This document discusses the design of a passive house school building in a hot climate. It provides details on the building layout over three floors, U-values for walls, roof, floors, and windows. It also discusses the building envelope to total floor area ratio, glass to floor area ratio, PHPP calculations for heating and cooling loads, examples of classroom cooling load calculations, ventilation strategies including night ventilation, and floor plans for the first and second floors. The document is presented by a structural engineer and architect providing passive house and energy auditing expertise.

6. U values
• External walls U = 0,16 W/m2k
• Roof U = 0,14 W/m2k
• Floor U = 0,57 W/m2k
• Window Frame U = 0,8 W/m2k
• Glass U = 0,8 W/m2k

7. Heat loss form factor
• Building envelope / TFA = 1,8
• Glass area to TFA ratio 20%

8. PHPP

9. Heating

10. Cooling
• PHPP calculation

11. Real cooling load
• Classroom 72 m2
• 20 kids x 60 W = 1200 W
• 1200 W/ 72m2 = 16 W/m2

12. Ventilation
• Decentralized
