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
![Page 38: Pfister Energy Renewable Energy Technologies 2012](https://reader034.vdocuments.mx/reader034/viewer/2022042700/55558863b4c905a5178b47ab/html5/thumbnails/38.jpg)
• 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
![Page 39: Pfister Energy Renewable Energy Technologies 2012](https://reader034.vdocuments.mx/reader034/viewer/2022042700/55558863b4c905a5178b47ab/html5/thumbnails/39.jpg)
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
• 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

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

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
![Page 64: Pfister Energy Renewable Energy Technologies 2012](https://reader034.vdocuments.mx/reader034/viewer/2022042700/55558863b4c905a5178b47ab/html5/thumbnails/64.jpg)
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.

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
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 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.

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.

Instead of running from roofs into sewers, storm water gets collected and stored for later use (toilet flushing, facility cleaning, industrial processing, irrigation, etc.)
