BuildingServicePerformance: Draft Charter    (1DSQ)

"Building Service Performance" is an Ontolog project to formalize how we describe the purposes of facilities and the associated services expected from the building systems.    (1IG5)

The framework will define how services are requested and desired performance specified during design, and metrics to capture how the quality and performance of services is measured during building commissioning and operation.    (1IG7)

Purpose    (1IG8)

BuildingServicePerformance is technology neutral. We do not indicate technology choices or advocate particular vendor selection.    (1IG9)

Background    (1IGA)

Building Service Performance is an afterthought in building design because there is currently no accepted way for owners and designers to discuss the services desired and the performance expected for each service in simple general terms. Implementations rely on diverse technical systems delivered whose domain knowledge is not common with either owner or designer, or even the contractor. Prevailing approaches either over-specify or are ineffective in defining success after commissioning into long term operations and maintenance. Over-specifying relieves contractors from responsibility for determining the proper level of performance and limits potential benefits from innovation in the factory or field. Ineffectual specification leads to over-sized systems that perform poorly utilizing resources that could be better applied elsewhere.    (1IGB)

New demands that buildings interact dynamically with entities other than the owner and operator throughout its life will soon require that provisioning for services be managed over the lifecycle rather than procedural completeness at building turnover. Examples of such entities include power provision and emergency management. The transacted power grid will expect buildings to negotiate with remote, local, and internal energy suppliers to meet the needs of the occupants. Emergency Management will expect buildings to respond to environmental alerts, i.e., tornado warnings, to provide situational awareness after an event.    (1IGC)

The goals of BuildingServicePerformance are to enable discussion of building services and their quality between all actors over the life of the building and prepare buildings to interact with actors external to themselves. Close attention will be paid to the accuracy and privacy of certain parts of information in building models versus the ongoing access needs of the surrounding community, region, nation, and the planet as a whole.    (1IGD)

Success indicators    (1IGF)

The framework will be the basis for developing an information exchange (IDM) between control specifications and the other domains in building information modeling (BIM). Building services are defined in terms of business services provided and not in terms traditional trades. OmniClass will be used to describe the buildings, services, phases, facility types and so on.    (1IGH)

Many building service interactions are required by regulatory bodies. When these regulations exist:    (1IGM)

Business services will be defined in terms of business value creating a common lexicon for owners, operators, and tenants.    (1IGP)

Examples    (1IGS)

These examples are a thought exercise and are not intended to indicate any final product of the framework.    (1IH1)

During design, a six story building is designated as commercial space on the ground floor, a restaurant on the second, and office space for the next 4 floors. Quality indicators for all three types of space rely on the Effective Ventilation Index (EVI).    (1IGT)

Create templates for 10 facility types using BIMstorm models as samples. Using a basemap of less than 250 MasterFormat specification sections, mapped to UniFormat and OmniClass, identify the relevant building codes for each type during design and construction. The next step is to define the requirements for local, state, and Federal jurisdictions for the building in place.    (1ILA)

Building types to be evaluated are as follows, classified below by OCCS Table 11, Construction Entities by Function:    (1ILB)

To establish relationships between OmniClass>MasterFormat>UniFormat, building codes and building service performance metrics the following aspects of the sample building models will be evaluated:    (1ILM)
