Are you living in a condo/flat and don’t have any space to grow any herbs or veggies? Don’t worry, we have many ideas on how to help. Here we provide a handful of design solutions that can be easily implemented in your kitchen or living room, on the stairs or window sill, and more.

Standard houseboats – the sun raises indoor temperatures during summer
The houseboats have an lightweight wooden roof construction with a minimum insulation. In the summer the transfer of solar energy dramatically rises the indoor temperature.
Rainwater harvesting represents an alternative water supply that captures and stores rainwater for later use. The harvesting of rainwater is as simple as collecting water from surfaces on which rain falls, and subsequently storing this water for later use. Normally, water is collected from building roofs and stored in dedicated water tanks.
Green roof technology is improving all the time. The goal is to keep the water clean, in some cases probably cleaner than from some traditional roof schemes. Naturally it is necessary to observe the stability characteristics of the sub-structure, the membranes, and the related maintenance requirements.
CAD (Computer Aided Design) is a combination of hardware and software computer technology that enables designers (architects, engineers, etc.) to replace manual drafting with the precision of a digital process capable of creating 2D and 3D models, drawings and plans.
The first known sketch of vertical farms, from Rem Koolhaas in 1909 was presented in his book Delirious New York. In it he talked about the skyscraper “as Utopian device for the production of unlimited numbers of virgin sites on a metropolitan location.” Shortly afterward (1915), G.E. Bailey coined the phrase “vertical farming” and published a book of the same name.
But why is vertical farming getting the importance?
The most important factor in the question of farming and increased vertical farming is world population growth, which is expected to grow from 7 billion people in 2011 to 9 billion in 2045; and whereby 54% of people live in cities today, the UN expects the number to increase to 66% by 2050. In addition: at this rate of population growth total world production of fruits and vegetables will have to rise from the current 2.4 billion tons in 2011 to 3.1 billion tons in 2045 – so the question, understandably, is this: Where will all this food come from?
But first a few words on the history of vertical farming
Before Gilbert Ellis Bailey, PhD invented the phrase “vertical farming” people lived in harmony with nature for thousands of years. Actually, it all started with hanging gardens of Babylon.
In ancient Rome in the year 500, the Romans were growing grapes that climbed walls or wooden structures. Around 1150, the Aztecs were growing food in floating gardens. And in the 15th century the Incas were building forts to support their efforts to bring soil from the valleys to the mountains in order to plant for food.
Some 40 years ago the first truly extensive green roofs were built in Germany. Since then, green roofs have become a common addition to buildings. At the same time, this development has led to a more critical approach to fire safety. Related requirements are becoming increasingly strict, and will continue to evolve as green roof designs develop.
Green roofs should be designed to provide the necessary fire resistance
The first green roof performance tests, including fire tests, were performed and analysed in the 1990s. It’s pretty safe to say that fire safety regulations differ, sometimes significantly, from country to country. So in order to gain a larger global perspective we need to review the way fire safety is treated and talked about on major green roof markets.
After reviewing many cases over the past few years, we can say that generally green roofs should be designed to provide the necessary resistance to the spread of fire by considering 4 primary measures:
Paris is constantly entering into its emergency measures as the city struggles with exceptionally high air pollution levels. Controls on vehicles, free public transport and advice to limit intense sports and avoid large traffic sites at time of high circulation are just some of the measures being taken by the French government to protect residents from the effect of the most prolonged air pollution in the last ten years.
Paris is not the only one; Athens, Madrid and Ljubljana are just some of the Europeans cities currently taking urgent steps to control growing air pollution; a problem which according to the Organisation for Economic Cooperation and Development (OECD) is set to cause as many as nine million premature deaths a year around the world in the next four decades. And the World Health Organisation (WHO) has described this problem as the “world’s largest single environmental health risk”.
Unfortunately, reducing the emission of new air pollutants does not remove those that are already in the air.
In the majority of developed cities, Green Roofs make up about 40–50% of regulated urban surfaces. The quantity of rainwater from these roofs makes a significant contribution to the total volume of water that is channelled into the sewage network. This is the very reason rainwater is one of the main causes of floods in urban environments.
Bioremediation – are you familiar with the process?
Bioremediation is a waste management technique that involves using organisms to remove or neutralize pollutants from a contaminated site.
Bioremediation is a treatment that uses naturally occurring organisms to break down hazardous substances into less toxic or non-toxic substances. It works by providing these pollution-eating organisms with fertilizers, oxygen, and other conditions that encourage their rapid growth.
|Shortly, as remediate means to solve a problem, “Bio-remediate” means to use biological organisms (bacteria, yeast, and fungi), using pollutants as a source of food or in co-metabolism processes to solve an environmental problem. Bioremediation is most commonly used to solve problems related to oil spills or the introduction of various pollutants into the environment and the consequent contamination of groundwater.|
