New Hampshire Home May-June 2023 - 80

GREEN DESIGN: ENERGY-EFFICIENT HOME
WINNER: Beaver Lodge Lookout * Kaplan Thompson Architects * Portland, Maine * (207) 842-2888 * kaplanthompson.com
As recent empty-nesters, the clients were ready to
downsize with a glassy new residence on 3.2 acres
of picturesque marshland. The sweeping views
came with the requirement for significant setbacks
from the wetlands, leaving a small buildable area
just down from the street. The siting naturally
accommodated the clients' primary goals of netzero
performance and preserving the beauty of
the property. The primary living spaces follow an
east-west axis, granting southern exposure to the
long, marsh-facing façade. Floor-to-ceiling tilt-turn
windows unfold along the back elevation, letting
occupants soak in the scenery while their home
soaks up passive solar heat. Triple-glazed windows
and doors mitigate heat loss during the winter,
while an exterior aluminum trellis provides just
enough shade to prevent overheating in warmer
months. Non-toxic cellulose super-insulates both
of the home's wall assemblies. The interior climate
is moderated by multiple air source heat pumps,
two energy-recovery ventilators, and electric radiant
heat in heavily trafficked zones. Despite the energy
demands of its advanced HVAC system, a 14 KW
rooftop photovoltaic array generates a surplus of
electricity for the home. As their neighbors are
subject to significant increases in utility costs, our
clients are receiving monthly paybacks from their
electric company.
What the judges said: True love! We applaud
the commitment to the environment while still
celebrating great design that connects to this
family's love of nature.
GREEN DESIGN: NET-ZERO READY HOME
WINNER: Downtown Net-Zero Ready Residence * Winter Holben Architecture + Design * Kittery, Maine * (207) 994-3104 * winterholben.com
Despite some unique challenges, the client's
ambitious vision of a contemporary, sustainable
new residence in a densely populated downtown
Portsmouth neighborhood was brought to life.
The gabled structure, a nod to the neighborhood's
aesthetic, is modernized with high contrasting
color, shape and scale. Horizontal, white, lowmaintenance
siding joins wide, black, vertical
paneling and trim-all with extended warranties to
guarantee long life spans. Everything is powered
by on-site renewable energy, generated by a roofmounted
solar array and concealed components.
A vehicle charging station sits smartly in the
driveway. Complementing the environmentally
conscious exterior, a healthy, attractive interior
environment is achieved using high-performance
ventilation and eco-friendly materials. The efficient,
highly insulated envelope reduces heating costs
in the winter and cooling in the summer. A glasswindowed
stairwell, contemporary minimalistic
metalwork and other creative solutions create a
pleasing flow, open living and lots of natural

light. Outside, multilevel decks and a spacious
patio further enhance the home. The solar panels,
a pandemic-related replacement to more powerful
panels the team originally chose, generate just
under the required amount to make it fully
net-zero.
What the judges said: This project demonstrates
an immense respect for the neighborhood and
proves that great design can be achieved responsibly
and on a budget. It stands as a positive role
model for all.
