Apache

Software tool for thermal design & energy simulation related to buildings. In design mode, APACHE covers the calculation of heating, cooling and latent room loads, the sizing of room units, internal comfort analysis and codes/standards checks. In simulation mode, APACHE performs a dynamic thermal simulation using hourly weather data. Linked modules deal with the performance of HVAC plant and natural ventilation. APACHE is a component of the IES Virtual Environment, an integrated computing environment encompassing a wide range of tasks in building design.

Applications:

  • Thermal design (heating, cooling & latent load calculations)
  • Equipment sizing
  • Codes & standards checks
  • Dynamic building thermal performance analysis
  • Systems and controls performance
  • Energy use
Modules:
  • Geometrical modelling, building data input & visualisation
  • Management of data relating to materials, occupancy, plant operation and climate.
  • Shading analysis
  • Heat Gain calculations
  • Heat Loss calculations
  • Dynamic thermal simulation
  • Natural ventilation & indoor air quality analysis
  • HVAC system simulation
  • Results presentation & analysis

Expertise Required

2 days training is recommended for the basic modules, with additional courses available for specific applications. Available in UK and other countries by arrangement.

Users

Many throughout Europe.

Audience

mechanical building services engineers, local government, building managers & landlords, building design consultants, architects, and university research and teaching departments.

Input

Geometrical building data may be imported from a range of CAD systems via customised links or DXF files. Geometrical models may alternatively be entered using facilities within the Virtual Environment. Input of data relating to materials, occupancy, internal gains, climate, air movement and systems is managed via graphical interfaces and supported by extensive databases.

Output

APACHE presents a wide range of outputs in tabular and graphical form. Outputs may be exported in a variety of common formats.

Computer Platform

PC running Windows 95, 98 or NT (3.51 or higher). 100 MB Ram or paging disk. 100 MB disk space. CD-Rom drive.

Programming Language

Visual Basic, C++, Fortran 77

Strengths

Operates within an integrated computing environment covering a range of building analysis functions. Strong links with CAD. Undergoing rapid development, with continuing input from research and engineering practice. Supported by in-house expertise. Rigorous analysis and visualisation of shading and solar penetration. Flexible & versatile system HVAC and controls modelling. Integrated simulation of building and HVAC systems.

Weaknesses

Certain energy systems not covered currently, eg phase-change materials, roof ponds.
