The building is super-insulated and equipped with a heat-recovery ventilation
system to control humidity and air quality.
Some of the sustainable building principles incorporated into the buildings design include using natural materials, natural ventilation, daylighting, heat-recovery ventilation
, infrastructure for future solar installations, rainwater catchment and micro-hydro electrical production, as well as brownfield restoration, open space and development density credits.
Three elements distinguish passive houses from typical houses: high levels of insulation, with walls up to 12 inches thick; a carefully sealed building envelope with minimal air leakage combined with efficient heat-recovery ventilation
for superior indoor air quality; and high-performance windows-typically triple-paned.
with Energy Star appliances, heat-recovery ventilation
, instantaneous solar domestic hot water, radiant floor heating and recycled materials; and a Victorian at 10 Circuit Ave.
The Wrexham study: method and control:Study involves 200 families where children aged five to 15 have had at least three prescriptions for asthma in the previous 12 months Half the families have a heat-recovery ventilation
unit, and improved central heating if required, installed from the outset and are then monitored for a year
However, it is important to bring in fresh air through mechanical means such as a heat-recovery ventilation
Three elements distinguish "passive house" structures from typical houses: high levels of insulation, with walls up to 18 inches thick; a carefully sealed building envelope with minimal air leakage combined with efficient heat-recovery ventilation
for superior indoor air quality; and ultra high-performance windows-typically triple-paned.
The winners were selected based on their project scores on the nationally recognized ENERGY STAR/HERS rating scale and used energy efficiency and renewable energy technologies such as super-insulation, passive & solar thermal designs, heat-recovery ventilation
, mini-split heat pump technology, super efficient windows, photovoltaic panels, and other energy-efficient technologies to achieve their goals.
