In­nov­at­ive and en­ergy ef­fi­cient fire pre­ven­tion solu­tions for vent­il­a­tion sys­tems (Present­a­tion in Ger­man)

In­nov­at­ive fire safety solu­tions based on newly de­ve­loped con­cepts lead to re­duced in­vest­ment and main­ten­ance costs and im­proved en­ergy ef­fi­ciency in cent­ral vent­il­a­tion sys­tems in res­id­en­tial build­ings. These solu­tions have already been im­ple­men­ted in vari­ous pro­jects.

9:20 am

Kit­chen ex­haust sys­tems in Pass­ive House build­ings (Present­a­tion in Ger­man)

Ex­tract­or hoods have the task of re­du­cing air pol­lu­tion caused by cook­ing. The pa­per presents the res­ults of a re­search pro­ject on cook­er hoods in liv­ing kit­chens and de­rives re­com­mend­a­tions for pass­ive houses.

9:35 am

Re­duc­tion of Pass­ive House en­ergy de­mand us­ing mech­an­ic­al drink wa­ter hy­gi­en­iz­a­tion (Present­a­tion in Ger­man)

Eine weit­ere Re­duk­tion des En­er­gie­v­er­brauchs von Passivhäusern durch die Ab­sen­kung von Trink­warm­wasser­tem­per­at­uren set­zt die Sich­er­stel­lung von Trink­wasse­rhy­giene voraus. Die Ul­tra­fil­tra­tion bi­etet zu diesem Zweck neue Mög­lich­keiten, denn - richtig einge­set­zt - han­delt es sich um eine sichere Tech­nik für die Ver­hin­der­ung von un­kon­trol­li­er­tem Bak­ter­i­en­wach­stum. Der En­den­er­giebedarf für Wärmepumpen wird um rund ein Drit­tel re­duziert. Sie können somit na­hezu gan­zjährig den Wärmebedarf von Ge­bäuden deck­en.

He­at Pump Kom­bi Sys­tems - an over­view of re­cent de­ve­lop­ments not on­ly in Chi­na 

Highly ef­fi­cient vent­il­a­tion with heat & hu­mid­ity re­cov­ery is man­dat­ory in PH build­ings. Vent­il­a­tion sys­tems com­bined with a heat pump for heat­ing and cool­ing & de­hu­mid­i­fic­a­tion are the con­se­quent fur­ther de­vel­op­ment of the clas­sic 'com­pact unit' for Pass­ive Houses, which are a well ad­op­ted solu­tion for apart­ments in multi-fam­ily build­ings, too.

PH sui­ta­ble pre wall moun­ting sys­tems and ac­com­pa­nied ther­mal bridges in va­rious cli­ma­tes 

Thermal in­stall­a­tion bridges be­come great­er with thick­er in­su­la­tion. Thermal bridges of the bot­tom and top/side pro­file, un­covered by in­su­la­tion can be treated as equal. Par­tially cov­er­ing re­duces the thermal bridges by a factor of 1.8, com­plete cov­er­ing by a factor of 4.

10:40 am

Thermal bridge cal­cu­la­tions of bal­conies with two-di­men­sion­al re­place­ment ele­ments

This art­icle presents a meth­od for de­term­in­ing thermal bridge loss coef­fi­cients us­ing 2D sub­sti­tu­te mod­els for bal­cony con­nec­tions.
