11:00:27 PM

Your building could be working harder for your occupants. The Occupant Experience (OE) is a key measure of building performance, creating multiple benefits for building tenants and owners alike, especially when combined with Operational Efficiencies (OE) to yield what we call OE2 . Your commercial building can improve productivity, health & comfort with smart zone control of temperature, air quality and lighting to suit occupant preferences and workflows.


Is your building working for your occupants?

At 75F, we're on a mission to make buildings work for the people, especially the people buildings are designed to accommodate - their tenants. And, all building stakeholders, from building owners to facility managers to architects, can agree on the importance of creating the optimal occupant experience. However, comfort is recurring top issue and tenant complaint for commercial real estate properties. And, with 85% of commercial buildings lacking intelligent building systems, yet commercial real estate (CRE) properties are projected to have the highest growth in IoT connected devices deployments, the time is right to get smart with your building. It's more affordable and easier than ever to install a sophisticated IoT-based building automation systems to reduce energy and other operational expenses, while proactively optimizing workplace environments for employees and other occupants.

VIDEO: VAV Box Controllers Deserve a Smarter Approach

By Ben Wallace on Jun 28, 2018 9:16:24 AM

The Variable Air Volume (VAV) with reheat HVAC systems and box controllers commonly found in commercial office buildings present a great opportunity for building owners and managers to save energy, improve operational efficiencies and better manage occupant comfort, with more sophisticated sensing and controls orchestration. These VAV with reheat systems tend to use the rooftop unit (RTU) to first cool supply air to a standard 55 degrees, then typically use the electric heat at the individual VAV box reheat elements throughout the building for heating supply air to desired temperatures for the zones. Though, the traditional VAV system has several issues with inefficiency and lack of sensing and controls management.

Check out this video to learn how you can improve building performance with operational efficiencies and a better occupant experience with the 75F Smart VAV with Reheat solution.
