Greenlite Building Physics are multi-award winning energy efficiency and thermal comfort consultants with 10yrs experience in the industry sector.
We are passionate proponents of sustainable practices in the construction industry and firmly believe that energy efficiency and thermal comfort should go hand-in-hand as we transition towards a zero carbon economy.
Greenlite Building Physics strongly advocate ‘fabric first’ and ‘architecture first’ approaches to construction, to support you on your journey towards cost efficient, thermally comfortable, low energy buildings.
Greenlite Building Physics were engaged by owner/builder and architect Ian de-Peyrecave of Perry and Bell Architects, London, to aid in the design of a super low energy dwelling in Hampshire. The design intent of the building was to maximise, so far as reasonably possible, space heating and hot water generation through the use of solar energy.
Greenlite Energy Assessors provided concept stage design advice concerning the selection of renewable energy systems and the locating there of, plus HVAC design advice, air tightness and construction fabric recommendations.
The principal purpose of the detailed analysis was to inform the sizing of an active solar heating system, which utilised heating inputs from solar thermal, solar PV and auxiliary sources, and included thermal storage within a large thermal store. The analysis provided a precise estimation of space heating and hot water demand, allowing for the active solar heating system to be sized accordingly.
The ‘Research Acceleration and Demonstration’ (RAD) Building at the University of Nottingham is an ambitious project which provides laboratories, offices and break-out spaces for various groups, as part of the Energy Research Accelerator (ERA) initiative. The 2,500m², £5.4m facility targets both BREEAM Excellent and Passivhaus certification, and if successfully certified, will become the largest working Passivhaus laboratory in the UK.
Greenlite Building Physics worked extensively with building services engineers MIES and Passivhaus consultants Etude to assess the overheating risk of the building under the CIBSE TM52 thermal comfort metric. We later developed these works further to aid Passivhaus certification, by way of calibrating the fan energy used to ventilate and cool the building.
The Art, Architecture and Design Building (East) at the University of Lincoln is a new build construction completed in 2013. Since completion, the gallery area has suffered from chronic overheating issues resulting from very high quotas of glazing and insufficient consideration of the ventilation strategy required to discharge the resulting solar gains.
Overheating within the area was so severe that internal temperatures reached 56°C within the room, rendering it unsuitable for the display of art works.
Greenlite Energy Assessors were appointed by the University of Lincoln to carry out a feasibility study of options which could return the space back to thermal comfort.
Through the use of a dynamic thermal model and computational fluid dynamics software, Greenlite Energy Assessors were able to assess several remedial measures and comment upon their appropriateness.
