Case Study

215 East 68th Street

Electric heat recovery chiller implementation at Upper East Side high-rise

This case study was chosen as part of the Empire Building Challenge competition. Click here to learn more about the Empire Building Challenge competition.

215 East 68th Street is an approximately 1M+ square foot multifamily building in the Upper East Side of Manhattan. Built in 1962 and spanning 32 floors, the building supports tenant heating, cooling, and domestic hot water needs through natural gas boilers and absorption chillers. As a result, the building burns fossil fuels for the entire year, putting the building in Local Law 97 penalty range starting in 2030. Rudin Management plans to retrofit the outdated system with new electric heat recovery chillers to offset natural gas usage and align with New York City’s electrification efforts. The new system eliminates the need for fossil fuel boilers to create cooling and domestic hot water in the summer. The building also intends to install “geo-ready” thermal taps to prepare for a potential future ground loop under the existing parking lot and heat recovery from the 24/7 building exhaust system. The project largely decarbonizes building operations and aligns the building with company-wide sustainability goals.

Lessons Learned

Heat pump technology is rapidly developing, creating cost-effective opportunities to decarbonize and electrify buildings without sacrificing operating costs.

Emissions Reductions

 The proposed retrofit avoids penalties associated with Local Law 97 entirely, while also significantly reducing building energy use intensity.

A baseline assessment is key to understanding current systems and performance, then identifying conditions, requirements or events that will trigger a decarbonization effort. The assessment looks across technical systems, asset strategy and sectoral factors.

Building System Conditions
  • Equipment nearing end-of-life
  • Efficiency improvements
Asset Conditions
  • Capital event cycles
  • Carbon emissions limits
Market Conditions
  • Technology improves
  • Policy changes
  • Infrastructure transitions
  • Fuels phase out

The last major cooling plant upgrade at 215 East 68th Street was in 2001 when three, low pressure steam absorption chillers were installed. Since then, NYC introduced new carbon emission limits as part of LL97. The new laws push for the electrification of buildings to mitigate significant financial penalties associated with burning fossil fuels. In the case of 215 East 68th Street, building ownership is facing annual penalties exceeding $250,000 per year starting in 2030. As a result, Rudin sees an opportunity to replace the fossil-fuel cooling plant with an electric plant that generates domestic hot water and recovers building waste heat. The new system eliminates the 2030 penalty entirely and significantly reduces the building energy use intensity (EUI).

Effective engineering integrates measures for reducing energy load, recovering wasted heat, and moving towards partial or full electrification. This increases operational efficiencies, optimizes energy peaks, and avoids oversized heating systems, thus alleviating space constraints and minimizing the cost of retrofits to decarbonize the building over time.

The central cooling plant at 215 East 68th Street is nearing the end of its useful life, prompting Rudin Management to consider the best plan for the buildings plant. The cheapest and simplest approach would be to replace existing low pressure steam absorbers in kind. Weighing the LL97 penalties starting in 2030, the building saw an opportunity to implement a new and electric heat recovery system to eliminate fines and decarbonize the building’s operations. While the electric heat recovery chillers carry a larger upfront cost, the cost of ownership over 30 years is lower than that of a fossil fuel system with a lower upfront cost but significant annual emissions penalties.

Charrette Overview

A charrette is a focused, collaborative convening of diverse stakeholders. In planning a building decarbonization project, charrettes are a powerful tool for establishing a holistic understanding of a building’s existing conditions and needs, aligning stakeholders, developing creative solutions, and accelerating the retrofit design process.

Context

While charrettes can be used within multiple contexts, this resource has been developed to support the review of a preliminary retrofit plan. The preliminary retrofit plan scope is developed based on existing building conditions, high-level energy data and calculations, as well as the team’s expertise and prior project experience. Having a charrette at this point in the process allows for early feedback about the retrofit scope and alignment with project goals. It provides an opportunity for collaborative problem-solving and the development of creative solutions, as multi-disciplinary stakeholders are brought together to iterate on the retrofit. More detailed energy and financial analysis will occur after the charrette and may drive scope change as the team uses results to optimize the retrofit.

Templates Overview

The following templates have been developed to reduce the effort required to include a charrette in retrofit planning and guide project teams through the charrette process. The format of the templates is intentionally basic so your organization(s)’ presentation format and logos can easily be added.

The templates are intended to be used by the design team to gather feedback and develop consensus from project stakeholders on the following topics:

  • Project goals
  • Retrofit triggers
  • Proposed retrofit plan

Three templates are available for download and are designed to work together. These include:

Pre-Read Template: Use this template to develop a project-specific pre-read document that can help inform the charrette discussion. This template offers a preset agenda for the charrette and provides space to clearly define project goals, trigger events, and a high-level summary of the retrofit plan. To maximize benefit from the charrette it is important that attendees arrive with a solid understanding of the information provided in the pre-read. Therefore, it is recommended the document remain as concise as possible and is sent to attendees with sufficient time for them to review.

Download the Pre-Read Template

Charrette Presentation Template: This easily customizable slide deck template provides a framework and content to guide project teams through the charrette. The intended outcomes from the charrette are level setting stakeholders on the project’s status and plans, collecting feedback, and ideation.

Download the Presentation Template

Post-Charrette Report Template: Use this template to capture outputs from the charrette and distribute to project stakeholders. The report is intended to support the team in coming to consensus on goals, retrofit triggers, and the preliminary retrofit plan. Once finalized, it can be used as a basis for moving into the detailed analysis phase.

This playbook provides commercial office tenants with curated guidance and resources to help prioritize energy efficiency and emissions reduction strategies across various phases of the leasing cycle. Tenants should reference and revisit the information attributed to each step as office spaces within their portfolio move through various stages of the leasing cycle.

This resource is part of a series of actionable resources developed for the Decarbonizing New York City Offices (opens in new window) project, an initiative dedicated to reducing carbon emissions in leased commercial spaces by facilitating meaningful collaboration between building owners, tenants, brokers, lawyers, designers and others involved in leasing and office utilization decisions.
