LEED CERTIFICATION

Rockefeller Group has achieved LEED certification (Leadership in Energy and Environmental Design) for many of its development projects across the country . We also achieved LEED certification for the office towers at 1221 and 1271 Avenue of the Americas in Manhattan . The LEED certification is formal recognition of a building’s compliance with a rigorous suite of standards for environmentally sustainable construction and operation . The LEED program, begun in 1998 and managed by the nonprofit U .S . Green Building Council, is guided by a broad consensus of architects, engineers, developers, government agencies, builders, and product manufacturers . In addition, the company encourages its development professionals to pursue LEED accreditation .

ENERGY/GHG EMISSIONS

At Rockefeller Group, we understand the impact energy consumption has on a building’s environmental footprint, and we work diligently to reduce overall portfolio energy use . In recent years, we have joined the NYC Mayor’s Carbon Challenge which works toward reducing our emissions by 30% by 2030 for our Core Holdings portfolio . We are also looking to leverage new technologies as we aim to further reduce emissions and are continually evaluating more complex and innovative projects to support our energy reduction efforts .

Energy-Saving Measures Energy conservation measures are routinely undertaken to reduce our portfolio’s energy consumption . Rockefeller Group’s approach to energy efficiency includes, among other things, the installation of high-efficiency equipment and appliances and the use of wall and roof insulation . In 2020, we completed a facade replacement at 1271 Avenue of the Americas which involved replacing the entire skin of the building to improve the solar performance and thermal insulation, significantly enhancing energy efficiency .

To minimize the energy needs of its Core Holdings portfolio, Rockefeller Group strongly encourages the purchase of energy-saving electrical equipment and appliances through the installation of ENERGY STAR models at equipment end of life . Additional Rockefeller Group energy-saving tactics include lighting retrofits and motion sensors, the installation of white/reflective roofs, improvements to HVAC systems and chillers, and the replacement of outdated cooling tower components .

Our Core Holdings portfolio incorporates various systems to monitor and control equipment such as ventilation, air conditioning, heating, lighting, alarms, and communications, ensuring that our systems are operating optimally and efficiently .

SPOTLIGHT: DEMAND RESPONSE PROGRAM

Rockefeller Group is a longstanding participant in a voluntary demand response program, sponsored by the New York State Independent System Operation (ISO) and Con Edison . Demand response seeks to change the power consumption of an electric utility user to better match the demand for power with the supply . When asked by Con Edison to reduce the peak load, we reduce our peak load by reducing lobby lighting, shutting off down escalators, and taking other steps with minimal effect on tenants . If an energy emergency is declared, Rockefeller Group, with tenants’ cooperation, will take additional conservation steps .

WATER

Rockefeller Group is committed to optimizing water efficiency in our Core Holdings portfolio, where all new fixtures must meet or exceed the Uniform Plumbing Code and the International Plumbing Code standards . Many of our other properties incorporate water saving initiatives including low-flow fixtures on toilets/urinals, installed aerators on bathroom and kitchen sinks and leak detection software for indoor water use reduction . Where landscaping is present, many of these properties strive to plant native and drought-tolerant landscaping and utilize smart irrigation .

WASTE

Rockefeller Group believes that comprehensive disposal and recycling plans are essential to fulfilling our environmental commitments, and we continually educate building staff and tenants of our Core Holdings properties on its importance and give tips on how to improve recycling rates . Today, many Rockefeller Group properties have implemented recycling programs and include recycling infrastructure for tenants . We plan to continue increasing the number of properties with a recycling program . In addition to standard recycling, many properties recycle e-waste and construction waste .

Construction & Demolition Waste Management Planning

As part of our building Standards, Specifications and Guidelines, Core Holdings tenants are required to develop and implement a plan to establish diversion goals for at least five specific materials that are anticipated to make up the majority of the waste stream . The plan must establish which materials will be separated and describe a diversion strategy for each . In alignment with our corporate goal, we require that construction and demolition material for three of the primary material streams be diverted from the landfill .

SPOTLIGHT: OFFICE WASTE RECYCLING

In the early 1990s, Rockefeller Group gave its full cooperation and support when New York City’s municipal government first launched an effort to get office building managers, tenant companies, and individual office workers to change their daily work routines so that wastepaper, plastic bottles, and metal cans could be recovered and recycled . Office waste recycling has since become a daily routine at Rockefeller Group-managed buildings and throughout the city with an ongoing campaign to raise tenant awareness; this is crucial to the company’s pursuit of LEED certification . We participate in single-stream office waste recycling . A 2018 recycling analysis for 1271 Avenue of the Americas concluded that the building generated 12 .79 tons of recycling and 52 .21 tons of trash, leading to a 20% recycling yield . This is equivalent to saving 89,530 gallons of water, 1,010 gallons of oil, and 217 trees .

MONITORING AND REPORTING DATA

Data collection and analysis is integral to our Environmental Management System . By measuring and consistently reporting key performance indicators (KPIs) such as energy, emissions, water, and waste, companies are able to conceptualize their overall consumption for these KPIs . Each quarter, we collect environmental data from our Core Holding portfolio using CodeGreen Solutions’ sustainability data management tool, ProAct . Rockefeller Group also utilizes automatic meter readings (AMRs) to collect consumption, diagnostic, and status data from water meters or energy metering devices (gas, electric) . This information is then transferred to a central database for evaluation . The analysis of this information better controls the use and production of electrical energy, gas usage and water consumption . Performance results are then reported back to top executives for review and revision of strategies .
