Essex County Greenbelt

A 1,500-watt high-efficiency photovotaic solar module follows the sun during the course of the day, providing approximately 10% of Greenbelt’s electric needs.

A high-efficiency, HVAC air filtration system brings in fresh air and conditions it. The cooling system contains no chlorofluorocarbons (CFCs).

Four heat zones allow for inscreased control over heating for comfort and energy efficiency.

State of the art insulation, called icynene, emits no unhealthy vapors and reduces noise, and has the highest R-factor rating of any insulation available.

A high efficiency gas heating system gets up to 97% efficiency. Electricity is supplied through Mass Energy Consumer Alliance, which utilizes alternative hydro, biomass, wind and solar energy sources. Our heat management system helps regulate indoor air temperature with the lowest possible energy use.

Compact fluorescent light bulbs light the building with only about 25% of the energy used by incandescent bulbs; also, LED bulbs save energy in all exit lights.

Optimal energy performance windows are double-thermal paned, providing optimal energy conservation.

New England Biolabs

NEB's lighting control system automatically shuts off office and laboratory lighting when the areas are unoccupied.

NEB's heat reclaim system recycles heat that is exhausted from the building to help heat incoming fresh air.

NEB's chillers use free cooling when outside temperature is below 50°C, which allows chillers to shut off and still keep the building cool.

High efficiency motors and lights are used at NEB. The motor drives reduce the speed of motors when not in use.

Gloucester Residence

A 4.3 kilowatt (kW) photovoltaic (PV) system was installed on the roof. The system will provide over 100% of annual electricity needs for the house. Excess electricity will be sold back to the electric company.

A 3-panel solar hot water system will provide approximately 60% of annual hot water needs for the house.

The attic has R-76 insulation (cellulose) with a radiant barrier (reflective bubble wrap) to reduce summer attic temperatures.

Walls have an added R-30 (5” of closed cell foam) to the existing R-13 wall system for a total of R-43.

Windows have triple-pane, argon-filled, low-emissivity glazing.

All appliances are ENERGY STAR rated.

The lighting system uses all compact fluorescent lights (CFLs) and light-emitting diode (LED) fixtures and bulbs.

Air leakage: Air leakage reduced to 300 cubic feet per minute (CFM) at 50 pascals of pressure, as measured by a diagnostic blower door.

EBSCO Publishers

Solar Energy: Installation of a 192-panel, 36 kW photovoltaic solar panel system on the roof of our largest building, which is expected to offset 20% to 25% of the building’s energy needs. We are currently installing a second 192-panel photovoltaic solar panel system on an additional building.

Installed a solar-based hot water system for the company café.

Converting fleet of company-owned cars (US & Canada) to hybrid vehicles.

Exploring possibility of installing a wind turbine on the roof of the company parking garage, designed to convert wind into energy used for electricity.

Light bulbs have been changed from incandescent to high efficiency fluorescents, and most areas have been equipped with either timers or motion/sound sensors that shut off the lights when not occupied.

The Green Grid: As a large database provider with two data centers on the Ipswich campus, EBSCO Publishing joined The Green Grid, a global consortium designed to advance energy efficiency in data centers and business computing systems.

Installed “Vending Misers” on vending machines and coolers around campus to control the flow of electricity and help to reduce energy consumption by up to 50%.

Cider Hill Farm

To date, we have installed three 10-kilowatt Bergey wind turbines, which produce about 9,000 kWh each. Two of the wind turbines are 120 feet tall and the third stands at 100 feet.

We have installed one 10-kilowatt Evergreen solar panel array that produces approximately 12,500 kWh per year.

The farm recently installed three outdoor hydronic wood boilers that burn wood and use hot water to transport the energy needed to heat 11 greenhouses and three residences.We are using only seasoned hardwood so they are burning cleanly.

Latitude 43

The sun shades over the deck also heat the dishwasher’s hot water.

Extra insulation in the walls and roof system lower heating and cooling requirements. Our windows are extra insulated to minimize heat loss and tinted to minimize solar heat gain.

Our flourescent lights are dimmable and have a warm tone. Outside we use metal halide vapor lights. Operable skylights provide energy free light in the daytime and energy free cooling in the summer. Motion sensors on bathroom lights turn off the lights when people leave. Solar LED navigation lights on the deck and piers charge up during the day and shine all night.

The concrete floor contains a radiant heating system.

Xlerator hand dryer uses 80% less energy than paper towel. doesn’t create waste, works in 15 seconds with 181 miles/hour air at 135°F (especially nice in the winter).

Downriver Ice Cream

All light bulbs are Compact Fluorescent.

The building is set up for solar power.

The hot water heater heats water on demand only, to conserve electricity.



Energy and Atmosphere Resources

Energy Service Companies
provide service packages that typically include financing, installation, and maintenance of energy-saving capital improvements. Services are provided through performance contracts, which guarantee that payments will not exceed energy savings.

Suppliers of energy-efficient equipment and services
offer a wide range of options to exchange energy-intensive equipment with more efficient analogs. Many have products certified through a third-party program, such as the U.S. Environmental Protection Agency’s Energy Star label.

Utility companies
may work with industrial and commercial consumers to implement on-site energy-efficiency measures, which may decrease usage or shift a portion of it to off-peak hours and rates. The restructuring of the utility industry in many states allows energy users to choose service providers; many utilities entering the deregulated market offer energy from alternative, renewable sources such as wind, geothermal, and solar.

Green Power marketers
are stepping up to compete against traditional power conglomerates and offer customers renewable-energy packages. Developers of solar, geothermal, and wind-energy technologies continue to refine and market their products.
The Green Power Network

Federal, state, and local governments
can mandate the deregulation of the utilities industry and offer economic incentives to facilitate the development of renewable energy. Government can also establish regulations such as requiring that a certain percentage of power be derived from renewable energy, as they have for their own facilities.

Buildings consume close to 40% of the energy and 70% of the electricity produced in the United States annually, according to the U.S. Department of Energy. Energy-management practices and energy-efficient appliances and equipment can reduce energy costs by at least 20%—a net savings opportunity worth more than $11 billion by 2010 for the U.S.

By increasing efficiency and using renewable energy technology, we can do good while saving money.
