Feature Presentation:
Humber River Hospital Rehabilitation
One of Ontario's largest regional acute hospitals, serving over 850,000 residents in the northwest Greater Toronto Area, University of Toronto-affiliated Humber River Hospital is the first fully-digital hospital in North America.
Key features of this state-of-the-art healthcare centre include voice recognition for prompt bedside charting, robotic blood testing (with results ready in minutes as opposed to hours), and the ability for patients to order food, use the phone, and control their lighting directly from their bedside terminal. Additionally seventy five percent of supplies are delivered by automation, including robotic delivery of non-narcotics.
The results of the design work can be seen on all levels of the new 14-storey hospital. The building operations command centre, food court, retail shops, and the spectacular outdoor amphitheater are all located on Level 0. Uniquely, the site incorporates a natural slope which allows in more natural light than an average building's lower floor. Levels 1 through 14 offer a variety of services, including a comprehensive range of acute care services and support featuring the best technology available for patient's needs.
Designed and constructed to LEED Silver designation under Infrastructure Ontario's DBFM procurement, this project exceeds the energy efficiency requirements of the Model National Building Code (MNECB) by 49%.
Sustainability was a major component in this project, with mechanical systems that include a condensing dual fuel boiler plant, high efficiency heat recovery chilled water plant, low velocity air handling systems, air and water side energy recovery and low flow plumbing fixtures for reduced water consumption.
HDR's presentation will centre around the use of dynamic glass (or smart glass) in the project. At almost 26,000 sqft it is one of the largest smart glass installations in the world and makes a major contribution to the overall energy efficiency of the building.

January Dinner Meeting Summary

January Dinner Meeting Summary
Active Chilled Beam Systems
The main presenter at January's meeting for the ASHRAE Toronto Chapter was Hugh Crowther. Hugh Crowther is Vice President - Engineering for Swegon North America. Hugh has over 25 years experience in the application, design and commissioning of applied HVAC systems and is an expert on large HVAC system design, high performance buildings and sustainable buildings.
Hugh is a Professional Engineer with a Bachelor of Science in Mechanical Engineering from Queen's University. He is an ASHRAE Member and has twice been on the Board of Directors for ASHRAE. He has held multiple positions within the Society in areas of Technology and Standards. Hugh has also written articles for the ASHRAE Journal, High Performance Buildings, HPAC Engineering and Engineered Systems as well as numerous application guides on a wide range of HVAC topics.
At the meeting Hugh delivered a presentation on the topic of active chilled beam systems and discussed several of the design considerations that must be taken into account when designing an active chilled beam system.
The technology used in chilled beams is relatively new to North America, with installations only gaining popularity approximately 10 years ago. However, the technology has been in use in Europe for over 25 years.
An Active Chilled Beam is a combination air-water system that uses the energy conveyed by two fluid streams (air and water) to achieve the required cooling or heating in a space. The air supplied by the central air handler to the Active Chilled Beams is called primary air. The primary air is supplied to the Active Chilled Beams at a constant volume and at a relatively low static pressure (typically under 0.5" w.c.).
Within the Active Chilled Beam unit, the primary air is discharged from the primary air plenum into a mixing chamber through a series of nozzles. A zone of relative low pressure is created within the mixing chamber, thereby inducing room air through the secondary water coil into the mixing chamber. The induced room air is called secondary air. The secondary air mixes with the primary air, and the mixed supply air is delivered to the room.
In the cooling mode the primary air is normally delivered cool and dry, satisfying a portion of the room's sensible load and its entire latent load. The secondary water coil within the Active Chilled Beam is supplied with chilled water to satisfy the remaining sensible load of the room. The chilled water temperature is always provided above the room design dew point temperature to preclude sweating/condensation on the water coil.
Chilled beams use water to cool the air in a room and typically rely on the convection in a room to draw warm air up to the beam where it is cooled and falls back to the floor to restart the convection cycle. No fans are installed in the chilled beams, which is one of the significant ways that they can reduce energy consumption. Hugh explained as part of his presentation that spaces are rarely at their design occupancy and as a result, a lot of energy is wasted by the use of fans which are continually on in typical air flow systems. By using chilled beams and relying on convection to create cooling, energy consumption is reduced. Energy consumption is also reduced since the technology relies on water to transport heating and cooling which is more efficient and cost effective, as opposed to using air in a typical VAV system. Essentially, a chilled beam acts as an induction unit which has been placed in the ceiling.
An important point which Hugh raised during his presentation was that the airflow pattern is important to consider when designing a chilled beam system. The location of the beam in relation to the air flow must be considered to allow adequate movement throughout the entire room. There are two typical types of air distribution. The first is a mixed system which aims to have all the air in a space mixed to the same temperature. The overhead mixed air systems used the Coanda effect to distribute air. This is the system that most beams rely on. The second option is the Displacement System, where the air is introduced at the floor level. This causes a slower mixing rate and stratifies the space. In this system, only the occupant zone is conditioned. Chilled beams can also have varying types of diffusers depending on the desired type of air distribution. It is important to consider which system is right for your application.
It is also important to note that since chilled beams do not have fans, the air handling systems must supply 100% outdoor air. Since air must continually be blown across the beams in order to create air movement and induction, chilled beam systems are the most practical for use in spaces with high sensible heat loads. Office spaces are a great example of this. With the constant heat from office equipment, solar gain and people, their continual need for cooling is a perfect application for chilled beam systems. Another great utilization because of these requirements is hospitals, which require 6 air changes per hour, meaning lots of continual air flow and a maximized opportunity for induction. Some typical room uses such as hotels may not benefit from the use of chilled beams as much due to their type of occupancy.
Hugh went on to explain that on top of considering the sensible heat load within a space, it is important to consider the latent heat load when designing a chilled beam system. The air being brought into a space needs to be dry enough to allow for cooling to take place, but avoid condensation on the chilled beam. In most cases, the latent head load will typically set the airflow needs for a space. This also means that depending on the capability of dehumidifying the air, the cooling capacity of the beam will be determined by the latent heat load. If the room is becoming too humid, the chilled water temperature can be reset to accommodate the humid air. The negative drawback, of course is that the ability of the beam to reduce the sensible heat load in the space is reduced.
When designing the primary airflow rate for a chilled beam system, the rate must be the larger of:
- The airflow rate to meet the ventilation rate for acceptable indoor air quality
- The airflow rate to provide latent cooling
- The airflow rate required to assist in meeting the sensible cooling load.
Typically, the latent load governs the airflow rate.
Hugh's presentation showed us that there are several applications in which chilled beam systems can be used to create a comfortable environment while reducing energy costs. However, there are several important elements to consider such as the occupancy, air flow patterns and latent and sensible heat loads when considering a chilled beam system for your project.

Viewpoint

Today I'm getting ready to head down to Orlando for the 2016 ASHRAE Winter Conference. By the time you read this, the conference will be over so it's too late for me to encourage any of you to attend- for this year at least! The winter conference also features the AHR expo which is the industry's largest trade show. As a young engineer of ASHRAE who sits on the Board of Governors for our Toronto Chapter, I am very proud of our Board for all their support towards young professionals in our industry.
At the regional and society level, there is a lot of support for any YEA member who wants the opportunity to shadow an ASHRAE officer at the winter and summer conferences. All costs are covered by ASHRAE for a successful candidate through the Leadership U program. Similarly, the YEA LeaDRS program gives YEA members the opportunity to shadow a Regional Chair at the ASHRAE conference.
In addition to the support from the regional and society level, our chapter is actively involved in helping YEA members. We sponsor and send about 8 to 10 students every year to the winter conference. It's an excellent opportunity to network with other professionals from across North America. As a chapter, we are very fortunate to have the resources required to make this happen and is all because of our members. Without a strong membership base, we wouldn't be able to invest in young professionals who will carry our chapter forward in the future.
