Time, energy & form
Physical manifestations of time occur in natural forms of all sizes. Architectural form serves as shelter while providing a built envelope of human life, simultaneously influencing and influenced by energetic activities which occur within the containment. Change is either progressive or cyclic, …

The urban design of distributed energy resources
Distributed energy resources (DERs) are a considerable research focus for cities to reach emissions reduction goals and meet growing energy demand. DERs, consisting of local power plants and distribution infrastructure, range from urban to neighborhood scale. In optimizing neighborhood scale DERs, …

The form of clean energy neighborhoods : how it is guided and how it could be
The subject of "clean energy city" has attained increased attention in recent year. However, almost all studies to date about "clean energy" are either at the building scale or the regional scale and little touches the real estate development scale, or in other words the neighborhood scale. The …
