Design of Facades

The concept behind the design of the office façades is that they should be a formal and elegantly articulated statement. They have also been designed to provide a high level of environmental control within the office buildings, minimising solar gain and reducing imposed air handling energy requirements.

A solid insulated recessed band running parallel with each floor plate provides high-performance insulated band and increases the percentage of insulated area across the façade. This allows a simple provision of floor to ceiling glass on each floor plate, provided in high performance triple glazed unitised faced units.

The façade is completed with natural stone at the base and at edge details.

Number One Ballsbridge is to achieve LEED Gold Accreditation and has been designed as a sustainable development in line with the LEED assessment criteria:

Location and Transportation

To encourage development in locations shown to have multimodal transportation choices or otherwise reduced motor vehicle use, thereby reducing greenhouse gas emissions, air pollution, and other environmental and public health harms associated with motor vehicle use.

The development allows access to quality transit,Number One Ballsbridge is located in a well serviced and connected brownfield city centre site. Bicycle facilities are provided to all areas of the mixed-use development, with associated shower and changing facilities. In accordance with LEED definition, a reduced parking footprint to minimise the environmental harms associated with parking facilities, including automobile dependence, land consumption, and rainwater runoff has been integrated. Finally, green vehicles are designated 5{c76394f874f8ea7c6608a5e0a996fcecb0d322facfcf332534fc94552659ba09} of all parking spaces used by the project as preferred parking for green vehicles. Installation of electrical vehicle supply equipment (EVSE) in 2{c76394f874f8ea7c6608a5e0a996fcecb0d322facfcf332534fc94552659ba09} of all parking spaces is included in the project.

Sustainable Sites

The construction activities of the site are undertaken in accordance with the Sustainable Site Activity identified by LEED, including construction activity pollution prevention to reduce pollution from construction activities by controlling soil erosion, waterway sedimentation, and airborne dust; environmental site assessment, to protect the health of vulnerable populations by ensuring that the site is assessed for environmental contamination and that any environmental contamination has been remediated.

Site Development

The mixed-use development design and execution seeks to achieve the correct site development principles seek out in the LEED assessment criteria, including the objective to protect or restore habitats, conserving existing natural areas and restore damaged areas to provide habitat and promote biodiversity; open space to create exterior open space that encourages interaction with the environment, social interaction, passive recreation, and physical activities; rainwater management to reduce runoff volume and improve water quality by replicating the natural hydrology and water balance of the site, based on historical conditions and undeveloped ecosystems in the region; heat island reduction to minimise effects on microclimates and human and wildlife habitats by reducing heat islands; light pollution reduction, to increase night sky access, improve nighttime visibility, and reduce the consequences of development for wildlife and people.

Finally, a site master plan is to be put in place to ensure that the sustainable site benefits achieved by the project continue, regardless of future changes in programs or demographics, including tenant design and construction guidelines to educate tenants in implementing sustainable design and construction features in their tenant improvement build-outs.

Water Efficiency

A general LEED requirement to reduce outdoor water consumption is being integrated into the development, including indoor water use reduction, outdoor water use reduction and building – level water metering to support water management and identify opportunities for additional water savings by tracking water consumption.

Energy and Atmosphere

The development will include energy performance features including enhanced commissioning and verification to support the design, construction, and eventual operation of a project that meets the owner’s project requirements for energy, water, indoor environmental quality, and durability; building-level energy metering to support energy management and identify opportunities for additional energy savings by tracking building-level energy use; enhanced refrigerant management to reduce stratospheric ozone depletion.

The development seeks to optimise energy performance to achieve increasing levels of energy performance beyond the prerequisite standard to reduce environmental and economic harms associated with excessive energy use & to support energy management and identify opportunities for additional energy savings by tracking building-level and systemlevel energy use. Demand response is integrated into the BMS to increase participation in demand response technologies and programs that make energy generation and distribution systems more efficient, increase grid reliability, and reduce greenhouse gas emissions.

Finally, renewable energy production to reduce the environmental and economic harms associated with fossil fuel energy by increasing self-supply of renewable energy is integrated in the development CHP plant.

Materials and Resources

The construction and specification of the development includes storage and collection of recyclables, to reduce the waste that is generated by building occupants and hauled to and disposed of in landfills; construction and demolition waste management planning, to reduce construction and demolition waste disposed of in landfills and incineration facilities by recovering, reusing, and recycling materials; building life-cycle impact reduction, to encourage adaptive reuse and optimise the environmental performance of products and materials.

The specification of the development seeks building product disclosure and optimisation, to encourage the use of products and materials for which life-cycle information is available and that have environmentally, economically, and socially preferable life-cycle impacts. To reward project teams for selecting products from manufacturers who have verified improved environmental life-cycle impacts.

Building Product Disclosure and Optimisation also looks to encourage the selection of products for which the chemical ingredients in the product are inventoried using an accepted methodology and for selecting products verified, to minimise the use and generation of harmful substances and to reward raw material manufacturers who produce products verified to have improved life-cycle impacts.

Indoor Environmental Quality

The LEED accreditation requires the Number One Ballsbridge development to adopt minimum indoor air quality performance, to contribute to the comfort and well-being of building occupants by establishing minimum standards for indoor air quality (IAQ), to prevent or minimise exposure of building occupants, indoor surfaces, and ventilation air distribution systems to environmental tobacco smoke and to promote occupants’ comfort, well-being, and productivity by improving indoor air quality.

Low-emitting materials are specified, to reduce concentrations of chemical contaminants that can damage air quality, human health, productivity, and the environment. A construction indoor air quality management plan is in place to promote the wellbeing of construction workers and building occupants by minimising indoor air quality problems associated with construction and renovation.

Other areas of indoor environmental quality to be delivered in the development, in accordance with the LEED assessment criteria, include thermal comfort standards, to promote occupants’ productivity, comfort, and well-being by providing quality thermal comfort; interior lighting standards, to promote occupants’ productivity, comfort, and well-being by providing high-quality lighting; daylight standards, to connect building occupants with the outdoors, reinforce circadian rhythms, and reduce the use of electrical lighting by introducing daylight into the space and quality views, to give building occupants a connection to the natural outdoor environment by providing quality views.
