Mechanical ELCCA Questionnaire

Topic: Standard questions for the mechanical engineer.

ELCCA Workplan

  • Is there any documentation available from the eco-charette?
  • Is there a LEED 2.2 checklist available reflecting direction from the eco-charette?
  • What 'High-Performance' system would you like to model? Recommend ground-source heat pump, as this system also qualifies as the 'Renewable' system.
  • If not ground-source heat pump for High-Performance system, than what system would you like a model as the 'Renewable' energy system? Systems qualifying as 'Renewable' in the past include displacement ventilation, and any system coupled with natural ventilation.
  • What other two systems would you like a model? Suggestions include:
    • Water source heat pump.
    • Displacement ventilation.
    • Centralized air handler with zone duct coils.
    • Two-pipe or four-pipe blower coil with VAV or FPVAV.
  • Is there a kitchen in this project, and if so is it primarily gas or electric?
  • Do you anticipate the domestic hot water system to be gas or electric?

Electrical ELCCA Questionnaire

Topic: Standard questions to the electrical engineer from the ELCCA analyst to complete PFEC form, the ELCCA workplan, and the ELCCA report.

Note 1) WSEC values shown below are for the 2006 Washington State Energy Code
Note 2) ELCCA values shown below are for the 2005 ELCCA Guidelines
Note 3) The functional area list will answer for most schools; edit as required
Note 4) Code maximum power density is less than or equal to ELCCA prescriptive for administrative, multipurpose, cafeterias, gymnasiums, and auditorium areas.

PFEC Form:

Note to the Analyst: The following questions found on the PFEC may be answered by the electrical drawings, or may require the input from the electrical engineer.

  • Fixture description including lamp and ballast type for the following functional areas:
    • Classrooms
    • Administrative
    • Multipurpose/gymnasium
    • Corridor & commons
  • If available, obtain copies the NREC forms and the luminaire schedule from the electrical engineer; these will help to answer quantitatively most of the electrical questions on the PFEC.
ELCCA Workplan:

Note to the Analyst: Upon project initiation, cut-and-paste following questions to the body of an e-mail to the electrical engineer. If a timely responses is not received, the workplan may be submitted using prescriptive values. However responses are required to the questions of this section in order to complete the ELCCA report. The workplan should be updated if the electrical engineers responses are at variance with the information submitted.
  • Fixture description including lamp and ballast type for the following functional areas:
    • Classrooms & learning commons
    • Administrative
    • Multipurpose/gymnasium
    • Corridors & restrooms
  • What are the design lighting densities in the following functional areas? (WSEC maximums/ELCCA prescriptives shown in parentheses):
    • Classrooms (1.2 /1.15 W/sf) :
    • Administrative (1.00 /1.10 W/sf) :
    • Multipurpose, cafeterias, gymnasiums, and auditoriums (1.0 /1.0 W/sf):
    • Corridors and restrooms (0.80 / 0.70 W/sf) :
  • If daylighting is provided, will control be zone switched or continuous dimming?
  • If the lighting densities in classrooms and corridors exceed ELCCA prescriptives, we must evaluate two lighting alternatives.

    • Lighting Alternative #1:
    • Lighting Alternative #2:
ELCCA Report:

In addition to the information from the preceding section, request the following data from the electrical engineer when available for inclusion in the ELCCA report:
  • Lighting layouts
  • Luminaire schedule
  • Exterior lighting power, kW
  • NREC forms, if available
  • Emergency generator power, kW
Some of the items above may not be available until near the end project, and thus will not be available if the ELCCA is to be submitted near the end of schematic design of during the design development phase.

Combining the High-Performance Building Alternative

Note page 25 excerpted from Washington State ELCCA Guidelines, which documents the acceptable criteria for using one of the previously-studied alternatives as the High-Performance Building (HPB) alternative.

According to the criteria, the HPB alternative may use ANY previously studied alternative, PROVIDED that it meets the energy savings goal of the LEED scorecard. IF the previously studied alternative will meet the energy goal only with a some modification (e.g. the addition of heat recovery and/or demand ventilation) THEN the MODIFIED ALTERNATIVE may be used as the HPB. However a modified alternative is still another alternative, and so must be analyzed equivalent to the others.

Note that the HPB alternative does not necessarily need to be based on the 'Renewable' alternative. But 'waste heat recovery' can qualify many of the systems we design as renewable alternatives (see Table 4.3 the ELCCA Guidelines, at the top of page 25), and this feature will help significantly in attaining the LEED energy goal.

So what is the 'energy goal' referred to by LEED as the benchmark criteria?

The energy goal is defined per ASHRAE 90.1-2004 Appendix G as the energy savings required of the HPB over the Baseline Building (BLB):

LEED 2.1 EAc1:

1 Point New Buildings 10.5% Existing Buildings & Renovations 3.5%
2 Points New Buildings 14% Existing Buildings & Renovations 7%
3 Points New Buildings 17.5% Existing Buildings & Renovations 10.5%
4 Points New Buildings 21% Existing Buildings & Renovations 14%
5 Points New Buildings 24.5% Existing Buildings & Renovations 17.5%
6 Points New Buildings 28% Existing Buildings & Renovations 21%
7 Points New Buildings 31.5% Existing Buildings & Renovations 24.5%
8 Points New Buildings 35% Existing Buildings & Renovations 28%
9 Points New Buildings 38.5% Existing Buildings & Renovations 31.5%
10 Points New Buildings 42% Existing Buildings & Renovations 35%


Attaining LEED Silver requires 33-38 points on the LEED Scorecard; the ELCCA Guidelines further stipulate that no less than four points shall be earned from the 'Energy Optimization' portion of the scorecard for the HPB alternative.

So, the bottom line is that the HPB alternative is required to show improved savings of 21% for new construction, and 14% for existing buildings and renovations over the BLB.

ELCCA Templates

Topic: Use modified templates to expedite the preparation of required forms.

Templates use a "prior job" format to demonstrate what the completed form should look like, and a color key macros to simplify differentiation between changed and unchanged work.

Note: The above link(s) are only valid within the HEI intranet. Firefox users install the "IE Tab Plug-in", then right-click the link and select "Open in IE Tab" from the context menu.
