The HHC is committed to reducing the impact that our buildings have on the environment. We also identify opportunities where reducing emissions also assists in reducing costs for tenants; for example, the use of gas hot water systems in our Southport development reduces carbon emissions while reducing electricity bills for our future tenants. All developments will utilise compact fluorescent and other low wattage lighting, include water tanks to reduce water consumption, and where possible will use solar or gas hot water systems to reduce electricity bills. Just by producing smaller, higher density product, we are reducing the footprint of our buildings; the efficient use of space reduces unnecessary materials (and thus embodied emissions) and saves land from clearing. We are also looking at implementing more advanced technologies, such as grey water reticulation, water treatment, green roofs and solar power generation where the higher costs can be justified.
