Abstract

The purpose of this paper is to present the results of the feasibility study for a

district heating-cooling network to cover the energy demand in a Scientific and

Technological Park under Mediterranean climate conditions.

This study consists of three phases: energy demand, technology analysis and

economic study.

To evaluate the energy demand a bottom-up strategy has been followed: a

building inventory has been carried out to define several building types according

to use, envelope and glazing. Energy + has been used to obtain heating and

cooling demand profiles for each building type and orientation. According to

municipal development plans for PTA and forecast in business growth, the energy

demand evaluation in a 10-years timeframe has been carried out.

Most appropriate technologies has been analyzed and evaluated: cogeneration

(gas turbine and alternative internal combustion engines), biomass boiler

and conventional technologies have been evaluated with TRNSYS to obtain

consumption profiles, consumption rates, efficiency indicators and energy losses.

Finally an economic analysis has been done to technologies in a 20 years period

to evaluate technology that better economic results address.

The main objective of this work is the promotion of the efficient and effective

energy supply in areas with high energy consumption. DCH technology is

widely used in the North of Europe and this paper tries to demonstrate that this

technology could be applied in Mediterranean areas successfully.
