    hazards on front pages across the world This seminar webinar will harness the expertise of specialists from CIBSE ASHRAE and B ES to examine the role of ventilation filtration and other engineering services in turning buildings into safe havens from pollution Bjarne W Olesen Do European standards for indoor air quality take into account outdoor air quality Two European standards dealing with the indoor environmental quality is just now going through a detailed revision In the revision of EN15251 which are dealing with thermal comfort indoor air quality illumination and acoustic is used to estimate the required ventilation rate to provide an acceptable indoor air quality In general it is assumed that the outside air is clean However in this standard and especially in revision of EN13779 there are methods included to take into account outdoor air pollutants particles ozone and others Often this is done by a requirement to filtration of the outside air but also the concept of reducing the amount of outside air by using gas phase air cleaning of the indoor air is presented The presentation will briefly describe the method used in the standards to evaluate the indoor air quality and the influence of outdoor air quality Georgiana Hendriks Technical solutions for commercial buildings to ensure indoor air quality Note that seats for the free central London event 5 minutes walk from the famous Gherkin building are limited and booking is essential email iaqevent cibseashrae org with your name and email address to book a free place refreshments at 5 30pm ready for a 6pm start full location details will be emailed to you To book for the free online webinar go to https attendee gotowebinar com register 7171700201595071489 Click to read about a webinar Wednesday December 9th 2015 6pm Webinar Whose green building standards are more effective the US or Europe Tom Lawrence live from USA Sustainability is being adopted into building codes at different levels of government and with varying motivation The application of energy performance standards also varies widely across the US while in contrast the EU appears to be moving towards nearly zero energy buildings by the end of this decade due to various directives like EPBD and EED This presentation will examine and compare the current status and trends of sustainable building codes that are being adopted within the US and the EU Book your place for free at https attendee gotowebinar com register 40978069346818562 Click to read about a webinar Wednesday January 13th 2016 MIDDAY GMT Webinar Oversized air conditioning systems and overcooled buildings in hot and humid climates Chandra Sekhar live from Singapore Professor Chandra Sekhar will explore why air conditioned buildings in hot and humid climates are often so cold that one gets reminded to bring a jacket when going to the office He will consider the consequences of raising the set point temperatures as a means of improving the situation and expose some of the engineering challenges that necessitate a relook at the way air conditioned

  • Underfloor Air Conditioning in North America - report by Ewen Rose
    approach work according to Mr Arnold To get the full benefit you need very good co ordination between all the building trades throughout the design and construction process he said The implications of using a raised access floor must be considered right from the outset If the equipment needs to be maintained then ease of access is key and if it is a pressurised system then the underfloor plenum must be properly sealed to prevent uncontrolled air leakage If the plenum leaks the system will not work Division of responsibility with these systems is another potentially difficult area because it is linked to both the fabric of the building and the services so testing and commissioning must be a combined effort he explained There is a real danger of disputes between the architect builder and m e teams over this issue Managing the sequence of an installation is critical and often creates tension Who gets in first said Mr Arnold The trouble is that the builder has overall responsibility for the structure and does he really know enough about what is needed to make sure an underfloor system works Testing plenums once they are installed is easy but too late the building leakage rate needs to be addressed before the raised access floor is laid otherwise any underfloor system may only produce a small percentage of its capacity said Mr Arnold Temperature pick up in underfloor voids can also be a problem he added with the rule of thumb being a rise of 1 or 2degC per 10m between the air handling units fan coils and the plenum So the shorter the distance the better As a result of these extra difficulties clients need to be convinced that they will reap the full benefits of these systems according to Mr

  • Richard Rooley - ASHRAE President
    deep technical knowledge In the model developed by Monty de Philistone in the 1970 s this upper 1 of engineers are comparable In the Philistone model of the second and third tiers of 10 and 100 the engineering leaders have greater control of the design process in the American model STANDARDS In the USA ASHRAE writes Standards which are developed using a consensus process Public comment is central to this Each State then writes its own Building Codes often based on ASHRAE Standards In the UK Building Regulations and British Standards are written by Government and by British Standards Office with input from individuals in industry In Europe the technical representatives from each Nation make recommendations but final decisions are taken at a political level In principle ASHRAE Standards are prescriptive using check box procedures In the UK they are principally generic or performance based In energy conservation in Europe and the UK Standards have generally been for building fabric performance and structural safety Building Service elements have been an adjunct to this principally based on safety considerations In America energy standards issued by ASHRAE are system based giving specific instructions on the efficiency of components but are weak on overall building performance Comments on the education process above have led me to find that European countries with a similar education process to the British favour the European or British model Other countries including Germany countries in the Eastern part of Europe and the majority of the developing world where ASHRAE has a number of Chapters and significant technical influence favour the American model Both the British and the American systems are seriously flawed Each method has advantages world wide but rationalisation unless there is a step change in the construction process is unlikely One of the principal constraints of Standards writing is the time commitment of the participants Those who write Standards must be practitioners and are often those with a commercial interest in the balance of that Standard REHVA have reported on the differences in Standards throughout Europe The difference in approach is significant At a time when construction is an international industry faced with the constraints of global warming the need for more efficient operation health problems recognised in many buildings the absence of an international basis for Standards should be noted ASHRAE is working closely with Green Building Council to address cross disciplinary Standards in the conservation area The ASHRAE Standards required for indoor air quality including mould and energy Standards requires a development in the ASHRAE approach This is built on the traditional prescriptive Standards but is developing towards performance requirements The industry worldwide must examine what Standards are appropriate in what countries acknowledging as in Europe the independence of each sovereign state in writing Standards Can this diversity continue HOMELAND SECURITY The events of 911 has stimulated worldwide interest in security In providing its first report in January 2003 ASHRAE has provided an excellent source of risk assessment methods The report is available for download from the ASHRAE website The centrepiece of protection against extraordinary incidence in buildings is a realistic risk assessment There is a balance between cost and absolute safety The report shows that significant reductions in risk can be achieved by sensible housekeeping Simple precautions in food safety operation of filters location of outside air inlets and security awareness for visitors are all effective In high risk buildings further steps are required ASHRAE is conducting a review of all technical publications Standards and activities to ensure that the principles of Homeland Security and Risk Assessment are correctly addresses INTERNATIONALISM The telephone air travel Email and the Web have made the world smaller Technologies companies and people communicate across geographical political and language barriers As communication including television develops as the worlds resources are used to provide a better quality of life the users of our buildings have raised expectations What was an acceptable condition in buildings 20 years ago is no longer accepted These qualities are being raised worldwide Heating ventilating air conditioning and refrigeration were recognised by the American National Academy of Engineering as one of the top 10 technologies of the 20th century Food cannot be kept a good quality of environment cannot be provided in many parts of the world with ASHRAE activities There is a constant change in leadership of finance and contracting strength While America and Japan have been dominant with Europe becoming stronger and for a period Korea and other parts of the Pacific group China has now become a powerful influence In design ASHRAE members have reported a trend for design companies to sub contract technical activity to India and elsewhere This follows precedent in the computer industry Those who state that this will lead to lower quality buildings should examine the changing roles of designer contractor and manufacturer Some have argued that much of the work carried out by designers particularly following the American model can be carried out by different groupings within the construction team or indeed is largely computerised There is one manufacturer of air conditioning equipment in Italy who encourages his principle clients to specify their exact requirements on the computer Web page Not only does the purchaser specify in full detail but they can purchase production time in the manufacturing facility whether in Italy or subcontracted to China There is very little intervention by the manufacturer beyond maintenance and quality control Should this detailed specification and selection of equipment be carried out by consultant by contractor or indeed by the end user In this working across international boundaries can international Standards continue to be dominated by political pressure ASHRAE meet the challenge by providing Standards which can then be adopted by any American State or country worldwide In Pakistan the best engineers use the ASHRAE Standards on a voluntary basis As stated earlier however most ASHRAE Standards are directed at single technologies The cross interest or multi disciplinary Standards are the ones which absorb much time and effort to
