Problem: To design a house that is sustainable economically, environmentally, and socially. Solution: A one family house (1800 square feet), located in Boulder, Colorado with two floors and a basement. Systems Used: Water: Filtered and Chlorinated Ground Water Waste Water: Aerobic Septic Tank Energy: Heating and Cooling : Ground Source Heat Pump Water Heating: Photovoltaics SUMMARY

INTRODUCTION HOME AND SYSTEM SPECIFICATIONS

URBAN SETTING LOCATION: BOULDER, COLORADO

TOWN ON THE OUTSKIRTS OF BOULDER, COLORADO COMMUNITY

ANALYSIS THE DESIGN PROCESS

BUILDING MATERIALS Specifications As ‘tight’ as possible Sustainable Cost effective Withstanding of all weather Ideas 1.Adobe 2.Rammed Earth 3.Straw Bale 4.Recycled Newspaper

BUILDING MATERIALS CRITERIA -Cost -Instillation -Longevity -Easy to Maintain -Durable Straw Bale Aesthetically Pleasing Easiest to Install Most Efficient in Heating and Cooling Durable

STRAW BALE BUILDING MATERIALS

ROOM LAYOUT Specifications Facilitate mobility throughout the house Energy Efficient Ideas 1.Closed 2.Open

ROOM LAYOUT CRITERIA -Easy to get around -Energy Efficient Open Layout Less building materials More energy efficient Don’t have to heat up each room separately

OPEN ROOM LAYOUT More energy efficient

WATER SYSTEM Specifications Make water more acceptable for desired end-use Drinking Appliances Washer/Dryer Toilet Sink Shower/Bath Ideas Disinfectant 1.Chlorination 2.Ozonation 3.Ultraviolet Radiation Source 1.Surface Water 2.Ground Water Systems 1.Reverse Osmosis 2.Filtration and Disinfection 3.Boiling 4.Bottled Water 5.Water Softener

WATER SYSTEM CRITERIA -Cost -Effectiveness -Ease of Use -Availability -Maintenance Chlorination and Filtration Most inexpensive One of the most effective methods Does not require electricity to run Little maintenance necessary

CHLORINATED AND FILTERED SURFACE WATER WATER TREATMENT

WASTE WATER SYSTEM Specifications Removal of Black/Grey Water Cost Effective Highly Efficient Easy Maintenance Ideas 1.Anaerobic Septic Tank 2.High Efficiency Anaerobic Septic Tank 3.Aerobic Septic Tank 4.Sand Filter

WASTE WATER SYSTEM CRITERIA - Short term cost - Long term cost - Efficiency - Maintenance - Ease of use - Durability Cost: ≈$7,000 Sprinkler system Needs less space than other tanks Aerobic Septic System

AEROBIC SEPTIC TANK WASTE WATER

APPLIANCES 20 60W Fluorescent Light Bulbs 10 25W Fluorescent Light Bulbs 2 Television sets Dishwasher Washer/Dryer Fridge/Freezer Water Heater Low-flow Shower Heads (1.5gpm), Temp F Run Time: 45 minutes Thermostat Average Temperature 70 0 Heat Exchanger in vents

ALTERNATIVE ENERGY Specifications Ability to produce energy As close to zero- energy as possible Self-sustaining Potentially selling back to the grid Ideas 1.Solar Water Heating Panels 2.Wind Energy 3.Photovoltaics

ALTERNATIVE ENERGY CRITERIA -Cost -Durability -Return on Investment -Ease of Use -Transportation -Installation Photovoltaics Cheapest Option Long Term Profit Minimal Investment Upfront Easier Installation

CALCULATIONS Energy Audit13000 kWh/yearCost from grid$0.092/kWH Since there are 8760 hours in a standard yearCost per year$1, Power Needed1.5kWSystem Durability20 years Sunshine in CO6hrNet profit$11,328 Power in this time6kWNet yearly profit$630 Spec600 sq.ft. South facing on roof520 sq. ft. Mounting on roof allows us to expad that area Cost of inverter+PV$3/W Cost of Power18, State Subsidy(3,600.00) Federal Subsidy(4,200.00) Total Cost10,200.00

PHOTOVOLTAICS ENERGY GENERATION

ENERGY: HEATING AND COOLING Specifications Balance heat loss in the winter Counter the heat gain in the summer Efficiency Easy to Maintain Ideas 1.Ground Source Heat Pump 2.Air Source Heat Pump 3.Woodstove/Air Conditioner

ENERGY: HEATING AND COOLING CRITERIA -Cost -Efficiency -Instillation -Maintenance Ground Source Heat Pump Provides heating and cooling in one Less energy=less pollution Very Efficient

GROUND SOURCE HEAT PUMP ENERGY-HEATING AND COOLING
