New Year, New Topics
After a year that seemed like a decade, we have finally
arrived at 2021. As I am writing this in mid-December,
progress on vaccines is looking promising, and there is
hope that as winter turns into spring we will be able to
begin the process of resuming our normal activities.
Buildings that haven't been used or haven't been
used to their full occupancy need some special attention paid to the
HVAC systems. For instance, it's important to perform any deferred
or near-due HVAC maintenance to ensure the system is working
effectively. More details are included in " Preparing HVAC Systems
Before Reoccupying a Building " on page 22. For information on the
ASHRAE Epidemic Task Force's building readiness guidance, visit
https://www.ashrae.org/technical-resources/building-readiness.
When thinking about maintenance, applying best practices to installing and servicing heat pumps can help prevent refrigerant leaks. In
" Preventing Refrigerant Leaks in Heat Pump Systems " starting on page
36, the authors also discuss the importance of harmonization between
standards-setting organizations, manufacturers' requirements, engineering specifications and contractor training.
Ensuring a building's systems work as intended is the expertise
of building commissioners. The work isn't without risk, and " What
Insurance Do Building Commissioning Providers Need " on page 14 discusses commissioning as a professional service and the need to assess
risks and liability and acquire the appropriate amount of insurance.
Buildings are for people, but often little thought is given to how occupants interact with a building's interfaces. " How Building Interfaces
Affect Occupant Experience " on page 28 delves into the benefits of
thoughtful design, which can simultaneously improve usability, occupant comfort and energy performance.
IN THIS ISSUE'S COLUMNS, Solving Problems discusses some of the
most common errors designers make when selecting and sizing boilers
and how to avoid these errors. Continuing its discussion of acoustics
from the last issue, Engineer's Notebook tackles learning to use architectural acoustics in engineering. A new online tool that can model the
fate of infectious aerosols generated within the built environment and
the potential impact of various control measures is explored in IEQ
Applications. Finally, Refrigeration Applications describes a new river
source heat pump project.
Enjoy the issue!
