The University of Nottingham is adding an extension that is catching the eye of green engineers. The design is being done by Make Architects and is comprised of three landmark buildings, a public boulevard, and a 60 m high sculptural tower. Key to making the project so green is the use of high-performance facades combined with geothermal heating and cooling. A man made lake was used to handle the peak heating and cooling loads. Fresh air is delivered internally via a low-velocity, low-pressure underfloor system. All this and more makes the Jubilee extension a green wonder.

May 16th, 2009Data Center peaks in energy performance
May 9th, 2009Commercial data centers all need stable power and lots of it. They also need back up power and a back up for that power as the information they house is so important and needs to be up all the time. That does not mean that energy consumption should be a second thought. The North London Data Centre of Fujitsu became only fully certified Tier III data centre in Europe but it also has less than half the M&E services energy consumption of standard designs of such buildings. The company spent over $44 million pounds to achieve the certification but the designer believes it was all worth it and hopes other data centers follow suit.

Hot water in Modern Buildings
May 2nd, 2009As building owners scramble to meet the demands of energy conscious tenants and their ever increasing need for more power once should not overlook the way hot water is supplied. Most buildings have no excuse not to use solar powered hot water heaters that can deliver green friendly hot water to just about any modern building if the design is done correctly. However in large buildings even the best system can only deliver about 30% of all the hot water needs so a back up plan muct be planned out just as carefully. For high hot water use buildings like hotels gas powered hot water heaters are still the answer in both cost and going green mentality.

Proper disposal of condensate
April 25th, 2009Since the law changes to Building regulations in 2005 building maintenance crews are careful of the proper disposal of condensate from boilers. Since these boilers make up some 98% of all boilers in the UK it is imperative that the waste is managed correctly to maximize efficiency of those boilers. In most cases condensate can be removed through the normal gravity drain with out any issues. But, if a boiler has to be installed on internal walls or within basements the use of a boiler condensate tank pump or soak away should be looked into to make sure of proper disposal. In no shape or form should a boiler condensate be leaked straight out to the ground.

Making VRF systems better
April 18th, 2009As all the gear for building-services systems is gets more efficient. That principle applies to boilers, electric motors, lamps — and VRF air conditioning. It all sounds good but one needs to make sure that just because you purchased and installed the most efficient parts you can find that they all work well together to make the system as a whole the most efficient it can be. A common problem is the positioning of outdoor units, which are often in confined spaces or positioned close to other heat sources, increasing the immediate local temperature and, as a direct consequence, their efficiency. Make sure to plan out any system properly for maximum efficiency.

Electrical Services Scheme on display
April 18th, 2009The large exhibition hall at National Exhibition Centre at Birmingham has developed a sophisticated way to monitor and control power. The complex system goes on to control how much ( if any ) power goes to any particular show stand and if that power will be one or three phase. This is seen a revolutionary breakthrough and many exhibitors will be watching how it works during the next show. This new technology could easily be adapted to modern buildings allowing each tenants power to be controlled, monitored and billed from one central location which would reduce overhead costs substantially.

Using chilled beams to cool buildings
April 18th, 2009The idea of using a cooled beam system in modern buildings is a great way to consume less power and be more eco-friendly. The invention is rather new but one that is sure to become popular quite quickly. Waterloo’s technical manager Wander ter Kuile says that: Chilled beams operate with a chilled-water flow temperature of 14°C, which is inherently more energy-efficient than the 6°C that is typically used with fan-coil units. Indeed, such a high flow temperature might obviate the need for a chiller and certainly increases the viability of geothermal cooling, for example, where the temperature of the ground during a year may not rise above 12°C.’ It sure sounds like the way to go in power savings.

Investing in sustainability
April 18th, 2009While the global recession is taking its toll on the bottom line of many businesses it should not play a factor in making the investment of going green. Lowering carbon emissions is key for any property hoping to make it out of the downturn. By investing in a slow market you are sure to find a better deal on making those much needed upgrades. As the market swings back up those who are prepared will see a much better return on their properties for going to a more sustainable emissions strategy. Investing in your long term future could be the best short-term plan for any property business.

Electrical heating making comeback
April 18th, 2009With advancements in technology you will see many modern buildings getting back to using electricity for heating applications. The knock on electrical heating has always been the wasted power and high carbon emissions of electrical boilers. That is all changing now as some UK boiler manufacturers are introducing boilers that run at over 98% efficiency which makes for little waste. The new boilers also lower carbon emissions making them green friendly and could see a big resurgence in new buildings starting now and in the near future.

Do we need more carbon savings?
April 18th, 2009Over the past few years everyone has been talking about lowering the carbon emissions in modern buildings. Over the last decade we have seen commercial heating systems go greener and greener with the wide spread use of condensing boiler technology and the development and introduction of low- and zero-carbon solutions, together with improvements in building design and materials such as insulation. It has made sense on many levels for both consumers and manufacturers to go green as it often saves money and resources in the long run. Any new building construction takes this all into account as they build which should put a stop to all the new regulations the government is always trying to mandate.
