Building energy efficiency labels are now available for property owners of large NYC buildings to download and post in their lobbies. Each year, the labels will be available on October 1st and must be posted by October 31st. Failure to display the label for applicable buildings by the October 31st deadline will result in a violation from the Department of Buildings and fine of $1,250.
Integrating Social Equity into Green Building – Part 2: Pre-Design Phase
The social and environmental context can vary greatly from one project to the next. To achieve social equity goals, a well-constructed plan for all project phases must be created and tracked. And, although the measures are not generally complicated, they can be numerous. In order to promote social equity, SWA has compiled this series of blog posts that teams can refer to as a guide to help facilitate the process. The goal is to help project teams understand, identify, and incorporate social and environmental goals and strategies into projects in a holistic and integrated way.
The following outline provides an overview of steps the design team can take in evaluating projects during Pre-Design. Throughout, references to LEED credits are cited.
Integrating Social Equity into Green Building – Part 1: “Just Sustainability”
The causes of social inequity and injustice are deeply rooted within the systems that shape our society, including the built environment. The built environment represents the literal foundation of our society’s presence in the world – from the smallest rural community to the largest city. The way in which buildings are designed, constructed, and maintained has a tremendous influence on the equity (or inequity), and the justice (or injustice), of our society. The way we build and the strategies we employ can either continue to worsen social issues or can lay the groundwork for significant progress to be made on these issues in places around the world.
The building industry continues to make progress on reducing negative environmental impacts of the built environment. In fact, we’re increasingly seeing practices and strategies go beyond “sustainable” to “regenerative,” with such goals as net-positive energy, water, and waste. Now, the industry is reckoning with the urgent need to integrate social equity into its definition of sustainability in order to also reduce negative social impacts of the built environment. We might accelerate the process by framing the goal as “net-positive equity.” (more…)
Tech Notes: Sliding Doors at Dwelling Units
Private outdoor space is a desirable amenity for apartment dwellers, especially as COVID-19 restrictions have led to more time spent at home. Balconies and terraces accessed directly from multifamily residential dwelling units are increasingly popular with many of our clients, a trend we expect to see continue in the coming years. For designers looking to incorporate this feature, it is important to note that secondary exterior doors from dwelling units have specific accessibility considerations.
One of the most common problem areas that our accessibility consultants see in multifamily housing units are noncompliant secondary exterior sliding doors. The Fair Housing Act (FHA), as well as most building codes, strictly regulate these doors, from clear width and thresholds to door hardware at certain unit types. Our consultants highly recommend that swing doors are used in lieu of sliding doors at secondary exterior locations; however, if a sliding door is preferred, it is vital to consider the following requirements, among others:
Electrifying Central Ventilation Systems in Multifamily Buildings
A common strategy to provide ventilation in multifamily buildings is to design a central roof-top air handler that distributes outdoor air to each unit. The energy cost for this system, which commonly uses natural gas for heating for either a gas furnace unit or hot water from a central boiler is paid for by the building owner. However, there is another option – VRF. With the unprecedented rise of VRF technology in the last decade combined with regulations such as New York City’s Local Law 97 of 2019 (carbon emission penalty), the industry is taking a giant leap towards building electrification. There are always questions and concerns raised against building electrification ranging from initial cost to operating cost to reliability of the VRF technology. From the owner’s perspective, the biggest question is usually surrounding the operating cost of an electric system compared to a natural gas system for heating, but the cost of ownership must consider multiple energy metrics. I was curious to understand the impact on various building energy profile metrics associated with a Dedicated Outdoor Air System (DOAS) using the conventional gas fuel source vs. the latest VRF heat pump technology using electricity in a multifamily building. The findings of this investigation challenge the deep-rooted notion that electricity, being more expensive than natural gas per BTU, will always cost more to operate.
Pirelli Historic Retrofit: Part 1
One of the most important drivers in achieving Passive House certification (or achieving any goal!) is getting the project team involved from the start. Becker + Becker, the owner, architect and developer for the creative retrofit of the Pirelli Building, hired SWA’s Passive House, LEED, Enclosures, and Accessibility teams to coordinate during early design. Becker +Becker is invested in rebuilding for resilience, sustainability, and occupant health and comfort and appreciates the necessity of getting goals defined at the outset.
AeroBarrier: A New Tool for Gut Rehabs?
AeroBarrier is touted as the best route to never fail another blower door test. The technology, which involves pressurizing a space with a blower door fan while misting a water-based glue into the air from multiple points throughout the space, is most often being used on new multifamily buildings after drywall is installed. SWA first experimented with the technique on the Cornell Tech high-rise building. Back in March, I reached out to Yudah Schwartz at SuperSeal Insulation, Inc. about a personal project, the gut rehab of a 2,500 SF detached single family home. While renovations aren’t something they normally do, Yudah and his team agreed to try a demo. Here’s what happened.
The Numbers Are In! NYC Passive House Performance Data
In a collaborative effort that merged financing and energy use analysis, the New York City Passive House industry finally has performance data. Working together with Bright Power, The Community Preservation Corporation, and NYC Department of Housing Preservation & Development, this analysis is the first of its kind.
Why does this matter?
Energy Use Intensity (EUI) measures energy consumption on a per square foot basis to compare buildings and allows interested parties to gauge one building’s usage to another (or to a group of buildings with a similar use type). The study team compared the actual EUI of six completed Passive House-certified and Passive House-like buildings against recently completed multifamily code-built buildings. Information was gleaned from the EnergyScoreCards database and the Passive House (PH) target. The weather normalized data indicates the Passive House and Passive House-like buildings are performing much better than the comparable code-built group, but are not quite as efficient as the Passive House threshold. Industry leaders have recognized this performance gap – between predictive assumptions that rely on standardized patterns of use and the real-life habits of actual people living in the building. This gap has been a hot topic at the past several New York Passive House conferences. The results from the current analysis provide a starting point now, so the industry can focus on strategies to continue to reduce EUIs.
Trends in Healthcare: Charging Stations
“Trends in Healthcare” is a recurring series that focuses on exciting new designs and technologies we’re seeing in healthcare projects and provides best practices on how to ensure that these latest trends are accessible to persons with disabilities. We build on the wealth of knowledge we gain from working with healthcare design teams, construction crews, and practitioners to provide practical solutions for achieving accessible healthcare environments.
Anyone who has ever had to take a trip to the hospital knows how much time is often spent in the waiting room. As a result, our experience in that space can shape our perception of the entire visit. In fact, studies have shown that a visitor’s impression of the waiting room itself contributes significantly to the likelihood of a return visit. The length of wait times can vary – from a relatively short wait for a screening, to an average of 40 minutes in emergency departments, to the better part of a day if you are waiting for a family member to receive treatment. As healthcare providers strive to remove pain points within the patient experience, they are turning to a number of design strategies to help create a more pleasant waiting room experience. One of these strategies is to ensure that patients and visitors have access to electrical outlets.
Leveraging LEED for New Construction Post-COVID Part 2
LEED: Toolkit for a Healthy and Resilient Post-COVID Built Environment
At SWA, we have used LEED across a wide range of projects and contexts. We have seen firsthand its strength as an adaptable toolkit for guiding high performance building design, construction, and operation. The intent of each LEED credit category takes on a particular meaning, both locally and globally, in response to the emergence of such factors as global climate change and its associated consequences—including pandemics. In the post-COVID context, these intents will take on new meaning and new urgency. Read Part 1 of this blog here!
The overall goal of the LEED rating system is to reduce the negative impacts of the built environment on environmental and human health. Ideally, this focus contributes to our general, overall resilience to public health crises such as the COVID-19 pandemic by reducing and mitigating various factors that make us more vulnerable to diseases. For example, we know that long-term exposure to air pollution and poor air quality dramatically increases the chances of dying from COVID-19 and that most of the same pre-existing conditions that increase the risk of death for COVID-19 are the same diseases exacerbated by exposure to air pollution. Anything we can do to improve air quality will also improve our resilience to disease. Most significantly, we need to move away from fossil fuel-based energy and toward clean, renewable energy—and a large portion of LEED is focused on doing just that.
As researchers have noted, many of the root causes behind climate change also contribute to a greater risk of pandemics. An example is deforestation and associated habitat loss, which forces wildlife to migrate, bringing novel viruses into closer contact with livestock and humans, and increasing the odds of disease transmission. On top of that, by altering temperature and rainfall patterns, climate change has created conditions that are more conducive to the spread of disease in general. So, the strategies we need to enact now to address the climate crisis—many of which are addressed in LEED credits—can also mitigate the occurrence, scale, and impacts of future disease outbreaks.
