Ashworth Cottages Greenest Home in Washington State with LEED Platinum Certification
Pryde + Johnson, a leading developer
of high quality green and sustainable homes, has received the highest award
for Leadership in Energy and Environmental Design (LEED) for its Ashworth
Cottages model home by achieving Platinum Certification by the US Green
Building Council (USGBC), making it the first home in Washington State to
attain this honor, setting a new standard for building green and
sustainable homes and communities.
Ashworth Cottages is one of only seven homes in the nation to achieve
LEED Platinum Certification by the
USGBC -- the highest level certification
offered. LEED for homes is the nationally accepted benchmark for the design
and construction of high performance green buildings. Developed and
sponsored by the USGBC, LEED is a rigorous rating system that establishes a
common standard of measurement for what constitutes green building. All
LEED certified homes are third party inspected and performance tested
providing validation of the homes green features.
A catalyst for change, Pryde + Johnson is leading the way with Ashworth
Cottages by demonstrating what is possible to achieve when building to
highest standards for energy savings and environmental design. Ashworth
Cottages is a model for renewing urban spaces and building sustainable,
environmentally friendly communities.
Ashworth Cottages homes offer a complete package of environmental and
sustainable features that benefit the homeowner, the community and the
environment. "The Pryde + Johnson design team took an integrated approach
to building Ashworth Cottages targeting the highest green standards and
LEED certification from the onset," said Curt Pryde, principal,
Pryde +
Johnson. Ashworth Cottages community of homes is designed to reflect and
compliment the architecture and heritage of the surrounding neighborhood
and to build community. Among the homes high performance environmental
features are its:
- Innovative, Custom Designed Heat Recovery Ventilation System - A
dedicated system connecting the homes indoor/outdoor air exchange and
high level air filter system with the hot water system providing heat,
air conditioning and 100% air exchange while filtering out more than
95% of airborne particles providing a healthier home and energy savings
estimated at $300 per year.
- On-demand hot water system - Instant hot water is available at the push
of a button saving both energy and water.
- Energy Efficient - Ashworth Cottages use as much as 50% less energy
than similar sized homes built to state code. The homes are BUILT SMART
and ENERGYSTAR certified, guaranteeing that the homes will be more
comfortable, save money and conserve resources. Lighting fixtures alone
save more than 85,000 kWh annually and contribute 51 metric tons of CO2
Avoidance which is the equivalent of removing 34 vehicles from the road
every year.
- Smaller Homes Minimize the Environmental Footprint - The cottage homes
optimize the functional use of space and provide comfort with less
square footage. The community of 20 homes exists in the space of what
would traditionally be six residential homes without looking or feeling
like it.
- Located in the City Revitalizing Urban Space - The new community of
single family homes is located in Seattle, on a previously developed
site, on the edge of Green Lake's commercial core and park providing
easy access to businesses and recreation.
- Efficient Water Use - The homes use only high efficiency fixtures and
dual-flush toilets, which are calculated to reduce net water usage by
40%. A rainwater cistern provides all the water necessary for
landscaped areas that feature native and drought tolerant plants
thereby eliminating the need for municipal water for irrigation saving
natural resources and the homeowner's money.
- Substantial Use of Locally Sourced Materials - All paints, windows,
counter tops, brick masonry and framing materials are locally sourced
which results in reduced transportation impacts and supports the local
economy.
- Recycling - More than 90% of construction waste from the project has
been recycled, diverting it out of landfills, as is the standard
practice for all Pryde + Johnson projects. Brick and terra cotta
building materials from the structure previously on the site have been
salvaged and reclaimed for use in the landscape features. Structural
timbers from the previous structure have been reused in the cottages
common building. Recycled content materials used in the home include
custom concrete countertops with recycled glass, tiles, carpets, and
Trex decking is used for backyard decks.
- Indoor Air Quality - Zero-Voc interior paint is used; reducing the
amount of VOC's found inside and significantly improving indoor air
quality. Vehicle emissions protection is ensured with carbon monoxide
detectors installed in rooms above the garages and living spaces are
tightly sealed. Garages have exhaust fans with timers linked to the
garage door, programmed to stay running until exhaust is gone.
Formaldehyde-free interior doors and millwork eliminate formaldehyde
exposure altogether.
