Pandemic Operation, Carbon Reduction, and YOU! How these new design strategies impact the commissioning process

Ari Tinkoff, PE, BR+A Consulting Engineers

Building commissioning has become increasingly prevalent in today’s healthcare/laboratory
marketplace due to the complexity of the Building Systems, Increase in LEED practices, and the AIA
Guidelines for Design and Construction of Healthcare Facilities. This session will discuss the variety of Pandemic HVAC designs that leading healthcare institutions are incorporating and how this will impact future commissioning efforts. Since there are no standards/guidelines – everyone is taking a different approach.

The quality of design, construction, start-up, and operation of healthcare facilities varies from region
to region. We’ll show case studies of various projects from 15,000sf to nearly 2 million sf. We will discuss strategies of new greenfield projects vs renovations vs projects that incorporated Pandemic modes during construction.

Additionally, we discuss several HVAC design strategies that are being applied to help achieve the
2050 Net Zero Carbon goal to these high energy consuming buildings. Overview of how these design concepts will impact future technologies, space allocation, and commissioning efforts.

Understanding Balancing and Fundamental Steps to Balance and Optimize Hydronic Systems

Soham Neupane, IMI Hydronic Engineering

The goal of every HVAC installation is to provide the desired indoor climate at the lowest possible energy cost.
Today’s advanced control technology means that, in theory, achieving this goal is possible. In practice, however, even the most sophisticated controllers don’t always perform as promised.

Condensing boiler and chiller efficiencies are directly influenced by the return water temperature with a potential efficiency loss of up to 10-15%, which can be directly related to balancing. Proper balancing with pump optimization can reduce energy costs by 30-40%. The use of Dp controllers to improve controllability will also be discussed. A hydronic system can only perform as specified if the three key conditions for hydronic control are fulfilled. These key conditions are:

1. The design flow must be available at all terminals.
2. The Dp across control valves must not vary too much.
3. Primary Flow should be ≥ Secondary Flow.

The best way to attain these three conditions is to perform balancing. Balancing can help troubleshoot issues ranging from incorrectly implemented balancing calculations to assembly errors such as incorrectly installed check valves, and blocked filters. It allows you to immediately reveal the effects of any disturbances, identify the cause and take corrective measures to achieve optimal system performance. This presentation is a summary of IMI TAs’ expertise in the three key hydronic conditions and talks about issues like low delta T, unstable controls, the cause and the solutions to those problems, and the advanced tools available to support system diagnostics and balancing.

Outdoor Airflow Measurement: Challenges and Best-practice Solutions

David Dougan, EBTRON
Outdoor air intake flow measurements are affected by external factors such as wind and stack pressure as well as system effects that include fan speed changes and control damper issues. In addition, most rooftop air handling units have intake configurations that limit accurate field and/or permanently mounted airflow measurement. Not all technologies (handheld and permanent) are well suited for outdoor airflow measurement and all technologies have limitations. The presentation discusses these issues and presents a “best practice” approach to measurement, calibration, and verification of outdoor air intake flow rates.

Demand Control Ventilation Applications

Paul Fuson, Siemens

Dynamic control of ventilation (DCV) is now recognized as the leading means to ensure occupant safety, health and comfort while minimizing the energy operating cost. Whether we are talking about an office building trying to achieve WELL Building certification or a chemical laboratory trying to control ventilation rates to reduce hazardous exposure risk, the basic concepts are the same. In all cases, TAB and Commissioning professionals play a key role in successful implementation of these systems. This presentation will cover:

  • the spectrum of airborne contaminants and hazards that drive requirements for ventilation, measurement, and control
  • how DCV impacts selection and sizing of airflow control devices
  • comparison of two technological approaches to contaminant measurement: discrete vs centralized monitoring
  • new commissioning activities needed for DCV systems

Design and Commissioning: Evaluating the Interface with TAB on Projects

Justin Tabor, CxA, Hanson Professional Services
Bradley W. Perrott, PE, Leed AP, EMP, Hanson Professional Services

This session is meant to discuss how TAB is an integral part of a successful project for the
design engineer and the commissioning provider. The importance of TAB and what TAB
technicians can look for within the drawings and specifications for different HVAC systems will
be discussed. The review of the TAB report by the design engineer and commissioning
provider and the key information that both are looking for in the preliminary TAB reports will also
be discussed. Finally, the interaction of the TAB technician and the commissioning provider will
be discussed and cover the process and required measurements that are needed to start the
functional performance testing process.

Creating a People Strategy That Elevates Your Business

Traci Scherck, Elevated Talent Consulting

People make your organization run, delight your customers and produce the outcomes you expect. There is a secret to ensuring that your people stick around, feel appreciated and perform at their best. It is a People Strategy. Finding, hiring, retaining and growing your people into the technicians, leaders and future owners is critical to your success. This presentation will walk you through the different areas of a people strategy, provide you with tools to implement your own tricks to increase your employee retention, and actually have the opportunity to have dinner with your family, as long as you delegate. In this session, you will start to create the plan that you can implement into your day to day business with resources that make it easy.
