Beddington Zero Energy Development, commonly
known as BedZED. It will accommodate 420 pupils
aged 5-11.

development was the first large-scale development
in the UK designed to be carbon neutral. A decade
later, Hackbridge Primary School is a new showcase
for the latest sustainable technologies and advanced
building systems an exemplar that will form part of
the educational experience for thousands of children
in years to come.

energy consumption through very high insulation
levels, low air permeability and well considered
junctions to minimize thermal bridging. These
efficiencies reduce the size of renewable energy
In this instance, Elementa proposes to achieve this
through an array of building-integrated high-efficiency
solar photovoltaic panels and a reverse-cycle ground
source heat pump system. The potential for inter-
seasonal thermal storage to boost the system's
coefficient of performance is being evaluated. No off
site renewables are required.
use. Instead, it will use induction hobs to minimize
combustion flue products from the site. The building
will have a single high-efficiency central air handling
unit to provide mechanical ventilation to classrooms
in winter. In mid-season, the windows are openable
by staff for controlled ventilation. In peak summer, to
provide resilience against future climate change, the
mechanical system can operate in conjunction with
cooling from the reverse-cycle heat pump, whose
efficiency is boosted by the inter-seasonal heat storage
system.
