Software with two modules, one for the verification of the regulation aimed essentially at residential and small commercial buildings (RCCTE), and another for the verification of the regulation aimed essentially at buildings with HVAC power higher than 25 kW (RSECE). Both modules are single zone. The RCCTE module is based on steady state assumptions, while the method for RSECE is based on a dynamic hourly simulation for a complete year, in line with the methodology adopted by the newly revised EN ISO 13790.

The hourly simulation module was compared to detailed ESP-r simulations and proven to be quite precise (within 5% for most cases).
The users shall have a basic knowledge of the thermal buildings physics concepts and a detailed knowledge of the RCCTE and RSECE regulations.
About 200 currently (Jan 2007), expected to grow over 1000 in a one-year period.
Civil engineers, HVAC engineers and Architects when designing, licensing or performing the energetic rating of buildings, for certification.
- Areas, U-values and thermal inertia of the envelope elements.
- Loss factors and linear lengths of thermal bridges.
- Solar factor and shading factors of glazed elements.
- Parameters characterizing natural or mechanical ventilation.
- Type and efficiency of the systems for domestic hot water and ambient heating and/or cooling.
RCCTE module: useful and primary energy consumption for heating, cooling and domestic hot water RSECE module: Total primary energy plus design load for sizing HVAC systems. Both: All the forms required by the regulations can be printed directly from the input and calculated values.
