36. SOLAR THERMAL

37. 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
• 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
One of the most effective alternative methods of generating
energy and lowering utility bills!

38. Solar Thermal

39. 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!

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

64. Vertical vs. Horizontal Turbines
Advantages of Vertical Axis Turbines (VATs) for
Building-Integrated Applications
• In urban, built-up environments, Traditional horizontal axis wind
turbines have to rotate to track
changing wind direction and wind
turbulence are inevitable
• Do not require consistent wind
direction to continue producing
power
• Easy to integrate with existing
Vertical axis wind turbines collect
masts and buildings wind from all directions without
tracking
VATs offer several advantages for building integrated wind;
however, HAT’s also have their place for certain applications

65. 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.

76. GEOTHERMAL

77. Geothermal
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.
Geothermal Systems average 40
