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

Building Energy Setup and...

Ville de QuebecCanada

In the foregound, we have a buffer tank for our geothermal circuit. Pumps circulate glycol in the mitigated circuit between the heat pumps. In the background, two water heaters are used to power the restaurant. Just like the rest of the building mechanics, everything is controlled by the building-management computer system. The central computer cycles the start-up of various equipment and uses load shedding to reduce the electricity demand peaks as much as possible.

The next image displays an overview of the complexity of the piping. The cabinets at the bottom are water-to-water heat pumps which allow the surplus heat to be sent to the geothermal wells during the air conditioning period, and to draw heat to the restaurant in very cold weather.

City Solar Parking Kiosk

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

LEED Gold Stadium Renewable...

PhiladelphiaUnited States

The Philadelphia Eagles football stadium has embraced a number of sustainability practices in its overall operations, along with gaining a LEED Gold Certification from the US Green Building Council.

As part of this, the stadium utilizes solar panel installations on several areas of its structure and throughout the north public parking area, which is lined with solar canopies. There are reportedly 11,108 solar panels used. Fourteen wind turbines also line the top of the stadium.

These technologies provide approximately 1/3 of the stadium’s energy, creating 4 MW per year. More can be read on Lincoln Financial Field’s energy practices and usage here:

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.

DIY Solar Charger

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

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:

EcoCamp Renewable Energy Sources

Puerto NatalesChile

Our camp creates energy where it can, utilizing both solar and hydro sources. Using solar panels, we are able to provide around 30% of our power needs. However, the other 70% is made available through a micro-hydro turbine, powering our appliances and lighting. The flow of the river is able to provide a steady 800 W to us, with an input of 5 liters per second and high net pressure.

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. 

Building Indoor Solar Faucets

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.
