Ses­si­on 16: PHPP and oth­er tools

Wed­nes­day, 15 Sep­tem­ber 2021


PHPP is the cent­ral pass­ive house plan­ning tool. To­geth­er with oth­er tools, it en­ables for cost-ef­fect­ive and en­ergy-ef­fi­cient con­struc­tion to be re­li­ably planned. Ad­vanced co­or­din­a­tion, qual­ity as­sur­ance and in­tens­ive mon­it­or­ing of the real­ized pro­jects en­sure that the build­ings func­tion as 'planned'. The speak­ers will present the PHPP and oth­er valu­able 'di­git­al tools' and show by ex­ample how they are used.

Multi-pane win­dows in the PHPP

The new window classification system in PHPP 10 makes it much simpler and clearer to enter data for multi-pane windows. In turn, it is easier to optimise various window layouts. An example shows that it is possible to influence the heating demand by 2 kWh/(m²a).

Op­tim­isa­tion ap­proaches for af­ford­able and en­ergy-ef­fi­cient con­struc­tion


Many prac­tic­al ex­amples of highly-ef­fi­cient, af­ford­able solu­tions already ex­ist. However, much of this know­ledge re­mains in the hands of the de­sign­ers. Of­ten, there is no time to pass on this know­ledge. The LfU pub­lic­a­tion "Op­tim­isa­tion ap­proaches for af­ford­able and en­ergy-ef­fi­cient con­struc­tion" is a re­pos­it­ory of this know­ledge, mak­ing it avail­able for oth­ers to en­able all fu­ture build­ings to be highly ef­fi­cient.

En­ergy con­sult­ing with PHPP

En­ergy con­sult­ing can be well man­aged with the PHPP since com­plex build­ings can also be ev­al­u­ated. Op­tim­isa­tion is achieved quickly and clearly. The PHPP of­fers clear, re­li­able and com­par­able para­met­ers. Pass­ive House cer­ti­fic­a­tion is sub­sid­ised by BAFA and KfW = qual­ity as­sur­ance that helps to pre­vent lock-in ef­fects.

Af­for­da­ble hou­sing: Mit­i­ga­ting costs by en­han­ced PH co­or­di­na­ti­on

Pass­ive House provides health­i­er in­door en­vir­on­ments at lower op­er­a­tion­al costs, but the  chal­lenge lies in jus­ti­fy­ing the high­er up­front pro­ject cost.  A 50-unit so­cial hous­ing pro­ject  built in Ontario Canada, de­mon­strates how the es­cal­ated costs typ­ic­ally as­so­ci­ated with  these pro­jects might be mit­ig­ated.

Post-oc­cu­pan­cy mo­ni­to­ring: What to ob­ser­ve, how to se­lect equip­ment

Post-oc­cu­pancy mon­it­or­ing gives im­port­ant evid­en­ce of in-situ per­form­ance of Pass­ive House build­ings. Data ac­quis­i­tion must fit the char­ac­ter­ist­ics of a pro­ject, tem­por­al and spa­tial res­ol­u­tion chosen to a defined pur­pose. Meas­ur­ing un­cer­tainty shall be kept to an ac­cept­able level.

Pas­siv­haus stu­dent ac­com­mo­da­ti­on: les­sons learnt in the UK

Mon­it­or­ing of two Passivhaus gradu­ate ac­com­mod­a­tion build­ings shows some in­ter­est­ing fea­tures. Heat­ing load is con­sist­ent with Passivhaus tar­gets, and peak en­ergy load for the two build­ings is mod­est. Do­mest­ic hot wa­ter us­age pro­file is more evenly spread than of­ten as­sumed in MEP design.
