Consumer Guide: Balancing the Central Heating System
Consumer Guide: Balancing the central heating system System Balancing Keep your home heating system in good working order. Balancing the heating system Balancing of a heating system is a simple process which can improve operating efficiency, comfort and reduce energy usage in wet central heating systems. Many homeowners are unaware of the merits of system balancing -an intuitive, common sense principle that heating engineers use to make new and existing systems operate more efficiently. Why balance? Balancing of the heating system is the process of optimising the distribution of water through the radiators by adjusting the lockshield valve which equalizes the system pressure so it provides the intended indoor climate at optimum energy efficiency and minimal operating cost. To provide the correct heat output each radiator requires a certain flow known as the design flow. If the flow of water through the radiators is not balanced, the result can be that some radiators can take the bulk of the hot water flow from the boiler, leaving other radiators with little flow. This can affect the boiler efficiency and home comfort conditions as some rooms may be too hot or remain cold. There are also other potential problems. Thermostatic radiator valves with too much flow may not operate properly and can be noisy with water “streaming” noises through the valves, particularly as they start to close when the room temperature increases. What causes an unbalanced system? One cause is radiators removed for decorating and then refitted. This can affect the balance of the whole system. Consequently, to overcome poor circulation and cure “cold radiators” the system pump may be put onto a higher speed or the boiler thermostat put onto a higher temperature setting. -
Microgeneration Strategy: Progress Report
MICROGENERATION STRATEGY Progress Report JUNE 2008 Foreword by Malcolm Wicks It is just over two years since The Microgeneration Strategy was launched. Since then climate change and renewables have jumped to the top of the global and political agendas. Consequently, it is more important than ever that reliable microgeneration offers individual householders the chance to play their part in tackling climate change. In March 2006, there was limited knowledge in the UK about the everyday use of microgeneration technologies, such as solar thermal heating, ground source heat pumps, micro wind or solar photovolatics. Much has changed since then. Thousands of people have considered installing these technologies or have examined grants under the Low Carbon Buildings Programme. Many have installed microgeneration and, in doing so, will have helped to reduce their demand for energy, thereby cutting both their CO2 emissions and their utility bills. The Government’s aim in the Strategy was to identify obstacles to creating a sustainable microgeneration market. I am pleased that the majority of the actions have been completed and this report sets out the excellent progress we have made. As a consequence of our work over the last two years, we have benefited from a deeper understanding of how the microgeneration market works and how it can make an important contribution to a 60% reduction in CO2 emissions by 2050. Building an evidence base, for example, from research into consumer behaviour, from tackling planning restrictions and from tracking capital costs, means that we are now in a better position to take forward work on building a sustainable market for microgeneration in the UK. -
The Role of Micro-Generation Technologies in Alleviating Fuel
The role of micro -generation technologies in alleviating fuel poverty In a bid to ease the burden of fuel poverty, social housing providers are increasingly turning to micro-generation technologies to help reduce fuel costs. However, with many different types of micro-generation technologies on the market, designers need to know which technologies offer the best chance of alleviating fuel poverty The aim of the study was to determine the The three different types of micro-generation impact of micro-renewable energy technologies technologies were evaluated across three in alleviating fuel poverty. In particular, it sought different case study schemes in South to establish which micro-renewable energy Yorkshire and the West Midlands. Evaluation technologies offered the most cost-effective of the technologies involved monitoring their means of alleviating fuel poverty; and the factors performance, interviewing residents, collecting that influenced the cost-effectiveness of such longitudinal household energy consumption technologies. In doing so we focused on three data and modelling the financial payback of types of technology: ground source heat pumps the systems.

Legal Regulation of Aircraft Engine Emissions in the Age of Climate Change
Legal Regulation of Aircraft Engine Emissions in the Age of Climate Change by Jin Liu A thesis submitted to University College London for the degree of Doctor of Philosophy June 2011 Faculty of Laws UCL 1 I, Jin Liu confirm that the work presented in this thesis is my own. Where information has been derived from other sources, I confirm that this has been indicated in the thesis. _____________________________________ Jin Liu 2 Abstract Although the contribution of international civil aviation to climate change seems small (with a global share of just 3.5 percent of emissions of CO 2), the projected growth in air traffic means that it is highly significant. There is thus an urgent need to explore legal regulations for limiting and/or reducing the adverse impacts of aircraft emissions on the environment. This thesis examines the progress which has been made on international aviation emissions abatement and provides an analysis of the reasons for delay. It concludes that the contribution of aviation to climate change is a multi-scalar problem and as such neither conventional top-down international legal regimes, nor any single regulatory instrument can solve it. The research question for this thesis is how to break the deadlock of conventional legal approaches and overcome the barriers to international aviation greenhouse gas emissions abatement. New governance theory provides the theory within which the future of aviation emissions regulation has been explored. Drawing on the scholarly literature on new governance, this thesis argues for a multi-scalar regulatory architecture which simultaneously engages multi-level governance, and a multi-party and multi-instrument approach to the problem. -

Passive House Cepheus
PASSIVE HOUSE CEPHEUS • The term passive house (Passivhaus in German) refers to the rigorous, voluntary, Passivhaus standard for energy efficiency in buildings. It results in ultra-low energy buildings that require little energy for space heating or cooling. A similar standard, MINERGIE-P, is used in Switzerland. The standard is not confined only to residential properties; several office buildings, schools, kindergartens and a supermarket have also been constructed to the standard. Passive design is not the attachment or supplement of architectural design, but an integrated design process with the architectural design. Although it is mostly applied to new buildings, it has also been used for refurbishments. Thermogram of a Passive house Explain the difference CEPHEUS - Passive Houses in Europe.mht • Passive Houses require superior design and components with respect to: • insulation • design without thermal brigdes • air tightness • ventilation with heat recovery • comfortwindows und • innovative heating technology • To realise an optimal interaction of all components, an energy balance of the building has to be worked out. And step by step any new design may be improved to meat Passive House sta HOW? WALL FLOOR WALL WINDOW Space heating requirement • By achieving the Passivhaus standards, qualified buildings are able to dispense with conventional heating systems. While this is an underlying objective of the Passivhaus standard, some type of heating will still be required and most Passivhaus buildings do include a system to provide supplemental space heating. This is normally distributed through the low- volume heat recovery ventilation system that is required to maintain air quality, rather than by a conventional hydronic or high-volume forced-air heating system, as described in the space heating section below. -

To recover more industrial exhausted heat, a new low-temperature central heating system integrated with industrial exhausted heat using distributed electric compression heat pumps is put forward and analyzed from the aspect of thermodynamics and economics. The roles played by the distributed electric compression heat pumps in improving both thermal performance and financial benefit of the central heating system integrated with industrial exhausted heat are greater than those by the centralized electric compression heat pumps. The proposed low-temperature central heating system has higher energy efficiency, better financial benefit, and longer economical distance of transmitting exhausted heat, and thus, its configuration is optimal. For the proposed low-temperature central heating system, the annual coefficient of performance, annual product exergy efficiency, heating cost, and payback period are about 22.2, 59.4%, 42.83 ¥/GJ, and 6.2 years, respectively, when the distance of transmitting exhausted heat and the price of exhausted heat are 15 km and 15 ¥/GJ, respectively. -
