Abstract The purpose of this paper is to offer a methodology for the evaluation of large district heating networks. The methodology includes an analysis of heat generation and distribution based on the models created in the TERMIS and EnergyPro software Data from the large-scale Tallinn district heating system was used for the approbation of the proposed methodology as a basis of the case study. The effective operation of the district heating system, both at the stage of heat generation and heat distribution, can reduce the cost of heat supplied to the consumers. It can become an important factor for increasing the number of district heating consumers and demand for the heat load, which in turn will allow installing new cogeneration plants, using renewable energy sources and heat pump technologies

District Heating System

Developments conceived following the principles of Athens Charter were typical form of urban answer to the post-war housing shortage and during the decades of intense construction activity that followed. In city of Belgrade, multifamily housing in open city blocks built between 1961 and 1990 account for about 40% of current housing stock. The current ownership and operation of these housing blocks derive from their socialist legacy: home-owners rights relate only to the buildings, excluding any open spaces, even the ones immediately along the building?s perimeter. On the other hand, heating is supplied by district heating system. Management of open spaces as well as provision of district heating are subordinates to local municipality (the city of Belgrade). Energy efficiency related refurbishment options for these developments that would engage both the home-owners and the public companies may be the key for bringing ever-needed modernization, prolonged lifespan and a sustainable way of using this portion of housing stock. By applying simple architectural measures, energy demand for heating of these buildings can be reduced by 30-78%, which opens a pathway for effective use of renewable energy sources. Unlike solar energy, which can be managed at building level, geothermal energy can be exploited only at the district level due to the ownership rights. The presented research explores the effectiveness of using geo-thermal energy at a district level coupled with systematic approach to building refurbishment, taking the advantage of the repetitive use of the same building design and the formal and practical relations with local authorities.

The present work examines the supply of heating and electricity to the Spanish village of Uruena, using biomass and other local renewable sources as a result of the growing interest worldwide towards the development of sustainable and energy independent small communities. Specifically, this case study considers the design of a district heating system consisting of a solar heating plant, a biomass plant using straw as a sustainable fuel for the base load and an oil boiler for the peak load, coupled with a hot water tank as a thermal energy storage option. Two alternative scenarios are analyzed for electricity generation purposes, namely a system consisting of three small wind turbines and a system with a single large wind turbine. The results show that the cost of large-scale electricity storage depends on the application and often involves significant capital investments.

Heating Energy Consumption

Over 600 million square meter heating area use the district heating system in Beijing up to 2013. The construction and operation level of many heating systems are diverse. It leads to the difference in the heating energy consumption and cost. The obstacles that impacts on the energy efficiency improvement for the district heating system in Beijing were presented. The primary job to reduce the gross heating energy consumption is to evaluate the energy efficiency of the heating system, reasonably. The aim of the paper was to provide an improved method to evaluate the energy efficiency of a district heat system.The energy conversion between the different typical parts of a heating system was discussed: the source, the primary network, the secondary network, the heat exchanger station and the building. Also, six district heating system in Beijing was evaluated by the method to illustrate the proposed technique.
