• New York’s first all-electric tower

  Here’s the thing:

  Nationwide, the biggest single source of emissions is transportation, dominated by low-occupancy cars and trucks. But in New York, most people use mass transit instead of driving. That means buildings “are by far the largest source” of climate pollution in the city, said Christopher Halfnight, senior director of research and policy at the Urban Green Council, a nonprofit focused on energy efficiency in buildings. Gas- and oil-burning furnaces and water heaters are together responsible for 40% of NYC emissions, according to Halfnight.

  In response to this, New York City has been passing laws that restrict greenhouse gases and that by and large incentivize electrification. One of these is Local Law 97, which will generally require buildings over 25,000 sf to reduce their GHG emissions by 40% (relative to 2005) by 2030.

  Already the market is responding. Alloy Development has just completed the city’s first all-electric tower at 505 State Street in Brooklyn. Tenants began moving in on April 5.

  When team members asked what the complex would look like absent gas, the answers were fairly straightforward. “Instead of a gas boiler, an electric boiler; instead of a gas cooktop, it was an induction cooktop. And literally that was it,” said Pires, noting that they had to revise the design of the electrical room to allow for higher amperage, since more incoming electricity would be needed for a larger electrical load.

  Some, or perhaps many, in the industry are fighting these new laws. In 2022, a co-op in Queens apparently went to the New York Supreme Court. But directionally, this certainly looks to be where we are headed. So you can either fight it, or you can try and get ahead of it, as Alloy has done here.

• Density is good

  When it comes to greenhouse gas emissions, we know this:

  Households in denser neighborhoods close to city centers tend to be responsible for fewer planet-warming greenhouse gases, on average, than households in the rest of the country. Residents in these areas typically drive less because jobs and stores are nearby and they can more easily walk, bike or take public transit. And they’re more likely to live in smaller homes or apartments that require less energy to heat and cool.

  We also know this:

  Consider housing. For decades in the United States, the majority of new homes have been built in the suburbs and, increasingly, exurbs, where climate footprints are larger. As a result, for many people today, it is often easier and cheaper to find a home in a high-emissions community than a lower-emissions one.

  An important caveat to these points is that if you use consumption-based carbon accounting — that is, you consider all of the goods and services that people tend to consume — then other things like income also play a major factor. Wealthy households, for example, tend to fly more frequently, and that is bad for emissions.

  But even with this more accurate accounting, the two biggest contributors to a household’s carbon footprint still tend to be housing and driving. And that’s why when you look at emission maps, like these over here, the urban core still usually performs the best. Density, it turns out, is hard to beat.
