PHPP

PHPP logo

PHPP calculates energy demand for buildings. It is compatible with international norms (ISO 13790) and well validated with dynamic simulation tools as well as with measured data. It is especially adapted to high-performance buildings and can be used to prove Passive House requirements. The planning package comprises many tools specifically useful for the design of high-performance buildings.

The Passive House Planning (Design) Package (PHPP) includes:

  • energy calculations (incl. R or U-values)
  • design of window specifications
  • design of the indoor air quality ventilation system
  • sizing of the heating load
  • sizing of the cooling load
  • forecasting for summer comfort
  • sizing of the heating and domestic hot water (DHW) systems
  • calculations of auxiliary electricity, primary energy requirements:
    • (circulation pumps, etc.), as well as projection of CO2 emissions
    • verifying calculation proofs of KfW and EnEV (Europe)
    • Climate Data Sheet: Climate regions may be selected from over 200 locations in
    • Europe and North America. User-defined data can also be used.
    • lot of tools useful in the design of passive houses, e.g. a calculation
    • tool to determine internal heat loads, data tables for primary energy factors
    • a comprehensive handbook, not only introducing PHPP use, but also
    • highlights crucial topics to be considered in Passive House design.

Validation/Testing

Basis for energy balance: ISO 13790. Tested with dynamic building simulation and with measured data in field project with some 1,000 apartments and additionally with non-residential buildings.

Expertise Required

Experience in building design or building energy consulting. PHPP training is recommended but not prerequisite. Use of manual (included).

Users

1,0000 users worldwide: 500 in the United States

Audience

Architects, engineers, energy consultants, scientists.

Input

Data are entered as numbers or chosen in menus. Needed: surface areas of thermal envelope, length of thermal bridges (optional), thermal characteristics of materials (thermal conductance) or building components (U-values), and of thermal bridges (optional); characteristics of ventilation system, efficiency of heat recovery, location of building. Characteristics of certified passive house building components are implemented.

Output

Pre-formatted documentations: Overview, energy balance, heating load, cooling load, summer comfort (percentage of overheating), ventilation, energy use/losses for heating system, primary energy demand.

Computer Platform

Windows PC with MS Office

Spreadsheet

Strengths

energy design and thermal comfort for high performance buildings, esp. passive houses

Weaknesses

Multizonal dynamic building simulation for buildings with large glazing areas (solar gains) and/or high need of control
