The Closest Look Yet at the Relative Energy Efficiency of Big Buildings

The Closest Look Yet at the Relative Energy Efficiency of Big Buildings | Urbanisme | Scoop.it

New York City's largest buildings have as outsized a place in the city's energy use profile as they do in the skyline. Just 2% of New York's properties account for 48% of the city's energy use. 

What's a city to do? The Bloomberg administration is doing what it does best: crunching massive amounts of data. On Wednesday, the mayor released the city's second annual benchmarking report, which analyzes the year-to-year energy and water use of New York's 26,680 largest buildings. 

"It's the first time we've had access to this comparative information," says Melissa Wright, an associate director of the Natural Resources Defense Council’s City Energy Project who has worked in the Bloomberg administration. "For so long it was this hidden information about what the real energy performance was of a set of buildings or individual buildings."

Smart Cities and the Smart Grid

Smart Cities and the Smart Grid | Urbanisme | Scoop.it

Smart Cities and the Smart Grid: There are natural parallels between the Smart Grid and smart cities in terms of concepts and deployments, though cities have much more experience at evolution than the traditional electrical grid. After all, they have been adopting new technologies that disrupt the status quo for centuries. The Romans created aqueducts and fundamentally changed how water could be controlled and distributed in cities. Discoveries in hygiene and disease transmission and control allowed people to healthily live in population densities with minimized odds of large scale epidemics. And then automobiles exerted their influences on cities. In each case, city systems, policies, and people changed to accommodate new technologies, new knowledge and new practices.

 

Now, ambitious goals such as zero net energy buildings will change the relationships that physical structures have within cities, and in turn change the relationships that occupants (full or part-time) have within buildings and within cities.

The World Green Center in Chile Aims To Reshape the Capital’s Cityscape

The World Green Center in Chile Aims To Reshape the Capital’s Cityscape | Urbanisme | Scoop.it

The World Green Center in Chile aims to maximize the amount of public spaces through sustainable design.


The LEED-pending project in Chile has a sprawling green roof designed by Santiago-based cCe Arquitectos. More than 72% of the ground surface is utilized as green space and the completely landscaped roof is covered with shaded terraces and gardens that reduce the heat island effect. Passive design is incorporated within the façade, which reduces solar radiation and minimizes the energy used for air conditioning.

A VRV climate control system is designed to save up to 40% of the total energy compared to traditional office buildings in Santiago. Focusing specifically on the worker activity, the architects made sure each part of the work day is improved through a connection to nature – from a meeting room to an outdoors lunch break.
