A Brief History

The project entails repairing the building at 335 Maplewood Ave in a manner that meets both preservation and sustainability goals. The building is the new location for Petersen Engineering, a firm that has been located in Portsmouth since 1992, and specializes in sustainable building engineering. We intend for this project to showcase techniques & materials that promote both preservation and sustainability and intend to share all aspects of the project locally and regionally through open houses, presentations, industry tradeshows, case studies and publications. We foresee this project being a valuable educational tool to demonstrate that preservation goals need not be compromised by sustainability goals. We have teamed with Bruss Construction who we know from past collaborations has exceptional experience and expertise on projects with the dual goal of preservation and sustainability.

The project received approval by the Historic District Commission on January 6, 2010 with construction scheduled to begin early February 2010.

The projected peak heat loss reduction is 85%.

Northwest St. Sill Replacement


Picture: Closing up the Maplewood Ave facade on Friday.





The black membrane seen is a capillary break (Ice & Water Shield). This will prevent any water that wicks up the foundation from contacting the sill. Most of the sill on the Northwest St. was only rotten on the bottom. Hmm...maybe it was a result of capillary action?
