Small Urban Renewable Energy...

CypressUnited States

I passed a site of small wind and solar installations on the campus of a branch of our community college. The wind turbines are vertical axis (VAWT).

Earthship Highly Sustainable Housing

New MexicoUnited States

We noticed these earthships while driving through the state of New Mexico. Earthships are incredibly well designed, innovative, low-impact homes. They generally offer a multitude of sustainable features, are built with sustainable materials, designed for efficient heating and cooling, harvest both energy and water, and utilize a great variety of other friendly practices.

Geothermal System Piping Design

MeridenUSA

Earth Energy USA has a patented pipe that makes geothermal heating, cooling, and hot water affordable. Our pipe is a flexible 4.5″-wide round bundle, utilizing a 2″-wide round plastic HDPE center pipe as the core pipe of the system. This pipe has small 1/2″ holes evenly drilled throughout its length, which allow for a cement grout to seep through and fill any voids in a system borehole wall. This creates a solid, filled borehole. Around the center pipe are eight smaller plastic pipes wrapped in a spiral fashion to allow for maximum surface heat transfer to your water. Four of the pipes carry the closed water loop down the borehole to a U-turn fitting at the bottom, while the remaining four pipes bring the water loop back up, completing the system.
With this design, whereas other geothermal companies use three to four boreholes, Earth Energy USA only requires two. This makes for significant savings and also allows us to install geothermal systems in more urban areas. The boreholes we drill bring up the natural temperature of the earth, which is a constant 55 degrees Fahrenheit regardless of the season, to heat and cool your home or facility.
This type of system can be utilized in new and existing construction, toward both residential and commercial building applications. As described above, the piping provides for a closed-loop system that is leak-free and non-polluting, while additionally allowing the cost of clean geothermal energy to become more comparable to that of gas or oil.

DIY Solar Charger

HoustonUnited States

I created a simple circuit to capture and utilize the energy generated by a single solar cell, in order to charge my phone.

Rural Thermosiphon Water Heating

Puerto NatalesChile

We use a set of thermosiphons to heat water for the camp. The water supply travels through the system, being heated by the energy transferred from the sun to a solar collector. Even in cold areas, solar energy may be harnessed and utilized toward a variety of applications, such as this one.

Hotel Smart Blinds for...

PragueCzech Republic

The blinds in our rooms at Mosaic House have sensors and settings that allow them to automatically adjust themselves in response to changing parameters. There are four primary settings which help us to save energy:

1. Active – Occupied (guest is in the room)

   Electricity: ON

   Temperature of Heating : 21 °C

   Temperature of Cooling: 6 °C higher than outside temperature (default)

– The blinds are in down position and shut. If the guest comes in the room, the blinds open and stay in  the down position

– In case of strong winds, the blinds adjust to the up position

– In the winter season, the blinds also adjust to the up position on sunny days in order to heat up the room

2. Active – Empty (when guest is leaving the room, from 5 min – 4 hrs)

   Electricity: OFF

   Temperature of Heating : 19 °C

   Temperature of Cooling: 2 °C higher than default setting

– The blinds are shut in the down position. If the guest comes in the room, the blinds are opened and stay in the down position.

3. Low Energy (when guest is not in the room, from 4 – 15 hrs)

   Electricity: OFF

   Temperature of Heating : 17 °C

   Temperature of Cooling: 2 °C higher than default setting

– The blinds are in the Active – Empty setting

4. Checked Out / Hibernation (the guest will not be in the room for longer than 15 hrs, or is checked out)

   Electricity: OFF

   Temperature of Heating : 16 °C

   Temperature of Cooling: OFF

– The blinds are in the Active – Empty setting

Renewable Hybrid Power System

NacalaMozambique

Our lodge has constructed an advanced hybrid energy system, using the combined power of solar and wind sources with an assortment of battery banks and a three-phase inverter system. In total, our solar park contains 180 PV modules, and the system altogether may be monitored remotely.

With this, we have also been able to provide additional modules to a local school, and stimulate the community in a number of other sustainable and innovative ways. To date, our system has allowed for 280 MWh of clean electricity, and provides power to the entire lodge, our dive center’s air compressor, and to our water treatment plant. 

Urban University Solar Trash...

HoustonUnited States

To date, the university’s campus features 80 dual recycling receptacles and solar-powered trash compactors. While the compactor takes little space more than an ordinary receptacle, it may hold 5 times the capacity of waste, due to the self-powered compressing process.

This also saves on the amount of labor required to keep up with accumulated trash. BigBelly Solar, the product manufacturer, notes that this can reduce trash collections by up to 80%.

Urban Cool Roof and...

HoustonUnited States

The Houston Permitting and Green Building Resource Centers are housed within a certified LEED Gold building, which incorporates a large variety of sustainable and low-impact features.

Its roof not only supports this large solar installation, but is designed to follow a ‘cool roof code’, as mandated for commercial buildings by the city. The code serves to reduce buildings’ contributions to the heat island effect (a localized increase in temperature around urban areas, created by their everyday activities).

This roof utilizes solar panels (which also act as additional barriers between the sun’s rays and the roof, helping to keep the building cool), as well as exhibiting a light-colored and more reflective roof material, and vegetated green roof on the building’s side. These features give the roof a very high solar reflective index (SRI) of 89/100.
