Six main approaches contribute to the overall effective and efficient use of energy in the Hanover House. They are: superinsulation, high-performance windows and doors, airtight construction, mechanical ventilation, active solar space heating, and lighting and appliance efficiency.
The Hanover House shines in its energy performance. During the first three years of operation, the total annual energy consumption for the house ranged from 4,250 to 5,560 kWh, and the total annual thermal energy consumption ranged from 1,200 to 2,240 kWh.
The Hanover House uses 1.1 Btu/ft2 DD-F (6.2 Wh/m2 DD-C) for all energy, and 0.40 Btu/ft2 DD-F (2.3 Wh/m2 DD-C) for combined heating and water heating. Although heating and water heating are not broken out (because both are done with the 5 kW water heater element), Rosenbaum estimates that heating accounts for no more than 75% of this, or 0.25 to 0.30 Btu/ft2 DD-F (1.4 to 1.7 Wh/m2 DD-C). During the three years for which we have energy consumption data, the space heating cost thus ranged from $100 to $190 per year—with electric resistance heat! |
| 选址和节水方案: |
The Hanover House was built for durability; thanks to careful selection of materials and attention to moisture and airflow, the house should be very durable.
Very little lumber from large-diameter trees was used; most framing members larger than 2x4s were trusses, I-joists, or Parallams(R). Oriented strand board was used for sheathing and subfloors.
The flooring is hardwood, tile, and natural linoleum. Counters are granite. Only water-based finishes were used. |
| 室内环境品质: |
Though separate graywater treatment is not permitted in Hanover at this time, designer Marc Rosenbaum chose to plumb the house so that graywater (wastewater from the showers, bathroom sinks, and washing machine) could be collected separately and used for landscape irrigation or other water needs if regulations change. |
| 材料选择: |
The indoor environmental features of the Hanover House are: uniform temperatures throughout the house (even next to the windows), lots of daylight, operable windows, low- or zero-formaldehyde wood composites (floors are wood, tile, and natural linoleum; counters are granite; only water-based finishes were used), no combustion of wood or fossil fuels on site, continuous fresh air, and a radon-mitigation system. |
