The envelope of a Passive House building is designed to be significantly airtight. Mechanical ventilation systems introduce fresh, filtered air and exhaust stale, contaminated air 24 hours a day—which is extremely important in maintaining optimal indoor air quality and occupant comfort.

As the saying goes, build tight and ventilate right.

When ventilation systems are designed correctly, but installed, commissioned, or operated incorrectly, the system ends up being leaky and inefficient and uses more energy than expected.

Project teams for Passive House buildings must find solutions for these implementation and commissioning hurdles, or the potential energy penalty can adversely effect the building’s high-performance design intent.

What happens when a Passive House construction expert and a commissioning engineer collaborate to find a solution to common ventilation system issues that cause excess energy use? We, the authors of this blog post, did just that!

Keep reading to learn about common construction issues with Passive House ventilation systems and five lessons learned based on our experiences in the field. (more…)

Over the lifespan of a building, operations and maintenance staff arguably have the biggest impact on system performance and energy efficiency. With the right training, staff can keep a building running as it was designed to run and “create the change” to reduce energy usage, reduce repairs, and upgrade vs. replace equipment.

So how do project teams create O&M training programs that achieve all this?

In this episode, producer and guest host Dylan Martello chats with Luis Aragon and Heather Nolen—two O&M training experts at SWA—about balancing in-person and digital education, accounting for every learning style, breaking down language barriers, sustaining the training for the long term, and much more.

Access to sustainable and healthy buildings should be a universal right. Unfortunately, underserved communities and low-income families often face significant barriers to living in buildings that are efficient, supportive, and resilient.

The Enterprise Green Communities (EGC) certification program provides criteria to create sustainable, healthy, and affordable housing and offers a pathway our industry can use to advance equity in the built environment.

Thirty-one states, plus Washington, DC, require or encourage developers seeking affordable housing funding to follow the Enterprise Green Communities Criteria.

However, any housing development in the U.S. with affordable homes can earn the Enterprise Green Communities certification. (Projects that achieve the 2020 EGC certification also receive WELL certification.)

In this blog post, we’re sharing the strategies we use most often as EGC consultants, along with a common challenge and solution, to achieve certification and create more sustainable communities. (more…)

The Americans with Disabilities Act (ADA) was signed into law on July 26, 1990. This federal civil rights law prohibits discrimination based on disability and declares that people with disabilities must have equal access to all areas of public life, including employment, public services, public accommodations, and telecommunications.

One year later, on July 26, 1991, the Department of Justice released the 1991 ADA Standards for Accessible Design to be used in the design and construction of new and altered buildings. These technical standards have since been replaced with the 2010 ADA Standards for Accessible Design that we use today.

Despite the importance of the ADA and its enforcement over the past three decades, there are still misconceptions about what the law requires for buildings and facilities.

Below are five of the most common misconceptions that SWA’s accessibility consultants encounter when working with building designers, developers, and owners on ADA compliance. (more…)

What happens when you put four sustainable building experts involved in energy code development in a room and ask them to bring their favorite—and sometimes, most controversial—topics for discussion? You end up with more questions than answers!

In this roundtable episode hosted by Robb Aldrich, our guests ask each other these tough questions related to our nation’s energy codes:

• Performance Metrics: How can energy codes be simplified? Is energy use intensity (EUI) a viable alternate metric?
• Gas Bans: If jurisdictions cannot ban gas, how can we put electrification in the energy code?
• Embodied Carbon: How should embodied carbon accounting be incorporated into energy codes?
• Robb’s Bonus Question #1: How are building inspectors dealing with complicated energy codes?
• Robb’s Bonus Question #2: Should there be electric vehicle (EV) charging requirements in energy codes?

Medical diagnostic equipment is instrumental to the accurate and timely diagnosis of a patient’s health conditions, but people with disabilities are often met with challenges when accessing and using diagnostic equipment. This can lead to omitted examinations or inaccurate results, thus causing greater health disparities among people with disabilities.

The Americans with Disabilities Act (ADA) and the 2010 ADA Standards for Accessible Design have made a significant impact on how architects and designers consider accessibility in healthcare settings.

Under Title III of the ADA regulations 28 CFR Part 36, hospitals are required to provide full and equal access to healthcare services and reasonable modifications of policies, practices, and procedures, as well as auxiliary aids and services. As part of this requirement, hospitals must provide accessible medical diagnostic equipment.

However, the 2010 ADA Standards do not provide technical guidance on what types of medical diagnostic equipment and how many of each type must be accessible to patients with disabilities. Because of this, the determination is often left up to the terms of settlement agreements.

How can designers and healthcare providers proactively ensure that medical diagnostic equipment is accessible to patients with disabilities? Keep reading for our recommendations. (more…)

Building industry professionals have made great strides in reducing operational carbon, but without losing ground, we need to shift our efforts toward building materials and embodied carbon.

The time value of carbon is the notion that reducing carbon emissions now provides a greater benefit than reducing the same amount of emissions in the future. In other words, action today is worth more than tomorrow.

We can envision a future where all building materials have low or zero embodied carbon—even carbon-capturing ingredients—and there is a plan for reusing and recycling materials at the end of a building’s useful life. But how do we get there?

Read on to explore data, resources, and tools available now to help project teams reduce embodied carbon along with operational carbon.

Embodied Carbon: How We Define It

There are several stages in a building’s life. The middle stage is when a building is in use, and it’s all about the operational carbon emissions that result from running—or using—the building. Addressing operational carbon has been critical to reducing greenhouse gas (GHG) emissions, and the building industry has made some progress. But important climate action opportunities are missed by focusing only on the middle stage. (more…)

Our accessibility consultants work with design and construction teams to ensure that facilities are compliant with the architectural accessibility requirements of applicable laws and codes. But once the building is operational, and management and maintenance is turned over to an entity not involved in the design and construction process, unintentional violations of accessibility requirements often crop up post occupancy.

It’s not uncommon for litigation to result from observations of violations made by testers that are caused by unknowing operations and maintenance staff.

Once a facility is complaint with accessible design and construction requirements, it must remain so for its life, so it’s important for everyone to understand how to maintain compliance.

Here are some of the more common violations of accessibility requirements that occur post occupancy: (more…)

New York City buildings over 25,000 square feet must display a Building Energy Efficiency Rating Label, as required by Local Law 33 of 2018 and Local Law 95 of 2019.

Each year, buildings are given new energy efficiency grades based on benchmarking data from the previous calendar year.

New labels are available to building owners every year on October 1. Labels must be downloaded and posted in the lobby of each building by October 31. Failure to display the label by this deadline will result in a violation from the Department of Buildings and fine of $1,250 for applicable buildings.

Keep reading to get answers to all your questions about New York City’s building energy efficiency letter grades and labels from our energy experts. (more…)

The ideal building is cost-efficient, energy-efficient, and comfortable for its occupants. But executing all three of these elements to perfection can be complex and costly. Can there ever be a win-win-win across all three?

In part two of our roundtable episode with Michelle DeCarlo, Saeideh Kirby, Erin McElwee, and Buildings + Beyond host Kelly Westby, our guests discuss how to find a balance between meeting project objectives and creating sustainable and healthy buildings. They also share how they’ve seen the COVID-19 pandemic change project priorities and building operations.
