Renovation Timeline: April - August 2010
Armstrong House Project: Renovation
Renovation circa August 2010 – Siding and Roof Details Complete
April – August, 2010
We are pleased to report a busy spring and summer. Total volunteer hours on the project from late 2007 to the end of August 2010 now amount to over 1200 and that does not include the many volunteer hours put in by our GC, Ian Ashby, and volunteer experts. These hours do include over 40 Fox Lane and John Jay High School students earning community service credits, PRLC Board members and volunteers as well as other Pound Ridge and Bedford residents, often including their families, working on our Saturday morning supervised, volunteer work sessions. In early spring, the project site was experiencing pressing storm-water management issues – remember the structure has a rubble-stone foundation – which were effectively addressed with a French drain on the North and West sides of the house.
Gutters have been installed that direct all storm-water away from the structure. The gutter system has been configured in a way that will coordinate with the envisioned, future rainwater harvesting and distribution system. The results of these efforts have been measurable as the dry crawl space and foundation now lend themselves to a more durable and healthy structure and immediate environment.
One thousand square feet of radiant panels have been installed both upstairs on the walls and ceilings of the three bedrooms and downstairs on the floor in several of the main rooms including the kitchen, steward’s office and PRLC office. These rooms currently await the installation of three thousand feet of PEX radiant tubing. In review, this low temperature heating system is tied to a combination solar heating and hot water which will lower the environmental footprint of the residence. Rough framing of living spaces, floors and doorways are substantially completed and now allow for finishes and design in the upcoming months.
Additional spray foam insulation has been installed, further augmenting the performance of the building and the tightness of the structure’s thermal envelope. The innovative use of air spaces and low emissivity / high reflectivity foil wrap behind the future, finished ‘green’ drywall should provide a significant boost to the house’s ability to resist the transfer of heat energy. The 21st Century heating system will be configured to allow minute by minute, hour by hour and room by room zoning. The performance of this zoning system has been enhanced by the fact that interior walls have also been insulated with this reflective material plus air space. (It is envisioned that all environmentally sensitive building – whether residential or commercial in the future – will provide for interior wall insulation and room by room zoning). This practice in the Armstrong House will further reduce fossil fuel consumption and address the comfort needs of the home’s residents.
All the carpentry necessary to prep the exterior façade including the recycled siding and soffit detail, is substantially complete and all siding and trim have been prepped for priming. A team of volunteer painters are currently working their way around the house on both the first and second floors.
Pending autumn work includes the installation of the radiant heating system PEX tubing, conduction plates, finish wood floors and sub-flooring for the linoleum flooring. Domestic hot-water, cold-water, and rain-water manifold distribution system will also be installed in the house in the upcoming months as well as the mechanicals associated with the combination solar heating and hot water system. (See the most recent energy systems concept paper dated June 2010).
Throughout the renovation, the project site has been managed with an eye to reducing waste that ends up in a landfill and to recycle and re-use as much construction material and components as possible.
