A Passive House is a building designed like a thermos: carefully sealed, insulated and ventilated so it wastes very little energy.

The story behind the card

Passive House is a performance standard, not an architectural style: any building that meets its measured limits can qualify. The idea grew from a 1988 conversation between Bo Adamson of Lund University in Sweden and the German physicist Wolfgang Feist. Four terraced houses built in Darmstadt-Kranichstein, Germany, in 1990–91 are usually cited as the first examples. Feist founded the Passivhaus Institut in Darmstadt in 1996 to certify buildings. The best-known limits are a yearly heating demand of no more than 15 kilowatt-hours per square metre of floor, and an airtightness test in which a fan pressurises the building and no more than 0.6 of its volume of air may leak out in an hour. Fresh air comes in through a ventilation unit that warms it with the heat of the stale air going out.

Pasif Ev, termos gibi düşünülmüş bir binadır: Kalın yalıtımı, hava sızdırmayan kabuğu ve ısıyı geri kazanan havalandırmasıyla çok az enerji harcar.

Pasif Ev bir mimari tarz değil, bir performans standardıdır: Ölçülen sınırları tutturan her bina bu adı alabilir. Fikir, 1988'de İsveç'teki Lund Üniversitesi'nden Bo Adamson ile Alman fizikçi Wolfgang Feist arasındaki bir konuşmadan doğdu. Almanya'nın Darmstadt-Kranichstein semtinde 1990–91'de yapılan dört sıra ev, genellikle ilk örnekler sayılır. Feist, binaları belgelendirmek için 1996'da Darmstadt'ta Passivhaus Enstitüsü'nü kurdu. En bilinen iki ölçüt şunlardır: Yıllık ısıtma ihtiyacı metrekare başına en fazla 15 kilovatsaat olmalıdır; bir fanla basınç uygulanan binadan bir saatte, içindeki hava hacminin en fazla 0,6 katı kadar hava kaçabilir. Temiz hava, dışarı atılan bayat havanın ısısıyla ısıtılarak içeri veren bir havalandırma cihazından gelir.

A windcatcher, badgir in Persian, is a tall tower on a roof that catches passing breezes and channels them down into the rooms below. It has cooled houses in hot, dry places such as Iran for centuries, without any machinery.

The top of the tower has openings that face the wind. Air pushed in is forced down a shaft into the house, while warm air leaves through openings on the sheltered side; on still days the sun-warmed tower works like a chimney and draws air through the rooms. Yazd, a desert city in central Iran listed by UNESCO in 2017, is famous for its many windcatchers, and the one in its Dowlatabad Garden, about 33 metres high, is often described as the tallest in the world. Paired with covered water reservoirs called ab-anbars, windcatchers helped keep drinking water cool. Similar towers are found from Egypt to the Persian Gulf, and architects now study them for low-energy cooling.

Angkor, capital of the Khmer Empire in today's Cambodia from the ninth to the fifteenth century, was ringed by giant reservoirs, moats and canals that stored monsoon rain and moved water across an urban area of about 1,000 square kilometres.

The largest reservoirs, called barays, are vast rectangles banked with earth: the West Baray, built in the eleventh century, measures about eight kilometres by two and still holds water. Moats such as the one around Angkor Wat framed temples modelled on the sacred mountain and surrounding oceans of Hindu and Buddhist cosmology. Radar and aerial surveys published in 2007, and airborne laser scanning (lidar) that saw through the forest in 2012, revealed roads, canals and house mounds across at least 1,000 square kilometres, the largest known pre-industrial settlement. Researchers still debate how much the barays watered rice fields. Tree rings show long droughts broken by intense monsoons in the fourteenth and fifteenth centuries, which damaged the network and probably contributed to Angkor's decline.

Cities are often a few degrees warmer than the countryside around them, an effect called the urban heat island. Asphalt, concrete and dark roofs soak up the sun's heat and give it back slowly, while streets without trees get no shade.

The effect was first described in the 1810s by Luke Howard, a London manufacturing chemist and amateur meteorologist, who found that the centre of London stayed about 2°C warmer at night than the surrounding countryside. In the United States, the Environmental Protection Agency puts the typical difference at roughly 0.5 to 4°C by day and 1 to 3°C at night. The gap is often widest after dark, when concrete and asphalt release the heat they stored during the day. Cities respond with pale, reflective pavements and roofs, green roofs and street trees, because shade and light-coloured surfaces measurably lower local temperatures. The heat also falls unevenly: neighbourhoods with fewer trees and more paving are usually the hottest.

A qanat is an underground channel, developed in ancient Persia, that brings groundwater from the foot of hills to fields and towns using gravity alone. From above, a qanat shows as a line of shaft openings across dry land.

Builders start with a 'mother well' dug down to the water table, then cut a tunnel back towards the surface on a very gentle slope, so the water flows without wearing away the channel. Vertical shafts along the route let workers lift out soil, bring in air and later clean the tunnel. The Qasabeh qanat at Gonabad in eastern Iran, dated to between 700 and 500 BCE, has a mother well more than 360 metres deep and about 33 kilometres of channels, and still carries water. In 2016 UNESCO listed eleven Iranian qanats together as a World Heritage site, recognising both the engineering and the old customs for sharing the water fairly.

When Syria's civil war cut the agricultural research centre ICARDA off from its genebank near Aleppo, it turned to the backup seeds it had stored in the Svalbard Global Seed Vault in Arctic Norway. Those seeds were used to rebuild its collections in Lebanon and Morocco.

ICARDA, the International Center for Agricultural Research in the Dry Areas, kept one of the world's major collections of wheat, barley, lentil and other crop varieties at Tel Hadya, near Aleppo. A genebank stores seeds alive for plant breeders and researchers, and between 2008 and 2014 ICARDA sent duplicates of 116,484 samples to Svalbard. The vault, opened in 2008, is dug into a mountain on an Arctic island and keeps seeds frozen at about minus 18°C. ICARDA withdrew seeds in 2015, the first withdrawal in the vault's history, and again in 2017 and 2019, until every sample had come back. Once the seeds had been grown again in Lebanon and Morocco, fresh duplicates were returned to Svalbard.
