2014 Integrated Sustainable Building Design


General Guidelines

The category of Integrated Sustainable Building Design (ISBD) is intended for undergraduate or graduate students of mixed disciplines with enough training to work collaboratively on the building, mechanical and electrical design. ASHRAE recommends that the team for the ISBD consist of at least three members with education covering architecture/construction, mechanical (HVAC) engineering, and electrical engineering.

These multidisciplinary teams will be expected to design an energy efficient sustainable project approaching a “Zero Energy” building with minimized energy demands for HVAC and all other technical systems that could be satisfied with locally available and/or building installed Renewable Energy Sources (RES). Students will be asked to satisfy ASHRAE Standard 189.1-2011 and then implement RES to approach “Zero Energy” if possible.

The fundamental goal of this design competition category is to encourage students to obtain experience in the ISBD process. Architects and engineers should work together from the very beginning to determine building orientation, layout, materials, mechanical systems, and electrical systems that meet the client’s needs and work with the surrounding environment to minimize energy consumption. Additionally, special attention should be given to sustainability, the needs of the future shall be as (or more) important as the needs of the present when designing the building layout and integral systems. The judging criteria will be centered on ASHRAE Standard 189.1-2011; thus, areas of judging shall include Site SustainabilityWater Use EfficiencyEnergy EfficiencyIndoor Environmental Quality, the Building’s Impact on Atmosphere-Materials-Resourcesand Construction and Plans for Operation.

 

Specific Design Guidelines

Architectural
The design should be connected to the site, of appropriate scale, and minimize its impact on its surroundings. The team should adequately describe the selected site; each team should select an appropriate site for their project consistent with sustainable site selection practices such as those in ASHRAE Standard 189.1-2011.

The building envelop shall conform to ASHRAE Standard 189.1-2011 as a minimum, this includes (but is not limited to) glazing, walls, roofs, fenestration, and foundations. The basic layout of this 2-story building shall include administrative offices, reference library & document archives, website support/computer room, a clean room, shipping and receiving areas, a staging area for off-site activities, with new research & development areas. The interior wall construction shall be sensitive to noise transmission such that minimal noise shall be transmitted from one space to any adjacent space. If elements of the building are not clearly defined, refer to ASHRAE Standard 189.1-2011 for clarification.  Esthetic appearance is important; as such building systems (mechanical & electrical) shall not be visible if possible.

Per ASHRAE Standard 189.1-2011, the building is classified as “Long Life”; thus, the sustainable life cycle analysis shall be 40 years and all building decisions shall be based on this assumption. This assumption shall also be integral to decisions on building orientation, shape, envelop construction and materials, and systems within the building to maintain functionality, purpose, and energy efficiency. Spaces within the building shall be adequately sized for service and sustainable practices.

The team shall include per ASHRAE Standard 189.1-2011 integrated combinations of building shading and natural day lighting to reduce electrical loads within the building. Additionally, teams shall include as a minimum the mandatory space requirements for PV power per Standard 189.1-2011 in the efforts to reduce peak electrical demand and annual electrical consumption. Per Standard 189.1-2011, teams shall illustrate how the building will shave 5% of the peak electrical load through a combined balance of architectural, mechanical and electrical design; while still maintaining the comfort levels of occupants, per ASHRAE Standard 55-2010, within the building.

MEP Systems
The minimum team goal is to meet ASHRAE Standard 189.1-2011 levels of efficiency, which is 30% better than ASHRAE Standard 90.1-2007. Teams shall include illustrations of projected annual building energy consumption (including plug load), this annualized energy consumption shall be shown in Energy Use Intensity (EUI) value units of kBtus/ft2. Teams from outside North America wishing to locate the building in their capital city may illustrate their EUI in Mj/m2.

Teams shall illustrate their mechanical and electrical systems of choice such that examples of energy efficiency meeting (or exceeding) ASHRAE Standard 189.1-2011 are included. Demonstration of acceptable Indoor Environmental Quality shall also be included; examples could include (but are not limited to) human comfort, ventilation effectiveness, and building air pollutant control.

Lighting levels within ASHRAE Standard 189.1-2011 shall be maintained or exceeded, demonstration of this shall be illustrated by each team. Inclusive of the lighting level control shall be all outside lighting to illustrate the reduction of Backlight, Uplight and Glare (BUG) to the building site. Teams shall include examples of lighting level control (occupancy control, daylight control, etc…) to illustrate reductions in overall building energy footprint.

Sustainability
Per ASHRAE Standard 189.1-2011 teams shall include a “Plan for Building Operation”. Teams shall develop a means for the building owner to document steps during the construction phase, commissioning phase, and operational phase which will provide sustainable performance plan for the building, its functionality for occupants, and its EUI performance for the future. Teams shall include examples from Standard 189.1-2011 on how this would be implemented and maintained for future utilization.
Per the performance option of the Energy Efficiency section of Standard 189.1-2011, teams shall illustrate annual building production of CO2 emissions from utility consumption.

Utility Usage and Life Cycle Considerations
Teams shall assume the following for utility service and life cycle elements available to the ISBD team and building owner.

Grid supplied electricity, natural gas, city water, and city sewer shall follow the “Utility and Service Life Overview” document.

Life Cycle Factors shall include escalation, inflation, return on investment rate, and life span per the “Utility and Service Life Overview” document.

Design Parameters and Assumptions
Refer to the Owner’s Project Requirements for design parameters and assumptions.  Assumed people activity and related impact on building thermal loads shall follow ASHRAE Standard 55-2010 and the Fundamentals handbook; the team shall illustrate assumed levels of people activity and its impact on the building load.

Building structural, architectural, mechanical, and electrical elements shall conform to ASHRAE Standard 189.1-2011 as a minimum. Teams have the freedom to exceed this standard if specific examples exist and are intended to be used by the team for purposes of demonstrating superior building performance, such use shall be stated and illustrated.

If the team is moving the building to their native capital city, the team shall state any assumed design parameters which may differ from the items within this document and/or ASHRAE Standard 189.1-2011 for clarification.
