ENERGY AUDITS

ISSOS Energy Projects is governed by the UNE-EN 216501: 2009 energy audits.

This UNE standard establishes the requirements that an energy audit must have so that it can be comparable and describe the key points where it can be influenced to improve energy efficiency, promote energy savings and avoid greenhouse gas emissions.

ENERGY CERTIFICATES

Royal Decree 235/2013, of April 5, which approves the basic procedure for the certification of the energy efficiency of buildings.

The Royal Decree establishes the obligation to make available to the buyers or users of the buildings an energy efficiency certificate that must include objective information on the energy efficiency of a building and reference values such as minimum energy efficiency requirements in order to that the owners or tenants of the building or a unit of it can compare and evaluate their efficiency energetic.

The minimum energy efficiency requirements of buildings or units thereof are not included in this Royal Decree, as they are established in the Technical Building Code. In this way, assessing and comparing the energy efficiency of buildings, will favor the promotion of buildings with high energy efficiency and investments in energy savings. In addition, this royal decree contributes to the reporting of CO2 emissions from the use of energy sources in the residential sector will facilitate the adoption of measures to reduce emissions and improve the energy rating of buildings.

ENERGY SIMULATIONS

The team of Engineers of ISSOS Energy Projects is at the forefront of these computer programs. Most of this software uses the DOE-2 program as a calculation engine, carried out by the US Department of Energy, and the Berkeley laboratory of the same nationality.

It´s probably one of the most prestigious energy analysis programs in the world. ISSOS Energy Projects uses eQuest and Calener, both based on DOE-2.

On the other hand, our team also works with TRNSYS, software that was originally developed for solar processes, then it was expanded and focused on the simulation of buildings and HVAC systems.
TRNSYS is a complete and expandable simulation environment for the simulation of transient systems.
