The model process developed would provide a progression of lessons learned which have been implemented by Sandia’s military customers.

A process of technology implementation over several housing development projects is recommended.

Each set of recommendations are ranked from very cost efficient approaches to conventional technology demonstrations to advancedtechnology demonstrations.

It is understood that additional funding will be needed for first cost of many technologies and energy efficient features.

Based on the existing HUD standard for cost per home & infrastructure cost allocation, many of these features may not be included in existing budgets.

• Programmable thermostatsR-38 attic insulationR-19 exterior insulation

• High-efficiency compact fluorescent lighting • Basic Clothes Line• White (or as close to white) roofing with 3-foot overhangs• High-efficiency refrigerator and Energy STAR rated appliances • Advanced solar control double glazed windows• Downsized SEER 15.0, variable speed, & 2-ton air conditioner

with field-verified cooling-coil airflow.• OR High efficiency swamp cooler, such as a Master COOL

evaporative unit• Solar hot-water systems• Photovoltaic (PV) systems

Specific features are recommended for energy use reduction:

12

These model homes should be implemented for energy use monitoring.

• One or two homes would feature the latest techniques recommended and the other would serve as the conventional home.• The goal would be how much energy could be saved without factoring in the cost of the energy efficiency features.• A close match of home owner and energy use between the zero energy home(s) and conventional home should be implemented.

The monitoring and analysis be used to demonstrate the use of these zero energy features to HUD homeowners & other constituents.

Along with other training provided, new homeowner training should include:

• energy conservation• peak energy management• energy use based on energy

interdependencies (mini-grid system which could include metering)

Information and training would provide a progression of lessons learned, not only for the homeowner, but for other constituencies.

DOE Renewable Energy Development on Tribal Lands

• Competitive solicitation depending on congressional appropriations

• Sandia technical assistance is provided to the awardees

USDA Rural Utility Service – Rural Business Development

• New grant to assist farmers, ranchers, & small rural businesses in

• buying renewable energy systems• making energy efficiency improvements

Sandia is interested in a long-range process of technology implementation for managing life-cycle cost to meet tribal housing needs

As part of the TEP team, Sandia’s activities and responsibilities include the following:• Program technical support• Project-specific technical support• Capacity building in Indian Country• Publications and outreach• Student Internship

Specific support as requested by the tribes (grantees):• Ramona Band of Cahuilla• Hualapai Nation• Navajo Nation• Hopi Nation• Laguna Pueblo

Tribal Energy Projects are showcased at the annual DOE TEP Project Review, November 17 – 20, 2008, Denver, CO
