Eco Friendly

self su Self-sustainabilty is key to thePharm. Using a series of cutting edge green technologies, the pharm is able to generate its own electricty through use of an off site wind farm. This system alone can generate enough electricity to power thePharm for a full year, whilst generating surplus electricity that can be sold back to the grid.

Along with providing its own electricity, thePharm is fitted with a series of ‘Eco Friendly Gadgetry’ such as a double skin wall that alows for hot air to be stored between walls that can be quickly flushed around or out of the building. Another key feature is the galvanized steel light shelves that fit on the exterior of the building. These shelves twist with the direction of the sun allowing light from all angles to enter inside the building. Natural sunlight provides the plants with a much more intense spectrum of light allowing the to grow even faster and bigger than under conventional indoor lamps.

Wind turbines come in a wide variety of shapes and sizes, ranging from vertical-axis eggbeaters and cycloturbines to more conventionally shaped horizontal-axis turbines with single to multiple blades. The traditional American farm windmill, for example, is a multi-bladed horizontal axis turbine. Horizontal axis turbines are further categorized by rotor size, which can indicate a ballpark range of energy generated. Small triple-rotor turbines approximately one to four meters in diameter can generate up to one kW of power in winds ranging from 6 to 30 m/s (13 to 65 miles per hour). These turbines may be used for low- demand activities such as recharging batteries aboard sailboats or powering a small house. On the other end of the spectrum, giant experimental turbines such as the world’s largest, in Germany, have a rotor diameter of up to 100 meters, and they can generate upwards of 3 MW of power apie

Solar panels, also known as photovoltaic panels, convert sunlight to any form of electrical energy. Only about 4 – 22% of the energy falling on a solar panel is converted into usable electrical energy. The efficiency is quite low because the rest of the solar light is reflected back or dissipates as heat. On the up side, however, solar panels can be converted into any type of electrical energy necessary.

Solar panels are dependent on the time of day, the time of year, the temperature, and the angle of sunlight as well as the albedo effect (reflection of sunlight from clouds). As a result, the reliability of power harnessed from the panels is potentially problematic, wherein a system that relies on enough electricity to meet specific needs may not respond when such energy is in at the lowest point during the evening or winter periods, for example. On the other end, solar panels can overload a system during times of intense sunlight. One solution for this problem is utilizing the energy for a use that somewhat parallels the natural ebbs and flows of the energy gained from the sun. One such system is using solar panels for air conditioning purposes. In the circumstance that the building is largely comprised of windows, a large greenhouse effect especially during the summer period, air conditioning necessities will be somewhat proportional to energy gleaned from the solar panels. Therefore, recommendations for solar panels are their usage for air conditioning purposes.
