RASLRES Energy in Wood Seminar

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,

27 professional / technical staff

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

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 operation projects

• acknowledged by national &

international energy awards

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
