LOTUS Interiors: Credit E-1 Space Cooling

 

Intent

To reduce the need for cooling by increasing natural air flow and to encourage the installation of energy efficient HVAC systems.

 

Requirements

Criteria

6 points

Strategy A: Natural Ventilation

10 % of occupied areas are naturally ventilated

1

1 point for every additional 15% of occupied areas that are naturally ventilated

(up to 85%)

6

Strategy B: COP improvement

10% improvement of COP for direct electric air-conditioners AND 5% improvement of COP for water-chilling systems in comparison to QCVN 09:2013 requirements

1

1 point for every further 10% improvement of COP for direct electric air-conditioners AND further 5% improvement of COP for water-chilling systems in comparison to QCVN 09:2013 requirements

4

Strategy C: HVAC Zoning

Provide separate HVAC control zones for each solar exposure and for areas with different usage/occupancy needs

1

Strategy D: HVAC Controls

1 point for each of the following strategies implemented:

–       Use variable speed controls on all the air-conditioning systems

–       Install a demand control ventilation system for spaces with special occupancies

2

Strategy E: Alternative strategies

1 point for each of the following strategies implemented:

–       Install energy recovery ventilation systems on all air handling units

–       Use a radiant cooling system

–       Install mounted fans in 50% of occupied areas

2

 

Please note that for this credit, HVAC systems installed and managed by the base building can be used for compliance as long as they serve the project space.
