2016 New York Energy Codes: Commercial Edition

Multifmily Buildings

Multifamily buildings greater than three stories follow the commercial section

It has now officially been over one month since the 2016 NYS energy code went into effect. In a recent blog post, we covered some of the significant changes for residential buildings in New York. In this post, we will explore the substantive changes made in the commercial code section, particularly with respect to envelope and air barrier requirements.

As a reminder, in this post, we are referring to retail, commercial, or larger than three-story R-2, R-3, or R-4 buildings. New York buildings can choose between one of two compliance pathways: ASHRAE 90.1 2013 or IECC 2015, by applying the appropriate state and city amendments. Prescriptive as well as performance options are available, depending on the chosen pathway. (more…)

Don’t Be Scared of LEED v4

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.

Examining Green Building Rating Systems

SWA_GREEN_BUILDING

 

Earning a green building certification is a significant achievement for a project as it represents a strong commitment to sustainability principles. When pursuing certification, it is essential to select the rating system best suited to your project type and performance goals.

In this blog piece, we will examine the anatomy of five popular green building rating systems, including their applicability to building type and a brief summation of typical advantages and challenges faced by clients pursuing certification. (more…)

Transitioning to LEEDv4

LEED v4 transition

Written by Anna Speed, SWA Sustainability Consultant

After 61% of those surveyed at Greenbuild 2014 replied that that they were not prepared, or were unsure if they were prepared for the inception of LEED® version 4 (v4), the United States Green Building Council (USGBC) announced that it would allow LEED users to register projects under the LEED version 3 (v3) rating system until October 31, 2016. The original date for LEEDv3 registration to close was June 27, 2015. The USGBC made their decision to extend the deadline based on their understanding that LEED users and members needed additional time to prepare for v4, which is more stringent and requires greater cooperation from manufacturers and suppliers.

As a result of the extended deadline, the USGBC offers projects the ability to pursue LEEDv4 credits while registered under the LEEDv3 rating system. One credit for example is Materials and Resources Pilot Alternative Compliance Path 84 where project teams can pursue the entire LEEDv4 Materials and Resources (MR) Category in place of the MR credits from LEEDv3. This includes Storage and Collection of Recyclables, Construction and Demolition Waste Management Planning, Building Life-Cycle Impact Reduction, Building Product Disclosure and Optimization (Environmental Product Declarations, Sourcing of Raw Materials and Material Ingredients), and Construction and Demolition Waste Management.

How to Get Started with LEED for Homes and Multifamily Midrise Certification

Step 1: Understand the LEED for Homes process

The U.S. Green Building Council developed the LEED® (Leadership in Energy and Environmental Design) for Homes™ and Multifamily Midrise™ Rating Systems to assess and validate residential green building practices.

The LEED for Homes and LEED for Homes Midrise certification process is outlined in this video provided by USGBC.

In addition to meeting the rating system requirements, every LEED Homes and Midrise project is inspected and tested during site inspections by credentialed LEED Homes Green Raters. Steven Winter maintains a team of 11 credentialed Green Raters serving 20 states including New York, Connecticut, Virginia, Maryland, Pennsylvania, New Jersey. Massachusetts, and more.

Lindenguild Hall: A Contemporary Approach to PV in Green Affordable Housing

Written by Katie Schwamb

The Lantern Organization’s Lindenguild Hall is a 104-unit multifamily residential project that provides permanent shelter for under-served populations in the Bronx. On-site supportive service programming, open-use learning and activity rooms, and outdoor leisure space provide an enriched living experience for tenants. Contributing to the programmatic requirements of both LEED® for Homes™ and NYSERDA’s Multifamily Performance Program (MPP), the building’s sustainable and energy-efficient design features include high-efficiency boilers, a high-performance envelope assembly, low-emission finishes, low-flow plumbing fixtures, and a water-efficient landscaping and irrigation system. While all of these design elements contribute synergistically to high-performance operation, there is one feature that distinguishes Lindenguild Hall from many other affordable and supportive housing projects in New York…its extensive photovoltaic (PV) array.

Lindenguild Hall - Green Affordable Housing

Lindenguild Hall – Green Affordable Housing

Located on the building’s high-albedo roof, this 66-module solar electric array captures energy to help power lighting, heating, and cooling systems within the building’s common spaces, while reducing overall demand on the city’s electrical grid. An advanced feature of Lindenguild Hall’s PV system is its capacity for online monitoring, which provides building managers with real-time results, including metrics for solar generation in kW (kilowatts) and the overall kWh (kilowatt-hours) generated to date. Availability of this data enables management to assess the positive impact of renewable energy systems on their building’s performance. Long-term implications of alternative energy production on building stock include reduced life-cycle cost and protection against municipal energy uncertainties. Though less quantifiable , installation of innovative green technology adds momentum to standardizing sustainability in affordable housing design.

Lantern Organization, a not-for-profit housing developer and service provider, operates by actively addressing housing needs and offering social initiatives to strengthen disadvantaged NYC communities. SWA’s Residential Green and Multifamily New Construction groups helped Lindenguild Hall navigate the LEED for Homes program and secure NYSERDA MPP incentive funds. Committed to delivering the greatest benefit to their residents, Lantern acknowledges the added value of incorporating green building features into their affordable projects. Increased energy efficiency and improved indoor air quality potentially translate to lower energy cost burden and decreased susceptibility to disease for low-income populations.

Where is it now: Greenbuild’s LivingHome

We’ve talked about this conference already this month, but we couldn’t leave out one of the coolest parts that one of our own SWArriors, Maureen Mahle, got to participate in – a modular green home assembled on the showroom floor at the 2014 Greenbuild Conference and Expo. SWA is a partner of the Greenbuild LivingHome which was created in collaboration with Hanley Wood, LivingHomes, Make it Right, and the International Cradle To Cradle Products Innovation Institute. This show home, which Greenbuild attendees got to tour, achieves an array of lofty goals that enable it to be supremely sustainable both for the environment and its owners.

Greenbuild LivingHome, led by California-based designer of green modular home, is the result of a unique integrated design process, utilizing designers, vendors, and building science know-how from all over the country. Today, vendors are using the home as an opportunity to showcase the latest and greatest in residential green building products, including Cradle to Cradle certified products and Forest Stewardship Council certified woods.

One of the stand-out LEED® features of the home is the commitment to durable, resilient construction. Other site features include:

  • Permeable paving to maintain an almost permeable lot for managing stormwater.
  • Framing was treated for pest resistance.
  • Termite barriers installed at base plates, and a non-toxic termite bait system surrounding the home.
  • Closed cell foam, used to insulate the elevated floor.
  • Continuous drainage plane directs bulk water down and away.

So where is the home now?
On its site in the Lower 9th Ward in NOLA, owned by the Make it Right Foundation, contributing to the city’s growing stock of green affordable housing. Make it Right is working to complete the home for occupancy in the next few weeks!
