Wishing You a Sustainable-ish Holiday Season

Whether you’re a Clark Griswold or an Ebenezer Scrooge, it’s that time of year again: the holiday season is upon us.

Even those of us who try to live a greener, more eco-conscious lifestyle have a tendency to abandon ship and surrender to the flow of unabashed consumerism and waste in the name of “just getting it done.” It’s hard to put added pressure on ourselves to be mindful of our environmental impact when there are gifts to be purchased, cards to be sent, stockings to be hung, and photos of dogs in Santa hats to be taken.

But you don’t need to do it all to have an impact.

Find one or two ways to improve your holiday traditions by making them greener. Perhaps pick the ones that justify you doing less work in the name of the environment (Reusable bags instead of gift wrap? Yes please). Think of it as a gift to Mother Earth or humanity, or as a way to further annoy that aunt who just can’t understand why on earth you would want use cloth diapers. Sigh.

Here are some ideas, tips, and tricks to help you be just a little more sustainable this holiday season:

Innovations in Accessible Products

Our accessibility consultants are constantly on the lookout for improvements in product design that will make it easier for our clients to comply with accessibility criteria. As manufacturers become more familiar with accessibility requirements under applicable federal, state, and local regulations and building codes, a number of innovative, accessible products have emerged to make compliance simpler and more stylish.

Here are just a few examples of accessible products that we have been recommending recently…

Recovering from Heat Recovery Woes

The International Energy Conservation Code (IECC) has a number of requirements involving energy recovery on ventilation systems. Requirements vary based on climate zone, building type and size, equipment capacity, and equipment operating hours. As a result, many new construction projects must now incorporate energy recovery considerations into their design.

An energy recovery unit (ERU) equipped with a heat wheel can be a great way to satisfy these energy recovery requirements. The ERU can be a roof-mounted air handling unit, or can be an air handling unit located inside a mechanical room with outdoor air and exhaust streams ducted in. The heat wheel is positioned so that half of the wheel sits in the exhaust air duct and the other half sits in the outdoor air intake duct. During cold weather, the wheel spins, transferring heat from the exhaust stream to the outdoor air intake stream. During hot weather, the wheel transfers heat from the outdoor air intake stream to the exhaust stream. In both cases the heat exchange enables the building to take advantage of the more comfortable conditions of the exhaust air, while still allowing fresh air to enter the building. During extreme weather conditions, heat wheels can save energy on space conditioning while still allowing for healthy indoor air quality.

When the Rubber Meets the Road

 

As the Passive House standard continues to make waves across New York City and the U.S., an entirely new design process has evolved to respond to the challenges of higher insulation levels, balanced mechanical ventilation, and perhaps the most difficult hurdle – an air tightness level that most would think is impossible. For the recently certified Cornell Tech building on Roosevelt Island, the tallest Passive House in the world, a several year-long coordinated effort was required to achieve such a feat. So what is the requirement, how is it measured, and what are the strategies and considerations required to achieve it?

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
