78 Main St - Economic Blues

78 Main, Back, unchanged

Its been a little discouraging lately as we have had to put our 78 Main St renovation project on hold while we begin the loan process over again.

I’m sure that someone will provide just the right name for the economic turmoil we are all going through in the last 2 [...]

Low Temperature Water Heating

Solar Heating

If you have the opportunity to replace your heating system or if you are building a new house, you should consider a low temperature water-based system for the heating core. For instance, a radiant floor system or hydro-air system are both based on heating water to temperatures much lower than those required for [...]

Solar Collector

The solar collector we are building at my future house, 78 Main St, has been in place for a couple of weeks now, and we have been collecting temperature data. I’m hoping to have some “live” data at the website at some point in the future, but for now I have downloaded 8 [...]

Solar Collector - Hot Stuff!

Solar Collector

We are finally making progress again on the solar heating system at 78 Main St. After building the tank (Solar Storage), building the collector rack and trench to the basement, and building the heat exchanger (see pictures below), the next step was to get the two main loops pumping (see Solar Storage Tank, [...]

78 Main - Putting old and new together

It’s been a few weeks since my last update on the 78 Main St Renovation, and a lot has changed. Don Robert’s crew (Wayne, Aaron, and Bruce) have almost completed the framing of the new roof and walls within the old structure. David Dow (Double D Electric) has a permanent electrical connection to the house [...]

Historic Preservation – Embodied Energy

There is a new document that has recently been published to provide ideas and advice for energy efficient improvements for historic buildings. This document, “Energy Efficiency, Renewable Energy, and Historic Preservation” is available from the “Clean Air Cool Planet” (CA-CP) website.

First a note about CA-CP. This is a non-profit organization whose mission is “Finding [...]

78 Main - Solar Storage

Solar Thermal Storage

It took a while to get this going but we finally have a time-lapsed video of the building of the solar storage tank. This tank was designed by TSS (Thermal Storage Solutions) with installation help from Murphy Cell-Tech and Greenworks Solar.

I set up a webcam to get the time-lapsed photography [...]

78 Main – LEED-H meeting

LEED-H (Leadership in Energy and Environmental Design) is a certification program for residential homes to promote best practices in energy conservation, land and water use, air quality, and education in building construction. (Here is an earlier blog on LEED as it applies to 78 Main St, our renovation project).

This week I held a LEED-H [...]

Thermal Storage Tank, Part 2

Solar Storage tank

Unfortunately we had a problem with the webcam and didn’t get any time-lapse pictures of the second day of building the solar storage tank (see Thermal storage tank, part 1 from the first day). We did get some video footage and a few stills, see below.

The first day was the [...]

Solar heat

For our zero-energy building we are using the sun to provide ALL of the heat we will need throughout the winter. After months of discussion, engineering models of heat requirements, heat losses, heat storage and solar heat generation… the team came up with a system. There are three major ingredients:

Solar collector
Thermal storage [...]
