PHPP 10 - The design tool for ro­bust­ness and fu­ture proof build­ings

In PHPP, the Pass­ive House stand­ard can be veri­fied us­ing stand­ard as­sump­tions for cli­mate or bound­ary con­di­tions. PHPP 10 will con­tain vari­ous ev­al­u­ation pos­sib­il­it­ies to also as­sess the per­form­ance of the build­ings un­der ex­treme situ­ations, like ex­treme cli­mate con­di­tions, for ex­ample due to cli­mate change, or ex­treme user be­ha­vi­or or build­ing use.

Ex­plor­a­tions in op­tim­iz­ing PHPP us­ing Grasshop­per

This pa­per show­cases com­pu­ta­tion­al design pro­cesses and tools Per­kins and Will Ar­chi­tects in Van­couver are ex­plor­ing in or­der to help early stage design on large scale pro­jects aim­ing for the Pass­ive House Stand­ard. The fu­ture am­bi­tion is to in­teg­rate PHPP in­to Design Space Con­struc­tion (DSC).

PHPP val­id­a­tion ac­cord­ing to ASHRAE 140

The ASHRAE stand­ard 140 is a test suite for build­ing sim­u­la­tion pro­grams that con­tains res­ults for the an­nu­al heat­ing and cool­ing de­mand for a ref­er­en­ce build­ing and 20 vari­ants. The PHPP suc­cess­fully passed this test.

Pro­ject-spe­cif­ic primary en­ergy re­quire­ments for pass­ive house cer­ti­fic­a­tion

This pa­per out­lines the meth­od­o­logy used to de­rive PE/PER tar­gets for large res­id­en­tial pro­jects ap­ply­ing for an ex­emp­tion. These are cal­cu­lated with a tool that is linked to a PHPP file, giv­ing a new PE and PER tar­get based on the sum of primary en­ergy re­quire­ments for in­di­vidu­al end-uses (such as light­ing, el­ev­at­ors, etc.).

Per­form­ance Mon­it­or­ing Ev­al­u­ation with PHPP 10

PHPP V10 will com­prise tools for sim­pli­fied per­form­ance ev­al­u­ation of build­ings. To this end the en­ergy bal­ance cal­cu­la­tions can be up­dated with the meas­ured bound­ary con­di­tions of the peri­od un­der con­sid­er­a­tion. Thus the build­ing’s op­er­a­tion can be fol­lowed up on a monthly basis. De­vi­ations from the de­signed per­form­ance are de­tec­ted early on and may be traced back and rec­ti­fied sys­tem­at­ic­ally.

A cal­cu­la­tion pro­ced­ure for heat losses caused by ven­ted drain pipes

Drain pipes in­side the thermal en­vel­ope that are ven­ted to the out­side cause ad­di­tion­al heat losses. The ex­ist­ing cal­cu­la­tion pro­ced­ure from PHPP 9 was up­dated to ac­count for the gradu­al warm­ing of air flow­ing through such pipes. Par­tic­u­larly for high-rise build­ings lower heat losses res­ult.
