Sunpipe systems are well established in the building industry, particularly associated with energy savings. Indeed, Sunpipes with their associated products, Suncatchers and Sola-vents, have been very popular for not only piping in natural light but also for removing unwanted heat build- up. By bringing natural light and fresh air to just about every type of building, they have deservedly earned a great reputation for a simple, cost-effective and utterly reliable systems. the natural alternative!

CIBSEMay10_pp18-19 newsanalysis.indd 19 22/4/10 16:59:18 Call to industry: time to target non-compliance
As rates of compliance with the requirement for air conditioning inspections hover at just 5 per cent, CIBSE believes we need to take action. Non-compliance has real costs – it costs the environment, it will cost the UK any chance of meeting the emissions targets, and it costs non-complying companies, which are missing out on a real opportunity to increase their profits.
The CIBSE non-compliance costs campaign, backed by CIBSE Journal, is an answer to the frustration building up in the industry and a focused call to government to resolve this situation.
This campaign will address the issues of non-compliance with air conditioning inspection requirements and with F-gas legislation head on, and will gather views and support from across the industry.

Eland House Simon Weir Simon Office building housing the UK Department for Communities and Local Government
Eland House has two chillers, 11 air-handling units, a building management system, two direct expansion units and a number of terminal units such as chilled beams. The building has only been in use since 1998. The inefficiencies of the building were highlighted by the difference in the energy performance certificate (EPC) and display energy certificate (DEC) ratings. The EPC demonstrated a good modern building was given a reasonable C rating, whereas the DEC showed that there were issues with high energy usage in the building and rated the building at F. To demonstrate and test the use of air conditioning inspections, the Department for Communities and Local Government invited inspectors to look at their air conditioning systems and plant to find out how they could reduce the energy use and improve on the DEC rating. The recommendations ranged from high capital cost changes to the plant, to utilising the cost-effective ‘quick wins’, focusing mainly on controls issues and the correct operation of equipment. The total energy savings for these measures was just under 550,000kWh, or a 9.9 per cent reduction of the building energy load. This equated to 238 tonnes of CO2 and a cost saving of £32,642 per annum. The implementation costs of these measures were £8,200, which gave a payback of three months with the equivalent cost of £34/tCO2 saved. The result was an improvement of the DEC rating to an E, but is was proposed that further higher capital cost measures, such as sub-metering equipment, data reading equipment for chillers and some plant upgrades, could improve the rating further. The result was an improvement in the DEC rating and The full case study can be found in CIBSE Journal, proposals for a range of other measures February 2010, starting on page 30 Nuaire Apr10 Cibse qpg ads x3:Layout 1 15/4/10 15:22 Page 3

CIBSEmay10_pp24 letters.indd 24 22/4/10 17:00:17 The future of commercial heating is changing dramatically. Rising fuel costs and the need to reduce carbon emissions are driving the demand for renewable technology.
As heating accounts for over half of a typical building’s total energy use, it is the obvious area to target. Mitsubishi Electric have therefore pioneered a range of commercial ‘heating only’ systems using heat pump technology to meet the challenges of commercial heating for today, tomorrow and beyond.
Ideal for use in new build or refurbishment, our advanced heat pump systems are recognised as renewable technology and provide a simple, cost-effective means of meeting tough renewable energy targets.
Achieves renewable energy targets Reduces CO2 and running costs Easy to design, install and maintain Works in conjunction with other systems Maximum scalability to suit all applications Eligible for Renewable Heating Incentive (RHI)

This concerns Alfonso Ponce-Alvarez, director of marketing Peel Media Peel and international affairs at the Centre Scientifique et Technique du Batiment, which helped to set up the Sustainable Buildings Alliance (SBA). Despite this continuing proliferation of green rating systems, the SBA, a body which aims to develop common metrics in green construction, says there needs to be a global standard because of the lack of co-ordination by scheme operators. ‘This situation is profoundly unhelpful for those businesses wanting to reach a global standard,’ Ponce-Alvarez insists. But Angus McIntosh, head of research at property consultancy King Sturge, argues that analyses of which rating system is best can be short-sighted when it comes to the long-term goal of creating sustainable towns and cities.

This iconic landmark has recently completed a major investment and refurbishment of its level 12 office space, which is among the first in the UK to use all solid-state lighting. Although LEDs are not yet as efficient as the best T5 technology, they are, nevertheless, delivering savings against the previous design.

Internet protocol networks are making it easier to create integrated control systems.

There is according to experts in the industry. The ‘Such devices might do their job very well for a long currently Bdrive towards web-enabled, integrated networks is time, but eventually they will become ‘legacy’ products not enough inevitable, with more systems migrating onto the IT that can no longer offer any benefit to the building infrastructure.

Reducing operational energy consumption by deaeration and dirt removal in water systems Air, or more specifically the oxygen content in the air, that has entered a piped water system during installation or operation, corrodes the steel surfaces in heating and cooling systems creating the black sludge known as magnetite. The magnetite collects in comparatively still areas, wears out pump seals, blocks up heat exchangers and fouls valve seats. Entrained air affects the pump’s ability to efficiently circulate the water, so increasing the power required to drive the pump. This article will outline the methods for deaeration and dirt separation and illustrate the benefits of appropriate equipment application
