office building energy storage cost vs benefit calculation in New Zealand

How much energy does a New Zealand building use?

energy useHistorical data indicates that the energy use of a typical New Zealand commer-cial building is 100–300 kWh/m2/yr. This is consistent with NZ buildings200 kWh/m2/yr for existing office bui l/May 2013distribution of EUIs, with some much lower and some much higher than previousl

Why is thermal storage important in New Zealand home construction?

In New Zealand home construction follows largely timber construction, having low thermal mass, which leads to significant indoor temperature fluctuations even when dwellings are properly insulated. Thermal storage will provide significant energy benefits in low thermal mass buildings.

Can energy storage materials be encapsulated in New Zealand?

New Zealand has tremendous knowledge in the development of energy storage materials (PCM); their encapsulation and use. The work which has been conducted at University of Auckland over the last 20 years has generated significant knowledge that could be used for true implementation within a very limited time period.

Why do building owners pay a premium for energy-efficient buildings?

Building owners can desire energy-efficient buildings and are therefore willing to pay a premium for it. Similar to the argument for increases in rent, asset values increases are a function of rent increases, i.e. the asset value is equal to the sum of all future cash flows, all else being equal.

Do distributed battery energy storage systems work in New Zealand?

A recent study on distributed battery energy storage systems in New Zealand shows that if such systems are appropriately configured, they can respond faster than current providers of instantaneous reserve, recovering frequency faster and stabilising the system with fewer oscillations (Transpower, 2019a). 49.8 Hz and 50.2 Hz.

How much energy does space heating use in New Zealand?

Importantly, in New Zealand, space heating was found to average 34% of total household energy use (23). The most common forms of space heating are wood burners, convection plug-in electric heating systems and heat pumps.

ENERGY USE CALCULATION GUIDE

For Interiors ratings, it is recognised that the majority of energy consumption will generally be attributable to non-HVAC energy end uses, and it is therefore expected that the majority of

Cost benefit analysis

Like early analyses undertaken with respect to office buildings, we assumed that EPR requirements would indirectly incentivise building owners to invest in energy efficiency

The benefit of using energy storage in New Zealand’s homes

Through both experimentation and simulation we have shown that energy storage is effective in a moderate climate, such as the atmospheric conditions over much of New Zealand.

Cost-benefit analysis of distributed energy resources in New

This report builds on our previous report for Transpower, which assessed the potential value of distributed energy resources in New Zealand (Reeve, ). For this report, we have updated

The need for energy storage: Firming New Zealand’s

Concept Consulting’s modelling shows that without thermal generation from the Rankine units as part of New Zealand’s energy storage solution, wholesale electricity prices would likely be 60%

Upgrading New Zealand’s existing office buildings

This study presents a comprehensive environmental assessment of New Zealand’s office building stock using a stock aggregation approach based on LCA results of

Value Case for Sustainable Building in New Zealand

Sustainable building needs to be implemented on a cooperative and integrated basis by client, design team and contractor. Planning for sustainable building needs to take place as early as

The benefit of using energy storage in New Zealand’s homes

Within this context, performing Thermal Energy Storage (TES) in buildings has become a priority. Energy can be mainly stored in three forms: sensible heat, latent heat or thermochemical heat
