The Top 10 Party Walls Posts of 2018!

2018 has been a year to remember for SWA’s Party Walls blog. Our consultants have shared their passion for high performance buildings by recounting stories from the field and providing information, new findings, and best practices to improve the built environment.

Whether discussing topics based in New York City or Southeast Asia, here are our fan favorites from 2018…

Multifamily Green Building Certification Program Comparison

If you’re designing and constructing multifamily buildings, chances are you’ve run into one of the many green building certification programs. Whether mandated by code, tax credits, your loan, or because you want to improve building performance, the differences between programs can be difficult to understand. One of the most frequent questions we help design teams answer is “which multifamily green building program should we choose?”

To help shed some light on the major green building standards, we’ve outlined some of the most important requirements for multifamily building performance that tend to differentiate the programs the most.

ENERGY STAR

Administered by the U.S. Environmental Protection Agency, ENERGY STAR is a free program that includes envelope, mechanical, and moisture management requirements. There are two pathways to certification – ENERGY STAR Certified Homes and ENERGY STAR Multifamily High-rise – based on the height of the building. In the near future these programs will merge into one Multifamily New Construction standard.

Although it isn’t considered a full green building program (it doesn’t address materials, site or water), ENERGY STAR is included in this comparison because several programs and standards reference it as a base requirement.

Just Your Typical Blower Door Test… in Sri Lanka – Star Garment Innovation Center

As the number of projects pursuing Passive House certification increases, so does the demand for whole building blower door tests. And so, performance of recent blower door tests took us to uncharted territory, not only for SWA, but for the Passive House Standard.

Working remotely with a project team across the globe, the Passive House team at SWA was tasked with retrofitting an outdated factory in Katunayake, Sri Lanka, into a Passive House certified garment manufacturing facility. Jordan Parnass Digital Architecture (JPDA) recruited SWA to provide technical assistance to the project team. Responsibilities for this project included Passive House design analysis and recommendations, mechanical design review, energy and thermal bridging modeling, and the testing and verification necessary to achieve certification from the Passive House Institute (PHI).

Delos Headquarters Raises the Bar for Healthy Buildings

A team of SWA consultants recently had the opportunity to tour the newly constructed Delos Office Headquarters, located in the Meatpacking District of New York City. The office, which occupies the fourth and fifth floors of a ten-story building adjacent to the High Line, has obtained WELL Platinum certification through the International WELL Building Institute (IWBI), Petal Certification through the Living Building Challenge, and is currently pursuing LEED v4 Platinum certification through the US Green Building Council (USGBC). From the inception of the tour, it was clear that the space had exceeded the expectations of these certifications, and more.

Overview

Stepping off the elevator, occupants walk over a large metal grate designed to remove debris from shoes, preventing dirt and other particles from contaminating the floor. Then, upon entering the office, visitors are immediately greeted with an abundance of natural light and sense of biophilia. The office is enclosed by large glass curtain walls and filled with an array of plant life. Next to the entrance, a large monitor displays office conditions, such as temperature, humidity, carbon dioxide, and other levels affecting tenant comfort.

The main office area is largely free address, which means employees can freely move to where they feel most comfortable. Each desk is adjustable and includes a monitor, a temperature adjustable task light, and many other utilities that foster productivity. There are greenwalls placed throughout the office (22 to be exact), which are used to purify the air. Clean air is also distributed through floor diffusers and dirty air is removed through the ceiling. Additionally, it is noticeably quiet in the office; the mechanical systems are well insulated and there is a low level white noise sound masking system that lessens harsh noises.  Read more

Pathways to Passive House Certification

Passive House logosDid you know that there are two pathways for earning Passive House certification? There’s Passive House International (PHI) and Passive House Institute US (PHIUS). Using an energy modeling software, both programs evaluate a building based on a variety of factors. Despite the misleading moniker, certification is not limited to just housing. In fact, building types from residential and commercial high-rises to industrial factories have earned Passive House certification around the globe. However, the two certification programs are run by separate institutions, using different energy modeling software and standards. However, both ultimately maintain the shared goal for high performance, low energy buildings.

Historically, around 2013, the PHIUS organization developed a new standard called PHIUS+ 2015 with a climate-specific approach and an alternate modeling software. Starting in March 2019, PHIUS projects will be held to updated requirements under the PHIUS+ 2018 program.

PHI also offers project and climate specific cooling demand thresholds, having previously begun offering alternate certification options in 2015. Additionally, PHI created a program called EnerPHit to provide more flexibility for retrofits. PHI recognizes buildings that exceed its standard certification by offering Plus and Premium certification, as well as a Low Energy Building certification pathway for projects that are near PH efficiency.
