Knights Place & Rowan House – Monitoring Building Performance Evaluation
Funded by Technology Strategy Board (TSB) The main objectives : • To monitor the environmental, energy & comfort performance over a 2 year period • To compare their performance in use against the design intent • 3 flats at Knights Place & 2 flats Rowan House
Ventilation, Heating, Hot Water, Cooling Strategy • Mechanical Ventilation with Heat Recovery (MVHR) Ventilation mechanique avec recuperation de chaleur
• No Main Heating System Small heater battery in supply air duct, fused spurs up
back
• Hot Water = Solar Thermal with PV pump electric back up
• Summertime Operation – Natural Ventilation & Thermal Mass
Metering & Sub Meters! • Mains Electricity and Mains Water
• Energy Sub Metering of Lighting Small Power Sockets Ventilation System Cooking Hot Water System • Captures energy in kwh every 5 minutes • Loads data onto a hub • Data transmitted to Energy Savings Trust web site
Performance and Comfort Monitoring • Temperature & Humidity Monitoring • CO2 Monitoring • Solar Panel Performance Monitoring Pyranometer reading available solar energy Energy & flow sensors reading solar energy captured by solar panel
• MVHR System Performance Monitoring • MVHR = mechanical ventilation with heat recovery ventilation mechanique avec recuperation de chaleur
Ventilation System Monitoring • 5 Temperature & Humidity Data Loggers in each duct – fresh air intake, supply, extract, exhaust & after heater battery • Air Balance Check • CO2 capture check in winter
Design & Construction Review / Tenant survey & Interview • SAP, PHPP design and construction review Review of designs, details and energy calculations • Installation check of services, fittings and commissioning • Tenant interviews, walkthroughs, BUS questionnaires • BUS = Building User Survey • Tenant Handover and training review
Fabric Testing & Monitoring • Air Permeability Testing 2 tests – year 1 and year 2 • Thermal Imaging Survey this winter • Fabric Uvalue Monitoring via Dynamic Flux Sensors
Additional Studies at Rowan House EMR (electro magnetic radiation) & Electric Field Study
