NewQUICK logo.

Thermal design and simulation tool capable of calculating loads and energy consumption. NewQuick can predict hourly air temperatures and relative humidities, which makes it a valuable tool in the passive design of building envelopes. Complete load and energy analysis of a building can further be executed in order to design an efficient air-conditioning system (HVAC). The simulation tool executes dynamic thermal calculations for realistic 'real life' temperature and load predictions. The building model integrates natural ventilation, internal load (convective and radiative), occupant load and evaporative cooling models. The simulation tool includes the modelling of external shading devices, interior mass, direct solar heat gains and ground contact surfaces.


Passive simulation, load calculations, natural ventilation, evaporative cooling, energy analysis.



Expertise Required

Basic understanding of building construction, with a minimum level of computer skills. A first time user will take approximately 5 minutes to master the preliminary input, do a calculation and view the first results.


An earlier release is used in 45 countries worldwide.


Engineers, architects, contractors, building designers and research institutions.


The program gives you two input options: a preliminary design and a detail design option. Only one input screen is used in the preliminary design option for the input of the building structure, climate, internal loads etc. For more detail a series of input screens can be used under the detail design option.


Hourly calculated indoor air temperatures, relative indoor humidities sensible and latent loads. Monthly and yearly energy results are also available. All these results are presented in tables and graphs.

Computer Platform

IBM PC-compatible, 486 or higher; Windows 95 or higher; 8 MB RAM minimum; 10 MB of free disk space.

Programming Language

Pascal for Windows


The simulation tool is very user friendly and quick to use even for a first time user. All the surface input data can be selected from a pre-constructed database, which can easily be extended by the user. The same applies for the climate database. A building of any construction, shape and size can be modelled. Unlimited number of zones and surfaces can be entered. The passive thermal and natural ventilation performance of buildings can be investigated with the tool.


The building model uses a single-zone approach. This implies that no heat exchange exist between different zones in the building. (However set temperatures can be specified on the other side of a surface to over come this.)
