The atypical Mathew solar house at Coos Bay, Oregon

摘要: Abstract The Mathew solar house in Coos Bay, Oregon is an atypical several respects: Its location on the cloudy winter coast. combination of near-vertical collector and near-horizontal reflector. unusually large 8,000 gallon storage tank. near-identical collectors; one house, other freestanding. This paper assesses contributions made by energy space heating. apparent contribution approached from two directions: 1. (1) Calculation “Assumed Solar” Energy— House heat loss calculated known contributed electricity, people direct gain through windows subtracted; remainder assumed stored energy. 2. (2) “Measured Stored utilized measuring provided collectors, then adjusting for deposited or withdrawn during each month, losses to ground storage. monthly “assumed solar” compared “measured solar”, reasons differences are discussed. distribution complete needs (24,230 kWh season) is: 52%: 22%: Direct windows. 13%: Electric appliances lights. 9%: 4%: Heat occupants' metabolism. When net heating requirement considered less windows, lights appliances, people) this 14,802 kWh, termed “space heating” requirement. distributed: 85% 15% resistance units. measured collector/storage tank contributions, when with those calculation, indicate close agreement over 8-month season, but wide variations some months. Some variation can be attributed uncertainties measurements; it does a role earth facing uninsulated
