Commissioning: The first logic step for
realizing high comfort buildings!
Passiefhuis-Platform vzwDe REFLEX voor energiebewust bouwen
What is a “high comfort building”?
• Comfortable feeling independent the outside weather conditions
• Influencing parameters:– Surface temperatures– Air temperature– Air velocity– Air humidity– Air quality– Degree of activity– Clothing
Necessity of a well-defined definition
Passiefhuis-Platform vzwDe REFLEX voor energiebewust bouwen
• BASE CONDITIONS– Heating demand ≤ 15 kWh/m².year– Air tightness n50-value ≤ 0,6 /h– Frequency of overheating ≤ 10% above 25°C
• SECONDARY CONDITIONS – U-values (walls, floors, roofs) ≤ 0,15W/m².K– U-values windows ≤ 0,80W/m².K– U-values glass ≤ 0,80W/m².K– Efficiency of heat exchanger ventilation ≥ 75%– Efficiency fans (SPF) ≤ 0,45W/(m³/h)– Thermal bridge free construction Ψ ≤ 0,01W/m.K
Passive house concept is currently the only well-defined standard!
Build-in ≤ 0,85W/m².K
