Leveraging Thermal Comfort to Achieve High Performance

Can buildings be both comfortable and energy efficient? The Kendeda Building shows how the two can go hand in hand.

User control may seem antithetical to high-performance buildings: imagine the amount of energy that might be wasted when building occupants are able to adjust the thermostat or open and close windows at will.

Occupants who have perceived control of temperature, however, tend to be more comfortable in their environment. Is it possible for architects to design buildings that are high performance and allow occupants thermal control?

LEED v4.1: “Not a Structural Change”

Version 4.1 for BD+C and ID+C, coming out in December, is about creating “stepping stones,” not about changing the fundamentals.
by P.J. Melton

I sat down with Melissa Baker of the U.S. Green Building Council (USGBC) at Greenbuild to talk about LEED v4.1 for Building Design and Construction (BD+C) and Interior Design and Construction (ID+C). Baker is senior vice president for technical core. Here’s what I found out.

First, the timeline: USGBC will release a draft of the rating system in December. You’ll have a month to peruse that while they build up the registration and submittal infrastructure. The beta will start in January 2019.

The Sustainable Spec Language You Should Be Using

Selecting the greenest products doesn’t do any good unless strong specifications support your choices. Here’s some language you can use.
by Anne Hicks Harney

Editor’s note: Guest blogger Anne Hicks Harney, of Long Green Specs, is our partner in providing product vetting services. Harney offers guidance on writing green specs and on finding products for LEED v4, WELL, and beyond.

All of us in the design professions need to do a better job of prioritizing our product selections, but we also need to find a way to get our first-choice products into the actual building.

Can our EBOM v4 project earn 1 point for the Innovation: Occupant Engagement credit AND earn 1 point for the Innovation: Green Building Education credit? Or are projects limited to pursuing just one of these innovation options?

According to GBCI, both of these innovation credits can be earned on a single project. While the Green Building Education credit focuses on educating occupants about the benefits of operations and maintenance policies and procedures that the project has already implemented, the Occupant Engagement credit focuses on improving the performance of the building by enabling energy efficient behavior in building occupants. Therefore, a single project can earn two Innovation points for successfully documenting both options.

Can the same commissioning authority complete both Option 1 (enhanced commissioning) and Option 2 (envelope commissioning)?

It is common for the same company to complete both enhanced commissioning and envelope commissioning on the same project. Many commissioning firms have both MEP and building envelope specialists. The credit does not exclude the same individual from performing the fundamental, enhanced, and building envelope commissioning scopes—as long as they are experienced in the commissioning of these systems.

Our project’s custodial vendor is certified by the British Institute of Cleaning Science (BICS). Does this program qualify as a local equivalent for projects outside the U.S. (per Option 2)?

BICS likely does not qualify as an equivalent program as of October 2018 because it doesn’t include an inspection or verification process to confirm that certified contractors are implementing what the standard requires. In its current form, BICS should be thought of more as a training program, rather than a certification system. However, the program’s standards may change over time to include an auditing or verification component, which would help support equivalency under this prerequisite.
