Lot Selection – Think about energy efficiency early including orientation
of your home on the lot, as well as the sun patterns across the sky in
both summer and winter. You can potentially reduce your energy costs
by up to 25% with passive heating through south facing windows and
proper placement of trees for wind blockage and summer shading.
Insulation – Look to insulate the foundation from the outside as well as
the inside if finishing off. Exterior walls need rigid board insulation on
the outside of the framing to obtain 100% coverage as well as wall
cavity insulation between the studs (r-20 to r-30 is recommended).
Insulation in the attic should be r-40 to r-50. Skylights and cathedral
and vaulted ceilings are more difficult insulation areas and should be
addressed by you with your designer and builder.
Vapor & Air Barriers – Vapor barriers prevent natural household moisture
from penetrating interior walls through electric light switches, outlets or
anything else that cuts into the drywall. Air barriers reduce air infiltration
through outside walls which can effect up to 40% of heating and cooling
costs. They are installed around the outside framing and rigid board
insulation and should be taped and sealed around windows, doors and
any exterior penetration.
Heating & Cooling – Energy efficient 95+% heating systems are
recommended for Wisconsin and Minnesota. Central air cooling systems
should be a minimum of 11 SEER rating. Meet with your heating contractor
at the building site. Also consider an air to air heat exchanger or similar
ventilation system to efficiently improve your indoor air quality.
Appliances & Lighting – Compare energy saving options when shopping
for appliances and lighting. Air tight recessed lighting is a great example
of an energy efficient lighting option. The extra initial investment for an
energy efficient appliance or lighting fixture can have multiple paybacks
over the life of the home.
