New database items on water supply
A water supply company has its own technical specifications for designing how its distribution network should connect properly with the interior plumbing of the building. ITeC has checked the database items concerning pipe penetrations and meter boxes that can be found in the company’s construction elements database and has made them consistent with these specifications.
Database for waterworks repair projects
A drinking water supplier already has a database for estimating construction budgets for building large and small diameter networks; but in practice, a substantial part of its activity requires to work in the existing network when it breaks down. Therefore, a new database of execution costs and specifications has been created with specific items regarding the repair of leaks, cracks and joints in different types of pipes.
Assessment of fireproofing solutions for pipe penetrations
The fire resistance of walls and floor slabs is compromised in those points where pipes go through, so if it is critical to guarantee their integrity in case of fire, specific sealing elements such as intumescent collars must be used. The evaluation has required to determine on a case-by-case basis how much fire resistance time can be expected according to the type of collar, material and geometry of the pipe, and components and geometry of the wall or floor.
Requirements for clamps for gas pipes
List of requirements for the fixation clamps used in gas piping, based on the Spanish gas regulation and also other non-regulatory technical documents that are nevertheless accepted as good practice. It provides a reference for manufacturers for positioning their offer.
Evaluation of piping systems with press-fit connections
Procedure for assessing steel pipes and fittings assembled with pressfitting techniques that use a tool for applying pressure and forming a permanent connection. The requirements vary according to the type of use (drinking water, hot water and heating, solar thermal, gas distribution and sprinklers) because each application is regulated by different building codes.
Regulatory requirements affecting a range of pipe fittings
Requirements that affect a range of fittings for joining pressure pipes, including the following issues: need to obtain a type approval (certificate of conformity), feasibility of CE marking (existence of harmonized standards for these products) and convenience of a voluntary certification (after testing the specifications and evidencing production control)
Impact of European legislation on sanitaryware
Analysis of the state of European standards affecting sanitaryware built with materials different than ceramics, such as shower trays. It describes the different options for CE marking in a specific moment when the EN 14527 standard was still in draft form.
Greywater reuse systems
Reusing greywater (from showers and wash hand basins) has the potential to save up to 45% of water consumption. This study analyses the feasibility and cost of adding greywater systems in new buildings, concluding that it does not involve a significant increase of the execution budget.
Industrialized kitchens and bathrooms
Cross-analysis of the types of bathrooms and kitchens most frequently used in social housing developments, with the industrialised products that can be found on the market. The greatest potential is detected in bathrooms; so their competitiveness against conventional methods has been assessed in terms of performance and cost.
Solar collectors for domestic hot water production
Evaluation of the possibilities of implementation of solar thermal energy in residential buildings as per the demands of urban ordinance of the City of Barcelona. It is based on a state of the art of the solar systems for hot water production available in the market, focusing on issues such as cost and the availability of knowledgeable installers of this kind equipment.
