Documentary, budgetary and legal compliance check of the renovation of the HVAC system in a health facility

Before tendering the renovation of the air conditioning system of a healthcare building, a preliminary examination of the executive project has been carried out. It contemplates the replacement of the current equipment with variable refrigerant volume units featuring heat recovery, with the additional difficulty of keeping the existing ventilation and electricity systems. The project assessment has identified some conflicts derived from the complexity of the operation, in which 8 heat pumps and 77 indoor units will be installed.

Assessment of air renewal mechanical systems

Assessment of air renewal mechanical systems

Assessment of a mechanical ventilation system for non-residential buildings in relation to the indoor air quality and thermal efficiency criteria of the Spanish CTE building code and RITE regulations for HVAC. These systems perform a continuous measurement of the internal CO2 level and self-regulate the airflow rate towards the room accordingly. It includes a method to calculate the number and size of the equipment that guarantees air renewal in each space with the least possible energy loss.

Regulatory framework for plastic chimney systems

Regulatory framework for plastic chimney systems

At the time of writing this report, the EN 14471 standard was still in a preliminary phase and the Spanish code for installations was awaiting a new revision. As a result, chimneys and smoke ducts made with plastic materials were left in a situation of legal ambiguity. In these circumstances, the manufacturer was informed of which were the options available to present technical evidence of the proper functioning of his systems, mainly in the field of voluntary certification.

Evolutionary vertical ventilation

Evolutionary vertical ventilation

The Spanish building code RITE of 1998 started to set a standard of how much outdoor air volume was required to guarantee the quality of indoor air in buildings and, as a result, forced ventilation systems become necessary. The study focused on how these new standards affected housing construction, and what kind of market alternatives were available, analyzing their performance and cost.
