New NYC Buildings Report Shows Progress On Efficiency
On August 24, the New York City Mayor's Office, along with the Urban Green Council and New York University's Center for Urban Science and Progress released "New York City’s Energy and Water Use 2013 Report," a comprehensive analysis of data which focuses on 2013 energy and water usage of buildings in New York City reported in 2014.
The analysis in the report finds that between 2010 and 2013, greenhouse gas emissions from 3,000 consistently benchmarked properties with a 100 percent compliance rate
—which includes zero gaps between benchmarking periods
—dropped by eight percent, while energy use decreased six percent.
To continue progress on these encouraging data findings, the report identifies several opportunities for energy savings and builds upon the findings of the City’s One City: Built to Last Technical Working Group Report released in April
—which include improving heating system efficiency, preventing energy losses from window and wall air-conditioning units, and updating lighting and installing lighting controls.
"New York City’s Energy and Water Use Report represents another significant step forward in using rigorous data analytics to yield actionable insight that supports urban sustainability and long-term energy efficiency,” said Professor Constantine E. Kontokosta, Lead Researcher for the Data Analysis at NYU’s Center for Urban Science and Progress and Tandon School of Engineering. “The Mayor’s Office of Sustainability has once again demonstrated the value of a data-driven approach to reducing energy use and carbon emissions from buildings, and the potential for innovative, evidenced-based policies to drive real change."

IMT and DCSEU Release Plug Load Management Study
New Recording: Running an Energy Benchmarking Help Center
As an environmentally conscious landlord, The Tower Companies (Tower) implemented a number of energy conservation measures at The Millennium Building, a multi-tenant office building in Washington, D.C. To go beyond base building improvements and further reduce energy in tenant spaces, Tower sought plug load management expertise from IMT and the Waypoint Building Group, a software and analytics provider for commercial real estate. Plug and process loads (PPLs) such as electronic devices, appliances, and office equipment consume about one-third of primary energy in U.S. commercial buildings, equating to approximately $56 billion dollars in energy expenditures per year.
With funding from the DC Sustainable Energy Utility, IMT and Waypoint conducted research at The Millennium Building to assess the cost and impact on energy usage from PPL management strategies over a 105-day period. Aquicore sub-metered and provided energy management software to monitor plug loads, and TrickleStar provided advanced power strips for the experiments.
For the commercial real estate market, the resulting study, "Increasing Tenant Engagement Through Plug Load Management," presents PPL strategies and their associated energy savings, while also exploring the most cost-effective pathways to implementation. The study is meant to highlight the process and opportunities of PPL management rather than define a standard economic outcome, as several variables could affect the outcome on a case-by-case basis.
In August, IMT hosted "Benchmarking Help Centers: Case Studies of Successful City and Third Party Partnerships," in an effort to share best practices with cities designing and implementing benchmarking and other similar energy efficiency policies and programs. IMT is exploring what the appropriate role is for benchmarking help centers, what resources are needed, and how cities can operate them to get the best results. For those who missed it, the full recording is now available on IMT's YouTube channel.
During this webinar, Jayson Antonoff, IMT's Associate Technical Director of Building Performance Policy, led a discussion on how some cities have served outreach and end-user support needs by relying strictly on internal staff, while others have chosen to work with an outside third party, to gain additional support and analytical capabilities. Other presenters included three cities and their partner organizations:
Each pair of presenters provided insights on how responsibilities have been divided up between the participating organizations, lessons learned through their experience, and potential future directions to maximize the impact of these programs while controlling costs. View the webinar.
EPA Adds Waste and Materials Tracking to Portfolio Manager
On August 8, the U.S. Environmental Protection Agency (EPA) announced the addition of waste and materials tracking to Portfolio Manager. EPA’s Office of Resource Conservation and Recovery and ENERGY STAR programs worked together to identify and develop metrics to make it easy for building owners and managers to track waste and materials.
Portfolio Manager now tracks 29 different types of Waste/Materials, everything from basic trash to cooking grease to appliances. Users can track each of these items according to one of four different “Waste Management Methods”:
- Disposed. (Users can further categorize Disposed Waste [trash] according to one of four “Disposed Waste Destinations: landfill; incineration; waste to energy; and other/unknown)
Users may also track the waste or material according to whether it is picked up on a regular basis (like trash or recycling), or if pick up is “intermittent” or one-time only (like a one-time donation of old office furniture).
Save the Dates: IMT and NASEO to host Webinars on Major 2018 IECC Code Change Proposals
In September, IMT and the National Association of State Energy Officials (NASEO) will kick off a five-part webinar series examining proposed changes to the 2018 International Energy Conservation Code (IECC). The webinars will take place every Thursday at 2 pm EDT starting September 15.
The first webinar in the series will focus on two important proposals related to multifamily buildings and agricultural lighting. Applying the provisions of the IECC to multifamily buildings has long been a source of confusion. Depending on the number of stories, the building may have to comply with the residential or commercial provisions, neither of which adequately address multifamily construction. Proposal CE-272 provides a solution to the longstanding confusion by creating a separate chapter in the IECC to address multifamily construction. The second proposal to be discussed is CE-200 which addresses agricultural lighting. In some states, agricultural lighting is one of the fastest growing energy end-uses. Proposal CE-200 will provide clarity around the use of lighting for plant growth and maintenance. Finally, the webinar will conclude with an overview of the IECC development process and upcoming key dates.
