Fergus NicolOxford Brooks UniversityChapter 1 - EnvironmentalCriteria for Designwww.cibse.org
Purpose of Chapter 1This chapter is intended to delineate the environments that buildingoccupants will find comfortable.The interaction between people and buildings takes place in a number ofways, and many aspects of the environment are important: the thermal environment (both inside the building and outside) the lighting the ventilation any noise or vibration.The chapter brings together information in all these aspects and triesto give the best and most up-to-date information on which buildingservices engineers can base their designs.www.cibse.org
Thermal environment and comfortLargely rewritten in the main with sections on Comfort Thermal environment, defining variables and looking at the 6 basicvariables Models of thermal comfort – adaptive and PMV. How they are derived,how they differ and what they have in common Environmental criteria for indoor spaces.www.cibse.org
Thermal environment and comfortOverheating: reflecting the criteria for overheating introduced in TM52Additional factors affecting comfort including personal factors such as age,gender, state of health as well as environmental factors such asasymmetry, floor temperatures, draughts and turbulence and the influence ofother dimensions such as lighting on thermal comfort.Each section reviews the available evidence and its reliabilitywww.cibse.org
Outdoor thermal comfortAn entirely new section which addresses the importance of the outdoor environmentand how it can be optimisedRequirements for outdoor airLooks at the need for fresh air and how it can be affected by therate of supply and the need to control pollutants. Indoor AirQuality is addressed in chapter 8www.cibse.org
Noise and VibrationTwo sections have been thoroughly rewritten Noise deals with the measurement and effect of noise viewing soundboth as a means of communication and as a source of discomfort. Thesection give plentiful references to guidelines and standards Vibration is dealt with from the point of view of the danger is poses tobuildings and their occupants dealing with sources as well asconsequenceswww.cibse.org
Visual environmentLighting for Safety and visual performanceThe criteria for daylighting and the role of energy efficiency in lightingThis section has been shortened and readers are referred to the publications of theSLLReferencesThere is a copious list of references which can be used forfurther readingwww.cibse.org

Thermal bridging Of potentially increasing significance as insulation of structures is raised Heat loss calculations should include the effect of thermal bridges andthe Guide indicates how they can be evaluatedwww.cibse.org
Martin LiddamentVEETEC LtdChapter 4 – Ventilation andInfiltrationwww.cibse.org
Chapter 4 Ventilation and Air InfiltrationAt the time of preparation issues about the future of ventilation methodsand the impact of infiltration on energy consumption were important.Considerations included:Airtightness – Legal requirements to reduce CO2 emissionsVentilation more mechanised to provide controlThe Future of Natural Ventilationwww.cibse.org
Background: The Future of Natural VentilationBuilding Regulations(June 2009 Consultation Volume 1)“It is likely to become morechallenging to provide adequateventilation rates using naturalventilation systems and this willgive impetus to mechanicalventilation systems”.www.cibse.orgNHBC (2012)“In order to satisfy the energy use demands ofthe Code for Sustainable Homes in homes builtto Code Level 4 and above, it is expected thatmechanical ventilation with heat recovery willneed to be applied in order to achieve anacceptable indoor climate, which representssomething of a culture change in the UK.
However Many UK Organisations promote natural ventilationSaving Carbon –Improving HealthThe Carbon Trust: “A typical airconditioned building has double theenergy cost and associated CO2emissions of a naturally ventilatedbuilding. It is also more likely to haveincreased capital and maintenancecosts”.The Commission for Architectureand the Built Environment(responsible for UK secondaryschool design): “Many basicissues of energy performancehave been overlooked includingthe potential to minimisemechanical ventilation by usingpassive ventilation”.www.cibse.org“Buildings designed with passiveventilation haveimproved resilience to energysupply failure and aremore energy efficient thanmechanically ventilatedbuildings. In an acute hospital up to70% of net floor space could beentirely or partially naturallyventilated”.
Background: OutcomeStill a strong demand for buildings to benaturally ventilatedMuch progress on the implementation ofmechanical systems in buildings that wereformerly naturally ventilated (e.g. dwellings)Many lessons still to be learnt about ventilationperformance in practice and about the impact ofairtightnessA continuing need to consider all aspects ofair infiltration and ventilation in Guide Awww.cibse.org

Major changesMore emphasis on importance of air movement as a mechanism for moisturetransportLiquid water storage and movement within porous materials forms an essential partof advanced prediction models to BS EN 15026IntroductionNew paragraphs emphasising the importance of air leakage into structures as amechanism for moisture transport into fabric, and therefore the need to limit airleakage.www.cibse.org
7.3 Psychrometry of water vapour in airExpanded version of previous 7.6.1, with simple psychrometric chart to explainderivation of parameters.www.cibse.org
7.4 Moisture content of materialsEquation for sorption isotherm, relating moisture content of material to the ambientRH introduced. Parameters of the equation introduced to expanded Table 7.1www.cibse.org
7.5 Mechanisms of moisture movementNew section 7.5.3 discussing role of surface buffering in controlling internal humidity.New section 7.5.5 discussing liquid water movement through pores, which is thedominant mechanism in the more advanced models under BS EN 15026.Section 7.5.6 on air movement expanded.www.cibse.org
7.7 Interstitial CondensationExpanded from the old 7.6.5, with new sections 7.7.1 Risks of interstitial Condensation, 7.7.2 Diffusion (Glaser) model, 7.7.3 Drying of components with entrapped moisture 7.7.4 Full models, which discusses the models standardised in BS EN 15026, i.e.WUFI.www.cibse.org
7.8 Inside and outside design conditionsGenerally unchanged from the old 7.7, but with the addition of climate classesdefined in BS EN ISO 13788 and BS EN 15026.New sections 7.8.5.2 and 7.8.5.3 on boundary conditions for ground floors.www.cibse.org
7.9 Condensation calculationsGenerally unchanged from old 7.8, with addition of new section 7.9.2.5 Condensationin the insulation of cold pipes, where calculations use cylindrical coordinateswww.cibse.org
Current DevelopmentsDCLG have just let an 18 month contract to PRP Environmental for a completereview of knowledge and research in this area; once that is complete towards theend of 2016 they will start the process of revising Approved Document CHistoric Scotland Technical Paper 15, by Joseph Little, which should be publishedshortly, is a major analysis of the processes concerned with moisture risks ininsulated solid masonry wallswww.cibse.org
Current DevelopmentsAnalysis based on BS EN 15026 (i.e WUFI) is being increasingly used, in place ofthe traditional ‘Glaser’ method in BS EN ISO 13788, without there being clearguidance as to which method is appropriate for any given system.It is apparent that the distinction that has been made between problems of ‘interstitialcondensation’ and problems from other moisture sources, especially driving rain, isunhelpfulBS 5250, will be completely revised in 2017www.cibse.org
