The Regulation of Thermal Installations in Buildings (RITE) has not yet been approved by the Colombian State, which means a delay in the certification process of current constructions. The invitation for the guild is to use it as a Good Engineering Practice.
by Camilo Botero*
There is a great problem in the air conditioning systems, which calls for a regulation in the country and in Latin America; which is why ACAIRE (Colombian Association of Air Conditioning and Refrigeration), with a determined and definitive support of ACIEM Valle Chapter and ACAIRE Western Chapter; formed a group of specialists in the field of air conditioning and took the initiative to regulate in Colombia the exercise of the professions in charge of these projects and the Regulation of Thermal Installations in Buildings (RITE) was elaborated.
To date it has had the determined collaboration of more than 2,000 hours-engineer ad honorem, with a group made up of about fourteen engineers in the specialties of mechanics, electricity and electromechanics, a document was prepared that was presented in July 2012, in the first instance to the Ministry of Mines and Energies of Colombia and that seeks to achieve impact not only here, but to become an example to follow in Latin America.
He also presented himself in the Ministry of the Environment for being responsible for the care of the environment and in the ministries of Commerce and Housing, for having a direct relationship with the equipment used and the comfort of people.
What is RITE looking for?
Establishing the energy efficiency and safety requirements that thermal installations must meet in buildings intended to meet the demand for well-being and hygiene of people, during their design and dimensioning, execution, maintenance and use, as well as determining the procedures that allow to prove their compliance, is the objective of the Regulation of Thermal Installations in Buildings, hereinafter RITE.
Also promote the safe and efficient use of refrigerants and minimize global warming and damage to the ozone layer, in order to minimize climate change.
What would be the scope?
For the purposes of the application of the RITE, fixed installations for air conditioning and the production of domestic hot water, intended to meet the demand for thermal comfort and hygiene of people who remain in offices, educational centers, hotels and shopping centers, will be considered as thermal installations.
The RITE will apply to thermal installations in newly built buildings and to thermal installations in built buildings, in relation to their reform, maintenance, use and inspection, with the limitations determined therein.
What benefits are obtained?
- Maximize energy efficiency and promote the Rational Use of Energy (URE).
- Minimize climate change and environmental preservation.
- The protection of human, animal and plant life and health.
- The prevention of practices that may mislead the user and consumer protection.
- The satisfaction of contractual and bidding requirements.
- The guarantee of the quality of the facilities with international standards.
- The generation of added value to the investment in the air conditioning system.
Why would Latin America need a RITE?
Reviewing projects, assemblies, maintenance and operation of air conditioning systems, it can be observed that there is a great deficiency in compliance with the parameters of comfort and hygiene, which are highly inefficient in terms of energy use and are not friendly to the environment.
- Normally there is no design or it is very deficient or elementally elaborated.
- The customer sometimes does not know what he is buying. You don't know exactly what you need (RDP: Owner Requirements for the Project).
- He does not see it necessary to pay for a design and with the story "if he gives me the contract, I give him the design" he stops doing it and since there is no regulation that requires it, nothing happens.
- You buy what the seller or contractor offers you, usually at the lowest cost (initial investment), even if in the life cycle of the system you pay an absurd excess for energy consumption, due to inefficiencies.
- It does not take into account the total cost in the life cycle, which includes the well-being of people or the cost of energy and other operating and maintenance expenses. He doesn't know how to compare different proposals and he doesn't know the performance of the teams.
What's going on?
- There is no regulation or codes and therefore the rules are not complied with.
- Very few projects are preceded by a design in which foreign regulations do appear, which in many cases are not complied with, due to lack of mandatory regulations.
- No measurements of energy consumption or air quality are made. No energy audits are done.
- The client has surprises when receiving the finished project: energy cost, non-compliance with air quality (temperature, humidity, dust, odors, air gusts, air stagnation).
Regulations and seals taken into account, for the RITE Colombia:
- RITE English
- ASHRAE Standards
- AHRI Standards
- NTC del ICONTEC
- EU and UNE
- SAC: Colombian environmental seal, which is being developed by the 236 Committee of Sustainable Constructions, of ICONTEC, commissioned by MAVDT (Ministry of the Environment) and the CCCS (Colombian Council of Sustainable Construction)
- LEED (Leadership in Energy & Environmental Design), Sustainable Building Certification System, developed by the U.S. Green Building Council (USGBC).
- WTO (World Trade Organization)
- Technical barriers to trade (TBT), which seeks to ensure that technical regulations and standards, as well as testing and certification procedures, do not create unnecessary barriers to trade.
Current situation of RITE (Colombia)
After two years of having formalized the project and presented to the aforementioned ministries, widely disseminated in the CIARs, ExpoAcaires, Tecnoedificios and RefriAméricas, having officially presented itself in the most important universities of the country, motivated to public and private energy companies, having written several articles on the subject in specialized journals, requesting the support of related guilds, the RITE is not yet a mandatory regulation, as they are and in good time, the RETIE, for electrical installations, the RETILAP, for lighting and the RITEL, for telecommunications (the Regulation for Boilers that also takes several years, has not been approved either).
Fortunately, ACAIRE has already incorporated it as a BPI (Good Engineering Practice) and it is available for free on its website, as well as on the ACIEM Valle Chapter website.
The current presidents of these associations are fully committed to the implementation of the RITE as well as the CHAPTERS OF ACAIRE del Occidente and Antioquia. A well-known Brazilian engineer, who has been president of ABRAVA and international vice president of that association, told me that in Brazil they had the same problem for the approval of regulations and that what they had chosen was to use the draft regulation as BPI, which over time became customary and so the State had no choice but to approve it, for it was a fact fulfilled. I invite all colleagues to do the same, with ACAIRE's BPI 09 RITE.
At the last CIAR in Cartagena during my conference that touched on the issue of normalization, when I mentioned that the RITE had not been approved by the Ministry of Energy, someone from the audience stood up and said: "It is that they have not filed it, I was told by the 'Eng. Fulanito de Tal' of the Ministry of Energy, " turning out to be the same nondescript official to whom I took it on two occasions accompanied by the presidents of ACIEM Valle and ACAIRE and to whom multiple letters have been addressed requesting the study and approval of the RITE.
For all the above I believe that the State (represented in the ministries mentioned) is having a great irresponsibility by not approving this regulation, which has nothing but benefits for all and that failure to do so will continue the waste of energy and the increase in climate change as a result of its non-application.
An engineer who works in a consulting company in the USA, and who has projects in Mexico and Colombia told me: "Doing air conditioning projects without the RITE, is like a football match without a referee ... that is, a 'recocha'...".
Another Spanish engineer, this time, told me: "How do you intend to do Leed certifications, without a RITE?"
The most common argument for not supporting rite by many Latin American engineers is to say "if we already have the ASHRAE standards, so that a regulation of our own". I answer: "First of all, ASHRAE standards are not mandatory codes and in certain issues such as climatology, building materials and technological environment, they are very different from our tropical countries."
To conclude, I invite all colleagues in the field of air conditioning to start using RITE as a Good Engineering Practice and to make all the comments, suggestions and / or corrections they deem appropriate.
