The Sustainable Living Center Winter 2011 “Fostering Sustainable Habits”

Outline The thermal audit – What can we do to improve performance Solar hot water system Water, energy and steam use SLC Projects: – Worm Compost – Laundry Drying – Vegan Food Workshops

The Thermal Audit The Blower Door: blows the hot air out and sucks cold air in thru the holes in the building envelope. Below: reading the pressure

The Thermal Camera

The Electric Meter

Thermal Audit Recommendations Close door to basement to stop leaks Insulate holes above windows in basement Make sure all storm windows are closed – Use plastic over windows as needed Insulate some pipes in basement – Note: steam pipes need special high-temp insulation Insulate above ground foundation

The Solar Hot Water System

System Performance

The Meters: Hot water and Steam

The Steam Meter Lots of work has been happening in mechanical room

Domestic Water Use Jan 1 st 2011-today (Feb ): gallons – 58 days (jan1st – 2/27) – 17 people 10.8 gallons person per day ~ 11 gallons/person/day

Electricity Use since Jan. 1 st 2011

Weekly Electricity Use

Daily Electricity Use

Electricity Consumption Electricity: Jan 1-today (2/27/11) at 4:15pm – kWh 33 kWh per day 1.94 kWh per person per day

Steam Consumption in Pounds Winter Term usage: Jan 2011: pounds and Feb 2011= pounds – Use 945 BTU per pound (note this changes with temp. and pressure) SLC used BTU – Assume heating plant is 75% efficient BTU per gallon of #6 oil*.75 = BTU SLC used ~501 gallons of #6 fuel oil for January and February 2011 – The SLC uses 0.5 gallons per person per day

SLC Student Projects Friday Dessert and Documentary The food coop – Bunten Farmhouse coop Milk, cheese, bread and ice cream Worm Composting Dryer Free: Laundry drying Students Fighting Hunger Workshops – Yogurt making – Vegan pizza

Worm Compost

Dryer Free Laundry

Potential Outside Laundry Drying Location

Vegan Pizza Making Workshop Vegan pizza making workshop and documentary Friday Jan hosted by Dartmouth Animal Welfare Group and the Upper Valley Vegan Meet-up. Peaceable Kingdom
