SENSORS & CONTROLS CAMPAIGN WINNER

Congratulations Jim White!

Jim is Senior Energy Conservation Engineer at Chelan County Public Utility District in Washington State. James designs and implements energy efficiency and renewable energy programs for public utilities. He was the originator and designer of Chelan County PUD’d award winning Sustainable Natural Alternative Power (SNAP) program for making solar and small wind cost effective in an area with some of the cheapest electric power rates in the nation.

Jim’s idea is an improved design for variable air volume (VAV) mixing boxes. Combining temperature and CO2 sensors to control minimum airflow settings of individual VAV boxes, as Jim proposes, would yield significant energy savings.

The Opportunity:

Jim White presented his idea in front of 300 technical experts, lab scientists, corporate partners, small businesses, and financial institutions at the Office of Energy Efficiency and Renewable Energy’s Industry Day, hosted at Oak Ridge National Laboratory. You can view a video of his exhibition at here. He will also have the opportunity to explore partnerships with the lab and/or industry partners to advance market adoption of his ideas.

Enhanced Parametric Design & Control Tools on the NET

Today’s typical design, construction and operation methods have several disconnects that prevent the original design intent from fully being embedded into the building’s control intelligence. Worse yet, no building performs exactly as originally modeled in the design process, and most current control approaches are static and do not adapt or optimize to real operating conditions. Building control systems tend to degrade ...more »

Passive heating and cooling support for existing buildings

Sophisticated building control systems are available for high-tech buildings and greenhouses which help regulate the internal environments of those places. For home owners and small building owners who seek to maximize the passive heating and cooling potential of their EXISTING buildings, a simpler system should be possible. By taking indoor and outdoor temperature and humidity readings, using local weather service information ...more »

Bluetooth energy control

This control device can be applied to both residential and commercial applications. The control receiver will activate a single or series of control relays that will enable power to flow to computer related hardware and or house loads ie: HVAC lighting that would only require power once a known (previously paired) bluetooth device is within proximity. Once the handheld device is no longer in-range, the control load ...more »

All homes = smart homes!

Every home wastes at least 30% of its energy in delivering services that the occupant never uses! Much of this is to do with occupant habits and the lack of knowledge and incentive to change behaviour. Examples of such wasteful services might be: 01. Heating the building during unoccupied hours 02. Setting the thermostat to higher temperatures only to use the window to lose excess heat 03. Leaving the lights on when ...more »

Combined CO2 & Temperature Sensor Control of VAV Dampers

The idea is to replace individual zone temperature sensors with commercially available sensors that also measures CO2 to control the damper inside a variable air volume (VAV) mixing box. Incorporating a CO2 sensor with the temperature sensor will allow the mixing damper in a VAV box to close completely if the space does not have a call for ventilation air or air conditioning. Existing variable air volume systems waste ...more »

Perfect dimming for general lighting

• Dimming can save significant amounts of energy anywhere lighting is used

• Current dimming solutions are ugly. With only two modes, high/low, the state change is obvious to the point of distraction.

• How do we get more dimmers installed?

• How do we make dimmers that are not so jarring?

Lower Electrical Consumption for Lg Induction Loads - Day 1 & 2

There's a company on Staten Island, NY, that has taken the old, fixed-capacitance design, power factor controller and made it far more effective by adding a computer that samples each leg of a 3-phase circuit 720X, per cycle, per second. With a patented switching algorithm, designed to switch load to a different capacitor to avoid heat and component fatigue, UL assigned a new class to this "carry-on-luggage" sized device, ...more »

Optimize building O&M and upgrades with diagnostic benchmarking

Most building owner/operators have no idea if their facility is operating anywhere near its efficiency potential, let alone what O&M changes or upgrades are likely to cost-effectively improve efficiency. A field test achieved 19% measured O&M savings at no cost in 25 professionally managed buildings, and identified an additional 15-20% quick payback capital upgrade savings potential.

Smart Locus Intelligent Building Management System

While current controller technologies can deliver certain savings in managing HVAC systems, the rigid programming of a controllers’ sequence of operations (control without real time analysis) is not able to adapt to fluctuating interior and exterior conditions. Typically, BMS commands will become less and less optimal as time passes and environment and building changes. This leads to energy wastage and spiraling energy ...more »
