ADDITIONAL INFORMATION

Note solar thermal unit on the roof (detail in next illustration below).

One of 50 PUSH owned properties in a 25 block radius PUSH Green Development Zone centering on Massachusetts Avenue.

About half of the properties are existing houses that are in need of rehabilitation; the other half are vacant lots.  Building new housing is not part of the project.  The main source of funding is a 2005 Green Development HUD grant.

Cement composite siding. Superinsulated.  See text below.



Local 17 dug a 100’ L x 6’ W x 6’ D trench in the vacant lot next door. At six feet deep we are below the frost line where the ground temperature is a constant 50-55 degrees.

We buried 700’ of plastic piping at the bottom of the trench with two supply and return lines connected to a series of pumps, controls, and mechanical equipment in the basement.

The key piece of mechanical equipment is the heat pump - a water to water heat exchanger that utilizes energy efficient compressor technology to extract heat from an anti-freeze solution that cycles through the ground loops and then super heats water that gets distributed through a network of underfloor radiant tubing that runs beneath each floor of the house.

Basic information:
This is a demonstration project, not a model home. Under current market conditions and government subsidy programs, it is not possible to replicate and scale-up the net zero design concept within the PUSH Green Development Zone.

With this project PUSH attempted to demonstrate two things:

1. Cutting edge renewable energy and energy efficiency technologies and installation techniques, including solar thermal (or solar hot water), solar photovoltaic, geothermal heating, and super insulation.
 
2. The potential of affordable housing development projects to drive community-controlled economic development and job creation.

Features of the project:
For 10 months the net-zero house hosted two crews of 10 YouthBuild program trainees. The YouthBuild members worked alongside tradespeople and union apprentices to complete the rough framing, plumbing, and electrical work in the house.

A couple YouthBuild members transitioned into full-time work on PUSH’s 11-unit green affordable housing development project on Massachusetts Ave. where they receive living wages as full-time employees of Lamparelli Construction Company. Another member is now a 2nd year plumbing apprentice with Local 22 Plumbers and Steamfitters.

30+ trainees from the Outsource Center, a grassroots work readiness and construction training organization based on the East Side, joined the project over the course of the final 10 months and completed much of the insulation and finish work in the house. They were led on the job by a veteran union carpenter. Most of the Outsource trainees have since gone on to work at the renovation of the Lafayette Hotel.
