Urban Hotel Rooftop Solar...

PragueCzech Republic

The solar panel installation at our hotel can be seen at the center right of the image, and utilizes the sunlight as a source of energy to heat running water. The temperature of the working fluid can rise up to 80°C. Thanks to our Pontos, cooling, and boiler systems, the running water is then cooled to 55°C by the end of the whole process.

In the summer season, there is no need to activate the Pontos or boiler systems, as the solar panels absorb enough sun energy (up to 240 kW) to warm up the running water.

More information on the Mosaic House Pontos system may be read in another post:

Building Indoor Solar Faucets

HoustonUnited States

I have seen a few installed Sloan solar faucets, which use the ambient INDOOR light to power the faucet sensor, turning it on and off automatically.

Solar Public Art Installation

AustinUnited States

These installations are named ‘SunFlowers – An Electric Garden’. They are stunning, and line the entrance to a local shopping center in the Mueller community of Austin, Texas.

Urban Solar Parking Canopies

AustinUnited States

These solar canopies for parking lots not only help to provide electricity, but offer shade, rooftop protection, an efficient use of the substantial area allocated for parking space, and the option to introduce and power electric vehicle charging stations directly where they are needed.

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.

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.

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).

Urban Solar Trail Lighting

MiamiUnited States

Our local park has solar panels that are used to power the trail lighting. There are about 40 individual installations, and we believe the lamps act on a light sensor that operates using standard dusk till dawn settings.

A line of vertical axis (VAWT) turbines on the A&M Corpus Christi campus.

LEED Home Rooftop Solar...

HomeUnited States

This LEED Platinum home plot exhibits a large variety of sustainable features, including this 30-panel solar installation atop the barn roof. The setup involves a 6.9 kW system, which serves to power roughly 1/3 of the plot’s operations (covering three buildings and a pond).

In addition, with the aid of supportive credits, the cost of the system was able to be reduced a great deal, to half of the overall total.

University “Solar Garden” Installation

These solar flowers were co-designed by students from UT Martin’s Engineering and Visual Arts departments.

City Solar Parking Kiosk

HoustonUnited States

Our city has solar panels on all of the parking kiosks.

University Solar Emergency Call...

HoustonUnited States

Our campus features scattered emergency call boxes that are powered by solar panels.

Large Rural Texas Wind...

West TexasUnited States

The Roscoe Wind Farm is one of the largest wind farms in the world, with over 600 operational turbines spread over 400 km2 of land, producing nearly 800 MW of energy, to date.
