Design HVACSystems(Programming)

The term "programming" is the process of developing a program. Programming includes the assessment ofneeds/requirements and delimitations/constraints. These are described as a program (e.g. in Norway usuallyaccording to Norwegian Standard NS3451). Delimitations can be physical (e.g. area type and size, spaceprogram), technical (e.g. number and type of outlets, or type of materials), time based (e.g. projectprogress) and financial (e.g. investment budget or LCC). The programming stage accounts for the client'sassessment of the requirements to be met by the completed construction and forms the basis fordetermining the budget.

[Outlineconceptualdesign(4)]


Design HVACSystems(Sketch)

The term "sketch design" is the process of developing an interdisciplinary design where the propositions fromthe design team describe relevant alternative main principles and main system solutions (in Norway usuallyaccording to Norwegian Standard NS3451). The alternatives are presented with pros and cons. The designteam's recommended design solutions for further study at the full concept stage are stated, along withproposed reports to be carried out at the full concept stage.

For HVAC systems, this process includes determining:

Estimate of load to determine main flow moving device (fan) sizeIdentify main vertical routes using indicated spacesLocation, sizing and identification of technical spacesCosting for presentation is by high level aggregation elementSpecification of types of system and principles of operation.Sketch design model showing technical spaces, vertical distribution routes, and key horizontal routesto describe principal routing.



Design HVACSystems (FullConcept)

The term "full concept design" is the process of developing an interdisciplinary design where the propositionsfrom the design team describe a recommended solution (in Norway usually according to Norwegian StandardNS3451). At this stage all relevant principles and system solutions for all disciplines are stated, qualitativelyand quantitatively. Estimated Life Cycle Cost (LCC) for the design shall be provided. All succeeding stagesare in principle regarded as "production stages" (i.e. production drawings / models, the physical building,documentation). The full concept design level of detailing should be sufficient to avert later principle /system decisions with quality, progress or economic implications, unless a change is done in programmingrequirements. Further detailing and smaller changes of design solutions at later stages are considered to benormal and acceptable.

[Full conceptualdesign(5)]


Design HVACSystems(Coordinated)

The term "coordinated design" is the process of developing a detailed interdisciplinary coordinated designwhere design team deliverables include a building information model that contains characteristic productspecification attributes (in Norway usually according to Norwegian Standard NS3420) suitable for a tenderprocess, including supplementary demands for test procedures, component labeling, documentation etc. Anumber of additional reports may also be required (e.g. environmental issues reports, LCC according toNorwegian Standard NS3454, waste handling procedures, universal (handicapped friendly) design

Delimitations can be physical (e.g. area type and size, space program),technical (e.g. number and type of outlets, or type of materials), time based (e.g. project progress) and financial (e.g. investment budget or LCC). The programming stageaccounts for the client's assessment of the requirements to be met by the completed construction and forms the basis for determining the budget.

For HVAC, the process includes determining:

Space program requirements for HVAC systems to meet technical requirementsIdentification of requirement for technical spacesIdentification of requirement for vertical distribution spacesIdentify what types of system are relevant

Process Overview


Stage(s)

2.1.1 Task Estimate Load

For the project as proposed, make an estimate of the expected overall HVAC load so that a preliminary estimate ofthe size of the flow moving device (fan, pump etc.) can be made.

Information for estimating loads at the programming stage will typically be derived from previous, similar projectsor from collected 'rules of thumb' (which are effectively aggregated data from multiple previous, similar projects).Such calculations will make broad assumptions about contributions to load resulting from lighting or other energysources rather than using information contributed to the building model from other roles.


2.1.2 TaskEstimate SpaceRequirements forTechnical Spaces

Makes a preliminary estimate of the space required for major technical spaces to serve the HVAC systems on aproject.Major technical spaces are spaces that have a substantial impact on building consideration either in terms of theiroverall size or their structural implication (special floors etc.).Other (minor) technical spaces will be determined at the sketch design stage.Estimate of the space requirement may include height requirement (e.g. need for 5m height for the type ofequipment being considered).Example: A major technical space could be for a chiller or cooling tower plant space or plant room.The estimate is based on experience, knowledge of previous projects, industry guidance etc. Typically, it isdetermined on a factor based method that takes into account total space area and space function. Non indicatedspaces such as circulation space, storage space etc. may be accounted for in total building space by furtherparameters. This can also be used in accounting for space required to accommodate further expansion that may bemandated by the space program.



2 af 4 11-09-2011 18:25

2.1.3 TaskDefine SpecialSpaces

Special spaces are spaces that may require more detailed elaboration at the programming stage. Typically, they arespaces that have particular, detailed requirements and are not represented as a space type within a libray of suchtypes held by a client.Example: A 'Ship Simulation Room' at Tromso College is used to train ships officers by providing simulated viewsfrom the bridge of a ship. This space is modelled in detail even at the programming stage to enable considerationof the particular design requirements of the space.


2.1.4 TaskDefine Location andSize of TechnicalSpaces

Propose the location and size of major technical spaces - from previous process (not minor technical spaces). Thisshould be based on the space requirements previously identified.Location of spaces includes the configuration relative to adjacent spaces in the case of there being any constraintsor requirements as to room type X adjacent to room type Y. E.g. plant room and fan chamber should be adjacent toeach other.


2.1.5 Task Estimate Cost

For the project as proposed, make an estimate of the order of magnitude cost. Order of magnitude costing willlargely be based on cost information from previous projects.

Specifics for Norwegian Practice

Costing uses NS3453 and is likely to be based on sq.m prices against known previous example buildings.NS3457 is standard table for building categories.

Process Overview


2.2.3.1Sub-Process(collapsed)

Select DistributionMethod

Decide on the distribution method of the HVAC system. E.g. central air/air distribution, local air/water system etc.Note that several alternative sketch designs may be proposed, each design using an alternative distribution method. Final choice of the selected method ismade at the full concept design stage.



Decide DistributionRoutes

Using spaces allocated to systems decide main distribution routes. This is for main air ducts throughout the project only; branch ducts are not routed atthis stage.

The objective of determining the distribution route is to ensure awareness of main routes and sizes for distribution.



Estimate Loads atSignificant Points

Estimate the load to be met at significant points along the main distribution routes.[Outline conceptualdesign(4)]


Sum LoadsAdd the estimated loads progressively back to the estimated point at which the fan will be located. This will provide an estimated load on each section ofthe main distribution route and a total estimated load which the fan(s) is required to meet.



Calculate DistributionSystem Sizes

From the loads determined for the main distribution routes, estimate the required largest duct size.This is used for allocation of space within distribution zones and also for coordination purposes.



Estimate Diversity FactorEstimate a diversity factor for HVAC supply that considers the expected maximum simultaneous load on the system given that not all HVAC distributionmay be required at the same time.



Model Typical SpaceLayouts

Detailing of equipment layouts and duct branch routes in typical 'spaces' that enable cost models to be better informed.[Outline conceptualdesign(4)]


Connect SystemElements

Make connections between distribution system elements and allocate flow directions.[Outline conceptualdesign(4)]


Regulate SystemsDeals with the selection,placement (where not already done through a prior process), sizing (by reference to the distribution elements to which regulatingelements are connected) and establishment of regulation setting to achieve the degree of regulation required.

The term "full concept design" is the process of developing an interdisciplinary design where the propositions from the design team describe a recommended solution (inNorway usually according to Norwegian Standard NS3451). At this stage all relevant principles and system solutions for all disciplines are stated, qualitatively andquantitatively. Estimated Life Cycle Cost (LCC) for the design shall be provided. All succeeding stages are in principle regarded as "production stages" (i.e. productiondrawings / models, the physical building, documentation). The full concept design level of detailing should be sufficient to avert later principle / system decisions withquality, progress or economic implications, unless a change is done in programming requirements. Further detailing and smaller changes of design solutions at later stagesare considered to be normal and acceptable.

The objective of the maintain elements and systems activity for a project is to perform those actions and adjustments required to return elements and systems to asatisfactory state (physical or functional) for continued operation. The activity is concerned both with planned and unplanned maintenance activities and considersrequirements that may be state (failure or imminent failure), time or condition based.

A maintenance requirement is triggered by an event which may be caused by either:

the amount of time that has elapsed since the previous maintenance operation was carried out has reached the planned interval between maintenance operations, orthe date on which a maintenance operation is planned has arrived, orthe current operating condition of an element, group of elements or system as determined by the values of one or more parameters has reached a level at whichmaintenance is set to occur, oran operational failure (either complete or partial) has occurred that requires a maintenance operation to correct.

In the context of the above, maintenance is also considered to encompass replacement where an element has reached the end of its working life.

The HVAC Design role covers the development of heating, ventilating and air conditioning systems to satisfy the requirements of the design brief, cost plan, buildingconfiguration, sustainability and health and safety brief, national and local legislation and the energy analysis data. The process of designing HVAC systems involves theselection and specification of appropriate equipment, distribution networks and terminal units to meet the project objectives. It also includes the coordination of thesesystems within the building model, with reference to the architecture, structure and other services. The output of the HVAC design process includes the model of the HVACsystems, and their technical and performance specification.

6 TaskMaintainElements andSystems

The objective of the maintain elements and systems activity for aproject is to perform those actions and adjustments required to returnelements and systems to a satisfactory state (physical or functional)for continued operation. The activity is concerned both with plannedand unplanned maintenance activities and considers requirements thatmay be state (failure or imminent failure), time or condition based.

A maintenance requirement is triggered by an event which may becaused by either:

the amount of time that has elapsed since the previousmaintenance operation was carried out has reached the plannedinterval between maintenance operations, orthe date on which a maintenance operation is planned hasarrived, orthe current operating condition of an element, group ofelements or system as determined by the values of one or moreparameters has reached a level at which maintenance is set tooccur, oran operational failure (either complete or partial) has occurredthat requires a maintenance operation to correct.

In the context of the above, maintenance is also considered toencompass replacement where an element has reached the end of itsworking life.

Please ensure that you have read the process mapping document Energy Analysis (PM) before proceeding with this exchange requirement.

The scope of this exchange requirement is energy analysis at the programming stage of a project where programming is considered to include both outline and substantivefeasibility. The result of programming is that a feasible approach to the energy analysis of a project has been determined.A basic building model is defined as 'the set of information that provides both a graphical representation of the design of a building and key pieces of information about thebuilding that can be further used to analyse building performance' (from Autodesc )During this stage the information available is limited to the basic requirements. These include:

a building is requiredit should be of a particular type or perform a particular function (several functions may be identified within a particular type)it should be located in a particular place and on a particular site (several alternative locations may be identified; each location should be dealt with individually)it has an estimated overall area and/or volume requirement OR it is related by a size factor to a similar previous project about which information is knownthere are factors that affect the 'order of magnitude' cost including (but not limited to) items such as

expected building configuration (e.g. multi-storey as opposed to single storey)expected structural complexity based on ground conditionsexpected level of servicing for operational and comfort purposesaccessibility of the locationlabor resource availability

Particular information that is required to determine 'order of magnitude' cost includes:

the name of the project (for identification purposes) and the units generally used throughout the project;the current stage of the project; whilst this is generally optional, it should be mandatory for this exchange requirementthe location and expected area of a site on which a building is to be located (the shape representation of a site is not necessary for this Exchange Requirement)the building or buildings for which the cost is required (at least one building must be specified although the shape representation of a building is not necessary forthis Exchange Requirement)the area, volume or size factor of the buildingvalues for factors that may affect the cost

factors may be applied to the building directly or individually determinede.g. services costs may be on a volume or size factor basis

classification of objects for collection into groups and assemblies for costing purposes

Exchange of information about shape, size and location of HVAC components.

HVAC systems information can then be brought together with equivalent information from other roles to ensure that items of equipment are in proper spatial and functionalrelationship to each other taking into account their size and location in terms of space allocation and structural provision.

Please ensure that you have read the process mapping document HVAC Engineering (PM) before proceeding with this exchange requirement.

This exchange requirement allows for the provision of information at various stages during the design process including outline conceptual or sketch design, full conceptualdesign and coordinated design. The information provided at each stage is essentially the same. However, the level of certainty regarding equipment and components usedwill increase at each stage allowing greater certainty in space provision.

It is assumed that the information provisions outlined in the exchange requirement er_exchange_HVAC_model (space) have been satisfied. This provides an initialassessment of spaces from the perspective of building design and HVAC design as well as project details.Information provided through this exchange requirement includes:

HVAC component type and sizeRequired electrical connection load and control/starting methodRequired piping connection loads for each service typeRequired control system interfaces and system logicShape representation of component (using an appropriate representation form that may be symbolic, 2D, 3D boundary representation etc.); the form ofrepresentation to be used and the extent of detail that is provided for the component may differ at different stages of the project.Weight (and optionally center of gravity) of component typeLocation and orientation of occurrences of component type

The requirement to specify duct networks would not normally be required, but may be necessary where the imposed load of the ductwork exceeds normal structural designcriteria, for example fire rated ductwork constructed of heavy guage materials.

Equipment Weight

As well as the placement and shape of components, the weight of major items needs to be captured and communicated to ensure structural coordination. This isdetermined by the HVAC Design role using the functional part fp_define_quantity.For each item of equipment:

Information Needed MAN REC OPT

Identify the method of measurement to be usedThis should be set to a value that is agreed to represent a weight value for coordination purposes. For instance, a value such as 'Structural WeightCoordination' might be usedNote that at later stages in the design, weight of components may also be supplied in property sets. This is significant for product information derivedfrom a library. However, for structural coordination purposes and to maintain consistency in building modeling, it is recommended that the quantitymeasure is used.

Exchange of information about technical spaces for HVAC plant and equipment and how other spaces are grouped for system development and fire compartmentation. Usedto coordinate with general zoning and spacing requirements with other roles.

Please ensure that you have read the process mapping document 'pm_HVAC_engineering' before proceeding with this exchange requirement.

The scope of this exchange requirement is the exchange of information to enable provision of technical spaces, spaces zoned for HVAC systems provision and firecompartments with particular HVAC systems requirements. The purpose of the exchange requirement is to enable coordination of HVAC systems requirements with othertechnical systems requirements (notably electrical and piping systems) and with building design with regard to the provision of space for the technical systems.

This exchange requirement allows for the provision of information at various stages during the design process including outline conceptual or sketch design, full conceptualdesign and coordinated design. The information provided at each stage is essentially the same. However, the level of certainty regarding equipment and components usedwill increase at each stage allowing greater certainty in space provision.It is assumed that the information provisions outlined in the exchange requirement er_exchange_building_model have been satisfied for the project stage concerned. Thisprovides an initial assessment of spaces from the perspective of building design and project details.

Information provided through this exchange requirement includes:

HVAC component type and size - Note that, for the purposes of this exchange requirement, only those HVAC components having significant size and requiringlocation within a technical space need to participate.Shape representation of component typeLocation and orientation of occurrences of component typeProposed technical space specification with area, configuration and height - Note that, at earlier stages of design, area and height only may be given; later stages ofdesign may also propose a space configuration.Grouping of spaces into zones served by an identified system

Information may be optionally provided concerning material from which elements are constructed and their classification.

For HVAC design, technical spaces are spaces that have as their primary purpose the housing of electrical or other technical equipment.Technical spaces are subject to 'negotiation' between the building designer and technical designers. It is therefore expected that suggestions made by the HVAC designerwill be applied in the building model through quantities rather than by making changes to space configuration provided.Thus, for a space that is a technical space:



Identify the method of measurement to be usedThis should be set to a value that is agreed to represent a suggestion made by the technical designer. For instance,a value such as "Technical Space Reconciliation" might be used
