The rapidly increasing energy consumption rate poses an alarming Over the past decade, the idea of smart homes has been conceived threat to the worldwide environmental sustainability and economic as a potential solution to counter energy crises or to at least mitigate stability. International Energy Agency’s (IEA) statistics reveal that its intensive destructive consequences in the residential building 32% of the total final energy is being consumed by the buildings sector. Smart homes have emerged as one of the applications of [1]. This percentage is even higher in non-industrial areas. In recent Internet of Things (IoT) that enabled the use of technology to years, energy efficiency and saving strategies have become a automate and customize home services with reference to users’ priority objective for energy policies due to the proliferation of preferences. However, the concept of smart homes is still not fully energy consumption and CO2 emission in the built environment. matured due to the weak handling of diverse datasets that can be According to statistics [2], globally, 40% of all primary energy is exploited to promote more adaptive, personalised, and context being consumed in and by the buildings and contributes 30% of the aware capabilities. Furthermore, instead of just deploying CO2 emissions [3]. In many developed countries, the buildings are integrated automated services in the homes, the focus should be to considered as highest energy consumption sector than bring the concerns of potential stakeholders into consideration. In transportation and industry. For instance, in 2004, building sector this paper, we have exploited the concepts of ontologies to capture has consumed 40%, 39%, and 37% of total primary energy in USA, all sorts of data (classes and their subclasses) that belong to one the UK and the European Union [2].

Studies [13] also reveal that consumers even with an demand and their detrimental environmental impact due to gas adequate knowledge of how to save energy and also with a emissions and global warming, manifest a dire need of reforming professed desire to do that could still be unsuccessful to achieve energy efficiency policies especially in building sectors. This also this goal. Frederiks et al., [13] believe that this could be linked with urges potential stakeholders such as occupants, energy providers, people’s values, attitudes and intensions and their observable housing agencies, policy makers and environmental groups to set behaviours which is commonly agreed as knowledge-action gap their goals that are in consistent with the government policies and value-action gap.

  • SFA Guide to Open Fire Installation
    SFA Guide to Open Fire Installation Solid Fuel Association 95 High Street Clay Cross Chesterfield Derbyshire S45 9 DZ www.solidfuel.co.uk Open Fires Introduction If the open fire is the main heat source in a room then to comply with Approved Document J 1A and 1B the minimum efficiency of the finished installation must be at least 37%. To achieve this, the installation will need to meet BS 8303and have a sealed in, controlled, open fire. The installation of a simple inset open fireback is not an easy task and must be undertaken correctly and with care. If this is done it will provide the end user with many years of trouble free use. The main components commonly employed in a typical installation are as follows:- 1. Fireback or boiler set 2. Throat forming lintel 3. Fire surround and superimposed hearth 4. Appliance Note: the appliance should be constructed in accordance with BS 4834 and with components (items 1 to 4 above) manufactured to the requirements of BS 1251 (Specification for open fireplace components). When manufactured to these requirements, a minimum efficiency of 37% is deemed to have been met. Where an inset open fire includes a boiler, the efficiency must be confirmed using the test given in BS 4834. All of the above components are installed or fixed to an appliance recess supported by a constructional hearth both of which are fully described later in this chapter and additional information in BS 8303. The installation methods described later deal with fireback or boiler set into a recess where a new surround is to be fitted or where the existing tiled surround is to be used.

  • TB) 101 Replaces the Version Originally Published 1 April 2009 Which Is Now Withdrawn
    Technical Bulletin 101 Developed with HSE Title: HSE Safety Alert Risks from redundant solid fuel back boilers Date issued: 1 September 2010 Note: This version of Technical Bulletin (TB) 101 replaces the version originally published 1 April 2009 which is now withdrawn. This version has been reviewed and where appropriate revised to ensure that it remains both current and relevant. This Technical Bulletin alerts Gas Safe Registered businesses/engineers to the HSE Safety Alert related to risks from redundant solid fuel back boilers Introduction The Health and Safety Executive (HSE) in Great Britain (GB) has issued a Safety Alert aimed at homeowners, tenants, landlords and heating professionals following five incidents in GB since 2008, where redundant solid fuel back boilers have exploded. The HSE have stated that “a number of these incidents led to injury and sadly, in one case, a fatality”. The risk can arise when a disused solid fuel boiler which has not been safely decommissioned has been left at the back of a fireplace and a coal or wood fire is lit in front of it. This can mean that the boiler heats up causing the boiler casing to explode. Therefore, if you have (or know of) a redundant solid fuel back boiler you should not light an open fire in front of it. The HSE believes information published in its 2008 Safety Alert should help identify whether individuals have this potential risk in their properties/housing stock and what steps they should take. The HSE is urging those who are unsure of whether they have a redundant solid fuel back boiler behind their fireplace to seek further advice from their landlord or a competent professional such as a Gas Safe registered business.

  • British Engine Boiler Insurance Company Limited
    British Engine, Boiler and Electrical Insurance Company Limited, 1878- 1991 Location and extent of archival material: SS4/2-8, 57 boxes The listing has been completed in box number order and there has been no attempt to arrange material into series as the collection simply includes a large selection of miscellaneous company catalogues. Company history The Company was founded in Manchester on November 12 1878 under the title of ‘The Engine and Boiler Insurance Company’ with RB Longridge as Chairman and Micheal Longridge (his nephew) as Chief Engineer. The Longridge family were established engineers at the beginning of the 19th Century. They were originally iron masters of Bedlington, Northumberland who also supplied castings and forgings to the engineers of the day. They were involved in the early development of industrial steam engines and were business partners with both George and Robert Stephenson. Members of the Longridge family continued to serve the Insurance Company from the early days until the introduction of nuclear power. RB Longridge formed The Steam Boiler Assurance Company in 1859 but later resigned. Following his resignation he formed ‘The Engine and Boiler Insurance Company Limited’. Within two years the name changed to ‘The Engine, Boiler and Employers’ Liability Company Limited’. In 1903, the Silver Jubilee year the title ‘British Engine, Boiler and Electrical Insurance Company Limited’ was adopted, and in 1978 the title was abbreviated to ‘British Engine Insurance Limited’. The family association terminated in 1966 with the retirement of HM Longridge. The name of Longridge was perpetuated in the title of the Head Office building in Manchester- Longridge House, erected in 1959 on a site embracing that of the original Manchester Steam Users Association of which RB Longridge was Chief Inspector.

  • Analysis of Boiler Efficiency– Case Study of Thermal Power Stations
    ANALYSIS OF BOILER EFFICIENCY– CASE STUDY OF THERMAL POWER STATIONS 1.0 INTRODUCTION Looking to the statically data, rate which power demand increases is extremely very high compared to the rate at which generation capacity increase. Boiler is a heart of power plant, so its efficiency is directly affected to the all over efficiency of the plant. It is quite obvious that approximately 65% to 70% power generation comes out from Thermal Power Plant uses Coal as fuel available from various parts of India, where transportation is also made easy and timely. Power is one of the basic infrastructures necessary for the Industries and socio economic development in the State. Installed capacity of the State has increased from 315 MW in 1960-61 to 11711 MW in 2009- 2010. Per capita consumption of power in the State of Gujarat in 2008-09 was 1446 Units (as per CEA revised formula) which is almost double of all India average. For finding out the Power Plant efficiency and its performance, the Ukai and Gandhinagar Thermal Power Plants are being selected for the present study. The performance of boiler was carried out by way of calculating the efficiency of Boiler by direct method and indirect method. It has been also discussed the methods how GSECL (Gujarat State Electricity Corporation Ltd.) calculate the efficiency of Boiler. The important discussion on the point how to increase the efficiency of Boiler. The study scope encompassed the following major tasks: • Discussion of methods to reduce the heat rate of existing power plants. • Preparation of case studies quantifying heat rate reductions resulting from the methods described herein.
