Santa Rosa, California August 25, 2014 - DesignBuilder Software has released version 4 of its popular whole building energy simulation program ‘DesignBuilder’. Version 4 adds a substantial set of new features and improvements oriented to the different but overlapping needs of architects and engineers.

DesignBuilder Packages for Architects ensure that designs meet performance targets at the early design stages by providing accurate and reliable energy and daylighting performance data. The Architectural simulation packages allow architects to link with BIM (Building Information Modeling) solutions, analyze solar shading, maximize the use of renewable technologies and test façade options in one comprehensive software program.

DesignBuilder Packages for Engineers consists of an integrated set of high-productivity tools to assist with the integration of mechanical systems within sustainable buildings design. Various design scenarios for HVAC systems and controls, facades, lighting, and renewable technologies can be evaluated with relative ease. Using drag and drop air and water components, HVAC systems can be constructed within DesignBuilder from scratch. Additionally, pre-defined HVAC templates, autosizing and zone grouping features save significant input time compared to competing products. The most commonly used EnergyPlus HVAC system types are readily available including all ten ASHRAE 90.1 baseline HVAC systems.

New features available as modules in release version 4 include:

* ASHRAE 90.1 Appendix G compatibility - ASHRAE 90.1 for 2007 and 2010 including constructions, materials, glazing systems, activities, lighting and HVAC systems for both LEED certification and IRS tax credits. * Optimization - helps identify design options with the very best combinations of cost, energy and comfort performance. * Cost - calculate the economic impact various building designs using construction cost, utility tariffs and life-cycle analysis.

All DesignBuilder packages provide sensitivity analyses at the click of a button. High quality technical and rendered outputs help communicate findings to clients in a way they can easily understand. Key performance indicators such as energy consumption, carbon emissions, thermal comfort, daylight availability and cost can be provided throughout the design process in both naturally ventilated and air-conditioned buildings.

When speaking at the V4 launch in July, Dr. Andy Tindale, founder and CEO of DesignBuilder, explained “The new functionality provided by version 4 really is a step-change in DesignBuilder’s energy and comfort modelling capabilities. Some major improvements to the modeller further enhance our existing strengths in the ability to create and edit geometry quickly and easily. The improved BIM import; enhanced LEED and ASHRAE 90.1 capability; new HVAC systems such as ground source heat pumps; tariff analysis; Simulation Manager for running parallel simulations; and, Optimisation for multi-objective cost benefit analysis have helped to strengthen our position as the leading interface to EnergyPlus.”
