Vestibule heating is prohibited when the outside air temperature is above 45☏. Significant increases were made to minimum efficiencies for variable refrigerant flow (VRF) systems. In many of these applications, ECMs are becoming more popular because of the wide speed variation compared to small, 3-speed permanent-split capacitor (PSC) motors. In this edition, ≥1/12- to 1-hp electric motors now have minimum efficiency requirements that push the industry toward 3-phase or electronically commutated motors (ECM). Networked rooms are permitted to return to occupied temperatures 60 minutes prior to expected occupancy. When unrented, the setpoint shall be ≥80☏ in cooling and ≤60☏ in heating. In the 2016 edition, hotels/motels with more than 50 guest rooms are required to have automatic controls for each guest room that raise the cooling and lower the heating setpoint temperature by 4☏ within 30 minutes of all occupants leaving the room. A table details criteria that require DDC for new buildings, alterations, and additions. These require DDC for most new building air-handling systems, chilled-water, and heating plants.
This increases energy efficiency in deadband (assuming that ASHRAE Standard 62.1 is satisfied) and lowers first cost, but increases energy use at times when peak heating is needed.ĭirect digital control (DDC) requirements were added.
The reheat limitations were modified in the 2013 edition to require a reduction in flow to 20% in deadband, and were relaxed to allow up to 50% flow at peak heating.

While the performance requirements have not changed, the standard will clarify that an inspection and verification program must be documented. And third, a new section was added that begins to address air-leakage inspections. Second, changes were made to the fenestration U-factor and SHGC, with some additional modifications made to the fenestration orientation provisions as well. First, minimum heating and cooling capacities that make a space fall into the "heated" or "cooled" categories were reduced. Of the many "in process" addendums, three stand out. The other change is that the envelope-only trade-off option rules were updated so one can use current whole-building energy simulation software. The standard expanded the areas where daylighting (called toplighting) is required in several large space types, and modified the way the window orientation/area provisions are calculated. Note, the window-to-wall ratio in 2012 IECC is 30%. The window-to-wall-ratio requirement, however, remained the same at 40%. The Building type Hospital closely resembles the occupancy, equipment load and ACH required for Gymnasium building.Insulation values for wall and window U-factor and solar heat gain coefficient (SHGC) were made more stringent.

The energy code selected for the Gymnasium is ASHRAE 2016. Also, check the box below the Energy Code to make the project a template for firmwide use(highlighted in red in the image below). Set the ‘Project Name’ as intended building use template and select the ‘Building Type’ that closely resembles to the intended use.
This article discusses the fundamentally different engineering input values to create gymnasium template. The key parameters which impact the Energy Use Intensity (EUI) include Mechanical Ventilation Supply Air Flow Rate (CFM), Lighting Power Density (LPD), Equipment Power Density (EPD), Occupancy Schedule, HVAC System Type, Envelope Properties, Domestic Hot Water Demand, Air Changes per Hour (ACH), etc. The practical knowledge of knowing one’s building use type is important to recognize the particularities of type specific energy consumption and expenditure.
Users also have the ability to validate any value assumptions with the cove.tool technical team using the Live Chat Box feature, found on the bottom left hand corner of the web app.įirst step is selecting an existing building type template. Cove.tool has pre-created templates for 8 building types but also allows advanced users to create custom template that fits the project's specific conditions.
