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Working remotely with a project team across the globe, the Passive House team at SWA was tasked with retrofitting an outdated factory in Katunayake, Sri Lanka, into a Passive House certified garment manufacturing facility.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).

The Results Are in from the NYC Ice Box Challenge!

On April 21, 2018, two blocks of ice weighing exactly one ton each were placed into what appeared to be identical sheds in Times Square. The purpose? To measure how much each block would melt over a 30-day period, ultimately demonstrating the efficacy of Passive House construction methods.

The first shed, or Ice Box, was built to meet current NYC Building Code standards, which lack stringent requirements for building envelope performance. The second was constructed using building principles adopted from the Passive House Standard, including the utilization of high performance building materials, a superior airtight building envelope with advanced insulation, and triple-pane windows.

After 30 days of exposure, the Ice Boxes were publicly unveiled, and the results were exactly what building professionals had anticipated. The block of ice contained in the Ice Box constructed to NYC Building Code resulted in a final weight of 126 pounds, while the block of ice within the Passive House Ice Box weighed an astonishing 756 pounds, retaining 42% of its mass!

Sustainable Spaces for Seniors

Panelists and organizers at the “Sustainable Spaces for Seniors: Design for Aging and the Environment” event at Hafele’s NYC Showroom

On May 1st, 2018, Steven Winter, founder and chairman of Steven Winter Associates (SWA), and Harold Bravo, Accessibility Consulting Director at SWA, moderated an event at the Hafele Showroom to discuss senior housing in New York City and its relation to accessible and sustainable design. The event was organized jointly by the AIANY Design for Aging Committee (DFA) and the AIANY Committee on the Environment (COTE).

A panel of experts presented perspectives from architecture, real estate development, and municipal government, and discussed the challenges of designing sustainable, comfortable, accessible, and healthy buildings for the aging population in New York City. The panel included Kleo J. King (Deputy and General Counsel, Mayor’s Office for People with Disabilities), Isaac Henderson (Development Director, L+M Development Partners), Jack Esterson (Design Partner, Think! Architecture+Design), and Rich Rosen, AIA, LEED AP (Principal, Perkins Eastman).
