SOLAR THERMAL

Modular Solar Thermal

Harness the radiant energy from the sun and convert it to heat for the generation of hot water. • Roof-mounted collectors trap the sun’s rays and convert it to heat • The absorbed solar heat warms a specialized, non-toxic fluid inside

One of the most effective alternative methods of generating energy and lowering utility bills!

• A digital controller then activates the solar station to pump this fluid through the storage system via a closed-loop serpentine copper pipe

• The piping is coiled around the potable water that is heated

• Fully integrated packages available • Fast and easy installation -- no soldering • Freezing and overheating issues are

resolved • Low maintenance "plug & play" design • High selectivity absorber coating and

optimum thermal insulation maximize efficiency and minimize energy loss

• Digitally controlled with energy generation calculator

Suitable for pitched roof, flat roof, awning, & facade installation! Solar Thermal

Premium solar thermal applications utilize pressurized, closed-loop (propylene glycol) systems

Building Integrated Solar Thermal Eliminates the visibility of the solar thermal collectors

• Solar energy is absorbed into a concealed collection system that is hidden just below the roof or wall.

• Hidden from sight, it’s also protected from harsh weather for a longer life expectancy / warranty.

• Installed during new construction, renovation or a re-roofing process.

Seamless integration into building architecture frees up roof area to accommodate additional clean energy technologies -- photovoltaics!

DAYLIGHTING

Daylighting

Daylighting is an engineered,

sophisticated skylight that brings natural, bright light into a building space while significantly reducing power consumption by both HVAC and lighting systems.

turn sunlight

into work light

What is it?

Daylighting

• An energy-saving array of through-the-roof luminaries

• Collects sunlight through prismatic rooftop lenses

• Directs and distributes light downward into interior space as cool comfortable light Light generated covers more than five to ten times the area of a conventional skylight

Various daylight savings control options available to maximize sunlight utilization and improve cost savings throughout the day

Daylighting

Highlights of Pfister’s SunShine Daylighting System include • Savings of 40% to 80% on lighting costs • Brings aesthetically-superior daylight indoors • Reduced eye fatigue & UV filtered protection provide safer worker conditions &

improve performance • Uses renewable / sustainable energy – Sunlight! • Reduces greenhouse gasses, pollution, and dependence on foreign petroleum • Summertime kW demand is 75 to 100 percent lower • Little, if any, heat is transmitted -- in or out • 20-year useful life cycle and very low maintenance

120 installed Daylight units can save as much as 500 barrels of oil and 143 tons of greenhouse gasses each year!

SOLAR LIGHTING

Solar Lighting

Battery

During daylight hours sunshine on the solar panel creates electricity

System Manager

The system manager controls current flow to charge the battery

As the sun goes down, the panel stops generating electricity

After dark, the system manager draws electricity stored in the battery to power the light

Solar Lighting – How It Works

Solar Lighting Solar Lighting Applications: • Parking Lots • Pathways • Security • Bus Stops / Shelters • ATM Machines

Trenching and installing wires in urban areas can cost from $8 to $10 per linear foot and re-paving is extra!

BUILDING-INTEGRATED WIND ENERGY SYSTEMS

Single Vertical Axis Turbine

Grouped Horizontal Axis Turbines

Building-Integrated Wind Systems

Building-Integrated Wind Systems

Building-Integrated Wind Systems

Capitalize on the unique wind patterns created by the building's height, location, position, and architecture!

Why Building-Integrated Wind? • Lightweight, small

turbines • Easily integrated into

building’s architecture • Work well in fractured

urban wind environments • Effective in low-wind

regimes • Minimizes issues with

zoning

Traditional horizontal axis wind turbines have to rotate to track wind

Vertical axis wind turbines collect wind from all directions without tracking

Vertical vs. Horizontal Turbines Advantages of Vertical Axis Turbines (VATs) for Building-Integrated Applications

VATs offer several advantages for building integrated wind; however, HAT’s also have their place for certain applications

• In urban, built-up environments, changing wind direction and turbulence are inevitable

• Do not require consistent wind direction to continue producing power

• Easy to integrate with existing masts and buildings

Aerodynamics of Urban Wind As air passes over the building there is a region of accelerated airflow. Placing a turbine in this region boosts the amount of electricity produced.

Effect of Adding a Venturi Wing Above the Turbine

Building-Integrated Wind Systems

Project Development Steps for Wind You’re interested….so now what?

Assess the available wind resource at your location:

• “Best” wind resources typically found along the coast, near waterways or on ridgelines

• Assess suitability of site relative to terrain, adjacent

buildings, and other potential obstructions

• Use internet-based resources: Wind Explorer, wind maps,

and wind rose to assess site

FUEL CELLS

Fuel Cells

What are they? Electrochemical power generators with exceptionally high electrical efficiencies that produce both electricity and heat without combustion and the pollutants associated with burning conventional fuels.

Fuel Cell Power Plants enable the clean production of on-site, grid-independent energy for base load applications!

Fuel Cells Hydrogen Fuel Cells produce

Combined Heat & Power (CHP) through an electrochemical,

non-combustion process

• Cogeneration thermal recovery enables production of combined heat and power (CHP)

• High electrical efficiency means savings through reduced energy consumption

• Increased reliability of operations • Reduced on-site emissions • Premium power quality • Quiet 24/7 operation cycle • Modular and scalable system sizes • State / federal financial incentives

By displacing energy demand previously met by high utility

rates, savings create attractive payback in as little as

2 to 3 years!

Fuel Cell Advantages

Fuel Cells vs. Conventional Fossil Fuels Plant

Efficiency of the average fossil fuel plant is only 33%. • DFCs are 47% efficient • When utilizing waste heat (e.g. for domestic hot

water or steam), DFCs are 62% to 70% efficient • Plus there are no transmission losses! • Compared with a typical fossil fuel plant, DFCs

of equivalent power output deliver sizeable pollution reductions: 99.94% decrease in NOx 99.99% decrease in SOx 55.00% decrease in CO2

Given their cheaper

fuel costs and high

efficiency, fuel cells

deliver a lifecycle

cost per kWh that is

substantially better

than micro turbines.

Fuel Cells The DFC300 provides a base load of 300 kW of energy at >95% reliability plus 500,000 BTU / hr of thermal energy. Megawatt sizes also available.

DFC1500 (1.2MW)

DFC3000 (2.4 MW)

GEOTHERMAL

Geothermal

Geothermal Systems average 40 percent greater efficiency than

air-source heat pumps, 48 percent better than natural gas furnaces and 75 percent better

than oil furnaces!

The temperature of the upper 10 ft of the Earth's surface is nearly constant between 50-60º F. As a result soil temperatures are usually warmer than the air in winter and cooler than the air in summer. Geothermal heat pumps use the Earth's constant temperatures to heat and cool buildings by transferring heat from the ground (or water) into buildings in winter and the reverse in the summer. Although, most buildings still use traditional furnaces and air conditioners, geothermal heat pumps are the most energy-efficient, environmentally clean, and cost-effective systems for temperature control.

GREEN ROOFING
