Proposed Session Description
The conventional strategy for achieving IAQ goals relies on prescriptive amounts of outside air to dilute and thus reduce concentrations of contaminants such as carbon dioxide, formaldehyde, and total volatile organic compounds. As a result, designers must size HVAC equipment including heat pumps to be capable of tempering large volumes of ventilation air during both summer and winter peak weather conditions – a significant factor when calculating energy usage intensity (EUI) that negatively effects Net Zero design goals. This session will present a system level approach to achieve net zero ventilation and enhanced IAQ using heat pumps, energy recovery, sorbent air cleaning, and a performance-based ventilation design approach.
Why is this session important?
One of the largest barriers to building electrification is the potential increase in electrical load on specific buildings and the electric grid overall during peak heating conditions on the coldest days of the year. Traditionally ventilated commercial buildings must bring in 1-2 air changes per hour of outdoor air even during periods of extreme low outdoor temperature conditions, driving the amount of electric or heat-pump heating required to maintain proper indoor temperatures. Using a performance-based approach to ventilation and using sorbent air-cleaning technologies, building designers and operators can maintain IAQ at reduced ventilation rates to reduce the heating load on buildings during peak winter condition thus allowing wider adoption of electric sources of heating and energy recovery in new and existing buildings while also reducing load on the electric grid.
Comments
Maybe - I agree with Amalia's
Maybe - I agree with Amalia's concerns. I do think it is helpful to discuss the engineering challenges - while we have components, the system design remains quite complicated.I might be able to bring in someone from one of the EBC projects - but (disclosure of interest) I have a relationship with a participant in one of those projects.
Maybe - I share the same
Maybe - I share the same concerns as Amalia. Given the speaker's interests, this sounds like a sales pitch. The similiar session last year included two other speakers to balance out this concern and focus the talk on real-world applications of the technology and the results.
Diversity and Inclusiveness
This presentation doesn’t address diversity, equity, and inclusion directly but the general topic of electrification and decarbonization benefits all people and especially front-line communities who are most impacted by the climate crisis. We can include general statements about the impact of climate change, including from commercial buildings, on frontline communities in the presentation.
Learning Objectives
Through active engagement, attendees will identify innovative design strategies that contribute directly towards reducing peak HVAC building loads and EUI associated with HVAC systems.
Understand the implications of performance-based indoor air quality and energy recovery design on compliance with ASHRAE Standard 62.1, ASHRAE Standard 90.1, LEED Rating System including LEED Zero, WELL Rating System, and the International Building Codes.
Compare and contrast the economics associated with conventional ventilation design strategies with performance based indoor air quality design, and the resultant effect on electrification building design.
Putting it all together, deep-dive into NYC based demonstration project in a large historical office building located in mid-town Manhattan.

Anything else you'd like to tell us about your session proposal?
This presentation will align nicely with NYSERDA’s Resource Efficient Electrification framework, an approach to electrify tall buildings that NYSERDA has developed based on lessons learned from the Empire Building Challenge, and with NYSERDA’s Energy Efficient IAQ Studies, which highlighted the significant “energy penalty” associated with simply increasing outside air to reduce airborne infectious aerosol exposure risk and pointed to alternative strategies that could more efficiently achieve the same risk reduction goals. The presentation will speak to and reinforce the findings from both NYSERDA initiatives.

Committee Decision

Yes for this talk.
Maybe++ for this talk.This talk will help inform design professionals on ASHRAE 62.1 IAQ Procedure (IAQP), which can help reduce heating & cooling (kWh and kW) costs, load sizing, and equipment costs while maintaining IAQ ventilation goals. One main concern is that the talk is being presented by a manufacturer of sorbent air-cleaning technology. Although these are at the heart of the ventilation systems that incorporate IAQP design principles, we need to be careful that we are not providing support to a product. We should guide the talk to should focus on design principles, details and approach to incorporating ASHRAE 62.1 IAQP, and control and operating procedures. Case examples should be provided for comparing IAQP vs the more traditional ventilation rate procedure (VRP). We should have a second speaker that is not from enverid. The second concern is that this speaker had a similar discussion last year on IAQP. How different will this talk be from last year's? See link:https://nesea.org/session/performance-based-ventilation-design-healthy-… could be an exciting talk for design professionals, especially engineers. But we need to make sure we do not repeat ourselves.
