Retrofit Now! Reducing Carbon and Complying with LL97

Event Prices: 
Member (AIA, ASHRAE or Urban Green)

*This event is occurring as a live webinar. Registrants will be emailed a link to access the program.

**Seminar will take place on 4 half days Mon/Tues on Nov 9,10 and Nov. 16,17, respectfully. Attendees must join all four sessions in order to receive Continuing Education credits. In order to facilitate instruction, the max class size is 20.

Over the years, New York City has passed a series of laws addressing energy use in existing buildings, culminating in LL97 of 2019. The buildings targeted encompass almost 60% of the city’s overall square footage, so this law represents an extraordinary business opportunity for architects and other designers.

This class will provide a comprehensive overview of the regulatory environment to architects, other designers, and building owners and managers; it will prepare them to make significant contributions to energy and carbon reductions in the existing buildings in which they are involved (1) as part of teams pursuing retrofit projects intended to reduce energy/ carbon, and (2) working on typical incremental renovations which have energy/ carbon reduction potential.

Course content focuses on preparing attendees to maximize the reductions achieved in both types of interventions and to provide a framework for advising building owners and managers that can create long term relationships and drive deeper reductions.

Key topics we will cover include:

  • Regulatory and Existing Building Stock Context
  • Retrofits, Deep Retrofits and Capital Asset Planning
  • Typical Architectural Renovations that can be leveraged
  • Engineering Strategies for Energy Use Reduction
  • Financial and Technical Assistance

What this class will and will not do:

  • This class will introduce architects and other designers to basic carbon reduction engineering strategies to help them to better partner with engineering teams, to anticipate the architectural implications of engineering interventions, and to advise owners about engineering strategies they might pursue. It will not teach them to perform the engineering aspects of energy/ carbon reduction projects, such as audits or specifying specific improvements to steam heating systems or other HVAC equipment.
  • This class will concentrate on some of the most common architectural features found in larger NYC buildings, such as flat roofs, punched windows, window AC’s, and steam heating systems, and the most common renovations/ retrofits undertaken by non-engineering professionals. Given the variety and complexity of New York’s building stock, this class will not address every type of building system or every type of renovation.
  • Finally, this class is conceived as a broad introduction to elucidate major concepts and strategies but will not go into deep technical detail about each item covered.

November 2020 Session dates, 9 am – 1 pm each day:
Monday, Novemeber 9
Tuesday, Novmeber 10
Monday, Novemeber 16
Tuesday, Novmeber 17
(each day will include brief breaks)

The course will repeat in December 2020. As a Cross-Learning Alliance event, this event is discounted to ASHRAE, AIA, and Urban Green Members. Cross-Learning Alliance events are designed to bridge the knowledge gap between the people that own, design, build, manage, operate and commission buildings.
