Energy Efficiency and Planning

For TTA, energy efficiency and planning have been fundamental objectives in its work across various fields and geographic areas, whether at the level of a single building, industry or sector, or on a regional scale, with the aim of rationalizing energy consumer behaviour and introducing renewable energies.


Design and construction plans for ICE’s new Energy Control Centre (CENCE)

Costa Rica

ICE | Instituto Costarricense de Electricidad
2012 - 2013

This contract was awared by ICE to the consortium TTA-IDOM and local companies, Ossenbach Pendones & Bonilla, IEA and Circuito, including the initial participation of RCAA from Quebec, for the services related to the design and construction plans for the new CENCE’s facilities.

This new facilities will become ICE’s headquarters and the new energy control centre of Costa Rica which operates the National Electric System. ICE’s objective, as a public entity, was to have a new building which concept would be based in sustainable principles, seeking to minimize the impact on the location and in the area, energy self-generation and integrated management of resources such as the water cycle. The goal for ICE was for this building to become an emblematic example and showcase for the country and for Central America.

TTA carried out the activities related d to sustainability and energy efficiency, as well as the bioclimatic architectural aspects. IDOM jointly with the local companies executed all the architectural and engineering to fulfill ICE’S technical requirements, particularly those called for by a critical infrastructure, as well as for risks control (seismic conditions, storms) common in Costa Rica.

CEDRO Technical Back-stopping for the CEDRO Programme


UNDP | United Nations Development Programme - Líbano
2008 - 2012

The CEDRO programme consists of developing the use of Renewable Energy and Energy Efficiency in three regions undergoing reconstruction.

Trama TecnoAmbiental (TTA) is providing all technical assistance services as well as conducting training and capacity-building activities within the objectives of the programme, which are:

  • To improve and secure 24-hour electricity access for public facilities (hospitals, schools, municipalities, etc.).
  • To increase the energy efficiency of public buildings through demand-side management analysis.
  • To implement approximately 60 pilot installations in the three target regions using all relevant technologies. Through the systems installed in hospitals and schools, there has been a reduction of between 60% and 70% in the consumption of diesel used for supplying hot water.
  • To monitor and evaluate the installations after implementation.

Sun For Med Sustainability within the framework of the Programme Invest in Med


COPCA | Consorci de Promoció Comercial de Catalunya / ACC1Ó / Generalitat de Catalunya

The objective of this consultancy was to conduct a benchmark analysis of the solar photovoltaic sector in the Mashrek region. The analysis made key data available to guide the investment decisions of potential investors, particularly those interested in this region. A manual was produced describing the study of photovoltaic solar energy in different business areas, as well as foreseen business and investment opportunities in the countries under study.

Study on possibilities of use and promotion of development of solar energy

Bosnia and Herzegovina

IMG | International Management Group en nombre de la Agencia AECID
2008 - 2009

The objective was to examine the possibilities in Bosnia and Herzegovina for the application of both photovoltaic and solar thermal energy, considering the development of different strategies for their implementation in the country. Trama TecnoAmbiental carried out an analysis of supply and potential demand for both technologies, as well as of the institutional and regulatory framework. In addition, a feasibility study for the implementation of domestic and international financial mechanisms was conducted. As a result of these analyses, a strategy to promote the use of these technologies was outlined, and complementary awareness raising campaigns and university-based training activities were proposed. Finally, sites for pilot projects were selected and documentation was prepared for tenders and supervision of works, commissioning and monitoring.

DOSBE – Development of electrical operators for poverty reduction


Programa IEE – Coopener - Comisión Europea
2007 - 2008

Using its specialized technical expertise, Trama TecnoAmbiental developed specific solutions to strengthen electrical service operators and contribute to institutional and financial policies for the integration of sustainable RET (renewable energy technology) systems.

The main objectives of the DOSBE project were focused on making legislation and environmental and financial restrictions compatible with the development of operators for the provision of electricity services in remote areas of Ecuador and Peru. To this end, TTA based its work on past and present experiences with service operators in rural areas and, taking into account international benchmarks, developed guidelines for the service operators according to the institutional models of each country, as well as technical and regulatory standards for the integration of decentralized RET systems.

Final design for the installation of air conditioning and ventilation in the Marc de Vilalba Library


Ayuntamiento de Cardedeu

This building houses a public library, with space for public ceremonies, offices, storage and machine room, with a floor area of 1,600 m² and a maximum occupancy of 200 people. The building is made up of three floors: a basement, a ground floor and a first floor, and its main façades are oriented towards the south and north, organized in three wings.

Through the installation of heating and cooling systems, the whole building is serviced, thus, the required indoor environmental conditions are guaranteed in each area. The building’s ventilation is forced and air conditioned, with heat or “cold” recovery from used air. For the generation of heat and cooling, geothermal heat pumps are used. This system is capable of providing heating or cooling power with an electrical performance at least twice as high as that of air-source heat pumps.

The elements that make up this air conditioning system are:

  • Back-up gas boiler, for peak heating needs (30-32 kW).
  • Buffer tank.
  • Geothermal exchange: battery with polyethylene pipes (flow and return) in eight vertical ground perforations, approximately 100 m deep.
  • Two 33 kWt heat pump units.
  • Heat or cold transmitters: under-floor heating and air conditioner units.
  • Diffusers for displacement air distribution.

Study of renewable energy Integration and energy efficiency measures


ATLL | Aigües Ter-Llobregrat
2006 - 2007

Trama TecnoAmbiental provided the following consultancy services:

  • A study of the technical and economic feasibility of photovoltaic integration in the company’s facilities, with an emphasis on the feasibility of connecting the photovoltaic systems of the various buildings and facilities to the grid. Other renewable energy sources such as wind, solar thermal and biomass were also included. The total power proposed in the study was 5,800 KWp.
  • Technical design of energy efficiency solutions, including energy recovery through hydraulic turbines in pressure reducing valves in water pipes. These solutions were focused on the improvement of electric motors, frequency inverters, efficient lighting, hybrid vehicles and the kinetic energy recovery systems mentioned above.
