It’s all in the Details: Designing for Passive House & Accessibility Compliance

The number of multifamily residential projects targeting Passive House certification has been rising steadily over the past several years, bringing along many exciting challenges. This has been especially prevalent in New York City, where increasingly stringent energy standards and a desire for innovation have made designing to Passive House standards an attractive goal. As the number of these projects passing through our office continues to grow, we have discovered some important overlaps with one of our other consulting services – Accessibility Compliance.

In the United States, multifamily new construction projects consisting of four or more dwelling units are subject to the Fair Housing Act, as well as state, city, and local accessibility laws and codes. For the purposes of this blog we will focus on projects in NYC, although the majority of newly constructed residential projects across the country will be subject to some variation of the criteria discussed below, for both Passive House and Accessibility standards. With this in mind, we have chosen a couple of common problem areas that require particularly close attention. Read more

Why the Whole Building Approach Matters

At Steven Winter Associates, Inc., we support the whole building approach to design and construction by doing our best to ensure that projects meet sustainability, energy efficiency, and accessibility requirements, among other design strategies and goals. From our perspective, accessibility compliance is a key factor in determining whether a project is truly sustainable and efficient.

The Whole Building Approach to Design (from the Whole Building Design Guide, “Design Objectives”)

As an example, I was recently contacted by a New York City-based housing developer. They received a letter from an attorney stating that three of their recently constructed projects in New York City were “tested” and found to be noncompliant with the accessible design and construction requirements of the Fair Housing Amendments Act and the New York City Building Code. SWA toured the buildings and confirmed that the allegations were in fact true. We identified issues such as excessive cross slopes along the concrete entrance walk, the presence of steps between dwelling units and their associated terraces, the lack of properly sized kitchens and bathrooms, the lack of compliant clear width provided by all user passage doors, etc. It quickly became apparent to us and to the developer that the cost of the remediation required to bring the projects into full compliance would be astronomical.

High Performance Walls

Written by Joanna Grab, Senior Sustainability Consultant

Groggy and sleepy-eyed, I swung my feet out of bed this morning. Still waking up, I began the trek to my coffee pot, but was thrown off track when my bare feet stumbled (literally) upon a freezing patch of floor beside the door to my balcony. Suddenly wide-eyed, I ducked into the bathroom to rub my toes against my fuzzy bath mat. Outside, the city seemed to have surrendered itself to a single shade of gray, and though my feet were warming, I could feel the monochromatic January cold pressing its way through the metal window. I put on my architect’s (hard) hat and thought, “these are textbook examples of thermal bridging.” But aside from a chill or a draft here and there what’s the big deal? Well, let me provide a little insight.

Thermal bridging occurs when heat is lost through a less-insulated or more-conductive portion of a building’s exterior. On a frigid winter day, this means heat is lost where insulation is lacking, such as through a metal window frame or the floor slab in my apartment building. Ultimately, thermal bridging results in a less comfortable home that is more expensive to heat and cool.

Another hidden concern is condensation, which can be a consequence of thermal bridging. When warm air comes into contact with a cold spot on the floor or wall, water vapor in the air cools and collects as droplets on the colder surface. This can result in durability problems, as well as poor indoor air quality.

Don’t Be Scared of LEED v4

Written by Marina Dimitriadis, Sustainability Consultant

LEED v4 Changes and Updates

leedv4picleedarticleghostpicWe all knew the time was creeping up on us when LEED v2009, known as LEED v3,would no longer be an option. There are plenty of Halloween ghouls about, but LEED v4 shouldn’t give you a scare! We have a few key resources to help you understand the new rating systems and ensure a smooth transition.

LEED v3 Sunset and Registration Dates

All projects that wish to pursue LEED v3 must register  by October 31, 2016. Additionally, LEED v3 projects must certify by June 30, 2021. Projects that register now under LEED v3 can always transition to LEED v4 at no cost, but you can’t switch back to v3 after 10/31/16.

The POWER of Partnership!

PowerDownDC logoHoriz (4)

In partnership with the District of Columbia’s Department of Energy & Environment (DOEE) and the Institute for Better Communities (IFBC), SWA is implementing DC’s first multifamily housing energy and water challenge.

What is the POWER DOWN DC Challenge?

POWER DOWN DC is a 4 month building-to-building, education focused competition in Washington, DC with a goal of empowering  building residents and staff to change behavior and reduce overall energy and water usage. Residents compete as a building team against  other apartment buildings to hit a reduction target and strive to make the greatest overall  reduction.

Driving Savings through Friendly Competition

The basic concept is simple: bringing people together for friendly competition is more likely to encourage meaningful action than simply providing information about energy and water efficiency alone. By joining the competition, participants try to reduce their own energy and water use and help members of their apartment community  do the same. Residents will be encouraged to make a commitment to efficiency and take simple steps every day that collectively will have a big payoff. Actions like turning off lights, fixing a leak, and taking shorter showers, multiplied across dozens of apartment units will have quick results. In DC, residential buildings make up 20% of total energy use and 23% of total water use.  If all multi-family residents take action, we can save 83,000,000 kilowatt hours (KWH)  of energy, 96,000,000 gallons of water, and $31, 400,000 dollars annually. Small steps = big savings.
