Conference Rooms
Discover the energy-saving potential of your conference room with Rayzeek’s occupancy sensor design guide.
Maximize Energy Efficiency in Conference Rooms with Occupancy Sensors
Conference rooms are integral to the functioning of any commercial building, serving as the hub for meetings, presentations, and brainstorming sessions. These rooms are often equipped with high-intensity lighting to ensure visibility during presentations and discussions. However, due to their intermittent usage, they are prone to high energy wastage. Lights are often left on when the room is vacant, leading to unnecessary energy consumption.
Moreover, the sporadic usage of conference rooms means that they often remain vacant for extended periods, leading to unnecessary energy consumption if the lights are left on. This wastage not only impacts the building’s energy efficiency but also contributes to higher operational costs.
With Rayzeek’s occupancy sensors, you can transform your conference room into an energy-efficient space, meeting the requirements of energy codes and contributing to a greener environment.
에너지 코드 준수
국제에너지보존코드(IECC)는 건물 에너지 효율성을 위한 최소 설계 및 시공 요구사항을 규정하기 위해 ICC(International Code Council)에서 개발한 모델 코드입니다. IECC는 최신 에너지 절약 실천법과 기술을 반영하기 위해 3년마다 개정됩니다.
IECC를 주목해야 하는 이유
IECC는 미국 전역의 주 및 지방 자치 단체에서 널리 채택되고 있습니다. IECC는 건물 외피(벽, 지붕, 창호), 난방 및 냉방 시스템, 조명 시스템을 포함한 에너지 사용의 다양한 측면을 다룹니다.
IECC는 다양한 구역의 빈 공간에서 발생하는 에너지 낭비를 최소화하기 위해 점유 감지 센서와 같은 특정 조명 제어 장치의 설치를 의무화합니다.
ANSI/ASHRAE/IES Standard 90.1(저층 주거용 건물을 제외한 부지 및 건물의 에너지 표준)은 미국냉난방공조학회(ASHRAE)에서 발행하는 광범위하게 인정받는 에너지 표준입니다.
ASHRAE 90.1을 주목해야 하는 이유
ASHRAE 90.1은 미국 전역의 건물 에너지 코드의 기준 표준으로 사용되며, 건물 외피, HVAC 시스템, 급탕 시스템, 조명 시스템을 포함한 상업용 건물 구성 요소의 에너지 효율적 성능에 대한 최소 요구사항을 개괄하는 IECC 내 준수 경로 역할을 합니다.
ASHRAE 90.1 표준은 최대 허용 조명 전력 밀도 및 특정 구역에서의 점유 감지 센서 사용을 포함한 최소 조명 제어 요구사항을 규정합니다.
캘리포니아 건물 표준법 Part 6의 Title 24(공식 명칭: 주거용 및 비주거용 건물 에너지 효율성 표준)는 캘리포니아 에너지 위원회(CEC)에서 관리하며, 새로운 에너지 효율 기술과 방법을 반영하기 위해 주기적으로 업데이트됩니다.
Title 24를 주목해야 하는 이유
Title 24는 미국 내 다른 수많은 에너지 코드보다 더욱 엄격한 요구사항을 가진 것으로 잘 알려져 있습니다. Title 24는 난방, 환기, 공조(HVAC), 급탕, 조명을 포함한 건물 건설의 모든 측면에 대해 엄격한 에너지 성능 표준을 준수하도록 규정합니다.
Title 24는 에너지가 낭비되지 않도록 상업용 건물의 특정 구역에서 재실 여부에 따라 조명을 조절하는 점유 감지 센서 설치를 의무화합니다.

Design Guide Key Concepts for Conference Rooms
Designing an energy-efficient lighting control solution for conference rooms involves strategic placement of occupancy sensors to ensure comprehensive coverage of the space.
Designing an energy-efficient lighting system for a conference room involves strategic placement of occupancy sensors to ensure comprehensive coverage. Here are some guidelines to consider:
- Entrance Coverage: Install a wall-mounted sensor near the entrance to detect when someone enters or exits the room. This sensor should be positioned high enough to avoid obstruction from the open door and should not directly face the entrance to avoid false triggers from movement outside the room.
- Table Coverage: Place a ceiling-mounted sensor above the conference table to detect occupancy in the main area of the room. This sensor should be positioned centrally to ensure comprehensive coverage.
- Presentation Area Coverage: If your conference room has a dedicated presentation area, consider installing an additional wall-mounted sensor to cover this space. This sensor should be positioned to avoid any potential obstructions, such as screens or projectors.
- Wall Control: Install a wall control unit near the entrance for manual override or adjustments of the lighting settings. This control should be easily accessible upon entering or exiting the room.
- Avoidance of Obstructions and Interference: Ensure that sensors are not placed near air vents to prevent interference from air flow or vibrations. Also, consider the height and placement of furniture to avoid blocking the sensor’s field of view.
- Integration with Existing Systems: Our occupancy sensors can be integrated with existing lighting systems for seamless operation. They can also be programmed to turn off all lights after a certain period of inactivity, further enhancing energy efficiency.
