As part of the EthiopiaStudio2.0 I had the wonderful and unique opportunity to travel into a remote village community 150 km southwest of Addis Ababa, the capital of Ethiopia, Africa. In collaboration with Mesganu Arga and through the help of Keri and Brian DeGuzman, Arizona State University, the Woreda Education-al Bureau, and DeBartolo Architects, the EthiopiaStudio2.0 was given the unique and unbelievable opportunity to design a new school which will address the educational needs of the community and provide an opportunity for the children of Mekana Kebele to complete elementary, junior, and high school and open for themselves all the doors of future potential. The renovation/ addition will increase the number and quality of classrooms, provide space for a library and computer center, and bring hope for a future by changing the cycle of poverty through education.

EthiopiaStudio2.0 developed a master plan, landscape and architec-tural design and construction documents for the immediate construction of these desperately needed facilities to support the growth of education and poten-tial in Mekana Kebele.

As part of the team I was very involved in the facade and building/classroom design. In addition I played the role of an environmental consultant. When preparing the construction document the “ikea” kit-of-part ap-proach was explored as a way of communicating our ideas internationally. I took on the role of preparing the axonametric diagrams explaining the panel/facade design.

Intricacy is marked by components which are elaborately complex. In architecture those components are key to a building which has a rich ar-ray of scales and rewards the senses such as sight and sound, for example. Through its orchestration of light and shade it elevates the spirit and mind and our lives become enriched.

In the case of 506 South Mill the challenge of intricacy caused me to address issues such as light, shade and sound. As one enters the site leaving the sounds of Mill Avenue behind, one enters the courtyard, the cen-tral space of 506 South Mill. Once in the courtyard, a semi public space one moves up into the living spaces after being showered with light. Light as a signifier of transition/ threshold is a key component of the architectural story of the building.

As a result one enters the light wall when moving into the most pri-vate spaces located on the second floor. Once again one gets showered with light and catches glimpses of the immediate context through the slivers and openings in the screen when moving up. Ultimately one reaches the roof top patio where the sounds of Mill avenue are faded and a view into the distance opens up.

Buildings have traditionally been associated with stability and permanence, this association has been questioned by archi-tects such as Erich Mendelsohn and Le Corbusier. Learning from their investigations, strategies such as inclined planes, horizontal emphasis and acceleration of facade rhythm have been ex-

plored, in order to showcase dance through architecture.

In addition a dynamic facade, an art installation moving with wind, has been incorporated. As a result the

“wind veil” reflects the movement of the site.

An addition to the existing “pro-line” fitness center was to be designed. The client requested additional workout space to house the new “Miha-circle” work out equipment. In addition he requested an expansion of the wellness space.As a result “the fitness-box” was designed as the primary shape, wrapped by the wellness space, the so- called “Ruheraum.” It was my responsibility to develop the de-sign and communicate the design idea to the client.

Green roofs are a popular sustain-able strategy among architects and landscape architects. They are being incorporated to help with rainwater runoff mitigation and strategy known to reduce the Urban Heat Island (UHI) Effect.

However, in a hot arid climate they exacerbate rather than mitigate the UHI. This is due to the high thermal storage capac-ity of soil required to sustain the green roof. UHI is a night time, rather than a daytime phenomenon, in such a climate.

In order to make green roofs a sustainable strategy in a hot arid climate, the thermal perfor-mance of the hydro-roof was eval-uated as a possible alternative.

Overnight studies of three test cells have been conducted during the month of July, 2011, in Tempe, Arizo-na on the fourth floor of the College of Design North building, on the Arizona State University Campus.

The results show both alterna-tives mitigate the UHI and pro-vide additional benefits to the ecosystem and community in a pos-sible urban garden application.

After constructing, the thermal performance of each test cell was evaluated using an Agilent data logger fitted with thermocouples. The temperature was recorded in 1 minute intervals and graphs have been produced.Additionally, infrared images were taken by an infrared camera in 15 minute in-tervals.
