Including 5 closely related terms such as energy use, energy generation, and energy generation.
… to the CC report, the current policy requires new homes to achieve a space heating demand of less than 30kWh/m2/year, a total energy use of less than 40kWh/m2/year, and a net zero energy balance on site through use of solar photovoltaics. Evaluation of policy options Seven policy scenarios were assessed for a high-rise building type (16 storeys) through detailed energy and cost modelling. Policy…
… that: • it is possible to achieve net zero carbon homes using best practice on- site solar PV design and specification. Generally, some high-rise buildings may require additional off-site renewable energy generation to achieve a net zero energy balance due to site or design constraints. • It is important to note that a solar tenant model approach, distributing the solar energy generated to all flats, instead…
… homes for a construction cost between 2.4-3.0% more than a home that is compliant with Part L 2021. Cost differences are expected to decrease over time as experience and markets for low carbon buildings grow. • Electricity use calculated by energy modelling relates well to metered electricity use data, supporting the use of total energy use targets. Total energy use targets from RIBA, UKGBC…
… --- --- Sustainable Energy and Construction – Current Policy requirement This evidence base focuses on Sustainable Energy and Construction and in particular on the requirements for new residential developments. Specifically, it assumes that the residential development proposals will be required to achieve Net Zero Carbon by accomplishing: • A space heating demand of less than 30kWh/m2/annum; • A total…
… energy use of less than 40kWh/m2/annum; and • On-site renewable generation to match the total energy use, with building mounted solar PV. The technical assessment (Section 2.0) demonstrates that it is technically feasible for a high-rise building type to: • Achieve a space heating demand between than 15-20kWh/m2/annum • Achieve a total energy use of less than 35kWh/m2/annum • Install…
