MULTI OCCUPANCY BUILDINGS PROJECT REPORT
The roof garden also includes an ‘Observatory’ Fully fitted kitchens will feature energy
efficient A+++ rated appliances, and other energy efficiency features will include smart- controlled thermostats, comfort cooling systems and automated blinds. Penthouse apartments will have substantial terraces including winter gardens, hot tubs and elec- tric privacy glass.

The developer is actively trying to encour- age residents to discard their cars with its what’s claimed to be a pioneering rental scheme. However there are 319 car parking spaces packed into a tight basement area, thanks to an APS robotic system which stacks cars efficiently, enabling high density parking.
Renewables
In addition to the solar PVs producing a large chunk of the building’s electricity, ground source and air source heat pumps will provide heat for water, and the building’s ceil- ings will be cooled using a recycled greywater system. In fact all water used in the building will be either rain or greywater harvested; no water will come through the mains, which is projected to save around five million litres per year.
“There are five huge tanks in the basement” says Vyas, adding that all of the appliances “have been carefully considered on water and energy use,” and from toilet fittings to kitchen units they generally range from A+ to A+++.
In addition to the MVHR system sucking up extra solar gain in the building, heat will also be recovered to warm harvested water:

“The more heat we get into space the more energy we produce,” says Vyas. He says this would obviate normal concerns with heat gain from an ETFE roof, adding – “people normally put a fridge on the roof. However with our system the more heat we get, the more heat can be recovered and used.”
Measurement
The building is one of the first in the UK to be assessed under the BRE’s new, comprehen- sive five-star ratings system for housing, the Home Quality Mark. It is no surprise that the architects are hoping to come out with a five- star rating, covering criteria such as comparative running costs, environmental footprint, amenities and wellness. Given that the building is relatively close by the BRE in Watford, it’s likely its academics will take a close interest in the results, to see if turns out to be the exemplar it promises to be. Whether or not it is eventually confirmed as the world’s most sustainable apartment block, residents will be receiving copious amounts of information on how their invest- ment is performing, This data, ranging from wind pressure to heat gain, and gathered from sensors placed during construction, will also give the developers crucial knowledge on what is working and what could be further improved on.
Although detail packages remain to be ironed out in the design, this potential game- changer of a project has already provided the blueprint for Lumiere for its pipeline of future residential schemes, including in Hemel Hempstead.
