255 S. King Street Achieves Long Awaited LEED Silver Certifications

255 S. King Street Achieves Long Awaited LEED Silver Certifications

Some large, phased projects have really long design and construction schedules, so it can take quite a while to guide them through the LEED certification process. One such project began for us in 2012, the 255 S. King Street Hotel and Office towers, which were constructed on a joint four story podium containing parking and pedestrian level retail space. Phase 1 began with a 325,000SF hotel project that consisted of 297 rooms with a conference center and a health club with a pool. During construction, a popular local restaurant, 13 Coins, relocated to the ground floor of the new building. Connected by an atrium, the second phase of the project added an 18 story, 292,000SF core and shell office tower to the podium. The office tower houses Avilara on several of the floors with some space yet to lease and contains a large roof top restaurant. Since the towers share […]

Westlake Steps Projects Get LEED Certified

Westlake Steps Projects Get LEED Certified

Congratulations to the Holland Partner Group for successfully LEED certifying both Westlake Steps 2 and 4. These large multifamily projects, located at 1207 and 1287 Westlake Avenue respectively, were built concurrently. To address steep terrain, each project is divided into two buildings stepping up the slope with an at grade walkway and hill climb between them. Below grade they are connected by shared parking. Completed first, the 310,000SF, 5-story Westlake Steps 4 project has 317 market rate units and achieved LEED Certification in the spring of 2017. It was quickly followed a LEED Silver Certification on the Westlake Steps 2, a 313,850SF 6-story project with a small groundfloor retail space and 385 market rate units. ArchEcology guided the LEED certification process for both projects.

Midtown21 – Started at Silver, Certified Gold

Midtown21 – Started at Silver, Certified Gold

We’re very excited that 1007 Stewart, dubbed Midtown21, was just awarded LEED Gold certification! The 21-story high rise, located in the Denny Triangle in downtown Seattle, has a 19 floors of office space, a Great Room for conference and meeting space, groundfloor retail and 7 stories of below grade parking. The project team pursued LEED Silver right from the start as part of the permitting process, allowing the early incorporation of extensive indoor air quality and energy efficiency measures. The building was leased to one office tenant before construction was even complete. And when the project attracted a buyer that was interested in LEED Gold, we were able to help the team successfully stretch to achieve the new goal.

ArchEcology’s 10th Anniversary

ArchEcology’s 10th Anniversary

ArchEcology celebrated 10 years of certified green buildings with an anniversary event on September 15th held on the 40th floor of the Premiere on Pine building. Against a backdrop of spectacular views, participants learned what it takes to successfully certify a building in the newest LEED rating system – v4- which becomes mandatory for all new registrations on November 1, 2016. The presentation we gave, called How to Succeed in LEED v4, can be found on our Resources page. If you’d like to hear it from us and earn AIA continuing education credits, get in touch and we’ll schedule a lunch time session for your staff.

LEED v4 and Low Emitting Materials – Part Two … Wet Applied Products

LEED v4 and Low Emitting Materials – Part Two … Wet Applied Products

Previous versions of LEED have treated low emitting materials as 5 separate issues each worth 1pt. In LEED v4, all of these categories (plus a new one) have been combined into one credit called Low Emitting Materials that is worth only 3 possible points. Emissions testing has become the primary protocol for all products, but wet applied materials still carry the previous VOC content requirement like a cherry on top. While compliance may seem more simplified, perfect execution in at least 3 product categories is required which means the bar is set pretty high. You’ll need some proactive strategies. Assuring compliance for adhesives, sealants, paints or coatings before LEED v4 meant comparing grams per liter of VOCs in the product against VOC limits set by California regulations or GreenSeal standards. A project could provide product data with VOC content and receive a thumbs up or down on its use. If […]

LEED v4 and Low Emitting Materials – Part One … The Overview

LEED v4 and Low Emitting Materials – Part One … The Overview

Indoor air quality has always been a hallmark of LEED certification, and the new LEED v4 rating system raises the bar significantly when it comes to low emitting compliance. Previous versions of LEED have treated low emitting materials as 5 separate issues contained in 5 separate credits each worth 1pt. Adhesives and sealants comprised the first credit, followed by paints and coatings, flooring systems, composite wood and then systems furniture. Among the 5 credits were 3 different approaches to measuring low emissions based on product category – VOC content in grams per liter (g/l) for wet applied products, third party emissions testing for flooring and furniture, and no addition of urea formaldehyde to manufacturing of composite wood products. In v4, all of these issues have been combined into one credit called Low Emitting Materials that is worth a total of only 3 possible points. And the credit scope has grown […]
