HK BEAM BACKGROUND

ANNUAL ENERGY USE

Commercial
1 to 3 credits for a reduction in the maximum electricity demand by 15%,23% and 30% respectively.

Encourage energy conservation and methods to reduce peak electricity demand
-Escalators reduce speed when not in use or on standby
-LED lighting systems

ENERGY EFFICIENT SYSTEMS

Encourage the design of structural elements and choice of materials thatresults in lower embodied energy.

-building foundations, building core, walls,

VENTILATION IN COMMON AREAS

Ensure adequate ventilation in common areas and circulation routeswithin premises and to avoid cross-contamination between areas.

the ventilation system to be capableof providing sufficient fresh air taking into account the anticipated population

intake and exhaust points be properly designed to preventcontamination of fresh air supply and avoid short-circuiting

the ventilation system and its associated ductwork, where provided, should be conveniently accessible for maintenance.

MEASUREMENT APPROACH?

THERMAL COMFORT

Ensure that the air-conditioning system can provide the stated design conditions in occupied spaces under changing load conditions.
The HVAC system should be possible to maintain room conditions

LIGHTING QUALITY
-NATURAL LIGHTING

Encourage a holistic examination of site layout, building design, andfenestration design, such as to maximiseaccess to daylight for the purposes of improved health and comfort

window and room geometry and room surface finishes
sky obstruction due to the form of the building and its overshadowing from neighbouring buildings
glazing transmittance

INTERIOR LIGHTING IN NORMALLY OCCUPIED AREAS

Embrace both ‘quantity’ and ‘quality’ of the lighting system performance including: maintained horizontal, and whereappropriate vertical, illuminance, illuminance variation, limiting glareindex, colour rendering, and modulation of light output appropriate to thetype and use of the premises/indoor spaces
