O casal norte-americano Julie e Scott Brusaw tem um sonho ambicioso: trocar todo o asfalto do mundo por placas solares, o que reduziria drasticamente as emissões de gases de efeito estufa e geraria energia limpa e renovável. A boa notícia é que o plano visionário está mais perto de se tornar realidade.
Batizado de Solar Roadways*, o projeto dos dois recebeu US$ 2,2 milhões via financiamento coletivo – aliás, mais que o dobro do valor que pediram inicialmente na plataforma de crowdfunding Indiegogo. O dinheiro veio de mais de 48 mil pessoas, de 42 países. Um sucesso! Especialmente, porque o vídeo de divulgação viralizou na web, com mais de 19 milhões de visualizações

Como colocar o projeto em prática? Para responder a essa pergunta, vou contar a história do começo. Quando tiveram a ideia de instalar painéis fotovoltaicos no chão, o casal passou a pesquisar uma forma de fazer as placas aguentarem muito peso. “Queríamos painéis solares em que você pudesse dirigir, estacionar e andar em cima”, conta Scott, que é engenheiro elétrico, no site da iniciativa. A pesquisa durou oito anos, mas foi bem sucedida!
Com financiamentos da Administração Federal de Rodovias dos EUA, o casal desenvolveu painéis que podem aguentar mais de 113 toneladas. Feitos de vidro (10% do material é reciclado!), cada módulo possui pequenos hexágonos que contém células solares.

Agora, o dinheiro arrecadado com o crowdfunding será usado para viabilizar a tecnologia no mundo todo e contratar profissionais. “Esses painéis podem ser instalados em rodovias, estacionamentos, calçadas, ciclovias e playgrounds… Literalmente, em qualquer superfície abaixo do sol”, conta o casal em seu site.
A ideia é que a eletricidade gerada pelas placas abasteça casas e empresas. De acordo com os cálculos do casal, um sistema nacional de painéis pode produzir mais energia limpa do que os Estados Unidos usa como um todo.

 Além disso, o Solar Roadways também tenta convencer com outros benefícios, como:
- fazer crescer o mercado de carros elétricos, graças aos novos postos de abastecimento de energia;
- acabar com os postes de energia das ruas, já que os fios de transmissão de eletricidade seriam subterrâneos;
- descongelar neve que fica acumulada nas vias, e
- sinalizar com iluminação LED pessoas e animais atravessando a pista à noite.

Reuso de edificação histórica adaptada ao jeito de viver contemporâneo, Berlin / Alemanha


factory-berlin-jba1

This project demonstrates the finest qualities of adaptive reuse…of a former brewery. Built in Berlin over the late 1800s and early 1900s, the building’s five distinct parts were restored and unified by a two-story addition. Julian Breinersdorfer Architekten removed the plaster coating on the original brick facade. With little historical data, recreation of the pre-World War I elements was tricky but successful.
Serving as a start-up campus, the ground floor of the now 10,000 sq.m. facility is occupied by a restaurant and co-working spaces. Courtyards, gardens, and access to event spaces on the lower level complete the ground floor. New glass facades step back from the original thick brick arched openings creating a bright, airy, and covered circulation space. The two-story glass and steel wall respectfully floats on the worn brick floor. By mimicking the scale and pattern of the brick structure, the modern intervention enhances the character of both.

Occupied by Twitter, Soundcloud, and 6Wunderkinder, the Google-sponsored campus added two roof top levels on the existing buildings. The architects’ awareness and acceptance of the original structure created an exquisitely integrated modern expansion. Receding and protruding volumes are clad in ivory and dominated by charcoal grey framed glazing. These elements reduce the expansion’s weight and even add rooftop courtyards.

Internally formerly disconnected spaces and floors are joined through open multi-level open stairwells. By maintaining and restoring the original concrete floors, barrel vaulted ceilings, and structure, the architects have created a voluminous, bright, edgy office campus.

Hidrocerâmica: novo material dá adeus ao ar-condicionado e ventiladores

O Instituto de Arquitetura Avançada da Catalunha (IAAC) abriga um experimento que pode revolucionar os sistemas de ventilação dos seus projetos. Baseados na tecnologia de hidrogéis, os alunos do Instituto desenvolveram a hidrocerâmica, um material inteligente que responde naturalmente às condições climáticas.
Descubra como funciona a seguir.

Materiais inteligentes na indústria da construção.

O sistema funciona a base de hidrogéis, substâncias que crescem cerca de 500x seu próprio tamanho na presença de água. Assim, quando está frio e chovendo, o hidrogel cresce e atua como um isolante térmico.
No calor, a água do material evapora lentamente, refrescando os ambientes de 5 a 6ºC
Inovações em materiais de construção.

O resultado final aparece na hidrocerâmica, que junta o hidrogel a estruturas de cerâmica e tecido, formando uma placa.
Estes materiais adicionais permitem que o hidrogel mude de tamanho sem comprometer a estrutura ou o orçamento do projeto.
Todos os materiais envolvidos tem baixo custo, e estima-se que economizem cerca de 28% em eletricidade, já que as placas de hidrocerâmica dispensam qualquer outro sistema de ventilação adicional, como ventiladores e ar-condicionado.

Estudantes espanhóis aplicam a biocerâmica na indústria na construção.

O material ainda está em fase de testes, mas já é um avanço em direção a novos projetos de arquitetura e construção responsivos, que entendam as dinâmicas de temperatura de um edifício e se adaptem a elas sem utilizar sistemas artificiais.

Project description
Link is an infill house in the historic Pierson Place neighborhood in Phoenix, Arizona. The house is named “Link” as it was the last vacant parcel in the neighborhood, or as we saw it, the missing link. My firm The Ranch Mine, comprised of myself and my wife Claire, was hired by Evan Boxwell of Boxwell Southwest to design a 2000 SF, 3 bedroom, 2 bathroom spec house on this vacant lot.
The house is designed as part of the urban fabric connecting it both to its site and its neighborhood, visually and physically. Sliding glass walls, 24 feet wide, enable the homeowner to open up the entire living space of the house, extending the living area outdoors to either the private backyard, the social front yard, or both. The living and dining area of the house essential can transform into an open air pavilion, ideal for entertaining. The bedrooms, bathrooms, and storage areas of the house are located in the private, main volume of the house.
The house uses large overhangs to shade the large glass doors from April through October, and those doors provide unbelievable cross ventilation to cool the house on the cool desert nights. LED lighting and advanced framing construction also help to keep this house incredibly energy efficient. The house had to pass The City of Phoenix Historic Preservation committee, so the design focused on abstracting the common scale, form and massing of the existing houses in the historic district into a contemporary interpretation.

Matatena Headquarters in Merida, Yucatan, Mexico


architecture modern office Balancing Comfort and Formality: Modern Matatena Offices in Mexico

modern office 1 Balancing Comfort and Formality: Modern Matatena Offices in Mexico

When developing the design plans for Matatena Headquarters (a creative drawing association based in Merida, Yucatan, Mexico), Desnivel Architects aimed at creating an environment that was not office-like, yet not too formal either. In order to extend space, the owner had the idea of using a mix of wood and concrete, in combination with white plastered walls. Going with a double-height working room also helped with the scale of the project. A beautiful chaka tree was employed as the focal point of the scheme. This tree brings life into the space, thus overcoming the sober feel inspired by concrete.

The resulting program (occupying a total surface of 206 square meters) consists of four working zones, service area, reception, boardroom, kitchen and two bathrooms. Work here is generated in a relaxed but professional environment and a cafe was a perfect logical addition to exemplify the vision of the company. This place pays tribute to relaxation, but also functions as a hanging out spot for brainstorming ideas. What do you think are the benefits and drawbacks of working in an office like this ?

Bower Architecture designed the Hover House, located in Mt. Martha, Australia.

Nesta casa de praia os arquitetos brincaram com as texturas dos diferentes materiais utilizados no projeto. Com sucesso integraram as premissas de projeto: tranquilidade, sustentabilidade e privacidade, organizando a casa em função do jardim interno, mais privado, que fornece iluminação natural aos ambientes. O monobloco que vai da divisa leste a oeste facilita o recolhimento de água da chuva e incorpora sistemas passivos de sustentabilidade. Com o uso de tijolos de concreto para a pior orientação solar(Sul), aberturas generosas para o Norte que também proporcionam uma boa ventilação natural, criou-se uma massa térmica isolante do frio e um jardim interno que capta todo aquecimento solar.

Project Description:
Hover house is a residence in beachside Mt. Martha (Victoria, Australia) re-imagining the single dwelling courtyard on a rear battle-axe block. The project brief was for a tranquil, sustainable and private home filled with natural light, warmth and texture. As privacy and outlook were limited the concept sought to create a captivating internal focus in the form of a central courtyard, providing a strong link between key spaces. In order to maximise natural light and privacy a simple sectional gable shape was extruded through the east-west axis of the house, resulting in a form that efficiently collects rainwater, incorporates sustainable passive systems and emphasises views to distant gum tree canopies.
Hover House provides the clients and their friends and family with a warm and functional home all year round, adaptable to varying internal and external circumstances. Lovingly detailed concealed sliding doors and timber screens allow for the flexibility of each bedroom wing to be open or closed independently from the main living space, aiding energy efficiency and privacy and varying the character of the house with different configurations. Bedrooms and kitchen areas also capture discrete connections to exterior gardens around the site periphery, complementing the courtyard focus of the living and entry areas.
Internal concrete blockwork, timber veneer and a polished concrete floor provide cost effective texture and warmth throughout the internal living spaces. The reverse veneer blockwork, insulated concrete slab and fireplace are also effective as thermal mass and, combined with passive ventilation, result in a low energy house which is cost effective to run.
Hover House is a “replicable prototype for cost effective, high amenity housing” (Nigel Bertram, AIA Victorian Architecture Awards Jury 2014) suitable for other sites where a hostile outlook invites the creation of a meaningful inward focus.
