Liberty Science Center

Liberty Science Center

In April 2008 The Liberty Science Center, a 295,000 square foot educational science center for the general public, installed Noveda Technologies SunFlow Monitor™ and EnergyFlow Monitor™ to optimize the facility's newly installed solar photo voltaic system.

SunFlow Monitor™ records and displays in real-time all electrical energy coming into the building from the grid, electrical energy going out from the building to the grid, electrical energy consumed by the building, and electrical energy produced by the solar photo-voltaic system.

After the first night in use, SunFlow Monitor™ data showed that the facility was consuming three times more energy during the night than originally estimated. Between the hours of 10:00 pm and 6:00 am The Liberty Science Center was consuming unnecessary electricity to run the air conditioning, lighting and other energy intensive systems of the building.

Because of the instant feedback, facility operations staff at Liberty Science Center discovered that the air handling units were running in occupied mode during the night, bringing hot, humid air into the building. By readjusting the night settings, daily electrical consumption was reduced by approximately 11.5%. It was estimated that this problem was occurring for the past year, costing an average of $5,800 per month or nearly $70,000 per year! In terms of the environmental impact, the energy savings resulted in daily reductions of 1.24 metric tons of CO2 greenhouse gases. Noveda's technology offered a three month payback on their investment.

Overall, installation of the SunFlow Monitor™ resulted in an immediate daily electrical savings of 11.6% and a significant reduction in greenhouse gas emissions.

The first eco-friendly billboard will be constructed in Times Square

A Times Square billboard goes green
The first eco-friendly billboard will be constructed in Times Square, entirely powered by wind and solar power.
-- Consulting-Specifying Engineer, 11/19/2008
According to the New York Times, the first eco-friendly billboard will be constructed in Times Square, entirely powered by wind and solar power. The $3 million Ricoh Americas billboard will be fitted with 16 wind turbines and 64 solar panels. The 126 x 47 ft billboard on the Great White Way, weighs 35,000 lbs, rests 55 ft off the ground, and wraps around the northwest corner of Seventh Avenue and 42nd St. The billboard will generate its own electricity, which is enough to power six homes for a year, and the self-generated power will save as much as $12,000 to $15,000 per month in utility costs and prevent 18 tons of carbon from being released into the air. Lighted by 16, 300-watt floodlights, the billboard will feature a custom-printed opaque vinyl sheeting that bears the Ricoh logo.

The cylindrical Ricoh drum turbines have no sharp blades and will provide 90% of the sign’s power. The rest of the sign’s power will come from the solar panels, which feed electricity to eight collection batteries up in the sign. Unlike the tall propellers in a typical wind farm, the cylindrical Ricoh drum turbines have no sharp blades. Tourists, residents, and people passing by will be able to see the 26 blades spinning in the sign’s 16 turbines, piled in four 45-ft. tall vertical stacks. Operating at an average speed of 10 miles an hour, the turbines will generate 22 kW.

The only projected problem with the solar and wind powered billboard is what happens to the sign when there is no sun and no wind. Ricoh claims that the drums are so perfectly balanced, that their rotors could be turned by the wind from a single household electric fan. “The turbines would most likely generate enough power to keep the sign lighted even after four days without wind or sun. But the company is prepared for the sign to go dark” said Ron Potesky, a senior marketing vice president for Ricoh Americas Corp. Unlike stalklike propeller turbines, which require unidirectional, or “clean”, wind to function, Ricoh’s revolving drums use turbulent, multidirectional winds. The turbines provide usable power from winds as weak as 5 mph and rotate safely in winds up to 100 mph.

Laser Sensors for Wind Turbines

A system that detects gusts before they arrive reduces wear, boosts output.

I knew there was a use for LASERS!!!!!

Solar Energy to Enterprise


Whether you want to monitor a single solar energy system, a building, or an entire enterprise, Noveda Technologies provides instant access to critical systems information through three award winning products: SunFlow Monitor, EnergyFlow Monitor and Facilimetrix

For live demos of each, click on the product page links!

Each web-based product provides comprehensive and detailed information about your building's energy performance through easily readable graphics displays.

Your efforts in sustainability and commitment to renewable energy are important to your community, your employees, and your clients. Inform, educate, and motivate everyone who interacts with your business through kiosk displays and web access to real-time data about your conservation efforts. Dynamic visualizations will not only inform those around you about your efforts but engage them in participating in achieving your goals for environmental stewardship.

Noveda Technologies Energy Monitor Systems allow you to:

Monitor and track whole building energy consumption

Benchmark your building’s current energy consumption against a comparitive Energy Star building model, building

    energy model, previous utility bills, or energy reduction target

Store historical data and reports of electrical consumption, demand, weather and other critical elements

Establish your building’s carbon footprint

Track the impact of energy savings initiatives

Achieve LEED-EB and LEED-NC performance measurement, enhanced metering and measurement, and verification credits

Inspire employees to conserve energy

Building Owners and Managers can now:

Provide real-time information about temperature set points, overrides versus actual readings

Assign a facility performance index to your building based on information from your building’s energy management

    system and building’s energy usage

Identify which building(s) in your portfolio are using energy efficiently and providing a comfortable work environment

    and ones that may need attention

Verify results of energy efficiency projects, renewable energy projects, service contracts, or compliance with energy

    or carbon footprint reduction goals

Expose hidden building performance information in the building management system

First Net Zero Electric Building

How many others are there in the US? Commercial, industrial or residential?


Air Conditioners

Very cool news about trees and why we need them.

New Advanced Solar Cell

Dye Process

Using a new dye process they have developed a very efficient new type of solar cell. Hopefully this will get us nearer to the efficiency of oil in energy.
