Software Tools

Ramp up your design capability and productivity quickly using the:

Intuitive graphical user interface and a visual directory tree to simplify inputs and give you direct access to specific ceiling, wall, floor, foundation and HVAC system screens – it also covers electrical base loads and hot water systems
Projections of space heating load and monthly and yearly energy requirements, taking into account utilized solar and internal gains
Full analysis capability in Imperial, U.S., or Metric (SI) units; and includes climate data from hundreds of Canadian and U.S. cities, as well as selected centres outside North America
Instant access to context-sensitive pop-up windows to define and explain each field, plus a full set of built-in help files to give you all the details
Technical reports for full-house, selective house (customized) and multiple house technical assessments, including site-specific data, fuel-cost data and detailed monthly tables

Model:

Electric, natural gas, oil, propane and wood space heating systems and domestic hot water (DHW) systems
Space heating and DHW systems from conventional to high-efficiency condensing systems
Air, ground and water source heat pumps
Central air conditioning systems with conventional or economizer controls
Primary and secondary DHW systems, including solar DHW
Inputs of steady state or seasonal efficiencies for heating and cooling equipment
Solar gain through windows in 8 cardinal directions
Tilted windows, including skylights
Overhangs, taking into account the hourly position of the sun with respect to each window and overhang on a typical day each month
Various levels of thermal mass
Slab-on-grade, crawl space (open, ventilated or closed), basement and walkout foundations, taking into account: dimensions; resistance and placement of insulation; soil conductivity; water table depth; and weather/climate
A house as 3 zones - attic, main floor and foundation - taking into account the heat transfer between zones

Calculate:

The seasonal efficiency, based on the characteristics of the specified house, for:
space heating systems, including part load curves and on and off cycling; and hot water tanks, including hot water load, standby losses and location
Heating and cooling loads on the basis of house design
Design heat loss rates for space heating system sizing
Fuel consumption and costs
Effective R-value of envelope components, including thermal bridging of the framing materials
Effective R-values of attic ceiling structures, taking into account insulation compression at the eaves
Effective R-value of windows, including glass type, fill type, spacer and framing
A typical Energy Rating (ER) for each window type
Utilized solar and internal gains
Heat gain arising from insolation, exterior roof and wall color choices
