In response to a quickly transforming real estate market, the Newport Restoration Foundation (NRF) has launched a multi-phase energy efficiency project to collect data to improve the sustainability of historic residential buildings. NRF is investigating non-intrusive interventions that are sensitive to historic fabric while also improving energy efficiency in historic structures. The first project site will be 38 Green Street, a c.1730 Newport cottage-style house in the Newport Historic Hill District. The project will be both a case study of the energy efficiency of historic structures and a prototype for solutions that will be beneficial for other homeowners seeking ways to reduce energy consumption and increase livability in their own historic houses.

Frankie Vagnone, President of the Newport Restoration Foundation stated, “One of the fundamental preservation goals of NRF has always been livability. Our founder, Doris Duke, did not simply want perfectly restored, doll house-like historic buildings. She wanted them to be lived in and enjoyed as authentic, contributing elements in the urban landscape. We are honoring her philanthropy by pushing to make historic homes more comfortable and energy efficient”.

38 Green Street was purchased and restored by NRF in 1983 and has remained an active rental in NRF’s tenant-stewardship program. 38 Green Street is typical of many historic houses in Newport, with 1,200 square feet of living space, two floors, and a basement. Just like 38 Green Street, many of Newport’s older houses are unable to meet modern building efficiency standards. In response, many historic homeowners believe their houses cannot become efficient without removing and replacing historic fabric. Historic windows, siding, and doors are often the first elements of a house replaced with modern, ill-suited alternatives to reduce air changes and lower utility bills. Too often, these new features are incompatible with older house construction techniques, fail earlier than the older components they replaced, and reduce the character and appeal of both the interior and exterior of important historic homes.

In Newport, the unique construction techniques of its intact 18th-and 19th-century buildings often lead to energy inefficiencies. Plank construction consists of vertical sheathing boards with clapboards or shingles nailed to the exterior and lath and plaster applied directly to the interior, leaving no wall void. Conventional techniques of adding insulation to the interior or exterior could greatly alter the historic appearance of a property and cause vapor barrier concerns. “Many Newport buildings are of plank construction, and typical interior insulation fixes aren’t always an option,” says Margaret Back, Preservation Projects Manager at NRF. “This study will explore new, innovative ways to both make a historic property more efficient while retaining its historic materials and character.”

NRF has awarded the project to Building Conservation Associates, Inc. (BCA) of Newton Center, MA, a national architectural conservation firm with experience in energy efficiency studies. The project begins in 2024 with a comprehensive energy audit of the study site and research of comparable buildings in Newport. With an understanding of the building and baseline energy data, BCA will propose a series of efficiency retrofits and alterations that consider new technologies and materials, protection of historic fabric, and socially progressive preservation concepts.

NRF will provide real-time updates on the process so that both local and broader historic preservation communities can benefit from the ongoing process of discovery. A successful final product understands there is no “one size fits all” approach but takes a balanced view of improving an energy baseline while sustaining identified historic materials and character.

We understand that as each historic property is unique, there is no “one size fits all” answer for improving energy efficiency. However, we are aiming to create and implement scalable guidelines that we and other historic property owners can implement to improve historic buildings while retaining the historic fabric and character.

 

 

Strawbery Banke Museum, the City of Portsmouth, New Hampshire Planning Department and DPW Water | Wastewater | Stormwater Division, the University of New Hampshire (UNH) Earth Systems Research Center, and the Newport Restoration Foundation (NRF) are proud to co-host Keeping History Above Water® (KHAW) in Portsmouth, New Hampshire on May 7-9, 2023 at the AC Hotel Portsmouth Downtown/Waterfront.

KHAW® was founded in 2016 by NRF to foster a national conversation focused on the increasing and varied risks posed by sea level rise to historic coastal communities. KHAW programs, conferences, and workshops focus on protecting historic buildings, landscapes, and neighborhoods from the increasing threat of inundation.

As one of the oldest port cities in the nation, Portsmouth has faced sea-borne challenges from the start. As its most historic neighborhoods and treasures find themselves increasingly threatened by sea level rise, more frequent flooding, and groundwater infiltration, the City, UNH, and Strawbery Banke Museum, a living history museum at the heart of that neighborhood – and at the lowest point in the city – are working together to collect data and test solutions.

KHAW: Portsmouth is designed to showcase the latest flood and climate data, discuss strategies and identify best practices, and bring new information to the dialogues on the impacts of sea level rise, recurrent flooding and climate change on historic resources begun at previous conferences. We seek to foster the discussion of how communities can adapt research data into actionable solutions and anticipate attracting presenters and attendees especially from the New England states.

Preservationists, public historians, museum professionals, archaeologists, planners, floodplain managers, engineers, architects, landscape architects, artists, conservationists, environmental justice advocates, government officials, property owners, resilience officers and other stakeholders are invited to submit session proposals.

Sessions may be individual presentations, panel discussions, or workshops, and will generally be scheduled to last 30 or 60 minutes. Please indicate in your proposal the length of your session.

We welcome proposals related to the theme “Water Has a Memory: Preserving Historic Port Cities from Sea Level Rise.” We specifically encourage sessions that:

  • Highlight adaptation, mitigation, and resilience strategies currently being employed to protect historic resources around New England
  • Showcase projects that encourage public outreach/education and/or attempt to effect positive change in the greater community
  • Discuss municipal concerns and processes for engaging stakeholders: residents, businesses, nonprofits and City government
  • Offer models for collaborative, “real world” solutions
  • Provide insights on resources and best management practices that foster affordable and equitable answers to sea level rise impacts on private and public assets.

Proposals should be submitted as Microsoft Word documents to sseacord@cityofportsmouth.com by 5 p.m. on December 10, 2022. Visit historyabovewater.org/2023-portsmouth for more information. Submit questions to the conference organizer, Stephanie Seacord at sseacord@CityofPortsmouth.com. Sessions will be selected by early January 2023.

“Doris Duke did a wonderful thing fifty-some years ago when she preserved these Colonial houses,” he said. “Here we are 50 years later, and it is our responsibility to ensure that the work she did is not lost. To do for Newport a second time what she did for Newport the first time — to save these Colonial properties.” – Mark Thompson, Executive Director, Newport Restoration Foundation
