What is Co-Design, and How Does it Help Advance Equity Through Building Design?

Project teams may set out to design and construct a building that supports the needs of its occupants and the community as a whole. However, the design process does not typically involve examining the lived experiences of future occupants or the surrounding community.

This missing piece is called co-design, and it’s a crucial practice for creating healthy, safe, and equitable buildings.

Co-design is gaining traction as more project teams prioritize social equity and inclusion as part of their project goals. When community members and future occupants that represent diverse perspectives and lived experiences are part of the design process, the finished building is more likely to support the needs of building occupants.

Read on to learn how project teams are successfully implementing co-design to advance equity through building design. (more…)

Understanding Accessibility: Notable Changes in the 2022 New York City Building Code

As of November 7, 2022, the 2022 edition of the New York City Building Code is now in effect. As designers begin to work with the updated code, our accessibility consultants have been getting a lot of questions about what has changed from the requirements in the 2014 edition of the code.

Cover of the New York City Building Code.While it is important to read through the new code in its entirety to ensure compliance with all updated criteria, we have compiled a list of some changes related to accessibility that designers should be aware of, below.

SECTION BC 1106: Parking and Passenger Loading Facilities

8 Electric Vehicle Charging Stations

While the 2014 edition of the code was silent on specific requirements for electric vehicle parking, the 2022 edition provides scoping and technical criteria for charging stations and the parking spaces serving those stations. Where EV charging is provided for common use, at least 5%, but no less than one of each type of EV station must be accessible. (more…)

Getting Ready for the 2024 IECC: The Requirements Proposed for Residential Buildings

Each state in the U.S. can adopt its own residential building code. States tend to use a specific edition of the IECC as their residential code (with the exception of California). And while 2022 is nearly over, only a few states have adopted the 2021 IECC.

However, several more states are likely to use the 2021 IECC given that under the Inflation Reduction Act, an additional $1 billion has been allocated to support jurisdictions in adopting the 2021 IECC or its zero-energy appendices.

Due to its lack of country-wide adoption, most building professionals might not be familiar with the 2021 IECC as it compares to the current codes in the states where they work. For example, there are significant increases in the minimum insulation requirements, changes to the air leakage test thresholds, and a new section, R408, with requirements to achieve “additional efficiency” through the selection of “packages.”

Sustainable Buildings Are Healthy Buildings: How to Design and Maintain a Healthy Built Environment

What is a sustainable building? We know it must be an energy-efficient, high-performance building and emit as little carbon as possible to protect the environment. But a sustainable building must also be a healthy building that protects people and communities.

A building can’t be considered sustainable if it doesn’t sustain the physical and mental health of all its intended occupants and sustain the community around it.

Healthy buildings require a holistic approach that accounts for how every building material, system, and technology affects the wellbeing of occupants.

This is an important topic at SWA, so we asked our interns to explore it! They talked to our experienced building systems, sustainability, and Passive House consultants and put together this blog post as a resource on designing and maintaining a healthy built environment.

Keep reading to learn more about the following considerations for healthy buildings:

  1. Occupant comfort and productivity
  2. Optimal indoor air quality (IAQ)
  3. Ventilation system upgrades in existing buildings
  4. Healthy building certifications (Fitwel, WELL, etc.)
  5. Building operations and maintenance staff training

Montgomery County, MD, Has a BEPS. What Do You Need to Do Now?

Montgomery County, MD, passed Bill 16-21, which creates a Building Energy Performance Standard (BEPS) for buildings within the county. The law also expands benchmarking requirements within the county, requiring private and Montgomery County-owned buildings over 25,000 square feet to benchmark energy use no later than June 1, 2024, in advance of demonstrating energy performance in the future.

Montgomery County BEPS: What We Know

Montgomery County’s BEPS phases in across different groups of buildings between 2024 and 2027. Each group will have 10 years to meet the BEPS for their particular building type.

Most importantly, each building will need to demonstrate that it meets the BEPS. All but the highest-performing buildings over 25,000 square feet may need to take some action. (more…)

What Would a Passive House New York City Look Like?

New York City: the city that never sleeps—and where buildings account for approximately two-thirds of greenhouse gas emissions.

In 2019, New York City Council passed Local Law 97 (LL97) to hold building owners responsible for carbon emissions. The goal is to reduce over time, eventually reducing emissions 80% by 2050. As it stands, the law applies to most buildings over 25,000 square feet, which is roughly 50,000 residential and commercial properties across the five boroughs.

One pathway to decarbonize New York City’s buildings is using the Passive House standard: a high-performance building standard that significantly reduces whole building energy consumption by up to 60-70% while providing superior comfort and indoor air quality. When coupled with renewable energy systems, Passive House makes net zero energy buildings more feasible. (more…)

Choose Your Adventure: Constructing New vs. Adapting Old

Carbon emissions from new construction graphTo meet the goals of the Paris Climate Agreement, we must make decisions that will result in the greatest near-term carbon savings. This means taking into account both embodied carbon—those upfront emissions associated with the extraction, manufacture, transportation, and assembly of building materials—as well as the carbon that’s emitted over the course of the building’s operational phase.

We can build a high-performance building with very low operational emissions, but if its embodied emissions are so high that even if it’s a net-zero energy building (meaning it has net-zero operational energy consumption) it would take decades for the building to reach net-zero carbon (meaning it has net zero whole-building lifetime carbon emissions), we’re not actually helping to solve the critical issue of near-term carbon.

Utilizing Enterprise Green Communities to Drive Equity in Affordable Housing

EGC logoIs Sustainability only for the wealthy? While staring at the double-digit price of organic tomatoes at the local farmers’ market I am inclined to think sustainable is synonymous with exclusive. Unfortunately, many things labeled “sustainable” or “eco-friendly” seem not to be within everyone’s budget. A society where the cost of a Tesla is the average annual income of a household easily convinces us that making sustainable choices comes with a cost many can’t afford.

The ”green” housing industry is no different. Walkable and well-connected neighborhoods, where residents can enjoy abundant services are often the pricey neighborhoods. Toxic-free natural materials, daylight, fresh air, and even living green walls fill the homes of the wealthier and healthier tenants, while high-efficient mechanical systems and solar panels provide (almost invisible) energy savings as compared to their sky-high rents.

On the other side, low-income families are often located in neighborhoods at the edges of cities where community services and fresh healthy food are out of reach except by driving, and where parks and options to catch some fresh air are far and rare. Here the apartments are more likely to be exposed to toxic materials, increasing chances to develop asthma or other diseases. Energy bills are often high with little opportunity to get any lower by using newer energy-saving appliances and equipment.
