New programs

Building energy rehabilitation analysis (Spain)

Royal Decree 235/2013 of the 5th April, which transposes Directives 2002/91/CE and 2010/31/UE, regulates the Basic Procedure for energy certification of buildings, for both new and existing buildings which will be sold or leased as of the 1st June.

CYPE’s building energy rehabilitation analysis program “Estudio de rehabilitación energética de edificios” generates the “Energy efficiency certificate for existing buildings” (using the results output from the program: CE3x), the “Estimate for improvement measures” to obtain a superior energy qualification (with one or several improvement hypotheses) and the economical, static (Payback) and dynamic (VAN) analyses of the period required to recover the investment carried out for the improvements of each hypothesis.

CYPECAD MEP

CYPECAD MEP for Spain

Summary of the HE 2013 update in CYPECAD MEP

On the 12th September, Order FOM/1635/2013, of the 10th September, was published in the BOE (Official State Bulletin) Num. 219 (I. DISPOSICIONES GENERALES, MINISTERIO DE FOMENTO). This order updated the Basic Document DB HE “Ahorro de Energía” (Energy Saving), of the CTE (Spanish Building Technical Code), approved by Royal Decree 314/2006, of the 17th March.

As of the 2014.i version, a new tool and changes have been implemented in CYPECAD MEP to ensure the new DB-HE is complied with.

Now, with the 2014.k version, the following are included:

• Improvements in the Thermal analysis performed by CYPECAD MEP.
• CYPECAD MEP’s analysis and results are updated to include the modifications of the new HE 3 section – Energy efficiency of lighting installations.

Thermal analysis – HE 1

The model CYPECAD MEP generates to be exported to CYPETERM HE (analysis motor of CYPECAD MEP to analyse and justify the new CTE DB HE 1 2013) has been corrected.

Users can also select the residential use profile to be used when calculating the energy demand, in a similar manner as to how it done from this version of CYPETERM HE.

Lighting – HE 3

As of the 2014.k version, CYPECAD MEP’s analysis and results incorporate the modifications indicated in Royal Decree 314/2006, of the 17th March regarding section HE 3, “Eficiencia Energética de las Instalaciones de Iluminación” (Energy Efficiency of Lighting Installations).

Users can choose between designing in accordance with the CTE DB-HE 3 of 2006 or with the modified document, CTE DB-HE 3 of 2013, by selecting the code to be applied from the General data menu.

Amongst the implemented changes (when the CTE DB-HE 3 of 2013 is selected) are:

• A new check of the limited power installed for the lighting in the building, taking into account the power of lights and auxiliary equipment, in accordance with section 2.2 regarding the power installed in the building.
• Changes carried out on the table containing the limiting energy efficiency values of the installation, on the activity zone types and limits of the limiting values for each of them.

Update of job examples

The “Vivienda unifamiliar” and “Bloque de 8 viviendas” examples are updated. Their analogous examples are also updated in the CTE reports.

Thermal analysis for France

RT 2005 and RT Existant

As of the 2014.k version, the program allows users to carry out a simplified analysis that optimises the time taken to run through the first phases of the design. A simplified description of the building envelope is used without taking into account close and distant shadows, and regroups, as much as possible, elements with similar thermal properties (transmittance, orientation...). Users can carry out a final analysis without applying this simplification.

CYPETERM HE (Spain)

Export of the hourly results of the energy simulation of the building

As of the 2014.k version, users can obtain the hourly evolution of the design thermal zones using a new export command, which allows for the variables to export for each zone to be selected and the number of thermal zones of the model to be included in the CSV export.

More information can be found on our Spanish webpage.

Selection of the residential use profile to be used when calculating the energy demand

Users can choose between two residential use profiles, from the “General Data” menu of the HE 1 2013 analysis, or from the “General parameters” tab within CYPETERM HE.

More information can be found on our Spanish webpage.

Arquimedes

Correction of the DXF or DWG measurement which did not allow for the “Linear length” measurement or “Delete measurement” button to be used in specific cases with the previous version (2014.j).
