“Idizayini enhle akwanele. Sidinga amakhaya azosifaka ku-net-zero”

Ibhalwe nguGeraldine de Boisse

Ukunciphisa ikhabhoni emissions, architects and designers need to change the way they design amakhaya, writes Geraldine de Boisse, vice president of innovation at renewable-energy supplier Bulb.

“Idizayini enhle akwanele. Sidinga amakhaya azosenza sifinyelele ku-net-zero.”

Indlela esiphila ngayo nesisebenza ngayo isishintshile. While we might not know exactly what normal looks like anymore, we know we need to act now to tackle the climate crisis. And that includes everyone in every industry.

Idizayini enhle ayanele. Sidinga amakhaya namahhovisi azosiyisa inetha-zero. Ukwakhiwa umsebenzi ibalwa kumaphesenti angama-36 okusetshenziswa kwamandla emhlabeni jikelele kanye namaphesenti angama-39 okukhishwa kwe-CO2. Ngakho-ke kubalulekile ebufakazini besikhathi esizayo izakhiwo futhi azenze zibe luhlaza. Lokho kuhlanganisa ukushintsha indlela esiklama ngayo, amandla kanye nokushisisa amakhaya namahhovisi ethu.

Kuze kube manje, iningi lezinzuzo esizenzile ekubhekaneni ne isimo sezulu azizange zithinte izimpilo zabantu zansuku zonke. Ngenxa yokwanda okukhulu kwe amandla avuselelweko, manje esenamandla cishe ngamaphesenti angama-30 amakhaya ase-UK uma kuqhathaniswa nephesenti elilodwa ngo-2015, amazwe amaningi akwazile ukunciphisa ukukhishwa kwegesi ngaphandle kokuphazamisa indlela esiphila ngayo.

Izinzuzo esizizuzile ekubhekaneni nenkinga yesimo sezulu azizange zithikameze izimpilo zabantu zansuku zonke

Isigaba esilandelayo sizodinga ushintsho lomuntu siqu, futhi ohulumeni banendima ebalulekile okufanele bayidlale ekumiseni inqubomgomo kanye nezisusa zezezimali. Ukufinyelela izinhloso zeSivumelwano saseParis ngo-2050, amakhaya akhona azodinga ukubuyiselwa okujulile including better insulation, upgraded windows, heat pumps, solar panels and electric vehicle chargers. New homes will feature these as standard.

Lokhu kusho ukuthi amakhaya azobukeka ehlukile esikhathini esizayo, okudinga izindlela ezihlukene zokuklama. Abaklami bazodinga ukucabanga ngobuciko mayelana nendlela yokuhlanganisa le mikhiqizo emisha.

In the UK, from 2025, no new gas boilers will be installed in new UK homes; instead, we’ll move towards using electricity for heating. Heat pumps, popular in several Nordic countries as well as the US, will become commonplace. It’s important to factor this in when drawing up new plans for properties.

We’ll see more people generating their own electricity using solar panels, and storing it in electric car batteries, or home batteries. More people will sell electricity back to power grids when demand is highest. At Bulb, we’re trialling home battery technology for our members with solar panels. Designs will need to incorporate ways for people to generate, manage and store their own power.

Emhlabeni jikelele, ukushisa kubala cishe ingxenye yawo wonke amandla asetshenziswayo

Insulation will have to get better. Without good insulation, heat escapes from roofs, floors and walls, increasing the amount of energy needed to heat buildings. Globally, heat accounts for nearly half of all energy consumption and almost 40 per cent of carbon emissions from energy. While ukwahlukanisa kungafakwa ezakhiweni ezintsha, ukulungisa kabusha amakhaya amadala kuyabiza futhi kuyaphazamisa, ngakho ohulumeni kudingeka banikeze izikhuthazo ezingcono zezimali, njengokuchitha i-VAT emikhiqizweni eluhlaza.. For new builds, designs should optimise energy efficiency and maximise insulation.

Ishintshela ku amandla avuselelweko is the fastest and cheapest way to lower your CO2 impact at home or in the office. It could lower your carbon emissions by 3.2 tonnes of carbon a year at home and reduce your business’ emissions by around 40 per cent.

Okulandelayo, buza umhlinzeki wakho wamandla ukuthi uyafaneleka yini ukufakwa imitha ehlakaniphile ekhaya noma ehhovisi. Amamitha ahlakaniphile asiza ukwehlisa izikweletu futhi anciphise ukukhishwa kwekhabhoni. Amamitha ahlakaniphile akhombisa lapho usebenzisa khona amandla amaningi, ukuze ukwazi ukuthatha izinyathelo zokuwehlisa.

Isenzo esilula sokwenqaba isenzo se-thermostat singanciphisa izikweletu zakho kanye nokukhishwa kwekhabhoni yakho

Uma ulungisa kabusha ingaphakathi, kubalulekile ukulungisa izikhala okuzosho ukuthi uyakwazi ukunciphisa ikhabhoni futhi wenzele iplanethi yakho kancane. Ukuba nedeski lakho eduze kwefasitela kude nelanga ehlobo kuzosho ukuthi akudingeki usebenzise izifeni noma okomoya; ukubeka osofa nezihlalo kude nama-radiator ebusika kuzovumela ukushisa okuvela kurediyetha yakho ukufudumala igumbi lonke, kunokuba nje ingemuva lefenisha.

Futhi ukufaka i-insulation kuzogcina ikhaya lakho noma ihhovisi lifudumele ebusika futhi lipholile ehlobo, kanye nokunciphisa izikweletu zakho zamandla kanye nokunciphisa ukukhishwa kwekhabhoni yakho. Ungabheka nokushintsha amafasitela nezicabha, noma ukushintshela iphampu yokushisa.

Kungakhathaliseki ukuthi usekhaya noma ehhovisi, isenzo esilula sokwenqaba isenzo se-thermostat singanciphisa izikweletu zakho kanye nokukhishwa kwekhabhoni yakho. Ukwehlisa i-thermostat yasehhovisi ngamadigri amabili nje kuzokonga u-£140 ebhilidini engu-£1,000, futhi ngokwehlisa i-thermostat yakho ekhaya ngedigri eyodwa, ungonga cishe u-£90 ngonyaka. Noma thola i-thermostat ehlakaniphile, ezovumelana nendlela othanda ngayo ukushisa ikhaya lakho futhi ikubonise izinga lokushisa elisebenza kahle kakhulu.

Lapho ukhetha ukukhanyisa, kukhona iqhinga lokuqinisekisa ukuthi awumoshi amandla futhi awusebenzi ngendlela okhetha ngayo ukukhanyisa: Izibani ze-LED zisebenza kahle ngamaphesenti angu-65 kunokukhanyisa okuvamile. Ungaphinda ugweme ukukhanyisa amagumbi angenalutho ngokusebenzisa izinzwa zokuhlala. Faka izinzwa zasemini ukuze ufiphale izibani ngokuzenzakalelayo ezindaweni ezikhanyayo noma ezingaphandle, futhi uma ucabanga ngokulungisa, cabanga ukuhlukanisa izibani kumasekhethi amancane anamaswishi amaningi. Lokhu kukunikeza ukuguquguquka okwengeziwe kokuhlukanisa isikhala sakho ezindaweni ezihlukene, futhi ube nezibani ezimbalwa ezikhanyayo.

Ukuze kuzuzwe i-net-zero, zonke izinhlaka zezimboni zidinga ukuhlangana ndawonye futhi zidlale indima yazo

If you’ve already switched from a diesel or petrol car to an electric one then well done – you’re already doing your bit to reduce your carbon footprint. You can go one step further by charging your car at the cheapest, greenest time of the day. At Bulb, we’re trialling EV technology that allows you to order a stylish home charger, connect your car to our app, and automatically charge when demand is lowest on the grid.

Ukuze kuzuzwe i-net-zero, zonke izinhlaka zezimboni zidinga ukuhlangana ndawonye futhi zidlale indima yazo. Emhlabeni wokuklama, kunethuba lokulinganisa idizayini enhle nokusebenza kahle kwamandla kumabhilidi angenabufakazi besikhathi esizayo. I ikusasa lezindlu nezakhiwo zizohluka, kodwa zibe ngcono. Sisesikhathini esibalulekile manje lapho abaklami bedinga ukungena khona. Ezweni lanamuhla, akukhona nje ukuba nengaphakathi elihle; ukusimama kufanele ibeke kuqala.

Note by Constructive Voices editor:

Nasi isibonelo esithakazelisayo samakhaya angasebenzeli nje kuphela ku-net-zero kodwa futhi ayingxenye yesixazululo se- ukushoda kwamakhono ukuba nolwazi emazweni amaningi.

Inguquko yekhabhoni

Lesi sihloko siyingxenye ye-Dezeen's i-carbon Revolution uchungechunge, oluhlola ukuthi le nto eyisimangaliso ingasuswa kanjani emkhathini futhi isetshenziswe emhlabeni. Funda konke okuqukethwe ku: www.dezeen.com/carbon.
