BVH HQ,1LASAM Project Writeup 1Lasam is a 5-storey building with a total gross floor area of 2,748.51 m², located at No. 1, Jalan Lasam, Ipoh, Perak. The building serves as the headquarters for Bonanza Venture Holdings (BVH) and has been designed with a wide range of sustainable features that emphasize energy efficiency, water conservation, environmental sustainability, and indoor environmental quality. The architectural layout minimizes the surface area of the façade facing the East and West direction, with glazing intentionally omitted from these orientations. The façade consists of glass, concrete, and brickwork, supported by eggcrate shading, vertical greenery, and a cavity brick wall system. High SRI finishes are applied to both the metal deck roof and reinforced concrete flat roof, each achieving Solar Reflective Index values above 78. Daylighting is a key strategy, with 43.32% of the net lettable area situated within a daylight factor range of 1 to 3.5. Floor-to-ceiling glazing panels are incorporated on both sides of certain office spaces to optimize natural daylight penetration. Natural ventilation forms a significant component of the design, with 41.88% of the gross floor area naturally ventilated. Corridors, lift lobbies, entrances, toilets, pantries, and staircases are intentionally designed for natural ventilation, while air-conditioned office spaces include louvred openable windows to allow occupants the flexibility to choose natural ventilation during conducive periods. Energy efficiency is achieved using Daikin’s high-efficiency VRV-X system serving the 1,386.42 m² air-conditioned area, with outdoor unit COP values ranging from 3.96 to 4.77. Smart controls accessible through a touch panel and web interface allow the maintenance team to manage setpoint temperatures and profiles. The cooling load is 63.98 W/m², while the lighting load is maintained at 3.5 W/m². Motion sensors and lux sensors are installed at corridors and toilets to regulate lighting and reduce unnecessary energy consumption. The building incorporates a 40.25 kWp Solar PV system, which recorded a yield of 1,546.15 kWh/kWp and achieved 27.19% replacement of total building energy consumption for the year 2023. A total of 45,126.10 kWh of electricity was generated in 2023. Water efficiency is supported through water-efficient fittings, digital water meters for early leak detection, and multiple non-potable water systems. A 10 m³ rainwater harvesting tank supplies the water closets, floor cleaning, and landscape irrigation. Greywater recycling is implemented through a system consisting of a 2,700 L raw water tank and a 1,500 L treated water tank, redistributing treated greywater for courtyard irrigation. Condensate water recovery further contributes to non-potable water supply for toilet flushing and irrigation. Environmental sustainability measures include the use of rebar and aluminium with recycled content, with 32.42% of materials by cost containing recycled content. All timber products used for doors are PEFC-certified. Construction waste segregation diverted 50.18% of non-hazardous waste from landfill. The project also provides 24.42% landscape coverage, including vertical greenery that acts as a natural insulator and improves surrounding air quality. Bioswales, covering 26.52% of the building perimeter, manage stormwater runoff and enhance site ecology. The building is located within 500 m of a bus stop and within 1 km radius of at least 10 basic services. Indoor environmental quality is achieved through demand control ventilation that regulates fresh air based on CO₂ sensors. Other notable features such as usage of low-VOC materials, blinds for glare control, prohibiting smoking in the building and mould-prevention measures support occupant well-being. A real time energy and water monitoring system is also present to ensure there is no abnormal usage of resources. A mini herb garden is also planted on the premises for staff usage. Overall, the combination of its design strategies, efficient systems, and ongoing maintenance measures allows 1Lasam to operate as a resource-efficient and environmentally friendly building.
