Development of 66 student residential apartments and 225m2 of commercial space required to achieve 15% reduction in CO2 emissions according to Plymouth City Council policy CS20.
– 15% reduction in CO2 requirement using Low Zero Carbon Technologies following Plymouth City Council Policy CS20)
– Requirement to ensure future connection to district heat main when available
– HVAC and service requirements for mixed use commercial and student accommodation.
– Client requirement for grid supplied conventional domestic gas central heating and hot water
– Limited space for conventional Low Zero Technologies
– Consultation to understand direction of travel in achieving CO2 emissions targets.
– High level consideraton of design and materials to establish fabric energy efficiencies
– Delivery of feasibility study for Low Zero Carbon Technologies
– IES/SBEM 2012 modeling to esatabilsh compliance
– IES/Radiance used for potential overheating risk
– SAP 2012 calculations for residential elements in study
– Preliminary energy modelling and compliance testing under IES ModelIT/SBEM 2012 /Apache/Radiance and SAP 2013
– Delivery of highly energy efficient residential and commercial spaces maximising Fabric Energy Efficiency in external elements detailing to establish very low energy demand baseline
– Low levels of heat loss through major junctions (using Accredited Construction Details)
– Consideration of glazing strategy to each elevation – Initial specification ensured low heat loss with reductions in solar gain and noise potential.
– Heating and Hot water strategy using natural gas and flue gas heat recovery.
– High efficiency, low loss, heating and hot water distribution systems.
– Maximal use of Power Factor Correction equipment
– Cost efficient, low output initial Internal Lighting design strategy to further reduce energy consumption
– Minimised use of Roof mounted Photovoltaic to 175m2
