Holly Park - Phase I:
In phase I of the new Holly Park Housing Project in South Seattle, Ecotope
provided mechanical engineering services to troubleshoot installation
problems with the heating and ventilation systems. Ecotope rewrote equipment
and installation specifications to address potential backdrafting of gas fired
water heaters installed in the living space and
provided on-site testing and
diagnostics to evaluate the efficacy of those changes. Ecotope also developed
a commissioning protocol to ensure the safe and adequate operation of the HVAC
systems before turning the units over to the occupants.
Holly Park - Phase II:
Ecotope developed performance simulations to optimize energy efficiency in
these new row houses and compare life cycle costs of a range of insulation and
mechanical system options. Ecotope assisted in negotiations with Seattle
City Light to include this project in the Built Smart incentive program.
Ecotope developed an optimized energy conservation plan for the renovation of
the Beacon Tower housing project on Seattle's Beacon Hill. The energy
efficiency improvements include installation of new high performance windows
and the addition of 2 inches of exterior rigid foam insulation. Ecotope
developed documentation of energy savings and arranged for energy conservation
incentive payments from Seattle City Light to fund a significant fraction of
the improvements. To address indoor air quality concerns, Ecotope also
designed an inexpensive constant flow exhaust system to be retrofit into
existing chases and existing exhaust fan housings.
Olive Ridge is another Seattle Housing Authority building dating from the
1960s and located on Seattle's Capital Hill. Ecotope's work on the Olive
Ridge project was similar to the scope of work described above for Beacon
Tower. Ecotope's recommendations for work at Olive Ridge included replacement
of existing all electric central hot water and central ventilation systems
with new high efficiency gas equipment. Ecotope documented simple payback
periods of approximately 2-years based on fuel costs for these measures.
