Интересна работа е ова со фото плочки. Уште ако имаш фирма за слика по нарачка.... ќе има многу луќе занесени што би си отпечатиле портрет на плочките дома! Бизнис бомбона!
ова можеби е за во ПА сепак заради континуитет со погоре постираните слики од инсталациите на Ackroyd & Harvey пост #5, нека оди тука инфото за фото тревниците
I was already excited about Heather Ackroyd and Dan Harvey's grass photographs — because who doesn't love photographs developed using the light-sensitive properties of seedling grass instead of photo paper? — but then I found out they were using special long-lasting genetically modified grass as well. Which makes the pics a whole other category of bio-art, as well as a signpost to the way we may use living matter (instead of dead trees) to reproduce images physically in the future. The Institute of Grassland and Environmental Research in Wales developed a special strain of stay-green grass that can retain images for years, instead of weeks. A few more of my favorite grass photos below the fold.
Chlorophyll prints Binh Dahns photosynthesis process. Binh says: One summer, I was motivated to experiment with photosynthesis and its pigments after watching the lawn change color due to a water hose that was placed on it. Soon after that observation, I was making chlorophyll prints. Photosynthesis takes place in plants as carbon dioxide, water, and light energy is converted to sugars and oxygen. Photosynthesis is the main route by which free energy in the environment is made available to the living world. In my work, photosynthesis is used to record images onto leaves. The leaves are then cast in resin, like biological samples for scientific studies. The images were made into negatives. Then exposed onto living leaves, by placing the negatives onto the leaf, and placing that into a contact printing frame. The image formation was all due to chlorophyll, light, carbon dioxide, and water: the life source of plants and, consequently the Earth. This process deals with the idea of elemental transmigration: the decomposition and composition of matter into other forms.
Grass Art takes center court in a new kind of art installation. UK artists, Heather Ackroyd and Dan Harvey used grass as a photographic paper by projecting a black and white image on it while growing in a dark room.
This installation is Ackroyd and Harvey’s first commercial installation, sponsored by HSBC for the Tennis Championships. The three people featured are Tara Moore, who is competing in the qualifying tournament; Eddie Seaward, the head groundsman at Wimbledon for the last 15 years; and Lizzie May, a coach for the Wimbledon Junior Tennis Initiative. Ackroyd and Harvey first discovered this technique after finishing an installation consisting of a living grass indoor wall. They had a ladder propped against the grass for some time and after removing the ladder they noticed discoloration in a ladder shape. After experimenting with different ways of enhancing this effect, they settled on a method to project a negative image onto the grass. From biology class, you’ll remember that grass needs light in order to produce chlorophyll, which makes it green. The more light it receives, the more green, while the less light it receives, the more yellow the grass is. The picture above is the image projected onto the grass panels in order to achieve the affect of the finished picture. Typically, a grass panel needs a little over a week of exposure at 12 hours per day. Unfortunately, the images don’t last for too long without continued maintenance. Once exposed to natural light, the grass begins to grow more evenly and the images fade away.
To help reduce the increasing urban heat island effect, grass-planted tiles have come in the market - Toyota’s TM9 turf mats. Providing excellent thermal insulation, TM9 roofing tiles will eventually help cool the big modern cities.
While green roofs may be universally accepted as wonderfully sustainable landscapes for a myriad reasons, the thought of installing one atop your own home may nevertheless seem daunting, expensive, and difficult to maintain. But the folks from Toyota Roof Gardens (a subsidiary of the Prius-creating car company) have solved your green roof installation qualms with a tile-based system that’s as easy as laying down carpet. The TM9 self-watering turf tiles measure 20 inches square, and connect directly to irrigation systems, making them entirely self-watering. And at a slim 2 inches thick, the tiles lightweight and do not require any additional structural upgrading to your existing roof, this results in a reduced roof load compared to other types of green roof systems that contain a thicker soil layer.At only $43 per tile, the TM9 system provides a modular, easy-to-install, cost-effective option for green-minded homeowners, for that price they're still expensive, but prices would of course drop if demand were to increase, although this price is still a bargain in terms of reduced installation and maintenance costs, as well as a cost savings if the building’s roof doesn’t need any structural upgrading to account for the increased weight of a conventional green roof. In terms of maintenance, the tiles need only be cut once a year, thanks to a special breed of Korean velvet grass. And of course, like all green roofs, you’ll rest easy knowing that your easy installation is providing a natural cooling effect, thermal insulation, and a little extra flora in your home environment.
This system, as with all green roofs, provides a natural cooling effect as well as excellent thermal insulation for a building. Green roofs can also remove carbon dioxide from the air and supply oxygen, and are an excellent addition to any flat-roofed building. The TM9 turf mat would be an easy way to add a green roof to almost any building. It might even be possible to install the system inside, to make living carpet.
Namba Parks is place where you’ll spend half your time shopping and the other half admiring the design. It stands where Osaka’s baseball stadium used to be until 2003, and consists of a 30-floor skyscraper, Parks Tower, and 120-tenant shopping mall which includes many restaurants and a cinema. The eight floors of terraced gardens, boutique stores, big brands and trendy dining have been an instant hit in shopping-mad Osaka. In addition to providing a highly visible green component in a city where nature is sparse, the sloping park connects to the street, welcoming passers-by to enjoy its groves of trees, clusters of rocks, cliffs, lawn, streams, waterfalls, ponds and outdoor terraces.
sturdy roof structure: Green roofs must typically support 25 to 100 pounds more load per square foot than conventional flat roofs. New roofs, whether made of wood, steel, or concrete, can be designed to support green roofs at minimal additional expense. Existing roofs almost always require costly structural reinforcing.
reliable waterproofing membrane: Leaks in green roofs can be very difficult to identify, and repairs or replacement can be expensive. For a long, maintenance-free life, green roof waterproofing must be sufficiently elastic to withstand building movement, must withstand ponded water, must be non-biodegradable, and must be resistant to root penetration. Some rubber and plastic sheet-applied and liquid-applied membranes meet these criteria but most asphalt products do not.
root-barrier/ponding membrane: If the primary waterproofing system is not resistant to root penetration, it can be covered with a secondary root-barrier membrane. Secondary membranes are also used with some green roof systems where water is intentionally ponded so that the primary waterproofing membrane still drains.
tough protection fabric: A synthetic fabric protects the waterproofing or root barrier/ponding membrane from mechanical damage during construction and roof maintenance. Protection fabrics typically weigh 500 to 900 grams per square meter (15 -27 ounces per square yard). Fabrics with enhanced water storage and capillarity are preferred for some green roof systems.
water-storing drainage layer: It is desirable to store water in green roofs to help plants survive through periods of dry weather. However, the dry-climate plants that thrive on green roofs will not survive unless excess water is rapidly drained from the plant root zone. The optimal combination of water storage and rapid drainage can be provided by several water-storing drainage products including well-graded granular inorganic media, dimpled plastic sheets, and ribbed fabric laminates.
non-clogging separation fabric: For the water storage and drainage layer to function properly, it must be kept free of soil. A synthetic soil separation fabric serves this function, but the fabric must have a structure that resists clogging from fine soil particles such as silts and clays.
engineered soil: Green roof soil is not ordinary soil. It must be lightweight, have good water storage characteristics, have a low organic content, have suitable chemical parameters, and have a good distribution of particle sizes.
appropriate plants: Green roof plants must survive in the green roof environment which if often hot and dry. Thin green roofs usually require sedums and herbs, whereas thicker green roofs can often accommodate a wide range of native plants.
друга опција за пасивно ладење е водата со оглед дека има голем степен на способност за задржување на топлината, пример искористена во кровни базени, шише кровови-ѕидови или распрскувана по кровот... но за постоечки рамни кровови базен или езерце е сомнителна опција заради дополнителната тежина на водата [1] што е до температураната разлика еве тест пример
A building with one space in it was used to test the effect of a roof pond... results showed a marked improvement in the space temperature with a significant reduction during the peak time outside temperatures at 3 O’clock reaching 6.0 °C between the room without the pond and with a ventilated one and 6.5° at 18:00 during peak inside temperatures. The study also showed that improvements would be better in real-life conditions where exterior wall area is less than the test room http://www.sciencedirect.com/science/article/pii/S0360132306004434

The main feature of this house is the swimming pool on the roof, which is used to collect rainwater. The function of storm water to create a natural cooling system because the house is located in a hot climate zone [2] The open-plan of the main house ensures that it is light and airy, a must in the summer. As a secondary precaution, the roof of the building is covered with pools that collect rainwater. The water cascades from the roof of one of the buildings to the other and is then circulated back round, creating a natural cooling system for a hot climate [3]
а еве и по луксузен пример од терасата на хилтон хотелот во патаја [4]
Completed in 1992, this building was a precursor to what we call “green buildings” today. Designed as a headquarters for IBM, the building applies architect Ken Yeang’s bioclimatic designs with both internal and external features to create a low-energy building ideal for a tropical climate. Plantings spiral up the façade and into the skycourts from a three-story-high planted mound. Planting can also be found amongst the triple-height recessed terraces in the upper reaches of the building. These atriums allow natural ventilation with cool air, and the vegetation enhances shade and increases the oxygen supply
