As the largest city in North America, New York City represents the opportunity and staggering risk of a metropolitan area of 9 million people running on 20th century infrastructure.
From the advent of technologies such as elevators and subways to policies such as PlaNYC and Local Law 97, New York has long been a beacon for urban innovation. With more than 500 million square feet of commercial office space in NYC (all reliant on fossil fuels or Con Edison’s steam system), how can the real estate and construction industry decarbonize at scale, implement solutions that perform over the next 20-plus years and recapitalize our architectural fabric?
The path to revitalize our infrastructure as an engine of future economic growth must begin with a series of "lighthouse projects" that prove viability. The energy industry, real estate sector and city government can’t swallow the elephant whole.
Hudson Square Properties, a joint venture of Trinity Church Wall Street, Norges Bank Investment Management and Hines (with direction from Nordic system integrator urbs) have brought to life one replicable example of a building that brings together public and private efforts to implement decarbonization strategies and multi-generational thinking that have been proven in other markets.
At 555 Greenwich Street in lower Manhattan, a 270,000-square-foot, 16-story, LEED-Platinum office tower connected to a former warehouse building via a horizontal overbuild is the first speculative office development in New York City to break ground in the wake of the COVID-19 pandemic. It also serves as a tangible example of the first office building to use a thermally activated slab with geothermal wells — a design that reduces carbon emissions by 50 percent while eliminating any fossil fuels used for heating and cooling. With all-electric heat pumps, the building surpasses the targets set by the NYC’s Climate Mobilization Act, one of the most ambitious climate programs put forth by any city in the world.
Lighthouse projects such as the one at Hudson Square operate without fossil fuels, are energy efficient and exceed LEED standards. They are the first step to scale.
Capital providers, including public entities such as the NY Green Bank and private entities such as Norges Bank (which manages about $27 billion in direct real estate investments on behalf of the Norwegian Government Pension Fund) are joining the ranks of bankers funding commercial and multi-family residential decarbonization projects, most notably the Empire State Building and the Arverne East project in Queens.
The architecture and design community has been pushing the idea that high-performance buildings support physical health and mental wellness for years. Engineering firms are building practices in low-voltage, direct outdoor air systems (DOAS) that provide better ventilation with 100 percent outside air, and decouple sensible and latent cooling functions of air handling systems. Other advanced systems, such as geothermal and chilled beam systems that reduce carbon, are seeing renewed levels of interest and investment. Architects and construction management firms are growing their expertise in planning, design and engineering of net-zero buildings. And the development community is learning to speak ESG, driven by tenant demand.
Given statewide targets for 85 percent reduction in GHG emissions by 2050 and a 100 percent renewable grid by 2040 in New York state, the engineering, design and finance community working in real estate is starting the hard work of electrifying, reducing peak demand and emissions and meeting the resilience mandates demanded by our climate reality today.

We are in the early innings of a challenging new era where remote work, inflationary pressures and a housing crisis are just a few headwinds faced by the proptech industry. While some net-zero projects can be unilaterally championed by a motivated developer (Veridian at County Farm), others are the result of partnerships between policymakers and communities to advance energy resilience and health and wellness (Arverne East).
According to the New Buildings Institute, the number of verified zero energy buildings in the U.S. and Canada more than doubled between 2018 and 2020, a sign that designers are gaining expertise for delivering on zero energy targets set by building owners. Based on proven pathways in Europe, a new American appetite is emerging for building electrification, district energy systems that can provide for heating and cooling and community microgrids that can provide both energy security, reliability and reduced emissions.
In order for lighthouse projects such as Hudson Square to drive broader, community-scale change, rather than existing as an isolated example of what could happen if all the Swiss cheese holes line up exactly right, existing buildings must be mandated to audit and execute on energy efficiency opportunities; the gateway drug of the energy transition. Federal and local government must continue to make investments in research and development and provide thoughtful tax policies and incentives. With these ingredients, sophisticated capital can engage and will lead by example. Competitors across the real estate and construction value chain will adapt, follow or get left behind.
As momentum builds and federal infrastructure dollars begin to be deployed, we need more replicable models for how we decarbonize not just buildings but entire communities in NYC. This scale of change requires large scale and financially attractive investments in anchor institutions (especially in public housing and critical infrastructure such as mass transit); a robust supply chain for innovation; joint procurement partnerships; workforce development and an inclusive approach to environmental justice communities; and dissemination of results.
Mortgage lenders and packagers should abandon their practice of requiring "triple net leases," which assign total building energy costs to tenants according to their share of net rentable space in the building, as a prerequisite for funding or securitizing mortgage loans. The result of this policy, designed to reduce the risk of mortgage defaults from energy price spikes, are that: building owners have no financial incentive to enhance the energy efficiency of their buildings; and individual tenants have no direct financial incentive to reduce energy use in the space they occupy.
Perhaps our most significant hurdle is cultural: The real estate construction, development and management industry habitually squeezes nearly all the risk out of execution, which represents a significant barrier to change for deployments of solutions that deliver efficiency gains but are not yet industry standards.
Accelerated by COVID and remote work, the real estate industry is shifting from a commodity business to a service business. This is not the only monumental shift it must manage.
The International Renewable Energy Agency has estimated that $7.5 trillion worth of global real estate could be "stranded"; these are assets that will experience major write-downs in value given climate risks and the economic transition, making real estate one of the hardest-hit sectors. While buildings that have embarked on a path to net zero can benefit from 6-11 percent higher rental premiums, buildings with no pathway are likely to depreciate significantly over the next two decades and could face obsolescence driven by occupant demands, legislative regulations and penalties, and investor expectations.
The mindset of risk is changing, and with more than 142 million homes in the U.S. and 6 million commercial buildings, the scope of the challenge and opportunity is massive. The road may be bumpy. Investing in more lighthouse projects and scaling success makes the path forward clear.
