IntroductionWhat is LEED?

BenefitsCostsResourcesIncentivesGlossary

Green building is not a simple development trend; it is an approach to building suited to thedemands of its time, whose relevance and importance will only continue to increase. The benefitsto green building are manifold, and may be categorized along three fronts: environmental,economic, and social.Green building bukanlah tren pengembangan sederhana, itu adalah sebuah pendekatan untuk

membangun sesuai dengan tuntutan zamannya, yang relevansi dan pentingnya hanya akan terusmeningkat. Manfaat untuk membangun hijau banyak ragamnya, dan dapat dikategorikansepanjang tiga bidang: lingkungan, ekonomi, dan sosial.

Environmental Benefits

Emissions Reduction. Pollutants released by fossil fuel fired electricity contribute toglobal climate change, cause air quality issues such as acid rain and smog, and pose risksto human health.1Green building techniques like solar powering,daylighting, andfacilitation of public transport increase energy efficiency and reduce harmful emissions.

Pengurangan Emisi. Polutan yang dilepaskan oleh bahan bakar fosil menembakkan listrikberkontribusi terhadap perubahan iklim global, menyebabkan masalah kualitas udaraseperti hujan asam dan kabut asap, dan menimbulkan risiko bagi kesehatan manusia. 1teknik bangunan hijau seperti surya powering, pencahayaan, dan fasilitasi peningkatanefisiensi energi transportasi publik dan mengurangi emisi berbahaya

Water Conservation. Recycling rainwater andgreywaterfor purposes like urinal flow

and irrigation can preserve potable water and yield significant water savings. Konservasi Air. Daur ulang air hujan dan greywater untuk tujuan seperti aliran urinoir dan

irigasi dapat melestarikan air minum dan menghasilkan penghematan air yang signifikan.v

Stormwater Management.Stormwater runoffcan cause waterway erosion, flooding,and carry pollutants into water sources. Harvesting and redirecting stormwater, buildingsurfaces with permeable materials, and usinggreen roofscan control and utilizeoverflow.

membangun permukaan dengan bahan permeabel, dan menggunakan atap hijau dapatmengendalikan dan memanfaatkan overflow.

Temperature Moderation. The heat retention properties of tall buildings and urban

materials such as concrete and asphalt are the primary causes ofurban heat island effect.These conditions may be offset by conscientious building design and site selection, aswell as planting trees to accompany new developments.

Moderasi Suhu. Sifat-sifat retensi panas dari gedung-gedung tinggi dan bahan perkotaanseperti beton dan aspal adalah penyebab utama efek pulau panas perkotaan. Kondisi inidapat diimbangi dengan desain bangunan teliti dan pemilihan lokasi, serta penanamanpohon untuk menemani perkembangan baru.

Waste Reduction. Construction and demolition generates a huge portion of solid waste

in the United States. Buildingdeconstructionas an alternative to full-scale demolition

results in massive decreases of waste production.2 Pengurangan Limbah. Konstruksi dan pembongkaran menghasilkan sebagian besar limbah

padat di Amerika Serikat. Bangunan dekonstruksi sebagai alternatif untuk skala penuh hasil

pembongkaran dalam penurunan besar produksi limbah. 2

Economic Benefits

A common impression about green building is that thegreen premiumis too expensive to beconsidered economically feasible. However, studies have shown that the costs of green buildingsare not substantially higher than regular development projects.3Higher construction costs cangenerally be avoided by the inclusion of green design from the outset of the project.4

Additionally, green buildings provide an assortment of economic advantages.

Sebuah kesan umum tentang green building adalah bahwa premi hijau terlalu mahal untukdianggap layak secara ekonomis. Namun, penelitian telah menunjukkan bahwa biaya bangunanhijau tidak secara substansial lebih tinggi dari proyek-proyek pembangunan biasa. 3 biayakonstruksi lebih tinggi pada umumnya dapat dihindari dengan dimasukkannya desain hijau dariawal proyek. 4 Selain itu, bangunan hijau menyediakan berbagai macam keuntungan ekonomi

Energy and Water Savings. The resource efficiency provided by green design andtechnology leads to drastic reductions in operation costs that quickly recoup anyadditional project costs5and continue to offer dramatic long-term savings (see statistics).Money previously directed toward utility costs may be used for other purposes.

menumbuhkan bakat-bakat lokal: desainer dan pembangun berpengalaman denganproyek hijau mampu mengakomodasi permintaan pasar yang berkembang untukpembangunan berkelanjutan.

Social Benefits

Improved Health. Poor indoor environmental quality (IEQ) resulting from insufficientair circulation, poor lighting, mold build up, temperature variances, carpeting andfurniture materials, pesticides, toxic adhesives and paints, and high concentration ofpollutants (typically 10 to 100 times higher than outdoors11) contribute widely to

respiratory problems, allergies, nausea, headaches, and skin rashes. Green buildingemphasizes ventilation and non-toxic,low emitting materialsthat create healthier andmore comfortable living and working environments.

Peningkatan Kesehatan. Kualitas lingkungan yang buruk indoor (IEQ) akibat sirkulasiudara cukup, pencahayaan yang buruk, jamur membangun, variasi suhu, karpet danbahan furnitur, pestisida, perekat dan cat beracun, dan konsentrasi polutan tinggi(biasanya 10 sampai 100 kali lebih tinggi dari outdoors11) berkontribusi secara luasuntuk masalah pernapasan, alergi, mual, sakit kepala, dan ruam kulit. Bangunan hijaumenekankan ventilasi dan tidak beracun, bahan memancarkan rendah yang menciptakankehidupan yang lebih sehat dan lebih nyaman, dan lingkungan kerja.

Improved Schools. An estimated 40% of schools in the United States are subject to poor

environmental conditions that compromise the health and learning of students.12Thehealthier environment and atmosphere in school buildings utilizing green design andconstruction principles is shown to lead to significant reductions in student absenteeism13and improvements in test scores (see statistics).14

Peningkatan Sekolah. Diperkirakan 40% dari sekolah di Amerika Serikat tunduk padakondisi lingkungan yang buruk yang membahayakan kesehatan dan belajar siswa. 12Lingkungan sehat dan suasana di gedung sekolah menggunakan desain hijau dan prinsip-prinsip konstruksi terbukti menyebabkan penurunan yang signifikan pada absensimahasiswa 13 dan perbaikan dalam skor tes (lihat statistik).

Healthier Lifestyles and Recreation. A key element of sustainable design is the

preservation of natural environments, which afford a variety of recreation and exerciseopportunities. Green buildings also seek to facilitate alternatives to driving, such asbicycling and public transport, which eases local traffic while encouraging personalhealth and fitness.
