RASLRES Energy in Wood Seminar John Dolan. Chartered Engineer BEng (Hons) M.Sc. Fire Eng H.Dip CEng MIEI Planning & Building Unit Tullamore www.energyineducation.ie.
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
