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%.

Ahhh Yessssss.... Below Slab Insulation

The site structures crew is scrambling to finish the basement prep-work in time for the concrete truck that will be here at 7 AM tomorrow morning to pour the slab. They in the process of finishing up laying down the below slab insulation and are starting to tack the slab edge insulation into place. Once all of the insulation is in place, they are going to roll out a thick yellow vapor barrier and tape the seams which will create a neat and tightly bathtub for the concrete to be poured into.
