WASHINGTON DC – In March 2019 Hickok Cole officially joined a research consortium headquartered at the University of Oregon called the Institute for Health in the Built Environment. Members come from various backgrounds including architecture, engineering, academia, consumer goods and technology.

The Institute’s mission is to: develop new design concepts for the realization of healthy and sustainable inhabited space. We do this by forming unconventional collaborations that conduct research where architecture, biology, medicine, chemistry and engineering intersect and translate it into design practice through a consortium of invested industry partners with applied impact. This aligns perfectly with Hickok Cole’s own vision of doing work that matters.

The types of research this Institute undertakes is broad, it covers such varied topics as daylighting and sunlight’s effects on indoor microbiomes, circadian lighting and healthy aging, priobiotics and mechanical building systems and mass timber’s effect on human wellbeing, both physical and mental. For a full breakdown of the consortium’s work, as well as an overview on Hickok Cole’s research philosophy, please see a pdf of the 2018-2019 Build Health_Q3 Report.

The Institute’s yearly conference, Build Health, will be held in a few weeks in Portland, Oregon and we look forward to presenting the latest on both our mass timber projects and ongoing grant work for the DC’s Department of Energy and the Environment and the US Forest Service through the Wood Innovations grant program.

Previously, we wrote an ASID Transform grant to study the effect of plants versus free standing air filtration systems on carbon dioxide levels in a standard office building with the Institute. While this particular grant came very close to receiving funding, it did not move forward in 2018, we hope to revisit this experiment in future to increase the number of options for tenants inhabiting buildings with aging mechanical systems.

WASHINGTON DC – Hickok Cole is proud to announce that it has been awarded a 2018 USDA Forest Service Wood Innovations grant to study the use of cross-laminated wood components in structures slated to be built for Kingman Island & Heritage Island Park in Washington, DC. The firm led the development of a masterplan for the islands as part of a 2017 Planning & Feasibility Study funded by the District of Columbia’s Department of Energy and the Environment. The masterplan calls for a series of outdoor classrooms and a ranger station that will act a gateway to the islands. The goal is to create a unique educational and recreational asset for children and residents of the District, while contributing to an engaged community and a healthy, restored Anacostia River. The revitalization of these islands is a key part of the District’s 2018 “Year of the Anacostia” campaign, and building the park elements out of a renewable resource aligns with the overall spirit of these rejuvenation efforts.

The Hickok Cole team’s winning proposal is one of 34 projects selected to explore the expansion and acceleration of wood products and wood energy markets across the country. “These Wood Innovation grants advance state-of-the-art solutions to reducing wildfire risk and making our forests healthier and more resilient,” said Forest Service Interim Chief Vicki Christiansen. “The public-private partnerships leveraged with these grants also foster increased economic development in rural communities.”

The grant includes funding from the U.S. Forest Service along with matching funds from the Softwood Lumber Board and in-kind donations from the team of industry partners, including Oehme, van Sweden, Skanska, Arup, VIKA, Integral Group and Smartlam. The award will be used to fund schematic and design development efforts focused primarily on the proposed Kingman Island Ranger Station. The team seeks to design a modular ranger station prototype for the National Forest Service that features a storage unit, office, breezeway, classroom and restrooms all built from cross-laminated timber (CLT) and other wood products.

“We want this to be a prototype that the National Forest Service can reuse throughout the country, using the modular components to scale up and down based on the needs of the individual parks,” said Holly Lennihan, Director of Sustainable Design at Hickok Cole. “The use of CLT in our design makes an environmental statement mere blocks from the Capitol, and creates a learning environment where children and lawmakers alike can be exposed to the sustainable potential of a domestic wood industry.”

A kick-off charrette, including representatives from the Softwood Lumber Board, WoodWorks, and the U.S. Forest Service is scheduled for July 24th at Hickok Cole’s offices in Washington, DC.

CURBED PHILADELPHIA — If the Philly skyline brings to mind one thing, it’s glass—and lots of it. From the Comcast Center to the two Liberty Palaces, many of the city’s tallest buildings are sleek, all-glass structures. But a group of DC architects say it’s time to bring another, environmentally-friendly material to the city’s skyline: wood.

 

PHILLY VOICE — “When you think of a skyscraper, you’re usually dealing with steel or concrete,” said Sean McTaggart, project architect at Hickok Cole. “The problem with those two materials is that they cause a lot of carbon emissions.” McTaggart and his colleagues recently submitted their dazzling Timber Towers project to the Skyhive Skyscrapers Challenge, a conceptual design competition that encourages entrants to showcase their creativity within the realm of what can actually be achieved.

 

A Stroll through Timber City with Holly Lennihan

Over the past few months, there has been a steady stream of conversation and research around the office related to the subject of mass timber and its application in building design and construction. The stars (and wood!) aligned in mid-July when our own Director of Sustainable Design and DC CREW EDU committee member, Holly Lennihan, joined The National Building Museum’s Timber City Exhibit, Forestry experts and other industry representatives for a panel discussion on the topic as a part of CREW DC’s “Innovation” education series.

Following the program, we sat down with Holly to discuss this growing trend, its application, and the design implications of using mass timber.

Why was mass timber a timely fit for CREW DC’s “Innovation” series?
The idea for the program originally grew out of conversations I was having with people in our office. This trend represents an exciting new way to use wood in our industry, and not many firms have experience designing and building with mass timber therefore our list of potential panelists was limited. However, through CREW EDU committee members, we were able to connect with both Melissa Jenkins of the U.S. Forest Service and Nadine Block of the Sustainable Forestry Initiative. Lauren Wingo, structural engineer at Arup, joined the team on the heels of a presentation Arup gave on mass timber to the Hickok Cole office. She was an integral part of their presentation, and we knew she would bring a lot of value to the program.

What innovations and advancements have been made to make building with wood in urban areas safer than the approach has been in the past?
During the panel, Melissa spoke specifically about the extensive safety testing. As I understand it, when a Cross Laminated Timber column or beam burns, a fascinating thing happens where the outside layer chars and actually insulates the inside. So, counter to what you would think, the burned exterior becomes the protection for the interior. According to Melissa, everyone who watched the fire test was stunned by how well the timber performed.

In addressing seismic issues, Cross Laminated Timber is a surprisingly effective structural system due to the process of laminating in two different directions. This technique results in ductile behavior, giving the structure flexibility and allowing for energy dissipation because the timbers can move against one another.

“Why not strengthen the wood production industry through investment in mass timber material? It supports domestic manufacturing while both helping the environment and contributing to beautiful interior design. I predict we will even see productivity gains in people who work in spaces where the wood structure is visible. To me, it resonates across the triple bottom line—a win-win-win for people, planet and profits.”

How is Cross Laminated Timber addressing established North American building codes that bar against the use of mass timber in high-rise development?
The 2015 International Building Code (IBC) allows for Cross Laminated Timber, but it has not yet been adopted by DC or Virginia. There are, however, alternate paths for incorporating mass timber in the meantime while complying with current codes. Lauren shared an example where Arup was able to use mass timber in their approach to Washington Latin Public Charter School’s new gymnasium; they walked the Department of Consumer and Regulatory Affairs (DCRA) through a process to show them how Cross Laminated Timber can meet fire and structural requirements for the code. This was, of course, aided by the fact that the material is included in future versions of the IBC.

Once there is a developer on board that understands that building with this material has valid economic rationale, while also giving them an edge in terms of their product offering, we anticipate others will follow. Hines has already successfully delivered a mass timber high-rise office tower in Minneapolis. At Hickok Cole, we’re excited about the opportunity to work alongside developers who want to be at the forefront of this kind of innovative work.

Are there sustainable or aesthetic benefits to building with wood over other materials?
From an aesthetic and wellness angle, there are benefits to taking a biophilic, human-centered approach to design. We are finding more and more connections between natural building materials and productivity, health and wellness. Plus, exposing the natural wood makes for a beautiful interior.

Nadine did a really good job of explaining the role of culling to maintain healthy forests. This necessary clearing results in a supply of timber that can be used throughout the built environment. Others are using wood from forests that have been decimated by the Mountain Pine Beetle, an epidemic brought on by climate change that is currently ravaging the West. Both approaches are helping to keep forests healthy and repurpose excess wood into a useful building material.

Are there financial benefits for developers that choose to go the mass timber route?
I think people that have used it successfully point to its ease of use and the resulting increased speed of construction. Anytime you can cut down on construction time, you are going to have a net gain in terms of expenditure and budget. Additionally, the fact that it’s a lighter weight material means a decrease in foundation costs.

As a designer and architect specializing in sustainability, why do you think mass timber is something DC—and the rest of the country—should be focused on right now?
For one thing, DC’s incredibly committed to sustainability. I think design professionals like myself feel that if there’s one place mass timber could enter the market, it’s here. We are looking for clients – whether it’s a developer or a mission-driven non-profit – to see the benefits of Cross Laminated Timber and be an agent of change.

However, we do have to be realistic. I think there are design constraints which could make it difficult to convince a central business district developer who wants to do a concrete and steel building to go the mass timber route. On the other hand, people may find new ways to use it. I’m both pragmatic and idealistic. I believe the use of mass timber will ultimately result in a better building, but it doesn’t have to be an all or nothing approach.
