LEED & WELL : O-NES TOWER

O-NES TOWER has set a goal to achieve LEED and WELL certification for Core and Shell project, which has an objective not only to improve the built environment but also design for better health and well-being of occupants.

This guideline will help all building occupants understand and familiarize themselves with and benefit from LEED and WELL features that are incorporated into the project, as well as develop their space to optimize health and well-being.

HEALTHY HUB

To focus extremely on the living quality, O-NES TOWER also aims to achieve “WELL” Certification for Core and Shell projects at GOLD level, the objective is to improve built environment conditions for better health and well-being of occupants. WELL is developed by the International Well Building Institute (IWBI) and is currently adopted in many countries. WELL design and construction criteria are categorized into 7 following concepts.

AIR

WATER

LIGHT

FITNESS

COMFORT

MIND

AIR

O-NES TOWER intends to limit the pollutant and contaminant concentrations on the project’s indoor air quality throughout the design and specification, material selection, and building operation policy. The building is designed to prevent dust and moisture that can be entering the building by means of while the ventilation system which is designed to provide sufficient and quality fresh air. No asbestos and mercury-containing materials and equipment are specified. Low-emitting paints, coatings, adhesives, sealants, flooring, and furniture are selected for the building interior. The policy is set to maintain indoor air quality.

Ventilation Effectiveness (Precondition) / Air Filtration (Precondition) / Increased Ventilation (Optimization) / Direct Source Ventilation (Optimization) / Outdoor Air Systems (Optimization)

LEED crosswalk to Indoor Air Quality requirements.

Healthy Entrance (Precondition), LEED crosswalk

LEED crosswalk to Indoor Air Quality requirements.

Moisture Management (Precondition)

Thailand is located in a tropical climate zone which characterizes as a hot, generally high humidity, and high precipitation area. The project considers design principles and strategies to mitigate water damage throughout the exterior and interior water management, HVAC system sizing, plumbing which is designed to prevent leaks, and Material Selection and Protection.

Material selection

VOC Reduction (Precondition)

LEED crosswalk to Low-Emitting Materials requirement.

Fundamental Material Safety (Precondition)

No asbestos and mercury-containing materials and equipment are specified throughout the building. Also, the lead-free water piping and fixture were installed for the project’s potable water system.

Building operation policy

Air Quality Standard (Precondition)

The performance verification occurs on-site prior to the residents move-in and the air quality must achieve the WELL standard limit.

Smoking Ban (Precondition)

LEED crosswalk to Indoor Air Quality requirements.

Microbe And Mold Control (Precondition)

The building management team will set up a policy for quarterly inspection of the cooling coil in the project including the tenant area.

Construction Pollution Management (Precondition)

To prevent any pollutant inadvertently introduced into the space during the construction period, WELL standard requires to have HVAC duct be sealed and protected, thus, dust guards or collectors are used for saws and other tools as well as all active areas of work are isolated from other spaces by the temporary barriers, and absorptive materials arestored in the designated area. All contractors must comprehend and confirm the WELL requirements implementation.

WATER

The project assures that potable water delivered to the project area is clear and free from coliforms, including E. coli through the water filtration systems. Also, to support the drinking water promotion, drinking water dispensers with a high-efficiency filtration system are provided on each floor to serve the project’s occupants.

Fundamental Water Quality (Precondition)

An on-site water test will be conducted after the construction completion to ensure that the potable water quality meets WELL’s turbidity and total coliforms requirements.

Inorganic Contaminants / Organic Contaminants / Agriculture Contaminants / Public Water Additives (Precondition) / Water Treatment / Drinking water promotion (Optimization)

A drinking water purifier is provided on every floor. The purifier is comprised of the activated carbon filter, sediment filter, and a filter rated by NSF to remove microbial cysts, will be provided with the system that can reduce organic, inorganic and agricultural chemical contaminations and public water additives such as chlorine and fluoride.

LIGHT

Light especially natural light is the main driver of the circadian system, which starts in the brain and regulates physiological rhythms throughout the body’s tissues and organs, affecting hormone levels and the sleep-wake cycle.

Electric Light Glare Control (Precondition)

The lighting level is sufficiently designed based on the activity of the area. Also, all the lighting fixture in the project was limited to UGR less than 19.

Solar Glare Control (Optimization) / Right To Light (Optimization)

More than 75% of regularly occupied spaces are within 7.5-m proximity to view windows. Additionally, the project provides interior blinds at all windows in the tenant office area to prevent solar glare.

FITNESS

O-NES TOWER has an intention to support periods of physical activity into every step. Integrating elements of active design into the building and site, such as benches, public art, can create pedestrian-friendly environments and encourage physical activity.

Exterior Active Design (Optimization)

The project is surrounded by density and diverse uses such as church, hospital, supermarket, museum, school, and restaurant. Also, the plaza is placed in front of the building to encourage daily pedestrian activity.

COMFORT

The indoor environment should be a place of comfort. O-NES TOWER focuses on significantly reducing the most common sources of physiological disruption, distraction, and irritation and on enhancing acoustic, and thermal comfort to prevent stress and injury and facilitate comfort, productivity, and well-being.

Accessible Design (Precondition)

O-Nes projects meets local accessibility laws and/or codes without exclusions or exemptions.

Thermal Comfort (Precondition)

The project designs the HVAC system in accordance with ASHRAE Standard 55-2013 to meet the acceptable thermal comfort for mechanical ventilated space.

Exterior Noise Intrusion (Precondition) / Internally Generated Noise (Optimization)

Noise plays an important role in disruptive relaxation and can be a source of stress and a risk factor for certain health outcomes. Thus, O-NES TOWER focuses on the façade design to prevent exterior noise, while the location and specification of the VRF system, booster fan, and HEX help to reduce the internally generated noise.

Olfactory Comfort (Optimization)

The project was designed to prevent strong odors from all restrooms, janitorial closets, kitchens, cafeterias, and pantries entering to the workspaces by having intermediate areas.

MIND

Because the mind plays a vital role in an individual’s overall health and well-being, an atmosphere that supports a healthy mental state can provide significant psychological and physical benefits.

Health And Wellness Awareness / Integrative Design / Beauty And Design I / Biophilia I – Qualitative (Precondition)

To create a WELL understanding among the project stakeholders, the project provides a charrette and communicates regularly to discuss the health and wellness strategies and outline development plan, including O&M and building policy requirements. Also, the design is representing human delight, a celebration of culture, a celebration of spirit, and a celebration of place.

Innovation (Optimization)

WELL AP: Project works together with the WELL Accredited Professional to ensure that all of the targeted WELL intentions have are present in O-NES TOWER.

WELL Education: The project will provide free tours of the WELL Certified space.Green Building Rating Systems: The project achieves LEED certification.

Waste Management: The project provides a recyclable waste storage area on the ground floor and states the policy of a hazardous waste (which includes chemical container, battery and etc.) management plan according to U.S. Environmental Protection Agency and waste stream management plan.
