planning and building unit

  • based in Tullamore
  • sub units – property management & site

acquisitions, schools capital appraisals, construction & developing areas , forward planning and professional & technical

  • headed by Seán O Foghlu, Assistant Sec Gen
  • 141 staff – 9 managers, 105 admin,

energy in school design

  • evolved from energy programme DART

(Design, Awareness, Research & Technology)

  • informed by building unit professional &

technical staff & external partnerships

  • driven by technical guidance documents
slide-4
SLIDE 4

energy in school design

  • updated by continued energy research &

development

  • disseminated by internal / external

publications, conferences & annual report

  • supported by SEAI and cross border co
  • peration projects
  • acknowledged by national &

international energy awards

slide-5

issues particular to schools

  • hours of operation
  • schools needs: not same as domestic

market needs

  • technical ability on site
  • energy is not core function
  • solutions must be robust
