Craig Applegath dan Proyek Kayu Massal Tanpa Karbon

In 2022 Q2, we will be speaking to Craig Applegath, architect, urban designer, and zero-carbon building pioneer, on the Constructive Voices Podcast.

Craig has an impressive career that has seen him internationally recognised for his design and advocacy of zero-carbon regenerative buildings and cities, as well as mass timber design.

Training first as a biologist at the University of Toronto, before completing a Master’s of Arsitektur in Urban Design at Harvard University. This amalgamation of biology and architecture has driven Craig’s passion for planning and design solutions that make sense in a world challenged by climate change and environmental deterioration.    

Craig is a founding partner of DIALOG’s Toronto studio, where his role includes master planning and designing institutional projects like higher education and healthcare facilities, such as the recent Centennial College Zero-Carbon Mass Timber project.

Proyek Kayu Massal Nol Karbon Centennial College

Centennial College Zero-Carbon Mass Timber Project adalah gedung pendidikan tinggi kayu massal yang terinspirasi dari masyarakat lokal. Penambahan enam lantai akan menyediakan ruang program akademik seluas 150,000 kaki persegi untuk School of Teknik Technology and Applied Science programs. The design for the expansion was based on the Indigenous concept of “two-eyed seeing,” in which people view the world through an Indigenous lens with one eye or perspective, while the other eye sees through a Western lens.

Membawa proyek Kayu Massal Tanpa Karbon ini ke tingkat yang baru, secara harfiah, Craig terlibat dalam prototipe Menara Kayu Hibrida “Supertall” DIALOG, di mana keseluruhan penggunaan kayu yang dipanen secara berkelanjutan dimaksimalkan dalam menara yang sangat hemat biaya, hemat energi, dan elegan. .

"Menara Kayu Hibrida Super Tinggi

The “Supertall” Hybrid Wood Tower, at 105-storeys tall, was designed to showcase the potential of mass timber in improving both building sustainability and overall design and to challenge the belief that tall buildings cannot be zero carbon.

The “Supertall” Hybrid Wood Tower is among the most technically challenging structures to design, but it’s also a perfect typology for testing the limits of sustainable mass timber design and zero carbon design.

Desainnya fleksibel sehingga calon mitra pengembangan dapat menyesuaikan parameter dan elemen desain, seperti tinggi dan pelat lantai, agar sesuai dengan lokasi tertentu. Sistem panel lantai kayu hibrida yang dipatenkan menggunakan batang baja untuk menambah kekuatan tarik pada panel kayu laminasi silang pra-fabrikasi untuk dinding bangunan. Artinya dinding bisa menopang beban tambahan.

The environmental sustainability of the building has many elements. One of the main ones is the carbon-capturing ability of wood itself. The photosynthesis process requires carbon in order to grow trees, meaning wood construction removes carbon from the atmosphere and holds it within the building. A building constructed to the exact specifications of DIALOG’s pitch would store more than 36,000 tons of carbon. 

Fotovoltaik terintegrasi pada fasad selatan, timur, dan barat dapat memasok listrik untuk gedung dengan penyimpanan baterai untuk daya tambahan yang dihasilkan selama jam-jam di luar jam sibuk. 

Desain bangunan ini juga mencakup bioreaktor alga. Reaktor ini berukuran 1,500 meter kubik yang menggunakan emisi karbon untuk membudidayakan alga. Alga dapat digunakan sebagai sumber pendapatan sekunder untuk makanan manusia atau hewan, biofuel, dan produk lainnya. Reaktor ini akan mampu menyerap semua emisi berlebih, menjamin bangunan yang netral karbon.

Untuk memperhitungkan pengaruh angin pada bangunan tinggi, struktur tersebut dibentuk secara ortogonal, melengkung perlahan hingga bertemu dengan tanah, menyampaikan bagaimana beban dibawa ke tanah. Hal ini mengingatkan kita pada bagaimana batang pohon melakukan tugas yang sama seperti ketika memenuhi bumi.

Imperatif Abad Kedua Puluh Satu Podcast

Craig also hosts the Twenty First Century Imperative, a podcast that explores the question of how we will continue to live on our planet without destroying our biosphere. The podcast series that explores the insights, approaches, experiences of change-makers from various backgrounds, who are finding smart, effective ways to answer one or more of the three critical challenges of the Twenty First Century Imperative:

1. Bagaimana kita bisa terus hidup di planet kita tanpa merusak biosfer kita?
2. Bagaimana kita memperbaiki dan memulihkan kerusakan lingkungan yang telah kita timbulkan?
3. Bagaimana kita bisa berhasil beradaptasi terhadap dampak perubahan iklim yang semakin meningkat?

Craig also writes, speaks and teaches about his research and design explorations at conferences and workshops internationally, including the UN Habitat III Conference in Prague, the World Future Council Conferences in Munich and Beijing, at the International Living Futures Institute Conference in Portland, and most recently, at the Konferensi Mahasiswa Institut Arsitek Amerika di Toronto.
