"Summary: "As an architect, you want to integrate the best building envelope construction methods, materials science, and structural principles in your work, but you need a resource to help you. With more than seventy significant case studies located in North America, South America, Europe, and Asia from prehistory to the present, this book illuminates the theory and techniques of assembling exteriors. Six chapters organized by wall types, from hand-set monolithic walls to digitally fabricated curtain walls, each have a material focus section to help you understand their intrinsic properties so that you can decide which will best keep the weather out of your building. Case studies include: Great Wall, China Israeli Supreme Court Building, Jerusalem, Ram Karmi and Ada Karmi-Melamed Fďřation Nationale du Bt́iments, Paris, Jean Prouv ̌Institut du Monde Arabe, Paris, Jean Nouvel Morgan Library, New York City, Renzo Piano Katsura Imperial Villa, Kyoto Sainsbury Center for Visual Arts, Norwich, UK, Sir Norman Foster""

"Tesis ini bertujuan untuk menemukan alternatif selubung bangunan pada bangunan yang berada tepat di garis khatulistiwa. Hal ini dilakukan melalui beberapa eksperimen agar memenuhi nilai OTTV yang sesuai dengan SNI 6389:2020, yaitu Konservasi Energi Selubung Bangunan pada Bangunan Gedung. Bangunan yang diteliti pada penelitian ini adalah bangunan Perpustakaan Universitas Tanjungpura di Kota Pontianak, dengan orientasi bangunan menghadap arah timur laut. Perpustakaan Universitas Tanjungpura memiliki banyak bukaan tanpa pelindung pada sisi terpanjang bangunan, sehingga cahaya dan panas matahari langsung mengenai selubung bangunan. Dari hasil perhitungan nilai OTTV yang telah dilakukan, nilai OTTV bangunan Perpustakaan Universitas Tanjungpura tinggi yakni 63,48 Watt/m2, melebihi SNI 6389:2020 yaitu maksimum 35 W/m2.Penelitian ini memberikan rekomendasi selubung bangunan pada bangunan Perpustakaan Universitas Tanjungpura yang tepat dan sesuai, agar dapat mengurangi nilai OTTV selubung bangunan. Tulisan ini menggunakan pendekatan kuantitatif yang dilakukan dengan mengumpulkan data melalui observasi, studi literatur, dan studi dokumen. Hasil penelitian menunjukkan bahwa ada potensi untuk mengurangi nilai OTTV dengan eksperimen-eksperimen yang telah dilakukan pada bangunan Perpustakaan Universitas Tanjungpura.

This paper aims to find an alternative building envelope in the building located in territory passed by the equator. The alternatives are done through several experiments to meet the OTTV value according to SNI 6389:2020, namely Energy Conservation in Building Envelopes. The building studied in this study is the Library Building of Tanjungpura University in Pontianak City, with the orientation of the building facing the northeast. Tanjungpura University library has many unprotected openings on the longest side of the building, so the light and heat from the sun directly hit the building envelope. From the OTTV value calculation results that have been carried out, the OTTV value of the Tanjungpura University library building is high, that is 63,48 Watt/m2, exceeding SNI 6389:2020, which has a maximum value of 35 Watt/m2.

The study provides appropriate and suitable recommendations for the Tanjungpura University library building envelopes to reduce the OTTV value of the building envelopes. This paper used quantitative approaches by collecting data through observation, literature and document study. The results show a potential to reduce the OTTV value through experiments that have been carried out in the Tanjungpura University library building. "

"Sektor rumah tangga adalah konsumen energi terbesar di Indonesia. Instrumen yang menggunakan energi paling besar pada sektor ini adalah sistem penyejuk udara sebagai akibat dari iklim tropis Indonesia yang membuat temperatur udara lebih tinggi daripada temperatur standar kenyamanan termal. Phase change material (PCM) berpotensi mengurangi konsumsi energi dengan menurunkan besar envelope heat transfer rate yang masuk ke dalam bangunan. Pemilihan PCM serta konfigurasi integrasinya dengan material bangunan krusial dalam menentukan performanya. Pemilihan didasarkan pada kondisi iklim tempat pengaplikasian PCM. Penelitian ini akan menguji performa termal beberapa PCM yang diintegrasikan dengan material bangunan bata beton ringan memanfaatkan simulasi numerikal pada peranti lunak EnergyPlus. Integrasi material bangunan bata beton ringan dengan satu jenis PCM bernama RT 35 yang diproduksi oleh Rubitherm Technologies GmbH, menghasilkan reduksi envelope heat gain transfer rate paling baik. Konfigurasi integrasi yang menempatkan PCM pada lapisan tengah material bangunan memiliki performa yang lebih baik jika dibandingkan konfigurasi yang menempatkan PCM pada lapisan luar serta dalam tembok bangunan. Hal tersebut terjadi karena penempatan PCM pada lapisan tengah memberikan perbedaan temperatur PCM yang lebih rendah dengan sekitarnya. Analisis sifat termal terhadap PCM RT 35 dengan ketebalan 20 mm yang ditempatkan pada lapisan tengah menghasilkan peningkatan hambatan termal tembok sebesar 0,141 m2-K/W.

Household sector consumes the largest amount of energy compared to other sectors in Indonesia. The most consuming instrument is the air conditioning (AC) system as the tropical climate of Indonesia yields outdoor temperature that is higher than the standardized temperature for thermal comfort. Phase change material (PCM) possesses potential to reduce the employment of energy for the AC system by reducing the total envelope heat transfer rate incorporated into a building through the walls. However, the selection of PCM and its configuration of integration with the building materials are subjected to the climate environment. This study conducted examination of the thermal performance of some PCMs that are integrated with lightweight concrete through numerical simulation using EnergyPlus software. The integration of lightweight concrete with a PCM titled RT 35 manufactured by Rubitherm Technologies GmbH company yield the highest envelope heat gain transfer rate reduction. Meanwhile, the configuration that placed the PCM in the middle layer of the building material performs better than the configurations that placed the PCM on the outer and the inner surface of the wall. This is due to the PCM being imposed to a smaller temperature difference with its surroundings. Analysis of the thermal properties of the 20 mm thick PCM RT 35 that is placed on the middle layer of the walls also yields thermal resistance value of the wall which is 0.141 m2-K/W.
