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 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.
Identification of the causes of corrosion in the pipes of a heating system
The heating system in a public building of recent construction shows an abnormally advanced phenomenon of corrosion in its pipe network, and different factors are being considered as a cause: inadequate choice of pipe, excess air in the pipes from an inefficient deaeration, and biological corrosion by bacteria.
Identification and analysis of the European assessment requirements applicable to cold rooms
Characterization of the components used for assembling modular construction cold rooms (sandwich panels, substructures, doors and ancillaries for assembly and sealing) with respect to the requirements of thermal insulation, air permeability, fire safety, safety in use and hygiene. It has also addressed the issues of maintenance, repair and cleaning.
Criteria for the design and installation of fireplaces and chimneys in timber frame buildings
Good practices and safety criteria for installing fireplaces for solid fuels in single-family wood-frame buildings, covering the usual box fireplaces in the market, either freestanding or inserts. Guidance on the correct location, condition of the base and the contiguous walls, air intake, geometry of the chimney and caps.
The heating market in Spain
Market research on boilers and hot water production, measuring consumption in volume and value in a series of product types according to the type of fuel, power and features. It includes historical series and forecasts based on the trends of the demand and the building rules, and market shares of the leading players.
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.
Characterization of the demand for heating boilers and appliances for hot water production
Description of the most popular choices for boilers and hot water production equipment, including which are the most frequent setups with their average costs, usage profiles (frequency of operation, annual energy consumption), maintenance costs and lifetime of the devices.
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.
Heating systems in residential buildings in Spain
Characterization of the heating systems already in use in Spain, and contrast with the total park of buildings, with details of the type of fuel used and distinguishing between central and individual systems. Estimation of energy consumption for specific heating purposes (kWh/year). 10-year trends on the park of buildings, park of systems and fuel market shares.
